Synthesis and Characterization of TiO2/CuO/WO3 Ternary Composite and its Application as Photocatalyst

Photocatalytic removal of water and air pollution has received much attention today. Many photocatalysts based on semiconductors have been developed used. Binary even ternary composites to solve the drawback semiconductors, including high band gaps short life time charge carriers. In this study, a three-component composite TiO2/CuO/WO3 was synthesized by adding WO3 TiO2/CuO. Their structural properties were evaluated analyzes X-ray diffraction (XRD), field-emission scanning electron microscopy (FESEM), diffusive reflectance spectra (DRS) their performance methylene orange dye removal. The results XRD SEM analysis showed purity uniform distribution elements. combination TiO2/10%CuO 15%WO3 with gap 2.66 eV highest rate constant (0.0301 min-1).
