摘　　要：本文综述了石墨烯(GR)分别作为电子受体、催化剂垫、敏化剂在石墨烯基二氧化钛(GR-TiO2)光催化剂中的作用,总结了GR-TiO2的制备方法,系统介绍了GR-TiO2在光催化分解水制氢、光催化降解污染物等领域的最新研究进展,认为GR-TiO2吸附作用的研究、实现对催化剂简单易行的回收利用等方面是GR-TiO2未来的研究趋势。This paper reviewed the role of graphene respectively as electron acceptor,catalyst mat,sensitizer in the graphene-based titanium dioxide（ GR-Ti O2） photocatalyst,summarized the preparation methods of GR-Ti O2. The current development of the utilization of GR-Ti O2 in photocatalytic hydrogen generation from water,photocatalytic degradation of pollutants was systematically introduced. It was thought that to study on the adsorption of GR-Ti O2 and to realize the economic recycling of the GR-Ti O2 catalyst were the future research trends.
