【摘要】：电容去离子(CDI)是一种通过静电力作用将离子从水中去除的技术,电极是整个装置中为最为核心的部件,石墨烯因具有优异的导电性和巨大的比表面积等优势成为当前CDI电极材料的研究热点之一。目前对于CDI石墨烯电极的研究主要集中于石墨烯电极的合成,然而有关CDI性能与石墨烯电极制作工艺及电极材料自身结构之间的关系,缺少相关综述。本文系统介绍了CDI的基本原理与性能指标,综述了石墨烯电极材料的研究进展与电极制作工艺,重点分析、归纳和总结了石墨烯材料的特性(孔隙结构、导电性、亲疏水性)对CDI性能的影响,最后对CDI中石墨烯电极材料今后的发展进行了总结和展望。
[Abstract]:The capacitive deionization (CDI) is a technique for removing ions from water by electrostatic action. The electrode is the most important component in the whole device. Graphene has become one of the research hotspots in CDI electrode materials because of its excellent conductivity and large specific surface area. At present, the research of CDI graphene electrode is mainly focused on the synthesis of graphene electrode. However, the relationship between CDI properties and graphene electrode fabrication process and the structure of the electrode material is not reviewed. In this paper, the basic principle and performance index of CDI are introduced systematically. The research progress and electrode fabrication technology of graphene electrode materials are reviewed. The characteristics of graphene materials (pore structure, electrical conductivity, etc.) are analyzed and summarized. The effect of hydrophobicity on the properties of CDI was discussed. Finally, the development of graphene electrode materials in CDI was summarized and prospected.
