“…Recently, there has been a need to develop methods for obtaining new generations of solar cells used as anode materials in the form of thin films and nanostructures based on cadmium. Analysis of the literature revealed a number of works devoted to the electrolytic reduction of cadmium and the preparation of its chalcogenides from various electrolytes [1,2,[8][9][10][11][12][13].…”

“…Electrodeposition of cadmium from water-methylpyrrolidone electrolytes with a predominant content of the water phase was studied using diagnostic criteria commonly used in chronopotentiometry and chronovoltammetry [2]. The obtained chronopotentiograms had a single wave of cadmium ion reduction at all studied current densities and concentrations of the non-aqueous component.…”

The work is devoted to the study of the process of cathodic reduction of Cd ions from anhydrous ethylene glycol electrolyte. The mechanism of the process of cadmium reduction was studied by taking linear and cyclic potentiodynamic polarization curves. The influence of cadmium chloride concentration, potential sweep rate and temperature on the process of electrochemical deposition of cadmium ions was studied. With an increase in the concentration of cadmium in the electrolyte, the rate of its release at the cathode increases. Precipitates of good quality are obtained at current densities of 25 mA/sm2. It has been established that the cadmium deposition potential almost does not change with increasing potential sweep rate. The dependence of cadmium electrodeposition from ethylene glycol electrolyte on temperature was studied, which made it possible to establish the optimal deposition temperature, which was 363–373 K, and to conclude that the deposition process is controlled by electrochemical polarization. The diffusion coefficient of cadmium ions to the cathode surface has been calculated

“…Изучение процессов адсорбции на границе раздела катод-электролит [21] и комплексообразования в сульфатных электролитах кадмирования [22] позволило выявить отчетливую зависимость кинетических параметров процесса, состава и триботехнических свойств металлорганического покрытия от концентрации N-метилпирролидона и производного анилина [21]. Химические превращения циклических органических соединений могут происходить как с раскрытием цикла, так и без него.…”

Установлено, что в сульфатных электролитах кадмирования кинетика катодного процесса, микроструктура и свойства покрытий являются функцией природы и концентрации органических добавок, в качестве которых изучены ε-капролактам (КЛ), тетрагидрофуран (ТГФ) и пропиленкарбонат (ПК). Изменение состава жидкой фазы и введение в раствор циклического лактама, меняя условия сольватации, заметно сказываются на адсорбционных и координирующих свойствах компонентов электролита и, как следствие, на характере катодных процессов. Сравнением 3d-сканов поверхностей сформированных покрытий подтверждено образование металлполимерного покрытия на основе кадмия в присутствии КЛ. Расчет параметров решетки кадмия и кадмийорганического покрытия, содержащего КЛ, показал уменьшение среднего размера и объема зерен осадка.
