电容去离子用功能化电极吸附材料的设计与构建

电容去离子(CDI)是近年来新兴的一种脱盐技术,由于其具有节能环保、实用性强等优势而倍受青睐。作为该技术核心的电极吸附材料,应具有高比表面积、良好导电性、亲水性、适宜孔隙结构、优异的稳定性等特点。这将有效保障该CDI器件不仅具有高CDI脱盐效率,而且拥有更强的循环稳定性。本文结合我们前期研究工作,针对吸附电极的制备、结构与性能构效关系的差异,综述了近年来多种功能化电极材料在CDI技术应用中的最新进展。

Design and fabrication of functionalized adsorption materials for capacitive deionization

Capacitive deionization (CDI) is currently widely applicable one of the desalination technologies owing to its advantages, such as energy efficiency, environmental protection and high practicability, etc. Electrode materials, as core of this technology, should have high specific surface area, better conductivity, good hydrophilicity, proper porous structure, excellent stability and so on. These properties would efficiently not only enhance desalination efficiency of CDI devices, but also keep excellent cycling stability, even in the complex systems. In the light of difference in preparation, structure-activity relationship of electrodes, the recent advances in the application of various functional electrode materials have been reviewed, combining with our previous work.
