三维石墨烯材料在污水处理中的研究进展

Development of 3D graphene material in wastewater treatment

随着生态环境的日益恶化,水体污染越来越引起人们的关注.吸附法是去除水体污染简单环保的有效方法.由二维石墨烯相互搭建构筑而成的多孔柔软三维石墨烯材料,具有高表面积、丰富的官能团以及快速的电子转移能力,对多种水体污染物都具有一定的吸附性能.文章对三维石墨烯材料对染料、金属离子、油类等多种水体污染物的吸附性能进行了综述.

Elimination of water pollutants is drawing increasing attention as the ecosystem keeps deteriorating.Adsorption is a simple but effective method in removing pollutants from water.Recently,3-Dimensional graphene based materials（3DGM） have been developed as the next generation adsorbents in both water and wastewater treatments.3DGM,a collective structure of groups of mutually connected 2-dimensional graphene,is an ideal material in controlling water pollution due to its high surface area,well-defined porous structure and high surface electron mobility.In this paper,we reviewed the performances of 3DGM in adsorbing different water pollutants（e.g.dyes,metal ion,oils,etc.） in terms of the structure properties.
