摘要
电容去离子技术是一种高效节能、绿色环保的基于电化学双电层电容理论的电吸附脱盐技术。该技术的关键和核心在于电极材料的选择。石墨烯因具有较高的比表面积、电导率以及优异的物理化学特性,被认为是一种理想的电极材料。本文从石墨烯电极材料性能设计角度出发,归纳总结了针对石墨烯材料特性(亲水性、比表面积/孔隙、导电性)的研究现状,分析存在的问题,并展望了石墨烯基电容去离子电极材料的发展前景。
Capacitive deionization is a high-efficiency,energy-saving and environmentally-friendly electro-adsorption desalination technology,which based on electrochemical double layer capacitance theory.The core part of this technology is the choice of electrode material.Graphene is considered to be an ideal electrode material due to its high theoretical specific surface area,electrical conductivity and excellent physic-chemical properties.From the designpoint of graphene electrode materials,this paper summarized the research status of graphene material characteristics(hydrophilicity,specific surface area/porosity,conductivity),analyzed the existing problems,and discussed the development prospect of graphene-based capacitive deionization electrode materials.
