Mechanism of oxygen reactions at porous oxideelectrodes. Part 2—Oxygen evolution at RuO2, IrO2 and IrxRu1−xO2electrodes in aqueous acid and alkaline solution

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.
