AB  - The "corrected accelerated service life test for hydrogen evolution reaction" (CASLT-HER), designed for application of certain electrode materials as cathodes in the cell for alkaline water electrolysis in 30 % KOH at 80 degrees C, was performed at electrodeposited NiSn alloy and Ni 40 mesh electrodes. The Ni 40 mesh was slightly etched, while the NiSn alloy coating was electro-deposited from the bath containing pyrophosphate, glycine, SnCl2 and NiCl2 onto Ni 40 mesh to the thickness of approximately 40 mu m. It is shown that the NiSn cathode possess from maximum 0.77 V to minimum 0.30 V better over-potential than the Ni 40 mesh electrode during the 5 years of their exploitation at the conditions of industrial alkaline water electrolysis. It is also shown that both electrodes should be held at j = -0.3 A cm(-2) for at least 5 h in order to establish stable overpotential response. The limiting overpotential values for applying cyclic voltammetry (CVs, to mimic "polarity inversion") should be determined in a separate experiment before the CASLT-HER and should be adjusted during the application of CVs.

AB  - The Ag, Pd and AgPd alloys of different morphologies and compositions were electrodeposited onto Au and glassy carbon (GC) disc electrodes from the solution containing 0.001 M PdCl2 + 0.04 M AgCl + 0.1 M HCl + 12 M LiCl under the conditions of non-stationary (RPM = 0, samples AgPd1 and AgPd2) and convective diffusion (RPM = 1000, sample AgPd3). Electrodeposited alloy layers were characterized by the scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), and X-ray photoelectron spectroscopy (XPS). Oxygen reduction reaction (ORR) was investigated on all coatings in 0.1 M NaOH solution saturated with oxygen. The j-E curves for the ORR were recorded by two procedures: (1) samples were cycled with 5 mV s(-1) from open circuit potential (OCP) to -0.8 V for Ag and AgPd alloys (or -0.6 V for pure Pd) and back; (2) samples were cycled with 5 mV s(-1) from open circuit potential to 0.45 V (formation of Ag2O, in the case of Pd formation of PdO and PdO2), from 0.45 V to -0.60 V and back to the OCP. Significant catalytic activity for the Ag and AgPd alloys was detected after cycling electrodes in the potential region of Ag2O formation and reduction. Increase of the catalytic activity for AgPd alloys was, for the first time in the literature, ascribed to the presence of a certain amount of Ag2O which could not be completely reduced during the reverse sweep from 0.45 V to -0.6 V. Catalytic activity of AgPd alloys was found to be closely related to the amount of non-reduced Ag2O (most probably in the form of Ag-hydroxide). In the absence of such treatment, the catalytic activity for the ORR on electrodeposited Ag and AgPd alloy coatings was not detected.

AB  - Electrodeposited NiSn alloy coatings onto Ni 40 mesh substrate were tested for application as cathodes and anodes in the cell for alkaline water electrolysis in 30 wt% KOH at 80 degrees C. The "accelerated service life test" (ASLT) was performed for the hydrogen evolution reaction (HER), as well as for the oxygen evolution reaction (OER), and compared to that recorded for the Ni coating (Ni-dep) and Ni-mesh for both reactions. The morphology and chemical compositions of the NiSn and Ni coatings were investigated by scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS), while their surface composition was investigated by X-ray photoelectron spectroscopy (XPS) before and after the ASLT for both reactions, respectively. By measuring the potential at j = 0.3 A cm (-2) it was shown that during the ASLT the NiSn alloy coating catalytic activity for the HER decreases (about 24 mV after 25 cycles), while the catalytic activity for the OER increases (about 50 mV after 25 cycles), so that the cell voltage decreases for about 26 mV. The Ni-dep and Ni-mesh electrodes catalytic activity was found to increase for the HER (for about 103 mV), as well as for the OER (for about 52 mV) during the ASLT. Hence, the cell voltage for the Ni-dep and Ni-mesh electrodes decreased from 2.402 V to 2.245 V during the ASLT, while that for the NiSn electrode decreased from 1.967 V to 1.941 V. The cell voltage saving with the NiSn electrodes amounts to about 435 mV before the ASLT and about 304 mV after the ASLT. SEM results showed that no changes in the morphology of as prepared samples could be detected after the ASLTs for both reactions. EDS analysis confirmed that some changes occurred during the ASLT, particularly for the oxygen content in the surface layer. Similar conclusions were made from the XPS analysis.

