RESUMO

The performance of semiconducting anodes of TiO2 (natural and synthetic) , SrTiO3 and BaTiO3 in a photoelectrochemical cell was studied. We verified that the natural rutile (TiO2) with small quantity of Fe impurities, might perform the electrolysis of water with an efficiency close to that of synthetic TiO2. The anodic sub-bandgap photocurrent at the TiO2 and SrTiO3 electrodes was examined and we show that it must come from excitation throughout the depletion layer and not just excitation at the surface
