摘要

This study proved the significance of simulated sunlight irradiation response capability of Sn-F co-doped TiO_(2)/SiO_(2)(Sn-F-TiO_(2)/SiO_(2))photocatalysts,which were prepared by a simple sol-gel method and were evaluated by acrylonitrile degradation for photocatalytic activity.The synthesized catalysts were characterized by X-ray Diffraction(XRD),Scanning Electron Microscopy(SEM),Energy Dispersive Spectrometer(EDS),X-ray Photoelectron Spectroscopy(XPS),Brunauer-Emmett-Teller(BET),Ultraviolet-Visible Absorption spectroscopy(UV-Vis),and Photoluminescence Spectroscopy(PL).UV-Visible spectroscopy demonstrated that Sn doping caused remarkable red shift in TiO_(2),which significantly increased the absorption efficiency of the catalysts.The XPS results showed that Sn was successfully doped into the TiO_(2) lattice.The photocatalytic degradation of acrylonitrile indicated that the Sn-F-TiO_(2)/SiO_(2) photocatalysts exhibited excellent photocatalytic activity when being annealed at 550℃for 2 h.The degradation rate of acrylonitrile reached 67.7%after irradiation under simulated sunlight for 6 min,and the hole was the most important active species.
