英文摘要：

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.
