| 摘 要： | 通过溶胶 凝胶法，直接在导电的金属镍基上制备多孔TiO2纳米薄膜，利用STM观察电极的表面形貌，所制TiO2粒径约为20～80 nm，随着烧结温度的升高，TiO2纳米薄膜表面孔的数量增多、孔径增大.用循环伏安法分析了电极的光电化学性能，结果表明，电极的光电响应随烧结温度的升高和薄膜厚度的增加而增大.

| Abstract: | Nanosized porous TiO2 films supported on nickel are prepared by sol gel process. The STM morphology of the nanosized TiO2 films has been given. It is known by STM, that the diameter of TiO2 particles is about 20～80 nm and the pore quantity and the diameter of nanosized TiO2 film increase with the increasing of sintering temperature. The photoelectrochemical performance of the prepared TiO2 photoelectrode is determined by cyclic voltammitric method. It is found that the photocurrent of the photoelectrode increases with the increasing of the sintering temperature and thickness of TiO2 film. |
