“…The potential dependence of each of these steps was examined in detail somewhat later [28], and the large variation in the observed transfer coefficient explained. The ion transfer mechanism of Baranski and Fawcett differs significantly from the electron transfer mechanism proposed earlier by Losev [29] which involves formation of atoms and intermediate ions such as Mg + in the double layer.…”

Developments in the treatment of double layer effects in electrode kinetics are outlined. These include discreteness-of-charge effects in the presence of specific adsorption, solvent effects in electron transfer reactions, and effects related to the distribution of charge in polyatomic reactants. The importance of studies at single crystal electrodes is emphasized, and the development of a single crystal ultramicroelectrode described. Finally, a method of improving the estimate of the diffuse layer potential drop on the basis of Monte Carlo simulations is presented.

“…Для встановлення стадії з уповільненим перенесенням електрона використовують низку критеріїв, які переважно ґрунтуються на порівняння тафелівських нахилів відповідних катодних і анодних ділянок поляризаційних залежностей [20]. На рис.…”

“…Втім, застосування відомих критеріїв стадійності наштовхується на труднощі, оскільки сума уявних коефіцієнтів перенесення для катодної та анодної реакцій повинна дорівнювати загальній кількості електронів, що беруть участь у процесі (в даному випадку, очевидно, це два електрони) [20], що явно не виконується у даному випадку.…”

Features of kinetics and mechanism of Ni(II) ion electroreduction in the course of electrodeposition of nickel and Ni–TiO2 composites from a deep eutectic solvent

Kinetic characteristics of the nickel ion discharge were investigated for the first time from electrolytes based on a new kind of ionic liquids, deep eutectic solvents. The study was carried out using electrolytes based on ethaline, a liquid eutectic mixture of choline chloride choline and ethylene glycol in a molar ratio of 1:2, respectively, in which 1 М NiCl2·6H2O was dissolved. It was shown that the apparent transfer coefficients for electrochemical process in the system Ni(II)/Ni(0) in ethaline were equal to α=0.309 and β=0.255 for anodic and cathodic reactions, respec-tively. It is difficult to interpret these values in the framework of known criteria of consecutive electrochemical pro-cesses. In order to explain this phenomenon, a theoretical conception was used, that was earlier developed by Gileadi. According to that conception, electric charge during metal electrodeposition is transferred through the electrode interface by metal ions, but not by electrons. Therefore, potential barrier in a double electrical layer be-came very asymmetric (i.e. the apparent transfer coefficient deviates from 0.5). It was found that the introduction of TiO2 particles (0–10 g dm–3) into the electrolyte based on ethaline results in declaration of electrochemical re-duction of nickel (II) ions due to a partial blocking of the electrode surface by adsorbed colloidal particles of titani-um dioxide.