AB  - The AgPd alloys were electrodeposited onto Au and glassy carbon disc electrodes from the solution containing 0 001 mol dm(-3) PdCl2 + 0.04 mol dm(-3) AgCl + 0.1 mol dm(-3) HCl + 12 mol dm(-3) LiCl under the non-stationary diffusion (quiescent electrolyte) and convective diffusion (omega = 1000 rpm) to the different amounts of charge and at different current densities. Electro-deposited alloy layers were characterized by the anodic linear sweep voltam-metry (ALSV), scanning electron microscopy, energy dispersive X-ray spectro-scopy (EDS) and X-ray photoelectron spectroscopy (XPS). The compositions of the AgPd alloys determined by the EDS were almost identical to the theoretically predicted ones, while the compositions obtained by XPS and ALSV analysis were similar to each other, but different from those obtained by EDS. Deviation from the theoretically predicted values (determined by the ratio j(L)(Pd)/j(Ag)) was more pronounced at lower current densities and lower charges of AgPd alloys electrodeposition, due to the lower current efficiencies for alloys electrodeposition. The ALSV analysis indicated the presence of Ag and Pd, expressed by two ALSV peaks, and in some cases the presence of the additional peak, which was found to correspond to the dissolution of large AgPd crystals, formed at thicker electrodeposits (higher electrodeposition charge), indicating, for the first time, that besides the phase structure, the morphology of alloy electrodeposit could also influence the shape of the ALSV response. In addition to Ag and Pd, the XPS analysis confirmed the presence of AgCl at the surface of samples electrodeposited to low thicknesses (amounts of charge).

AB  - The hydrogen evolution reaction (HER) was studied in 0.5 M H2SO4 at 25 degrees C on Pd electrodeposited onto Ti2AlC substrate, as an excellent substrate due to its high conductivity and high stability in concentrated sulfuric acid. Pd was electrodeposited onto Ti2AlC by pulse technique from the solutions containing different concentrations of PdCl2 in 1 M NH4Cl. It was shown that in all investigated solutions Pd electrodeposition occurs by the diffusion-controlled 3D nucleation and growth. Two types of Pd electrodeposits were submitted to the study of the HER by the polarization measurements and the electrochemical impedance spectroscopy (EIS). The surface of Pd samples was characterized by scanning electron microscopy (SEM), by energy dispersive X-ray spectroscopy (EDS) and by atomic force microscopy (AFM). High catalytic activity for the HER was observed for all investigated samples. The Tafel slope of -64 mV dec(-1) was recorded for the Pd layer electrodeposited at 20 mV vs. saturated calomel electrode (SCE) for 5 s, mainly composed of isolated hemispherical 3D Pd centers and dendrites (sample (2)), while for Pd electrodeposit with the theoretical thickness of 1000 nm (sample (1)) Tafel slope of -143 mV dec(-1) was detected. All Tafel slopes recorded for the investigated samples could be explained by the Volmer-Tafel mechanism for the HER assuming Temkin adsorption isotherm, with either of the steps (Volmer or Tafel step) being the rate-determining one. By the analysis of the EIS results similar slopes for the E vs. log (R-F)(-1) dependences were observed for all investigated samples respectively, while the electrochemically active surface area (EASA), obtained by the integration of the charge for Pd-oxide reduction was found to be the highest for the sample (1). The exchange current densities corrected for the EASA were presented for all samples.

AB  - The oxygen evolution reaction (OER) was studied at pure Ni and Ni-(Ebonex/Ir) composite coatings in 1 M NaOH solution at 25 degrees C. Ni-(Ebonex-supported Ir) coatings were electro-deposited from a nickel Watts bath containing different concentrations of suspended Ebonex/Ir particles (0-2 g dm(-3)) onto a Ni 40 mesh substrate. The surface morphology of the coatings was examined by scanning electron microscopy (SEM), the surface composition by energy dispersive X-ray spectroscopy (EDS), X-ray powder diffraction (XRPD) and Xray photoelectron spectroscopy (XPS), whereas the electrochemical properties were studied by electrochemical impedance spectroscopy (EIS), polarization measurements and cyclic voltammetry (CV). It was shown that the roughness factor of Ni-(Ebonex/Ir) composite coatings calculated relative to the surface area of the pure Ni sample increased with the increasing content of Ebonex/Ir particles in the bath to a maximum value of 40.6. All samples displayed a Tafel slope of about 60 mV dec(-1) in the potential range corresponding to lower current densities for the OER. The increase of the apparent activity for the OER at Ni-(Ebonex/Ir) coatings compared with the pure Ni coating was attributed only to the increase of the electrochemically active surface area. Although the pure Ni coating initially exhibited higher intrinsic catalytic activity for the OER than the composite coatings, it also showed a drastic loss of activity after subjecting to continuous oxygen evolution at j = 50 mA cm(-2) for 24 h (Delta E = 395 mV). At the same time, the OER overpotential at Ni-(Ebonex/Ir) coatings only negligibly increased after the stability test (Delta E = 22 mV). The improved retention of catalytic activity observed with Ni-(Ebonex/Ir) coatings was ascribed to the presence of IrO2 which inhibited the formation of the inactive gamma-NiOOH phase.

