Research on Visible Light Photocatalytic Performance of Tungsten Doped TiO₂

Abstract:

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.
