摘　　要：水是生命之源,随着社会和科技的不断发展,水资源短缺、水体污染等问题也不断加重,开发高效、低耗能的水处理技术成为研究的热点。近年来,石墨烯材料因其独特的二维结构和优异的物理化学性质被认为是水处理技术的理想材料,其在吸附、膜过滤等水处理领域的潜能也被不断开发。综述了石墨烯及其衍生物的独特结构及其在水处理领域中呈现的优异性能,从实际应用的角度出发将石墨烯材料以宏观维度进行分类,总结概括了石墨烯粉末、一维石墨烯纤维、二维石墨烯薄膜、三维石墨烯凝胶的制备方法,并对多维度石墨烯材料在吸附、电容去离子、膜过滤、微生物燃料电池领域的应用现状进行了系统总结和归纳。最后,总结了石墨烯材料在水处理领域应用中所面临的问题和挑战,并展望了石墨烯材料在水处理领域的应用前景。Water is an indispensable source for all forms of life. Due to the deteriorating problem of water resource shortage and pollution caused by uncontrolled and abused usage, efficient and energy-saving water treatment technique has attracted substantial research attention. In recent years, graphene is acknowledged to be the ideal material for water treatment due to its unique two- dimensional structure and excellent physical and chemical properties. Meanwhile, the potential application of graphene in the water treatment field, such as absorption and membrane filtration, has been more and more explored. The present paper reviews the unique structures of graphene and its derivatives as well as their outstanding performance in water treatment. Then, graphene materials are categorized from a macro dimension, based on their practical application. The preparation method for graphene powder, one-dimensional graphene fiber, two-dimensional graphene membrane and three-dimensional graphene gel are also summarized. Another contribution of this paper is that the current status of the practical application of multi-dimensional graphene material in absorption, capacitive deionization, membrane filtration and microbial fuel cell are summarized in detail. In addition, the problems and challenges encountered during the application of graphene material in water treatment are summarized and the corresponding perspective is also provided.