Ni-(Ebonex-supported Ir) coatings were electro-deposited from a nickel Watts bath containing different concentrations of suspended Ebonex/Ir particles (0-2 g dm(-3)) onto a Ni 40 mesh substrate. The surface morphology of the coatings was examined by scanning electron microscopy (SEM), the surface composition by energy dispersive X-ray spectroscopy (EDS), X-ray powder diffraction (XRPD) and Xray photoelectron spectroscopy (XPS), whereas the electrochemical properties were studied by electrochemical impedance spectroscopy (EIS), polarization measurements and cyclic voltammetry (CV). It was shown that the roughness factor of Ni-(Ebonex/Ir) composite coatings calculated relative to the surface area of the pure Ni sample increased with the increasing content of Ebonex/Ir particles in the bath to a maximum value of 40.6.

AB  - In this work, the hydrogen evolution reaction (HER) was studied on Ru coated Ti2AlC electrodes in 1.0 mol dm(-3) H2SO4 at 25 degrees C. Ti2AlC was found to be a highly stable substrate in sulfuric acid solutions due to the formation of a passivating oxide layer on the surface, which was confirmed by the X-ray photoelectron spectroscopy (XPS) analysis of as-prepared and anodically treated Ti2AlC samples. Ru films were electrodeposited onto Ti2AlC substrates by cycling the potential of Ti2AlC in the solution containing 0.01 mol dm(-3) RuCl3 + 0.1 mol dm(-3) H2SO4 between -0.5 V and 0.4 V vs. a saturated calomel electrode (SCE) at the sweep rate of 20 mV s(-1). Four Ru/Ti2AlC samples were prepared, obtained at 5, 10, 15 and 20 cycles of Ru electrodeposition. Characterization of samples was performed by scanning electron microscopy (SEM) and cyclic voltammetry (CV), while the thickness of the electrodeposited Ru layers was determined by atomic force microscopy (AFM). It was found that the most compact sample with the thickness of about 0.42 mu m was obtained after 5 cycles. Electrochemical impedance spectroscopy (EIS) and steady-state polarization measurements showed that all Ru/Ti2AlC electrodes were exceptionally active for the HER. A Tafel slope of about -60 mV dec(-1) was observed on all polarization curves in the range of high cathodic current densities. Based on formal kinetics analysis, an appropriate mechanism for the HER on Ru/Ti2AlC was suggested.

AB  - The aim of this study was to gain a better understanding of the feasibility of partial replacement of dichromate, Cr(VI), with phosphate buffer, focusing on the cathode reaction selectivity for hydrogen evolution on mild steel and Fe-Mo cathodes in undivided cell for chlorate production. To evaluate the ability of phosphate and Cr(VI) additions to hinder hypochlorite and chlorate reduction, overall current efficiency (CE) measurements in laboratory cell for chlorate production on stationary electrodes were performed. The concentration of hypochlorite was determined by a conventional potentiometric titration method using 0.01 mol dm(-3) As2O3 solution as a titrant. The chlorate concentration was determined by excess of 1.0 mol dm(-3) As2O3 solution and excess of arsenic oxide was titrated with 0.1 mol dm(-3) KBrO3 solution in a strong acidic solution. Cathodic hypochlorite and chlorate reduction were suppressed efficiently by addition of 3 g dm(-3) dichromate at both cathodes, except that Fe-Mo cathode exhibited higher catalytic activity for hydrogen evolution reaction (HER). The overvoltage for the HER was around 0.17 V lower on Fe-Mo cathode than on mild steel at the current density of 3 kA m(-2). It was found that a dichromate content as low as 0.1 g dm(-3) is sufficient for complete suppression of cathodic hypochlorite and chlorate reduction onto Fe-Mo catalyst in phosphate buffering system (3 g dm(-3) Na2HPO4 + NaH2PO4). The overall current efficiency was practically the same as in the case of the presence of 3 g dm(-3) dichromate buffer (98%). However, for the mild steel cathode, the overall current efficiency for the chlorate production was somewhat lower in the above mentioned mixed phosphate + dichromate buffering system (95%) than in the pure dichromate buffering solution (97.5%).

