Compared with the traditional wastewater treatment technology, semiconductor photocatalysis is a rapidly emerging environment-friendly and efficient Advanced Oxidation Process for degradation of refractory organic contaminants. Single-component semiconductor photocatalysts exhibit poor photocatalytic performance and cannot meet the requirements of wastewater treatment. The combination of semiconductor photocatalysts and Graphene can effectively improve the photocatalytic activity and stability of semiconductor photocatalysts. This review focuses on the synergistic effect of several types of semiconductors with Graphene for photocatalytic degradation of organic pollutants. After a brief introduction of the photodegradation mechanism of semiconductor materials and the basic description of Graphene, the synthesis, characterization and degradation performance of various Graphene-based semiconductor photocatalysts are emphatically introduced.
与传统的废水处理技术相比，半导体光催化是一种新兴的环保且高效的高级氧化工艺，可用于降解难处理的有机污染物。单一成分的半导体光催化剂表现出较差的光催化性能，无法满足废水处理的要求。半导体光催化剂与石墨烯的结合可以有效地提高半导体光催化剂的光催化活性和稳定性。本综述重点介绍了几种类型的半导体与石墨烯的协同作用，用于光催化降解有机污染物。在简要介绍半导体材料的光降解机制和石墨烯的基本描述之后，重点介绍了各种基于石墨烯的半导体光催化剂的合成、表征和降解性能。
