Abstract: 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 application prospects in the field of water quality restoration. However, it still presents some disadvantages such as limited 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 photocatalyst 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.

Key words: nano-TiO2, photocatalyst, preparation, modification, water quality restoration
