Abstract: An electroactive species includes a quinone core structure and at least one stabilizing group covalently bound thereto. The stabilizing group includes a cationic group, a hydrogen bond donor, or a combination thereof. The electroactive species has an oxidized state and at least one reduced state capable of bonding with a Lewis acid gas to form an anion adduct. Methods for separating a Lewis acid gas from a fluid mixture, electrochemical cells, and gas separation systems are also provided.

Abstract: A method for separating a Lewis acid gas from a fluid mixture, comprising contacting the fluid mixture with a reduced electroactive species; a non-aqueous electrolyte; and a stabilizing additive to form an anion adduct between the Lewis acid gas and the reduced electroactive species, wherein the electroactive species comprises an oxidized state, and at least one reduced state that bonds with the Lewis acid gas to form the anion adduct, wherein the stabilizing additive comprises a cationic Lewis acid, a hydrogen-bond donor, or a combination thereof, and the stabilizing additive is present in an effective amount to kinetically favor the forming of the anion adduct from the reduced electroactive species and thermodynamically favor the forming of the anion adduct in the thermodynamic equilibrium between the anion adduct and the reduced electroactive species.

Abstract: A composite includes a nonwoven carbon nanotube mat and an electroactive species disposed on the nonwoven carbon nanotube mat, wherein the electroactive species is capable of bonding with a target gas when the electroactive species is in a reduced state and releasing the target gas when the electroactive species is in an oxidized state. Electrode assemblies, electrochemical cells, and gas separation systems including the composite are also described herein.
