| 英文摘要 | The TiO2-N-x% WO3 composite photocatalysts were prepared by introducing WO3 into nitrogen- doped TiO2. The composite catalysts present much higher photocatalytic activity than TiO2 and nitrogen-doped TiO2 under both ultraviolet and visible light irradiation. Diffuse reflectance UV- vis spectra, XPS analysis, and IR spectra show that the coordinated nitrogen species ( or N- metal- O linkages) may contribute to the visible light photocatalytic activity. WO3 coupling increases the active nitrogen species and thus enhances the visible light activity of the composite photocatalysts. The superior activity of TiO2- N- x% WO3 composite photocatalysts upon UV light irradiation can be rationalized in terms of efficient charge separation and high adsorption affinity of WO3. |
