The polarization behaviors of various oxide electrodes prepared on graphite substrate by thermal decomposition procedure have been investigated by linear sweep voltammetry in chloride melt at 700 . Experimental results showed that some oxides have obvious electrocatalytic activity for chlorine evolution, lowering anodic overpotential up to 80110 mV at a current density of 0.6 A/cm2. The kinetic analysis of steady state JE data in terms of Tafel slopes and chronocoulumetric measuring inferred that the mechanisms of CER on RE oxide electrodes was atom+ion route, with Heyrovsky reaction (Clads+Cl-Cl2+e) being the ratedetermining step, and the adsorption of intermediate species Clads obeying noactivated Temkin condition.
