Dual Salt Cation-Swing Process for Electrochemical CO₂ Separation.

ABSTRACT: Electrochemical CO₂ separations, which use electricity rather than thermal energy to reverse sorption of CO₂ from concentrated point sources or air, are emerging as compelling alternatives to conventional approaches given their isothermal, ambient operating conditions, and ability to integrate with renewable energy inputs. Despite several electrochemical approaches proposed in previous studies, further explorations of new electrochemical CO₂ separation methods are crucial to widen choices for different emissions sources. Herein, we report an electrochemical cation-swing process that is able to reversibly modulate the CO₂ loading on liquid amine sorbents in dimethyl sulfoxide (DMSO) solvent. The process exploits a reversible carbamic acid-to-carba
