Enhancing electrochemical carbon dioxide capture with supercapacitors.

ABSTRACT: Supercapacitors are emerging as energy-efficient and robust devices for electrochemical CO₂ capture. However, the impacts of electrode structure and charging protocols on CO₂ capture performance remain unclear. Therefore, this study develops structure-property-performance correlations for supercapacitor electrodes at different charging conditions. We find that electrodes with large surface areas and low oxygen functionalization generally perform best, while a combination of micro- and mesopores is important to achieve fast CO₂ capture rates. With these structural features and tunable charging protocols, YP80F activated carbon electrodes show the best CO₂ capture performance with a capture rate of 350 mmol_CO2 kg^-1 h^-1
