摘　　要：近年来,水资源污染和短缺问题日益突出,对水质的修复保护工作至关重要。纳米TiO2作为一种高效节能的光催化功能材料,在水质修复领域有广泛的应用前景,同时也面临着一些挑战。如何提高纳米TiO2材料的催化活性和光催化效率,成为当前的研究热点。针对近年来TiO2光催化的研究和在水质修复领域的应用进展,对不同形态的纳米TiO2的制备、改性研究进展进行了综述,在此基础上全面介绍了纳米TiO2作为光催化剂处理不同污染水质的应用现状,并对今后的研究发展方向进行了展望。As water pollution and water shortage continue to get worse in recent years, it is urgent and essential to protect and restore the water quality. Nano-TiO2 , as an efficient photocatalytic functional material, has broad appli- cation prospects in the field of water quality restoration. However, it still presents some disadvantages such as limit- ed activity and reduced sensitivity to sunlight. Therefore, how to improve the activity and efficiency of nano-TiO2 photocatalyst has become a major research focus. In this paper, the technological progress in nano-TiO2 photocata- lyst with respect to its preparation and modification as well as its application in the field of water quality restoration are reviewed. Meanwhile, the future research orientations are presented.
