Description

A better understanding of the fundamental aspect of electrocatalysis is sought by a systematic study of the chlorine evolution reaction at Ru/Ti, Ir/Ti and Ir + Ru/Ti mixed oxides. Electrodes of controllable composition are generated by electrochemical oxidation of near-surface implanted titanium alloys. The reaction is studied concurrently by electrochemical measurements and by in situ photoacoustic spectroscopy. Changes in the spectra in the wavelength region including the absorption band edge of semiconducting n-TiO2 with composition provide a means for probing the electronic structure of the mixed oxide layer. The spectroscopic results are correlated with the Tafel slope data
