Abstract

Capacitive deionization (CDI) is an efficient and cost-effective technology for ion removal from brackish water. Here, we demonstrate a sulfonate-functionalized covalent organic framework (COF) as a novel faradaic cathode material for CDI applications. Due to its orderly arranged adsorption units in the COF, the resulting COF demonstrate 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.

用于电容式去离子的磺酸盐官能化共价有机框架

电容式去离子（CDI）是一种从苦咸水中去除离子的高效且经济的技术。在这里，我们展示了一种磺酸盐功能化共价有机框架（COF），作为一种新型法拉第阴极材料用于 CDI 应用。由于 COF 中的吸附单元排列有序，因此在 500 ppm 的 NaCl 溶液中，COF 的钠离子去除能力高达 19.56 mg g-1，最大脱盐率为 3.15 mg g-1 s-1。

期刊介绍： The Bulletin of the Chemical Society of Japan (BCSJ) is devoted to the publication of scientific research papers in the fields of Theoretical and Physical Chemistry, Analytical and Inorganic Chemistry, Organic and Biological Chemistry, and Applied and Materials Chemistry. BCSJ appears as a monthly journal online and in advance with three kinds of papers (Accounts, Articles, and Short Articles) describing original research. The purpose of BCSJ is to select and publish the most important papers with the broadest significance to the chemistry community in general. The Chemical Society of Japan hopes all visitors will notice the usefulness of our journal and the abundance of topics, and welcomes more submissions from scientists all over the world.
