AB  - The oxygen reduction reaction was investigated at 10 monolayers (MLs) of Pt electrodeposited on (Nb–Ti)2AlC substrate. Following the discussion of detailed kinetics and electrodeposition optimisation in the authors’ previous paper, the focus of this research was on stability testing. Previously performed optimisation results showed the best activity shown by 10 monolayers of Pt. Catalyst characterisation was performed by scanning electron microscopy, X-ray photoelectron spectroscopy and transmission electron microscopy. SEM, EDS and XPS analysis showed that the surface was covered with a homogeneous layer of Pt. TEM analysis of a cross-section confirmed the presence of Pt layer of thickness ∼3.5 nm, corresponding to the 10 MLs of Pt. Although the mass activity for the ORR at 0.8 V vs. RHE of 37.4 A g−1 was comparable with the best one for the Pt/C benchmark, US Department of Energy Protocols revealed excellent catalyst stability – the loss of electrochemically active surface area (EASA) was found to be only 9.3%.

AB  - The hydrogen evolution reaction (HER) was investigated in 0.5 M H2SO4 at thin iridium layers electrodeposited on Ti2AlC substrate. Five samples, varying in thickness from 4.5 nm to 255 nm, were electrodeposited from the solution containing K3IrCl6 + Na2SO4. Scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS) were applied for morphology and chemical composition analysis. Metallic iridium was detected by X-ray photoelectron spectroscopy (XPS). The HER was investigated by polarization and electrochemical impedance spectroscopy (EIS) measurements. Polarization curves were characterized with the low Tafel slopes -18 mV dec(-1), while at higher current densities increased up to -56 mV dec(-1). The overpotential at j = -0.1 A cm(-2) was-45 mV, while at j = -0.01 A cm(-2) varied from 25.1 mV to 36.1 mV. These novel catalysts exhibited excellent activity, especially under industrial conditions of hydrogen production (j = -0.3 A cm(-2)) the determined overpotentials were between 66 and 69 mV only.
