Abstract
The kinetics and mechanism of the oxygen evolution reaction at a series of RuO2 /IrO2 mixed oxides in aqueous acid and alkaline solution has been examined using a variety of electrochemical methods. Factors affecting the electrocatalytic activity have been elucidated and novel oxygen evolution mechanisms in terms of reactive oxyruthenium and oxyiridium surface groups are proposed.Keywords
