Abstract
Originated from(C4H9O)4Ti, TiO2was synthesized by low temperature hydrolysis process in this paper. After being prepared by decomposing ammonium tungstate and covering on the surface of TiO2, TiO2/WO3were characterized by XRD, DRS, FS. With sunlight as the light source, pH=5.0, catalyst concentration was 1.0g.L-1, concentration of methyl orange was 5.0mg.L-1.It has been shown that TiO2/WO3powders(15%,873K) has the most photodegradation efficiency, and the degradation efficiency of 95% after 4 hours.
