泡沫炭在环境治理领域应用的研究进展

Research progress in application of carbon foam in environmental treatment

泡沫炭是一种新型炭素材料,它是一种由孔泡和相互连接的孔泡壁组成的具有三维网状结构的轻质多孔材料。相对于传统的多孔材料,泡沫炭因比表面积大、吸附性能优异、结构均匀、热稳定性好、强度高等优点而被用于吸附环境中的各种污染物。同时,在环境治理领域,泡沫炭还可负载各类功能性催化剂,构建吸附与特定功能间的协同效应,提高环境治理效率。泡沫炭具有整体式结构,其作为环境治理材料使用时可表现出良好的可回收性和重复利用性。综述了近年来泡沫炭作为吸附和载体材料在环境治理领域应用的研究进展,展望了泡沫炭未来的研究方向。

Carbon foam is a new type of carbon material.It is a lightweight porous material with a three-dimensional network structure composed of pore cells and interconnected cell walls.Compared with traditional porous materials,carbon foam has been used to adsorb various pollutants in the environment owing to its large specific surface area,excellent adsorption performance,uniform structure,good thermal stability,and high strength.At the same time,in the field of environmental governance,carbon foam can also be loaded with various functional catalysts to build a synergistic effect between adsorption and specific functions and improve the efficiency of environmental governance.Carbon foam has an integral structure which makes it exhibit excellent recyclability and reusability when used as an environmental treatment material.In this paper,the research progress of carbon foams as adsorptive and carrier materials in the field of environmental governance in recent years was reviewed,and the future research direction of carbon foams was prospected.