AB  - In order to examine the intrinsic catalytic activity and durability of the electrodeposited NiSn alloy electrodes and the electrodeposited Ni as a reference electrode material for the oxygen evolution reaction (OER) in alkaline solutions, a comparative investigation was performed. A series of NiSn electrodes were prepared by electrodeposition of NiSn alloys at different current densities onto a Ni40 mesh substrate. The surface morphology and chemical composition were studied by scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS). The electrochemical surface characteristics were studied by cyclic voltammetry in order to find interdependence between the nickel oxyhydroxide surface electrochemistry and the activity of the electrode for the OER Quasi steady-state polarization measurements and electrochemical impedance spectroscopy (EIS) were used to determine kinetically significant parameters including the Tafel slopes and exchange current densities. Two well-defined Tafel slopes, the same for all investigated NiSn electrodes, were observed at the polarization curves, indicating that the OER was controlled by the same mechanism. It was demonstrated that any anodic polarization pretreatment led to a shift of the anodic and cathodic current peaks corresponding to the Ni(II)/Ni(III) redox transition towards cathodic potentials and, consequently, to some activation of the NiSn electrodes. The opposite behavior was obtained for the Ni electrode. Prolonged anodic polarization led to a loss of the initial catalytic activity of the Ni electrode, which was explained by the increase in the portion of gamma-NiOOH at the Ni electrode surface. Among the investigated NiSn electrodes, the NiSn100 electrode, prepared by electrodeposition at the highest cathodic current density of - 100 mAcm(-2), exhibited the highest apparent catalytic activity for the OER, entirely due to surface roughness effects. Despite the fact that the NiSn electrodes did not exhibit better intrinsic catalytic activity than Ni, their high stability during the OER and acceptable apparent activity made them promising anodes for alkaline water electrolysis.

AB  - The hydrogen evolution reaction (HER) was studied at electrodeposited Ni and Ni-(Ebonex/Ir) composite coatings in 1 mol dm(-3) NaOH solution at 25 degrees C. The Ni-(Ebonex/Ir) coatings were electrodeposited from a nickel Watts type bath containing different amounts of suspended Ebonex/Ir(30 wt.%) powder particles (0-2 g dm(-3)) onto a Ni 40 mesh substrate. The electrodes were investigated by cyclic voltammetry (CV), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), electrochemical impedance spectroscopy (EIS) and polarization measurements. It was shown that the roughness factor of coatings increased to a maximum value of 27 with increasing the concentration of Ebonex/Ir particles in the deposition bath, while that of a pure Ni coating was found to be 3.2. In the whole potential range of the HER only one Tafel slope of about -120 mV dec(-1) was observed at all polarization curves. Considerably improved intrinsic catalytic activity for the HER compared to pure Ni was achieved with the composite coating deposited from the bath with the lowest concentration of Ebonex/Ir particles (0.1 g dm(-3)). Further enhancement of the apparent catalytic activity for the HER of Ni-(Ebonex/Ir) composite coatings obtained at higher concentrations of suspended Ebonex/Ir particles in the bath was attributed only to the increase of their electrochemically active surface area.

AB  - In this work the "service life test" (SLT) of the NiSn alloy coatings as cathodes for the hydrogen evolution reaction (HER), deposited onto Ni 40 mesh at different current densities from the bath containing 0.1 mol dm(-3) SnCl2 + 0.3 mol dm(-3) NiCl2 + 0.6 mol dm(-3) K4P2O7 + 0.3 mol dm(-3) NH2CH2COOH at 50 degrees C, was investigated and compared with that recorded for the commercial Ni-RuO2 De Nora's (DN) cathode. The morphology and chemical compositions of all NiSn samples were investigated by SEM and EDS techniques before and after the SLT. HER during the SLT has also been monitored by EIS technique. The chemical compositions of surfaces of all NiSn alloy samples, as well as EIS results, were found to depend on the number of cycles performed during the SLT. The decrease of their catalytic activity for the HER in 32 wt.% NaOH at 90 degrees C with increasing the number of cycles (about 20-25 mV after 25 cycles) was practically identical to that for DN cathode, while NiSn samples deposited at -30 mA cm(-2), -60 mA cm(-2) and -100 mA cm(-2) possessed lower overpotential for the HER before and after SLT in comparison with that for the DN cathode. It is confirmed by the SEM-EDS and EIS analysis of the NiSn samples that the minor loss of the catalytic activity for the HER is the consequence of the change of chemical composition of NiSn coatings and decrease of the active surface area. This decrease is ascribed to partially eroded NiSn coatings due to oxygen evolution during the SLT.

