摘要
Bi-doped TiO2 was prepared with sol-gel method and was characterized by X-ray photoelectron spectroscopy (XPS). The photocatalytic degradation and kinetics of Methyl orange with Bi-doped TiO2 under xenon lamp irradiation were investigated. The optimum conditions were as follows: the initial concentration of Methyl orange was 20 mg/L, the value of pH was 3.0 and the dosage of Bi-doped TiO2 was 1.0 g/L. Under the optimal conditions, the decolorization rate of Methyl orange was 75.1 % and the kinetic constant was 0.0113 min(-1).
