Abstract:Composite photocatalysts TiO2/WO3 were prepared by hydrothermal method using sodium tungstate and tetrabutyl titanate as raw materials. The structural and morphology of TiO2/WO3 were characterized by XRD、SEM、BET and Raman. The results show that WO3 in the TiO2/WO3 is in monoclinic phase, composite material is micro linear structure with uniform dispersion. The photodegradation of MB was used to evaluate the photocatalytic activity of the catalysts. 71.52% and 85.76% MB are degraded by WO3 and TiO2/WO3 within 70 min. The decolorization experiment for MB solution (10 mg/L) indicated its excellent decolorization performance.Composite photocatalysts TiO2/WO3 were prepared by hydrothermal method using sodium tungstate and tetrabutyl titanate as raw materials.
