Impacts of Quinone Structure on Trade-Offs Between Redox Potential and CO<sub>2</sub> Binding Strength. [PDF]
ChemphyschemQuinones are well‐studied and promising candidates for redox‐active sorbents in electrochemical CO2 capture and storage (ECCS). Unfortunately, reactivity with O2 is a persisting issue in the use of quinones. While attempts have been made to tune the redox‐potentials of quinones to avoid this, quinones which are more tolerant to the presence of O2, are ...
