Reversible Electrochemical Conversion Reaction for Selective Ion Removal and Recovery

Abstract

Abstract Capacitive deionization (CDI) is a green and pollution‐free emerging technology that can be used for ions removal and recovery from water. However, the traditional electro‐adsorption process to achieve ions removal faces the challenges of non‐selectivity, low efficiency and difficult ion recovery. In recent years, the conversion reaction has attracted wide attention due to its high selectivity, reversibility and excellent desalination ability for ions removal and recovery. This concept article will focus on the connotation and representative applications of conversion reactions that can be used for ion‐selective removal and recovery and put forward the perspectives and outlooks of conversion reactions.
