“…The complexity of electrochemical processes involving molybdenum compounds is manifested in the existence of a large number of intermediate oxidation states, as well as in the significant adsorbability of molybdenum compounds on electrodes. Despite the large amount of experimental material, the kinetics of electrode reactions in the presence of molybdenum compounds is still uncertain [16][17][18][19][20]. In principle, the adsorption of these compounds is possible in a wide range of potentials, which certainly, affects the kinetics of reactions occurring on electrodes.…”

Based on the study of current-voltage dependencies during electroreduction of molybdenum ions from sulfate electrolytes on Pt electrode, the conditions of deposition of Mo-nanocoatings were established. The influence of various factors such as temperature, content of components in the electrolyte, current density, acidity of solutions, etc., on the composition and quality of coatings was studied. It was found that, with an increase in the concentration of molybdenum and current density, the molybdenum content increases and the quality of coatings improves. Based on the determination of the nature of the cathodic polarization, it was found that the process of electrodeposition of molybdenum from sulfate electrolyte is mainly accompanied by chemical polarization. According to the experimental data, the following electrolyte composition (mol/l) is recommended for obtaining molybdenum nanocoatings: 2.0·10-2– 1.5·10-3 Na2MoО4 +2.0 H2SO4; pH=0.4; EV=0,005 Vs-1; t=750C, electrod – Pt

The electrochemical reduction of iron (III) ions into zero-valent iron from a solution of ethylene glycol was accomplished. The kinetics and mechanism of the electroreduction process were investigated by cyclic and linear polarization techniques. The influence of temperature, potential sweep rate, and concentration of iron (III) ions on the electroreduction process was also studied. The observed values of effective activation energy revealed that the investigated electroreduction process is accompanied by mixed kinetics control. Moreover, the results of SEM and X-ray diffraction analysis confirmed the deposition of thin Fe films under the optimized conditions.

Antimony selenide (Sb2Se3), is an excellent photovoltaic absorber due to its high absorption coefﬁcient (> 105 cm–1) at the visible region and 1.17 eV band gap. In recent years, the power conversion efficiency of Sb2Se3 thin film solar cells has gradually enhanced. Therefore, given the great interest in this material, this work is devoted to the study of a mathematical model for the optimization of the preparation of thin Sb–Se films by the electrochemical method. The study was conducted by potentiodynamic, potentiostatic and galvanostatic methods carried out under different conditions at Pt, Cu and Ni elec-trodes. The kinetics and mechanism of the electroreduction of antimony and selenite ions in the tartaric acid were studied separately for the electrochemical deposition. On the basis of cyclic polarization, X-ray phase and SEM-EDX analyses, it is found that Sb–Se thin films are deposited on Pt and Ni electrodes, but not on Cu electrode. The mathematical calculations were performed in the OptimME software package using specially developed software for this process. By studying the effects of various factors (concentration of the initial components, temperature, current density, etc.), the optimal electrolysis mode and electrolyte composition for the co-deposition process were selected. Based on these results, Student and Fisher criteria were assigned for future purposes and regression coefficients were estimated. The obtained regression equation determines the electrolyte content and the electrolysis conditions, which allows precipitating the Sb–Se alloy containing the required amount of Sb. Calculations and experimental results show that the error of the regression equation for obtaining the Sb–Se alloy is =6.4%.
