光催化被认为是解决环境问题十分有前景的方法之一。三维石墨烯气凝胶(3DGA)是一种新颖的光催化材料,具有独特的多孔结构和优异的载流子迁移性能,常被用作支撑和增强半导体催化活性的催化剂。分析了负载光催化剂的3DGA的催化机理,并综述了3DGA在空气污染物、水污染物和抗生素等环境领域的部分处理方法,举例了解了如元素掺杂、构建异质结、Z型异质结等常见的3DGA光催化机制。
Photocatalysis is considered to be one of the very promising methods to solve environmental problems.Three-dimensional graphene aerogel (3DGA) is a novel photocatalytic material due to its unique porous structure and excellent carrier transfer performance;therefore,it is often used as a catalyst to support and enhance the catalytic activity of semiconductors.This article analyzed the catalytic mechanism of photocatalyst-loaded 3DGA and summarized some of the treatment methods of 3DGA in the environmental fields of air pollutants,water pollutants and antibiotics.An example was given to understand the common 3DGA photocatalysis mechanism such as element admixture,construction of heterojunction,and Z-type heterojunction.
