Ruthenium dioxide-based film electrodes

III. Effect of chemical composition and surface morphology on oxygen evolution in acid solutions

Abstract

Oxygen evolution from acid solutions has been investigated on two kinds of RuO2-based electrodes; compact and cracked (porous) films. The kinetic study has been carried out by means of potentiostatic curves. A method is suggested to estimate the surface concentration of active sites. The reaction order with respect to active sites and the activation energy have been determined. The mechanism is shown to differ on the two kinds of film in relation to theS(site)-OH bond strength and the surface concentration of intermediates. The behaviour of films on silica glass substrates is reported for the first time.
