光催化剂TiO_2的改性研究进展

Research on Modification of Photocatalyst TiO_2

光催化剂TiO_2在环境污染治理领域呈现出广阔的应用前景,但由于其自身存在不能响应可见光和量子效率低的缺陷而限制了它的应用,改性是提高TiO_2光催化性能的重要手段。在总结国内外科研成果的基础上,综述了现阶段TiO_2的主要改性方法(如光敏化、离子掺杂、复合半导体等)研究进展,并对TiO_2改性方法的发展趋势进行了展望。

As a photocatalyst, TiO2, had more and more extensive and promising application in several fields such as environment protection, while non-responding to visible light and low quantum yield limit application in many fields. Modification of TiO2 could improve its performance effectively. The modification techniques, such as dye sensitization, ion-doping and composite semiconductors, et al, were summarized. The research and development of modification of TiO2 in the future were forcasted.