abstract = "In this work the "service life test" (SLT) of the NiSn alloy coatings as cathodes for the hydrogen evolution reaction (HER), deposited onto Ni 40 mesh at different current densities from the bath containing 0.1 mol dm(-3) SnCl2 + 0.3 mol dm(-3) NiCl2 + 0.6 mol dm(-3) K4P2O7 + 0.3 mol dm(-3) NH2CH2COOH at 50 degrees C, was investigated and compared with that recorded for the commercial Ni-RuO2 De Nora's (DN) cathode. The morphology and chemical compositions of all NiSn samples were investigated by SEM and EDS techniques before and after the SLT. HER during the SLT has also been monitored by EIS technique. The chemical compositions of surfaces of all NiSn alloy samples, as well as EIS results, were found to depend on the number of cycles performed during the SLT. The decrease of their catalytic activity for the HER in 32 wt.% NaOH at 90 degrees C with increasing the number of cycles (about 20-25 mV after 25 cycles) was practically identical to that for DN cathode, while NiSn samples deposited at -30 mA cm(-2), -60 mA cm(-2) and -100 mA cm(-2) possessed lower overpotential for the HER before and after SLT in comparison with that for the DN cathode. It is confirmed by the SEM-EDS and EIS analysis of the NiSn samples that the minor loss of the catalytic activity for the HER is the consequence of the change of chemical composition of NiSn coatings and decrease of the active surface area. This decrease is ascribed to partially eroded NiSn coatings due to oxygen evolution during the SLT.",

AB  - The aim of this work was to investigate the possibility of preparation of the composite Cr-MoO2 coatings onto steel and titanium substrates as cathode materials with high selective properties which imply the suppression of hypochlorite reduction as a side reaction during hypochlorite commercial production. The electrodes were prepared by simultaneous deposition of chromium and suspended MoO2 particles on titanium substrate from acid chromium (VI) bath. The current efficiency for electrodeposition of the composite coatings did not vary significantly with the concentration of suspended MoO2 particles. The content of molybdenum in the deposits was relatively low (0.2-1.5 at.%) and increased with increasing the concentration of suspended MoO2 particles in the bath, in the range from 0 to 10 g dm(-3). With further increase in the concentration of MoO2, the content of molybdenum in the coating varied insignificantly. X-ray photoelectron spectroscopy-XPS and EDS analysis were applied to analyze elemental composition and chemical bonding of elements on the surface and in the sub-surface region of obtained coatings. When the concentration of MoO2 particles in the bath was raised above 5 g dm(-3), the appearance of the coating changed from the typical pure chromium deposit to needle-like deposit with the appearance of black inclusions on the surface. XPS analysis and corresponding Cr 2p spectra showed the presence of chromium oxide, probably Cr2O3 with Cr(3+) valence state on the surface and in the sub-surface region of Cr-MoO2 coatings. Investigation of the current efficiency for the hydrogen evolution reaction (HER) on Cr-MoO2 cathodes showed that it increased with the increase of the content of MoO2 particles in the coating, exceeding the value of 97% in the solution with the hypochlorite concentration of 0.21 mol dm(-3). Under the same conditions, the current efficiency for the HER on Ti and Ti/Cr cathodes is very low (approximate to 20%), and corresponding polarization curves confirmed the fact that the side reaction of hypochlorite reduction takes place in the diffusion-controlled regime on these electrodes. The high selectivity of Cr-MoO2 coating is probably caused by the presence of chromium oxide (hydroxide) formed at the surface of the coating during co-deposition of Cr and MoO2 particles, which prevents hypochlorite reduction on the cathode during the HER.

AB  - The hydrogen evolution reaction (HER) was studied on Ni, Ni-Ebonex and Ni-(Ebonex-Ru) coatings in 1 mol dm(-3) NaOH solution at 25 degrees C. The composite coatings were electro-deposited from a nickel Watts-type bath containing suspended Ebonex (chemical composition mainly Ti4O7) or Ebonex-supported Ru(10 wt.%) particles (0-10 g dm(-3)) onto Ni mesh substrate. The electrodes were investigated by cyclic voltammetry (CV), transmission electron microscopy (TEM) and scanning electron microscopy (SEM) in combination with energy dispersive X-ray spectroscopy (EDS) and electron energy loss spectroscopy (EELS), electrochemical impedance spectroscopy (EIS) and polarization measurements. These investigations showed that the roughness factor of the Ni-(Ebonex-Ru) and the Ni-Ebonex coating was 29 and 6 times higher than that of a pure Ni coating, respectively. In the whole potential range of the HER only one Tafel slope of about -120 mV was present at the polarization curves of Ni and Ni-Ebonex electrodes, with increased activity of the latter being attributed only to the increase of the electrochemically active surface area. The Ni(Ebonex-Ru) electrodes exhibited the highest intrinsic catalytic activity with two Tafel slopes, indicating also that the HER takes place exclusively. on Ru active sites.

