电化学驱动盐离子捕获的金属基复合材料研究进展

Review on metal-based composites for electrochemically driven salt-ions capture

为了缓解淡水危机问题,选择一种高效、环保、低耗的海水淡化技术至关重要。电容去离子技术作为一种新兴的水处理技术,电极材料是其中的核心要素之一。金属基材料能够通过法拉第反应结合盐离子,从而提升电吸附性能。介绍了典型的镍基、铁基、锰基电极材料在电容去离子中的应用以及相应提升性能的手段,以期为后续高效电极材料的设计应用提供参考。

In order to alleviate the problem of fresh water crisis,it is quite important to choose an efficient,environmentally friendly and low-consumption desalination technology.Capacitive deionization(CDI)is a new water treatment technology,and electrode material is one of the core elements.Metal-based materials can bind salt ions through the Faradic reaction to improve the electro-adsorption performance.This article introduced the application of typical nickel-based,iron-based and manganese-based electrode materials in CDI and the corresponding means to improve the performance,which provided a reference for the subsequent design and application of highly efficient electrode materials.
