摘　　要：钛酸纳米管具有高比表面积和光化学稳定性等特点,在光催化领域得到广泛的研究。为了拓宽可见光吸收范围和提高量子产率,需要对其进行改性。本文介绍了金属离子掺杂、贵金属沉积及复合半导体对钛酸纳米管光催化剂的改性研究最新进展,分别从实验制备及掺杂后的光催化特性入手,分析了各种改性方法的作用机理。最后指出了钛酸纳米管改性的进一步研究方向。Titanate nanotubes with a high ratio of surface area and photochemical stability have been studied widely in the photocatalytic field. The modification methods of titanate nanotubes are adopted to broaden the photoabsorption region and improve photo-quantum efficiency. The recent progress in three modification methods （metal ion doping, rare metal deposition, and compounding semiconductors） in a few aspects including preparation methods,modification in photocatalytic properties and the working mechanism of different modification methods, is presented in this paper. Moreover, some further stud）＇ on modification methods of titanate nanotubes photocatalysts is also suggested.
