Abstract :
Ce doped TiO2 particle can be prepared by sol-gel method. According to XRD analysis, by Ce doping, the diffraction maximum is broadened, the particle size reduced and TiO2 crystal transition prevented. The result of photo catalytic degradation of Cr suggests that photo catalysis activity of doped TiO2 claimed at 50017 will reach the highest point when Ce doping concentration is 0.05%.
