Abstract

As the demand for clean water rises, the need for advanced materials and technologies intensifies. Capacitive deionization (CDI) has gained attention for water treatment including brackish water desalination, wastewater recycling, and selective resource recovery. Electrode materials play a critical role in CDI’s electrochemical performance, with MXenes, two-dimensional transition-metal carbides, and nitrides, offering a promising solution for low-energy brackish water desalination. MXenes possess excellent structural and electrochemical properties, overcoming limitations like concentration polarization in conventional CDI electrodes and reducing energy consumption. This review discusses MXenes’ properties and various preparation strategies, including intercalating agents, surface modification, heteroatom introduction, and 3D structure design. It also explores MXenes’ potential in CDI applications for seawater desalination, NH₄⁺ recovery, and ion-selective removal, emphasizing their material and environmental benefits. The review concludes by suggesting future research directions for MXenes in CDI technology.

电极材料的进展：MXenes在电容去离子技术中的作用

随着对清洁水需求的增加，对先进材料和技术的需求也在增加。电容式去离子技术（CDI）在咸淡水脱盐、废水循环利用和选择性资源回收等水处理领域受到广泛关注。电极材料在CDI的电化学性能中起着至关重要的作用，其中MXenes、二维过渡金属碳化物和氮化物为低能咸淡水淡化提供了有前途的解决方案。MXenes具有优异的结构和电化学性能，克服了传统CDI电极的浓度极化等限制，降低了能耗。本文综述了MXenes的性质和各种制备策略，包括插层剂、表面改性、杂原子引入和三维结构设计。本文还探讨了MXenes在海水淡化、NH4+回收和离子选择性去除等CDI应用中的潜力，并强调了其材料和环境效益。最后，对MXenes在CDI技术中的未来研究方向进行了展望。
