Abstract
Porous, polycristalline TiO2 and Nb2O5 photoelectrodes were prepared by a sol- gel process. Small CdS and PbS particles were then deposited onto the electrodes by a wet- chemical method. The particles had diameters of a few nm and showed strong quantization effects. Photoelectrochemical measurements showed a very efficient sensitization of the oxide substrates by the semiconductor particles. The investigation showed that electrons were injected from the conduction band of the photoexcited semiconductor particles.
