WO₃ and Bi₁₂SiO₂₀ powders were prepared by a gas-liquid reaction and chemical solution decomposition, respectively. WO₃/Bi₁₂SiO₂₀ photocatalysts were coupled by mixing WO₃ and Bi₁₂SiO₂₀. The reduction of benzene was used to investigate the activity of WO₃/Bi₁₂SiO₂₀. The results indicate that the activity of the coupled WO₃/Bi₁₂SiO₂₀ catalysts increased substantially. The degradation behavior of benzene over 30%(w) WO₃/Bi₁₂SiO₂₀ under UV irradiation was obviously better than that of P-25, and the degradation of benzene under visible light was also considerable. The photocatalysts were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS) and UV-Vis diffuse reflectance spectroscopy (UV-Vis DRS). The results showed that there was a od synergistic effect between WO₃ and Bi₁₂SiO₂₀. The photogenerated electrons and holes were effectively separated after coupling between WO₃ and Bi₁₂SiO₂₀ and the rate of electron and hole production increased. The electrons and holes were effectively separated and the photocatalytic activity increased accordingly.
