ABSTRACT
A plot of redox potentials vs. the number of electrons transferred in the above reactions is presented in Figure 1, indicating that multielectron reductions are energetically favored.^ Since these reactions require very much less energy per electron transferred than the direct monoelectronic reduction of carbon dioxide to its radical anion CO2", i.e., -2 .1 V vs. SCE,^ there exists considerable interest to apply multielectron transfer to the reduction of carbon dioxide.
