Research on Visible Light Photocatalytic Performance of Tungsten Doped TiO2
In this paper, W-doped rutile titania was prepared by low temperature hydrolysis using Tetrabutyl titanate. Powers were characterized by XRD、DRS、PL. At 1073K, Doped concentration have been in a certain range, Tungsten could be doped into the lattice of rutile TiO2 in the way of replacement, which would cause no change in rutile TiO2 crystalline state with sunlight as the light source, pH=2.0, catalyst concentration was 1.0g.L-1, concentration of methyl orange was 5.0mg.L-1. It has been shown that Tungsten doped TiO2 powders(1.0%,1073K) has been the most photodegradation efficiency, and the degradation efficiency was 96.8% after 12h.
