摘要

从三维石墨烯基光催化剂的制备、3D GBP的分类以及基本作用等方面对三维石墨烯基光催化剂进行综述，分析了三维石墨烯促进所负载催化剂电子-空穴高效分离、光吸收范围变宽以及污染物吸附性能提高的原理。此外，还综述了化学掺杂N和B原子石墨烯基底对三维石墨烯基光催化剂（3D GBP）催化性能的重要影响。

Abstract

The 3D graphene based photocatalysts (GBP) are overviewed from three aspects of preparation,classification and basic function.The principles for 3D graphene helping its supported catalysts to separate electron-hole efficiently,widen the light absorption range and improve adsorption against pollutants are analyzed.In addition,the important influences of the graphene substrate with chemically-doped N and B atoms on the catalytic performance of 3D GBP are overviewed.
