摘要: 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.Abstract: 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.
