【摘要】本研究采用溶胶凝胶法制备含铁离子的二氧化钛多孔纳米薄膜,并将其作为光催化剂,光降解反应结果表明,含铁二氧化钛复合纳米薄膜的光催化活性明显提高.光电化学研究表明,铁离子可以形成电荷陷阱,促进空穴的界面传递反应,从而提高了光催化活性.更多还原

【Abstract】 In the research,Fe3+/TiO2porousnanofilm has been synthesized by using SolGel method.The photocatalytic results show that nanocrystalline TiO2 codoped with Fe3+ dopants enhances the photoreactivity significantly. The effects of the Fe3+ dopants in nanocrystalline TiO2 particles on the photocatalysis were studied by using the photoelectrochemical method.Fe3+ serves as chargecarrier traps and promote holes interfacial transfer reaction.更多还原
