二维纳米材料在水处理中的应用研究进展

Progress in application research of two-dimensional nanomaterials in water treatment

随着工业的发展,原油泄漏事故的频发和工业污水的排放给全球生态环境及人类的健康带来了巨大的威胁。近年来,水污染问题也越来越受到人们的重视。纳米材料的出现为实现高效、低成本的水处理技术提供了新思路。近些年,以石墨烯、氮化硼纳米片以及二硫化钼纳米片为代表的二维纳米材料先后被科学家制备出来。由于它们具有较大的比表面积,因此有很强吸附性,也迅速成为水处理领域的研究热点。主要介绍了石墨烯、氮化硼纳米片以及二硫化钼纳米片3个典型二维纳米材料在水处理领域中的最新研究进展,并且总结了它们各自作为水处理材料的特点。最后,展望了它们的发展趋势。

With the development of industry,the issue of water pollution,which is caused by frequent oil leakage accidents and the discharge of industrial sewage,has caused great harm to the global ecological environment and human health.In recent years,water pollution is getting more and more attention.The appearance of nanomaterials provides a new way for highefficiency and low-cost water treatment.In recent years,two-dimensional nanomaterials,such as graphene,boron nitride nanosheets and molybdenum disulfide nanosheets,have been prepared by scientists.Because of their large specific surface area,they have strong adsorption ability,and quickly become a research hotspot in the field of water treatment.The latest research progress of three typical two-dimensional nanomaterials in the field of water treatment,including graphene,boron nitride nanosheets and molybdenum disulfide nanosheets,were introduced and their characteristics as water treatment materials were summarized.Finally,their development trend was prospected.
