摘要: 二氧化钛（TiO₂）具备无毒、反应条件温和、化学性质稳定等优良特性,是一种前景广阔的光催化材料。但是目前就如何修饰纳米TiO₂缺陷成为光催化领域热门的课题。该文探讨了纳米TiO₂的应用前景,介绍了贵金属修饰复合材料,石墨烯修饰复合材料和半导体修饰复合材料、制备方法,以及TiO₂光催化剂的应用研究进展。

Abstract: TiO₂ is a promising photocatalytic material with nontoxic, mild reaction conditions and chemical stability. But now how to modify defects of nano TiO₂ photocatalyst becomes a hot research topic. This article discusses the application prospect of nanometer TiO₂, and introduces the three kinds of composite materials including the noble metal deposition modifying TiO₂, graphene modifying TiO₂ and semiconductor modifying TiO₂, as well as application review of the nano TiO₂ photocatalyst.
