TiO2/Pt/glass and TiO2/glass thin films in nanocrystalline have been prepared by solgel method and their structures and elctrochemically assisted photocatalysis have been examined. The results of electrochemically assisted photocatalytic degradation of dye solution by thin films indicate that the photocalytic activities of TiO2/Pt/glass thin films are higher than that of TiO2/glass thin films. Also, a more higher photocatalytic activity of TiO2/Pt/glass thin films can be achieved when an anodic bias is applied, and it increses with the increase of anodic bias. Forthermore, light showed effects on the photocatalytic activity of the thin film.
