Redox reactions of dissolved substances on amalgamated platinum electrode modified with adsorbed porphyrinRussian Journal of Electrochemistry - Tập 45 Số 10 - Trang 1206-1210 - 2009
Khanova, L. A.
In order to develop the electrodes convenient for investigating the high-rate redox reactions not distorted by a reagent adsorption, the modification of amalgamated Pt electrodes with a monolayer of irreversibly adsorbed porphyrin is studied. A specific feature of applied procedure is that the adsorption was performed at a controlled electrode potential from the aqueous solution, in which porphyri...... hiện toàn bộ
Diffusion of acid and alkaline salt solutions through the Nernst diffusion layerRussian Journal of Electrochemistry - Tập 45 - Trang 1193-1197 - 2009
N. P. Gnusin
The behavior of diffusion layer under the conditions of salt transfer with excess of acid or alkali, involving the hydrogen and hydroxyl ions, is studied. The transfer is affected by the applying of current. The method of investigation was mathematical simulation based on the solving of boundary problems by using the Nernst-Planck equation with regard to the corresponding conditions of the transfe...... hiện toàn bộ
Interaction between Thallium and the Au(111) Surface. Quantum-Chemical AnalysisRussian Journal of Electrochemistry - Tập 54 - Trang 912-921 - 2019
N. A. Rogozhnikov
The interaction between thallium atoms and the Au(111) surface is studied using the cluster metal surface model and the density functional method. An adsorbed thallium atom forms a strong chemical bond with surface gold atoms. The adsorption energy barely depends on the location of the thallium atom. The electron density is appreciably displaced from thallium to gold in the process of adsorption. ...... hiện toàn bộ
Electrochemical machining of metals: Fundamentals of electrochemical shapingRussian Journal of Electrochemistry - Tập 40 - Trang 1230-1265 - 2004
A. D. Davydov, V. M. Volgin, V. V. Lyubimov
Basic problems of metal electrochemical shaping theory are considered. Exact and approxi1mate (quasi-steady-state, locally one-dimensional) methods for solving direct and inverse problems are analyzed. Experimental methods for improving the electrochemical shaping accuracy are considered.
Copper UPD on Selenium-Modified Polycrystalline Pt ElectrodeRussian Journal of Electrochemistry - Tập 38 - Trang 488-495 - 2002
A. Steponavicčius, D. Sčimku¯naiteė
Underpotential deposition of Cu onto an Se-modified smooth polycrystalline Pt electrode in an acidic CuSO4 solution was investigated using a cyclic voltammetry. It was obtained that the specific voltammetric pattern of Cu UPD observed for a clean Pt electrode disappeared and a new current peak at potentials much closer to bulk Cu deposition was formed. This feature of a cyclic voltammogram is simi...... hiện toàn bộ
Electrocatalysis of the Oxygen Reaction by Pyropolymers of N4 ComplexesRussian Journal of Electrochemistry - Tập 40 - Trang 1174-1187 - 2004
M. R. Tarasevich, K. A. Radyushkina, G. V. Zhutaeva
Results of research into structural and electrocatalytic properties of metalloporphyrins and metallophthalocyanines pyrolyzed on carbon supports of various dispersion degree in the oxygen electroreduction reaction (OER) are analyzed. The pyrolysis products (pyropolymers) that form at T ≤ 800°С in inert atmosphere contain centers Co(Fe)–N surrounded by carbon particles. The oxygen electroreduction ...... hiện toàn bộ
