二氧化钛(TiO2)光催化技术作为一种绿色、洁净、节能的技术,在污染物治理、光分解水制氢、抗菌环保等领域有着广泛的应用。然而TiO2材料本身大的禁带宽度(Eg=3.2eV)阻碍了其实际应用,进而导致其可见光利用率低、量子产率低。因此制备具有高量子产率且对可见光有快速响应能力的TiO2已成为当前光催化剂研究的关键课题。国内外关于TiO2光催化剂的改性技术逐渐完善并在制备方法、材料形貌和结构控制等方面有新的突破。本文综述了TiO2光催化的制备方法及其反应机理,总结了提高TiO2光催化性能的技术路线,阐明了针对TiO2改性的各种方法的原理及关键技术,同时对TiO2光催化技术存在的问题和发展前景进行了分析和展望。
Abstract：As a green,clean and energy-saving material,titanium dioxide(TiO2) has great potential as a photocatalyst for various applications,including decontamination,hydrogen production from water splitting,sterilization and environment protection.However,large energy gap of TiO2(3.2eV) lead to poor response to visible light and low quantum efficiency,which limited its practical applications.Significant progress has been made in modifying the structure and morphology of TiO2 to overcome aforementioned problems in recent years.In this paper,we review the preparation of TiO2,and illustrate the photocatalytic response mechanism of TiO2 to various contaminants.Different techniques for enhancing the photocatalytic activities of TiO2 in visible light are also summarized.A particular emphasis is placed on revealing the principle and practices of modifying TiO2 using different techniques.Current problems and perspectives of TiO2 photocatalyst are also discussed.