AB  - The electrodeposition of Ni-MoO2 composite coatings is a specific process taking place under defined hydrodynamic conditions. In this work the influence of hydrodynamics, current density, and MoO2 concentration on the electrodeposition of Ni-MoO2 coatings from a suspension of MoO2 particles in a Watt’s type bath were investigated by comparison of their polarization characteristics for the hydrogen evolution reaction (HER) in 1 M NaOH at room temperature. It was shown that electrolyte and air flow rates influence the process of coating electrodeposition at low concentrations of MoO2. With increases in MoO2 concentration the current density became the main parameter influencing the coatings’ properties. The best coating, with the lowest over-voltage for the HER, was obtained from the suspension containing 3 g dm-3 of MoO2 particles. The over-voltage of this coating was 57 mV lower for the HER at j = –0.3 A cm-2 (the current density used in industrial applications) than that for the commercial De Nora’s Ni + RuO2 electrode.

AB  - In this work, the effect of aging of the electrolyte in the electrodeposition of Ni MoO2 composite coatings on their morphology (scanning electron microscopy), chemical composition (energy-dispersive X-ray spectroscopy), polarization characteristics and "service life", tested for the hydrogen evolution reaction (HER) in 32 mass % NaOH at 90 degrees C, was investigated. Polarization characteristics and results of the "service life" test of Ni MoO2 composite coatings obtained after different aging periods of the electrolyte for deposition (suspension of MoO2 powder particles in a solution containing 2 M NH4Cl + + 0.2 M NiCl2) were compared with that recorded for the commercial De Nora's Ni+RuO2 cathode coating (DN). It was shown that aging of the electrolyte did not influence the morphology and chemical composition of Ni MoO2 composite coatings electrodeposited under conditions simulating their industrial production, while the polarization characteristics for the HER were influenced. The best coating, obtained after 180 days of electrolyte aging, showed a completely different (layered) structure of the deposit and significantly better performance than the commercial DN electrode during the "service life" test.

AB  - In this work the hydrogen evolution reaction (HER) at Ni-Sn alloy coatings, deposited onto Ni 40 mesh at different current densities from the bath containing 0.1 mol dm(-3) SnCl2 + 0.3 mol dm(-3) NiCl2 in the pyrophosphate-glycine solutions, was investigated by polarization and EIS measurements. The morphology and chemical compositions of all samples were investigated by the SEM and EDS techniques. It was shown that their morphologies and chemical compositions depend on the deposition current density. The increase of their catalytic activity for the HER in 6 mol dm(-3) KOH and in 1 mol dm(-3) NaOH with increasing the deposition current density was shown to be the consequence of the change of both: their chemical composition and morphology.

AB  - In this work the electrodeposition of Ni, Sn and Ni-Sn alloy from the solution containing pyrophosphate and/or glycine has been investigated by cyclic voltammmetry (CV), potentiostatic pulse and polarization curve measurements on two substrates, Ni and GC. It has been shown that the process of Sn electrodeposition in pure pyrophosphate solution commences at the potential of about -0.90 V on both substrates being characterized by the formation of isolated 3D crystals and their further growth by the reduction of [Sn(Pyr)(2)](6-) complex. On the GC surface Sn 3D crystals remain isolated, following 3D nucleation and growth mechanism which does not fit any of the theoretically predicted models. Ni-Sn alloy deposition in the solution containing both cations (Sn2+, Ni2+) and both anions (pyrophosphate and glycine) occurs by the same growth mechanism as pure Sn deposition by simultaneous reduction of [Sn(Pyr)(2)](6-), [Ni(Pyr)(2)](6-) and/or [Ni(Pyr)(3)](-) complexes at pH 8.0. Depending on the current density/potential of the Ni-Sn alloy coating deposition onto Ni electrode the composition of the flat and compact coatings varies in the range from 66 to 50 atom% Ni, i.e. 34 to 50 atom% Sn.

