Fund Project: Financial support by NNSF (20277046), NSF(990274), EPA(1999-14) and Sci. and Technol. Proj. (A3030502) of Guangdong and The Key Lab. of Environ. Sci. Technol. of Hennan.

Ag-TiO₂/ITO film electrode was used as photoanode to investigate the feasibility of a hybrid technology of Ag nanoparticles combined with the application of anodic bias.The results showed that the deposited Ag and applied anodic bias have an apparent additive effect.
