Abstract

Abstract Capacitive deionization is an efficient and cost-effective technology for ion removal from brackish water. Here, we demonstrate a sulfonate-functionalized covalent organic framework as a novel faradaic cathode material for capacitive deionization applications. Due to its orderly arranged adsorption units in the covalent organic framework, the resulting covalent organic framework demonstrates a superior sodium cations removal capacity of 19.56 mg g−1 and a maximum desalination rate of 3.15 mg g−1 s−1 in a 500 ppm NaCl solution at 1.2 V.
