An alternative approach that can address these issues is to immobilize quinones in a solidstate electrode in a battery-like architecture. Initial approaches in this direction used solid-state quinone electrodes to electrochemically capture carbon dioxide, yet they suffered from significant instability due to quinone dissolution into the organic electrolytes used, leading to a capacity loss when cycling. Research by Voskian et al. addressed this challenge by developing electrodes comprised of poly(anthraquinone) and carbon nanotubes and demonstrated electrochemical CO2 capture at a variety of CO2 concentrations. Notably, the poly(anthraquinone) electrodes could be stacked, allowing higher CO2 adsorption capacities to be achieved. However, a limitation of this approach is the complex synthesis of the polymer electrode, which requires expensive coupling agents. This motivates the need for the development of new classes of inexpensive, easily synthesized quinone-functionalized electrodes that are broadly tunable for electrochemical CO2 capture.
