The evolution of chlorine bubbles on technologically important anodes has been studied using in situ microscopy and measurements of electrochemical noise. Images of RTO (ruthenium-titanium oxide) electrode surfaces evolving gas show that the surfaces display heterogeneous bubble detachment kinetics.
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 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
