Abstract

Abstract: Nanosize Fe³⁺-doped TiO₂ particles were prepared by the hydrothermal method with TiCl₄ 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%Fe³⁺-doped TiO₂ has a higher photocatalytic activity than TiO₂.
