Abstract:

The photoelectrochemical behaviors and mechanisms of the nanocrystalline TiO2 films prepared using different preparation methods were studied .The results showed were studied . The results showd that the photoelectrochemical behaviors of nanocrystalline TiO2 films were different from that of compact semiconductor electrodes. The photoelectrochemical behaviors were ascribed to the existence of particles in TiO2 films. The mechanisms were suggested by means of both traditional semiconductor model and colloidal semiconductor model.

Key words: Nanocrystalline TiO2 Films, Photocurrent, Thermal decomposition, Electrodeposition, Ionic sputtering technique
