PREPARATION AND PROPERTIES OF NANOSTRUCTURED TiO2 POROUS FILM

Abstract Nanostructured TiO2 porous film supported on nickel was prepared through sol- gel process, and was used as photoelectrode in solar energy photoelectrochemical cell. It was found that short circuit photocurrent and open circuit photovoltage of the photoelectrodes increased with the increment of sintering temperature and thickness of TiO2 film. Through STM, the pore quantity and diameter of nanostructured TiO2 film were found to increase with the increment of sintering temperature. It was found that the transparence of different thicknes
