英文摘要：

Cu-based quantum dots are easy to synthetize and can replace dye, CdS quantum dots and etc. , as sensitizer of TiO2 due to their advantages of low cost, non-toxic, good catalytic activities, and narrow band gap. The progresses in in-situ or ex-situ deposition of Cu-based quantum dots on TiO2 , the photon absorption abilities and the charge transfer properties of TiO2 sensitized by Cu-based quantum dots, and their applications in different fields were reviewedin this paper. In addition, research focused on TiO2 sensitized by Cu-based quantum dots for photocatalytic hydrogen production in the near future were also analyzed and discussed.
