Sažetak
Based on the study of volt-ampere dependencies during electroreduction of rhenium (VII), tellurium (IV) and copper (II) ions from hydrochloric acid electrolyte on Pt electrode, the conditions of deposition of nano-coatings of ternary Re-Te-Cu alloy were determined. The influence of various factors such as amounts of individual components and total concentrations of components in the electrolyte solution, temperature, concentration of hydrochloric acid, etc., on the composition and quality of coatings was studied. It was established that with the increase of rhenium concentration in the electrolyte, as well as increase of temperature, the rhenium content in deposits increased. The morphology of films deposited on platinum substrate was studied using scanning electron microscopy. Based on the experimental data, the following electrolyte composition (mol/l) is recommended for obtaining the semiconductor Re-Te-Cu alloy containing 40-50 wt.% Re: (6.9·10-4-6.9·10-3) KReO4 + (9·10-4-1.8·10-2) TeO2 + (6·10-4-1.2·10-2) CuCl2·2H2O +2 HCl, T = 75 °C.
