Abstract
Vanadium doped rutile titania was prepared by low temperature hydrolysis using Tetrabutyl titanate as raw material. Powers were characterized by X-ray diffraction spectrum (XRD)、diffuse reflection spectra(DRS)、fluorescence spectra (FS). At 1073K, Doped concentration have been in a certain range, Vanadiumcould be doped into the lattice of rutile TiO2in the way of replacement, which would cause no change in rutile TiO2crystalline state with sunlight as the light source, pH=6.0, catalyst concentration was 1.0g.L-1, concentration of methyl orange was 5.0mg.L-1. It has been shown that Vanadium doped TiO2powders(1.0%,1073K) has been the most photodegradation efficiency, and the degradation efficiency was 97.2% after 6h.
