Aba&act -The electrocatalysis for the chlorine evolution reaction on RuOs and Ir02 electrodes was &US& on the ba.& of& activation energy. The activated complex with the pentagonal bipyramid-type structure was speculated to be formed in the transition state for the Heymvsky reaction. The activation e
H, evolution from acid solutions has been studied on IrO, + RuO, electrodes over the whole oxide composition range. Kinetics has been investigated by means of cyclic voltammetry, quasistationary current-potential curves and reaction order determination. Results have shown that the Tafel slope for as
## Thechlorine and oxygen evolution reactions have been investigated on various compositions of Ti supported Ru0,/Ti02 anodes. Conclusions have been reached on the structure of the electrode, and its influence on the mechanism of these two reactions, at the different compositions of Ru0JI'i02.