abstract = "In this work the electrodeposition of Ni, Sn and Ni-Sn alloy from the solution containing pyrophosphate and/or glycine has been investigated by cyclic voltammmetry (CV), potentiostatic pulse and polarization curve measurements on two substrates, Ni and GC. It has been shown that the process of Sn electrodeposition in pure pyrophosphate solution commences at the potential of about -0.90 V on both substrates being characterized by the formation of isolated 3D crystals and their further growth by the reduction of [Sn(Pyr)(2)](6-) complex. On the GC surface Sn 3D crystals remain isolated, following 3D nucleation and growth mechanism which does not fit any of the theoretically predicted models. Ni-Sn alloy deposition in the solution containing both cations (Sn2+, Ni2+) and both anions (pyrophosphate and glycine) occurs by the same growth mechanism as pure Sn deposition by simultaneous reduction of [Sn(Pyr)(2)](6-), [Ni(Pyr)(2)](6-) and/or [Ni(Pyr)(3)](-) complexes at pH 8.0. Depending on the current density/potential of the Ni-Sn alloy coating deposition onto Ni electrode the composition of the flat and compact coatings varies in the range from 66 to 50 atom% Ni, i.e. 34 to 50 atom% Sn.",

AB  - MoO3 particles were co-deposited with Ni onto smooth or rough Ni supports from modified Watt baths of different compositions. Morphology and composition of the electrodeposits were characterized by means of cyclic voltammetry, X-ray diffraction analysis, scanning electron microscopy, transmission electron microscopy and energy dispersive X-ray spectroscopy. The electrocatalytic activity of the composite catalysts for H-2 evolution in alkaline solutions was determined by quasi-stationary polarization curves. Activity increases with MoOx content in the Ni deposit up to a limiting value. The composite Ni-MoOx catalysts exhibited high catalytic activity, similar to that of a commercial Ni-RuO2 catalyst. Stability tests showed that the Ni-MoOx co-deposits were stable under constant current conditions and exhibited excellent tolerance to repeated short-circuiting.

AB  - In this work the hydrogen evolution reaction (HER) onto Ni-Sn alloy coatings deposited at different current densities from the bath containing 0.1 M Sn2+ and 0.1 M Ni2+ ions in the pyrophosphate-glycine solution, was investigated by polarization curves and electrochemical impedance spectroscopy (EIS) measurements. Their morphology and chemical composition were investigated by scanning electron microscopy equipped with an energy-dispersive X-ray spectroscopy (SEM-EDS), while the phase composition was investigated by X-ray powder diffraction (XRPD). It was shown that their chemical composition, phase composition and morphology depend on the deposition current density. In deposited samples all detected phases, face centered cubic (fcc) Ni, close packed (hcp) hexagonal Ni3Sn, hexagonal Ni(1-i-x)Sn (0  lt  x  lt  0.5) which adopts NiAs structure type and monoclinic Ni3Sn4 (CoSn structure type), were of low crystallinity. The increase of the Ni-Sn alloy coatings catalytic activity for HER in 6 M KOH with increasing the deposition current density was shown to be the consequence of the change of all three parameters: chemical composition, phase composition and morphology, with the effect of morphology being the most pronounced.

AB  - As a result of research on the non-noble metal-based composite electrocatalysts for the hydrogen evolution reaction (HER), the Ni-MoO2 composite coating was produced by electrodeposition from an NH4Cl and NiCl2 containing solution with suspended MoO2 powder particles, exhibiting almost the identical activity for the HER as the commercial cathode in conditions of industrial application and satisfactory mechanical stability. In this work, investigations were extended to the kinetics and mechanism of the HER on the Ni-MoO2 electrode in 8 M NaOH solution at 30 degrees C. The steady-state polarization curve for the HER was characterized by only one Tafel slope of -122 mV/dec. Kinetic parameters for the HER, as well as a contribution of surface roughness to the catalytic activity, were evaluated using an electrochemical impedance spectroscopy (EIS) technique. On the basis of the presented theoretical model for the faradaic impedance of the HER, the rate constants of the individual steps were determined by simulating both polarization and EIS experimental data. It was found that the reaction equally proceeds via the Volmer-Heyrovsky and Volmer-Tafel routes at lower overpotentials, while at higher overpotentials the Volmer-Heyrovsky pathway dominates the process with the Heyrovsky step being the rate determining step (rds). A comparison of intrinsic activities of the Ni-MoO2 composite and a flat Ni electrode proved that the combination of Ni and MoO2 produced a true catalytic effect for the HER.

AB  - In this work polarization characteristics and "service life" test of the non-noble metal composite coatings Ni-MoOx and Ni-MoO2 for hydrogen evolution reaction (HER) in 32 wt.% NaOH at 90 degrees C were investigated and compared with that recorded for De Nora's commercial Ni + RuO2 cathode coating (DN). It was shown that under conditions of industrial application in the "zero-gap" membrane cells the lowest over-voltage for HER has been recorded for the Ni-MoO2 coating. At the same time the "service life" test was performed on all three electrodes in the same solution. This test was based on monitoring the current density response before and after repetitive cycling of these electrodes with 50 mV s(-1) in the potential range from hydrogen (-1.25 V vs. SCE) to oxygen (0.50 V vs. SCE) evolution. It was shown that the activity for all electrodes at the end of a "service life" test dropped to approximately 54% of the initial value, being comparable with the results obtained for Pt-based cathodes. The SEM-EDS analysis of the electrodes after the "service life" test showed that the Ni-MoO2 is much more stable than the Ni-MoOx composite coating and could be promising replacement for the commercial cathode.

