Ti(IV) oxide has been an important semi-conductor material in photoelectrochemical cell, especially in the area of developing photochemical nanocrystalline solar cell. The TiO2 films were deposited on SnO2 (F-doped) glass electrodes by anodic oxidative hydrolysis of acidic aqueous TiCl3 solutions. The films are uniform in thickness, have an average size of approximately 20nm, and have the anatase structure after annealing at 450℃. The method of anodic oxidative hydrolysis, the method of electrodepositing high pure TiO2 (anatase) on transparent conducting oxide (TCO) glass, condition of producing TiO2 film, and some character of the film have also been investigated.
