Fluorine-doped tin oxide (FTO)/TiO2 seed layer/TiO2 nanorods were prepared by ion-beam deposition and hydrothermal methods. Under UV light, the photocurrent density of these nanorods was found to reach 1.39 mA/cm2, which was higher than that without the seed layer and nanorod structures. Furthermore, the FTO/TiO2 seed layer/TiO2 nanorods can also absorb visible light, overcoming a notable problem with standard TiO2. The photocurrent density of the FTO/TiO2 seed layer/TiO2 nanorods was found to reach 0.21 mA/cm2 under visible light. This high-performance results from the deposition of the TiO2 seed layer, which reduces the band gap of TiO2. The FTO/TiO2 seed layer/TiO2 nanorods also exhibited high photodegradation ability for the organic pollutant methylene blue (MB). Within 120 min, 77.3％ of the MB was found to have been degraded, and the degradation rates remained almost unchanged after four cycles with the same catalyst sample. Additionally, compared with powdered photocatalysts, the FTO/TiO2 seed layer/TiO2 nanorod sample is easy to recover, requiring only rinsing with water and natural drying after the reaction.
