Abstract:

Mesoporous TiO2/CdS thin film photoelectrode was successfully prepared by electrodeposition CdS nanoparticles on mesoporous TiO2 thin film. The products were characterized by XRD, SEM, Raman, SPS and UV-Visible spectra. The results revealed that CdS nanoparticles were successfully deposited on the surface and in the hole of mesoporous TiO2 thin film. The photoelectric property of these films were investigated by photocurrent action spectra. The results show that the composite films exhibited enhance photoelectric conversion efficiency compared with mesoporous TiO2 thin films. This may be attributed to the character of CdS and the formation of mesoporous TiO2/CdS heterojunction.

Key words: Mesoporous TiO2; CdS; Electrodeposition; Photoelectric property
