| Abstract: The InVO4-TiO2 nano-crystalline photocatalyst was prepared by sol-gel method and characterized by DRS, FTIR, Raman and XRD. The photocatalytic activities of the prepared sample were investigated by photocatalytic degradation of ethylene in the gaseous phase under visible light irradiation (λ>450 nm). The results indicate that both of pure TiO2 and InVO4 or their simple mixture show no photocatalytic activities for degradation of ethylene under visible light irradiation. However, as-synthesized InVO4-TiO2 catalyzes the degradation of ethylene into CO2 under visible light irradiation. In addition, the interaction between InVO4 and TiO2 results in some structural distortion to all the crystal forms of TiO2 in as-synthesized catalyst InVO4-TiO2. |
