ABSTRACTVisible-light photocatalytic property of TiO2 / WO3 / FTO multi-layer structure was investigated. In this structure, the visible-light absorption takes place in the WO3 layer, and generated electrons and holes diffuse into the FTO and TiO2 layers, respectively. The holes diffused into the valence band of the TiO2 layer produce the hydroxyl radicals due to oxidation of H2O and/or OH− adsorbed on the TiO2 surface. The FTO bottom layer, which acts as a scavenger of electrons, contributes to an effective charge separation. As a result, the visible-light photocatalysis is enhanced in this structure.
