Sereduyk V. Effect of the nature of ligands on the electrochemical reactions with the participation of Сhromium cation complexes

Object of the research on the detailed investigation of electrodeposition of chromium process. Research objective is to determine the possible ways of reaction and factors influencing the kinetics of the rate determining step. Methods of the research are quantum-chemical modeling using DFT-methods, voltammetry with linear potential scan and cyclic voltammetry. The nature of chromium electrodeposition rate determining step has been established. It has been shown that the most endothermic process is removing of the three water molecules from intermediates chromium(II). It has been shown that the highest value of kinetic current occured in the case of chromium disubstituted aqua complexes electroreduction. The of use: electrochemistry and electrochemical technologics.
