The porous TiO 2 anatase nanometer thin films were prepared from titania powder by ultrasonic wave and dip coating technique. Its photo electrocatalytic performance for the oxidation of methanol was investigated.

• TiCl4为原料采用常压沸腾回流工艺合成的纳米TiO2 粉体 ,经超声分散成溶胶后 ,用浸渍提拉的方法将TiO2 固定在导电玻璃上制成多孔纳米薄膜光电复合催化剂 ,并就该催化剂对甲醇的光电复合催化氧化性能进行了研究。
