Effect of the Ce-doped TiO2 on the Photocatalysis Degradation of MB

摘要：

　　In this paper, we prepared a series of powders (pure TiO2 and Ce-doped TiO2) by sol-gel method and characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), infrared spectrometer (IR) and UV spectrophotometer.The results indicated that the doped Ce influence the crystal structure of TiO2 and improve the temperature of crystal transformation.In the degradation of MB experiment, after 5 hours, the degradation efficiency of them(pure TiO2, Ce-doped TiO2 and P25) under UV light is about 99.1%, while under visible light, Ce-doped TiO2 is about 60% higher than pure TiO2 and P25, up to 73%.This illustrates that the doped Ce increase the absorption to visible light and improve the photocatalytic efficiency.
