摘要
电容去离子(CDI)技术具有能耗低、再生效率高、无二次污染、易于操作等优点,在解决水资源短缺和水环境污染方面应用广泛.开发具有高电化学性能和盐吸附能力的电极材料是CDI脱盐的关键.碳材料因其高比表面积、丰富的孔隙结构、优异的导电性和良好的稳定性而被广泛用作CDI电极.本文在介绍CDI技术基本原理的基础上,综述了5 类典型碳基电极材料的研究进展,重点是材料设计和改进的吸附性能.对比分析了不同种类电极材料之间的优缺点,探讨了工业化存在的问题及改进方向.
Abstract
Capacitive deionization(CDI)technology is widely used in solving water shortage and water environment pollution,which has the advantages of less energy consumption,high regeneration efficiency,no secondary pollution and easy operation.Developing electrode materials with high electrochemical performances and salt adsorption capacity is vital for CDI desalination.Carbon materials have been extensively used as CDI electrodes because of their high specific surface area,abundant pore structure,excellent electrical conductivity and good stability.On the basis of introducing the basic principle of CDI technology,this paper summarized the research progress of five types of typical carbon-based electrode materials,with the emphasis on material design and improved adsorption performances.The advantages and disadvantages of different kinds of electrode materials were compared and analyzed,and the problems existing in industrialization and the improvement directions were discussed.
