| Abstract: | Fe3 doping can improve the photocatalytic activity of TiO2 nanoparticles films electrode. The surface states of Fe3 doped TiO2 film electrodes were investigated by electrochemical method,and the relative parameters were acquired. The density of holes on electrode surface increased so that the photocatalytic activity improved. The mechanism of Fe3 doped TiO2 on photoelectrooxidating of methanol can be explained. |