AB  - The electrochemical deposition of the Fe-Ni alloy powders from citrate-sulfate containing electrolytes of different Ni/Fe ions concentration ratios at pH 4.5 was examined by the polarization measurements. All polarization curves have a similar shape and are characterized by the presence of two inflection points. The first inflection point reflects the beginning of alloy deposition, while the second one (˜) corresponds to the moment when the cathode reaction becomes determined by the rate of hydrogen bubbles formation. The potentials of Fe-Ni alloys deposition at all investigated Ni/Fe ratios are more positive than those for pure metal powders deposition. As the Ni/Fe ratio decreases, the polarization curves are placed at slightly more positive potentials. The morphology of electrodeposited powder particles was investigated using scanning electron microscopy (SEM). A common characteristic of all Fe-Ni alloy powders is the presence of cone shaped cavities. Powder particles electrodeposited at the ratio Ni/Fe = 9/1 are mainly consisted of nodules of either very flat surface or rough surface, with well defined crystals detected only on a few particles. With the decrease of the Ni/Fe ratio, the presence of well defined crystals on the nodule surface becomes more pronounced. In the powder with the highest amount of Fe (Ni/Fe = 1/3), the whole surface of all particles is covered with crystals of different shapes.

AB  - In this work the procedure of the deposition of composite Ni-MoO2 coatings onto Ni mesh from the nickel chloride-ammonium chloride electrolyte containing suspended MoO2 powder particles, under simulated industrial deposition conditions for commercial cathodes, has been presented. The morphology of the obtained coatings was investigated by SEM, the composition by EDS and the phase composition by XRD techniques. The polarization characteristics for hydrogen evolution on the obtained Ni-MoO2 coatings were investigated in the 32 wt.% NaOH at 90 degrees C and compared with the one recorded for the commercial De Nora's coating (DN). It was shown that the best Ni-MoO2 coating posses identical polarization characteristics as the commercial one. By the cross section and XRD analysis of deposited samples it was confirmed that MoO2 powder particles were occluded by the Ni deposit, being uniformly distributed in the deposit.

AB  - In this work the Ni-MoOx coatings have been prepared and characterized in view of their possible application as electrocatalysts for hydrogen evolution reaction (HER) in alkaline solution. The procedure of deposition of Ni-MoO3 coatings from the Watt's type bath containing MoO3 powder particles onto Ni mesh, under the conditions of simulated industrial deposition conditions for commercial cathodes, has been presented. The morphology of the obtained coatings was investigated by SEM, the composition by EDS and the phase composition by XRD techniques. The polarization characteristics for hydrogen evolution on the obtained Ni-MoO3 coatings were investigated in the 32 wt.% NaOH at 90 degrees C and compared with the one recorded for the commercial De Nora's coating (DN). It was shown that the best Ni-MoOx coating exhibits almost identical polarization characteristics as the commercial one. By the cross section and XRD analysis of deposited samples it was confirmed that MoO3 powder particles were not occluded by the Ni deposit and that molybdenum species were deposited from the molybdate ions formed by dissolution of MoO3, following the mechanism of induced co-deposition. The reaction mechanism for MoO3 phase deposition has also been proposed.

AB  - During electrodeposition of Ag-Cd alloy coatings phenomena of self-organization and formation of spatio-temporal structures can be observed. The difficulties in the determination of the local phase composition in the observed structures are mostly connected with the strong heterogeneity of the coatings consisting of several alloy phases. The results obtained with electrochemical techniques, such as anodic linear sweep voltammetry (ALSV) are compared with results obtained by X-ray analysis and SEM. In the proposed electrolyte for dissolution of Ag-Cd alloy coatings (12 M LiCl + 0.1 M HCl) the dissolution peaks of the pure metals, Ag and Cd, have a potential difference of about 700 mV. The peaks, corresponding to the alloy phases, are situated between the dissolution potentials of Ag and Cd, their height depending on the deposition current density, i.e. on the percentage content of the alloy. Different phases (Ag. Ag3Cd, AgCd, AgCd3 and pure Cd) are observed in the coatings deposited at different cathodic potentials. A good correlation between the XRD spectra of the Ag-Cd alloy coatings and the ALSV data obtained during their dissolution is established.
