Upon cycling, however, a loss of carbon dioxide adsorption is seen which could be due to an irreversible reaction between anthraquinone and CO2. Our facile synthesis method lends itself to the preparation of a large family of sorbents for electrochemical CO2 capture. Indeed, the porous carbon support and the redox-active molecules can readily be varied to prepare a large family of materials. Research beyond the scope of this study into the carbon-capture mechanism within these systems is ongoing. Furthermore, more work to investigate the efficiency of electrochemical capture systems in more realistic conditions, in lower concentrations of CO2, and in the presence of oxygen and moisture needs to be carried out.
