AB  - The effects of common precursors used in the synthesis of CeO2 nanopowders were investigated, and the structural and spectral properties of the resulting products were compared. Two cerium (III) salts, i.e., Ce(NO3)(3)center dot 6H(2)O and CeCl3 center dot 7H(2)O, and two cerium (IV) salts, i.e., Ce (SO4)(2)center dot 4H(2)O and (NH4)(2)Ce(NO3)(6) were applied. The proposed procedures for the CeO2 preparations were realizdd using the same hydrothermal treatment conditions. The products were characterized using X-ray powder diffraction (XRD) and thermogravimetric (TG) analysis, and the morphology was determined using scanning (SEM) and transmission electron microscopy (TEM). The spectral properties of the obtained nanopowders were characterized by FT-IR, Raman scattering and UV-vis spectroscopy. The results revealed the influence of the precursors on the crystallinity, crystallite size, band gap energy, morphology and purity of the synthesized samples.

AB  - In this work, zinc oxide powders were obtained by two different techniques: hydro- and solvothermal synthesis starting from Zn(NO3)(2) and Zn(CH3COO)(2), respectively. The influence of synthetic procedure on the structural, microstructural, thermal and photocatalytic properties of the prepared ZnO powders was investigated. Both ZnO samples were further annealed under moderate conditions (300 degrees C) to avoid grain growth and to remove traces of impurities. In all four cases, single-phase hexagonal ZnO was confirmed by X-ray powder diffraction. The morphologies of prepared ZnO powders were different and they varied from rounded nanograins to microrods. All prepared samples showed higher photocatalytic efficiency in the degradation of the textile azo dye Reactive Orange 16 (RO16) than commercial ZnO. In addition, the non-annealed samples had better photocatalytic properties than the commercial Degussa P25 TiO2 powder.

AB  - In this work we have explored different ways for synthesis of nanosized CeO2.
Four different salts of cerium were used as starting materials for the synthesis as the
precursors: two salts of cerium (III): Ce(NO3)3·6H2O and CeCl3·7H2O, and two salts
of cerium (IV): Ce(SO4)2·4H2O and (NH4)2Ce(NO3)6. The precipitated precursors
were washed and then subjected to hydrothermal treatment at 200 ºC during 18 h. In
some cases hydrothermally prepared samples were annealed at higher temperature to
obtain phase-pure samples. The phase identification of the samples and analysis
were carried out by X-ray diffraction, FTIR spectroscopy, and TG/DSC analysis.

AB  - Anatase is a well-known photocatalyst mostly used to degrade or transform organic and inorganic water pollutants. Its photocatalytical properties depend on surface area, availability of active sites, pore sizes, number and nature of trapped sites, as well as on adsorption/desorption characteristics. In order to reach the highest performance, the main challenge is to find new methods for anatase preparation or modification to achieve a balance between mentioned properties.
In this work, hydrothermal treatments of anatase were carried out at 120, 150 and 180 °C during 6, 12 and 18 h in NaOH solution (c = 3 mol dm–3). The samples were characterized by X-ray powder diffraction (XRPD), scanning and transmission electron microscopy (SEM and TEM). The photocatalytic activity and efficiency of the samples were tested on Reactive Orange 16 (RO16) dye and compared to commercial P-25 powder (Degussa). The powders are coded as UT_t, where T is temperature of the treatment and t is duration of the treatment.
XRPD analysis showed that phase composition of the samples remains the same and confirms absence of the reaction between anatase and NaOH, which would result in formation of a sodium-titanate. Nanoparticles of modified anatase form soft agglomerates that differ in size 1 – 5 m, as SEM analysis showed. Size of modified nanoparticles is about 5 nm what is observed by TEM. It is also found that formation of anatase nanotubes, with lengths 100 – 250 nm, is started. The adsorption power of U120_18 and U150_6 samples is twice as much as adsorption power of P-25 powder. The samples U150_12 and U180_6 have adsorption power very similar to P-25, while all other samples show much lower adsorption power. The photocatalytic activity of all modified samples is lower than phtocatalytic activity of P-25, but because of higher adsorption power the overall efficiency of RO16 degradation in water with U120_18 and U150_6 samples is comparable to the efficiency of P-25 powder.

