The anodic evolution of oxygen and chlorine on foreign metal-doped SnO, film electrodes were studied, in connection with their physical and chemical properties. In general, the anodic characteristics of noble metal-doped electrodes were much better than those of base metal-doped electrodes. The oxyg

The chlorine and oxygen overpotential in dependence on the current density i (A cmm2) and on the temperature in the range of 15-75Β°C was measured at y-MnOz and /?-PbO, electrodes in concentrated water solutions of sodium chloride and perchlorate. From the measured values the experimental activation
Ti/SnO, + CuCo,O, and Ti/RuO, + TiO, anodes were used to study oxygen evolution in alkaline solutions and to compare the kinetics on both electrodes. On each electrode the existence of two Tafel regions was confirmed. At low current density (cd) the Tafel slope is 39mV decade-', whereas at high cd i
The chlorine evolution reaction was investigated on several oxide electrodes. The active site on the electrode surface is concluded to be the metal site, based on the dependence of the anodic current on pH of the electrolyte. The reaction mechanism can be determined by the d-electron configuration i
