摘　　要：Nanostructured TiO 2 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 TiO 2 film.Through STM,the pore quantity and diameter of nanostructured TiO 2 film were found to increase with the increment of sintering temperature.It was found that the transparence of different thickness nanostructured TiO 2 films coated on quartz did not change much.Nanostructured TiO 2 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 TiO 2 film.Through STM,the pore quantity and diameter of nanostructured TiO 2 film were found to increase with the increment of sintering temperature.It was found that the transparence of different thickness nanostructured TiO 2 films coated on quartz did not change much.
