Abstract

The effect of substituting SnO2 for TiO2 in RuO2+TiO2 electrodes has been studied by varying the SnO2 content systematically in a series of oxides of general composition 30 mol% RuO2+x mol% SnO2+(70-x) mol% TiO2. The surface properties have been investigated by voltammetric curves, the electrocatalytic activity by using O2 evolution from 1 mol dm−3 HClO4 solutions as a test reaction. It has been observed that only the surface area changes at intermediate compositions as a result of morphological modifications, while the electrocatalytic activity increases dramatically as the substitution of SnO2 for TiO2 becomes complete. Reasons for that are discussed. The present results do not support the claim that SnO2 depresses the electrocatalytic activity of oxide electrodes for oxygen evolution.
