采用水热法在导电玻璃（ FTO）上合成具有一维结构的TiO2纳米棒阵列薄膜．用扫描电子显微镜，广角X?射线粉末衍射，紫外可见分光光谱等手段对薄膜进行了表征，研究了不同浓度钛酸四丁酯和水热反应时间对FTO?TiO2纳米棒阵列薄膜形貌的影响及FTO?TiO2纳米棒阵列薄膜光催化还原Cr（Ⅵ）的反应性能．结果表明，当钛酸四丁酯浓度为0．05 mol·L－1和水热反应时间为20 h时制备的FTO?TiO2纳米棒阵列薄膜形貌最优，一维FTO?TiO2纳米棒阵列薄膜光催化还原Cr（Ⅵ）的性能优于商业化二氧化钛 P25制备的薄膜．
One dimensional TiO2 nanorod array films on conductive glass ( FTO) were prepared with a hydrothermal method. The obtained films were characterized by X?ray diffraction, scanning electron microscopy, transmission electron microscopy and UV?vis diffuse reflectance spectroscopy. Influence of tetrabutyl titanate concentration and water thermal reaction time on the morphology of FTO?TiO2 nanorods array films and the photocatalysed reduction of Cr(Ⅵ) using FTO?TiO2 nanorods array films were studied. The results indicated that optimum conditions for preparing optimal morphology of FTO?TiO2 nanorods array films were found as follows:tetrabutyl titanate concentration 0.05 mol·L-1 and water thermal reaction time 20 h. FTO?TiO2 nanorod array films performed much better in photocatalysed reduction of Cr(Ⅵ) than the commercial P25 films.
