【Abstract】 Nanosize Fe 3+-doped TiO 2 particles were prepared by the hydrothermal method with TiCl 4 as the precursor. The products obtained under different conditions were characterized by means of XRD. The influences of various hydrothermal conditions including reaction time, temperature, and pH were investigated. The photocatalytic activity of the catalysts was tested with Rhodamine B as the objective decomposition substance. The results show that the 0.1%Fe 3+-doped TiO 2 has a higher photocatalytic activity than TiO 2.更多还原
