N2 - Previous studies have shown that ternary IrO2-Sb 2O5-SnO2 is among the best electrocatalysts for O2 evolution. Its high stability and low Ir content make it more attractive than IrO2 and many other electrocatalysts. In this paper, the electrochemical stability and activity of the Ti/IrO2-Sb 2O5-SnO2 electrodes prepared under different conditions were investigated. It was found that the calcination temperature and Sb and Ir contents could affect the stability and activity significantly. The optimal calcination temperature, and Sb content are 550°C and 15 mol %, respectively. The stability and activity increased with an increase in the Ir content in the investigated range of 0-10 mol %. Physicochemical analysis showed that the IrO2-Sb2O5-SnO2 coatings obtained were oxide solid solutions even at a Sb content up to 25 mol % and had compact microstructure when Sb ≤ 15 mol %. © 2005 The Electrochemical Society.
