| 摘 要： | The FTO/TiO2 seed layer/TiO2 nanorods were prepared by ion beam deposition and hydrothermal methods. Under UV light, the photocurrent density of FTO/TiO2 seed layer/TiO2 nanorods can reach 1.39 mA/cm2, which is higher than that without seed layer and nanorods structure. Not only that, the FTO/TiO2 seed layer/TiO2 nanorods can also adsorb visible light, which overcomes the defect that traditional TiO2 can not absorb visible light. The photocurrent density of FTO/TiO2 seed layer/TiO2 nanorods can reach 0.21 mA/cm2 under visible light. The increased performance resulted from the deposition of the TiO2 seed layer, which can reduce the band gap of TiO2. FTO/TiO2 seed layer/TiO2 nanorods also exhibited high photodegradation ability for organic pollutant methylene blue (MB). Within 120 min, 77.3% MB can be degraded, and the degradation rates remained almost unchanged after four cycles. Not only that, compared with powdered photocatalysts, FTO/TiO2 seed layer/TiO2 nanorods is easy to recover, and it can be reused by rinsing it with water several times and drying it naturally after the reaction.
