To demonstrate the influence of various properties of the hypothetical anthraquinone molecule employed in the system on the interplay between nucleophilicity-swing and pH-swing mechanisms, we analyze a set of equations inherent to the system. The fully reduced anthraquinone (𝐴𝑄 2-) molecule in an aqueous solution can either undergo the direct capture of CO2 through 𝐴𝑄(𝐶𝑂 2 ) 2 2-adduct formation or engage in a proton-coupled reaction:
