We present two novel experimental techniques designed to quantify the contributions of nucleophilicity-swing and pH-swing mechanisms carbon capture in electrochemical aqueous quinone-based CO2 process. Through thermodynamic analysis, we elucidate intricate interplay between these mechanisms, emphasize critical role understanding this material discovery cycle for applications. This insight prompts development innovative situ techniques. The first technique capitalizes on discernible voltage...
We report an electrochemical cell for CO2 capture based on pH swing cycles driven through proton-coupled electron transfer of a newly developed phenazine, 2,2'-(phenazine-1,8-diyl)bis(ethane-1-sulfonate) (1,8-ESP), which exhibits high aqueous solubility, > 1.35 M, over range 0.00–14.90. The system operates with capacity 0.86–1.41 mol/L, low energetic cost 36.4–55.2 kJ/mol, and extremely fade rate < 0.01%/day, depending organic concentration. charge-discharge cycle provides electrical...
The development of devices capable capturing and sequestering carbon dioxide emissions directly from air or at point sources is motivated by mitigating climate change. Electrochemically driven capture release ambient temperature pressure through the formation complexes with organic redox active molecules [1,2] via pH swing caused proton-coupled electron transfer during molecular events [3,4] has shown promising results for in terms energy cost, scalability safety compared to state art amine...
