Supercapacitive Swing Adsorption of Carbon Dioxide: Current Status and Perspectives

Supercapacitive swing adsorption (SSA) is a newly discovered electrochemically driven carbon dioxide capture method using the principle of electric double‐layer capacitor, which achieves the purpose of adsorption and desorption of CO 2 by charging and discharging the supercapacitive electrodes. Based on this method, gas separation devices were designed which could adsorb CO 2 from a mixture of carbon dioxide and nitrogen, and a series of factors affecting the CO 2 adsorption capacity were explored. This review briefly introduces the SSA mechanism and the structural design of SSA modules, and analyzes the factors influencing the performance of SSA from multiple aspects, with emphasis on electrode materials, in order to find ways to improve the CO 2 adsorption capacity of SSA modules.