AB  - Nedavno je otkriveno da litijum-tereftalat (Li2tpht) pokazuje veću termičku stabilnost u poređenju sa konvencionalnim anodnim materijalima u litijum-jonskim baterijama [1]. U ovom radu upoređena su dva postupka sinteze pomenutog jedinjenja. Prvi postupak opisan je od strane Kaduka [2], dok drugi pristup predstavlja nov postupak. Prema Kaduku, Li2tpht dobijen je taloženjem iz vodene suspenzije koji sadrži Li2O i tereftalnu kiselinu (H2tpht) u molskom odnosu 1:1. Novi postupak zasnovan je na jednostavnom mlevenju reaktanata, Li2CO3 i H2tpht, u ahatnom avanu. Oba uzorka okarakterisana su pomoću FTIR spektrokopije, TG/DSC i XRD analize. Dobijeni rezultati su međusobno upoređeni i diskutovani.

AB  - Recently, it has been discovered that dilithium terephthalate (Li2tpht) shows enhanced thermal stability over conventional anode materials for Li-ion batteries [1]. This investigation compares two ways of synthesis of the mentioned compound. The first one was described by Kaduk [2] and the other approach presents a new procedure. According to Kaduk, Li2tpht is obtained by precipitation from an aqueous suspension containing Li2O and terephthalic acid (H2tpht) in a molar ratio 1:1. The new method is based on a simple grinding of Li2CO3 and H2tpht in an agate mortar. Both samples were characterized by FTIR spectroscopy, TG/DSC and XRD analysis. The obtained results are compared and discussed.

abstract = "Nedavno je otkriveno da litijum-tereftalat (Li2tpht) pokazuje veću termičku stabilnost u poređenju sa konvencionalnim anodnim materijalima u litijum-jonskim baterijama [1]. U ovom radu upoređena su dva postupka sinteze pomenutog jedinjenja. Prvi postupak opisan je od strane Kaduka [2], dok drugi pristup predstavlja nov postupak. Prema Kaduku, Li2tpht dobijen je taloženjem iz vodene suspenzije koji sadrži Li2O i tereftalnu kiselinu (H2tpht) u molskom odnosu 1:1. Novi postupak zasnovan je na jednostavnom mlevenju reaktanata, Li2CO3 i H2tpht, u ahatnom avanu. Oba uzorka okarakterisana su pomoću FTIR spektrokopije, TG/DSC i XRD analize. Dobijeni rezultati su međusobno upoređeni i diskutovani.

[2] J. A. Kaduk, Acta Crystallogr. B56, 474-485 (2000)., Recently, it has been discovered that dilithium terephthalate (Li2tpht) shows enhanced thermal stability over conventional anode materials for Li-ion batteries [1]. This investigation compares two ways of synthesis of the mentioned compound. The first one was described by Kaduk [2] and the other approach presents a new procedure. According to Kaduk, Li2tpht is obtained by precipitation from an aqueous suspension containing Li2O and terephthalic acid (H2tpht) in a molar ratio 1:1. The new method is based on a simple grinding of Li2CO3 and H2tpht in an agate mortar. Both samples were characterized by FTIR spectroscopy, TG/DSC and XRD analysis. The obtained results are compared and discussed.",

AB  - Extra phase-pure Li4Ti5O12 spinel with particle sizes less than 500 nm was synthesized by solid state reaction of mechanochemicaly activated mixture of nano anatase and Li2CO3 for a very short annealing time, 4 h at 800 degrees C. Structural and microstructural properties, the mechanism of solid state reaction between anatase and Li2CO3 as well as thermal stability of prepared spinel were investigated using XRPD, SEM and TG/DSC analysis. The mechanism of reaction implies decomposition of Li2CO3 below 250 degrees C, formation of monoclinic Li2TiO3 as intermediate product between 400 and 600 degrees C and its transformation to Li4Ti5O12 between 600-800 degrees C. The spinel structure is stable up to 1000 degrees C when it is decomposed due to Li2O evaporation.
