Abstract：Titanium-Baring Blast Furance Slag（TBBFS）， as a photocatalyst material, its quantum efficiency and utilization of solar energy are very low. Because of the special electronic structure, the rare earth elements are of good semiconductor properties in the formation of oxides. And to some extent, the mixture of the metal oxide-doped can improve the light catalytic properties of the Titanium-Baring Blast Furance Slag. In this study, Titanium-Baring Blast Furance Slag that is mixed with rare earth oxide is used in Degradation experiment of the methylene blue solution under the condition of the Ultraviolet radiation and many Analytical methods such as ray diffraction experiments (XRD), scanning electron microscopy (SEM)are used to find out the Optimum amount of rare earth doped. The results show that when the dopings of the rare earth element CeO2, Y2O3 are respectively 0.5%，1.0%, their degradation rates of methylene blue will respectively get to 72.2%，74.0%, which are the optimal doping.
