Direct air capture (DAC) aims to remove CO<sub>2</sub> directly from the atmosphere. In this study, we have demonstrated proof-of-concept of a DAC process combining CO<sub>2</sub> adsorption in a packed bed of amine-functionalized anion exchange resins (AERs) with a pH swing regeneration using an electrochemical cell (EC). The resin bed was regenerated using the alkaline solution produced in the cathodic compartment of the EC, while high purity CO<sub>2</sub> (>95%) was desorbed in the acidifyin ...[more]
