In this work, TiO2, CeO2/TiO2 and Fe2O3/TiO2 composite oxides, as the novel photocatalysts, were synthesized by ultrasonic dispersion and liquid boiling method, and characterized by X-ray diffraction (XRD) and scanning electron microscope (SEM) and transmission electron microscope (TEM). In addition, the photodegradation performance of the prepared samples were carried out under visible light irradiation, such as the dosage of TiO2, CeO2/TiO2 and Fe2O3/TiO2 composite oxides, the visible light irradiation time, heat-treated temperature and heat-treated time. Results revealed that the CeO2/TiO2 composite oxide exhibits better photocatalytic activity for the degradation of dye
