Abstract

The chemistry of the electrocatalytic reduction of CO ₂ using nitrogen containing heteroaromatics is further explored by the direct comparison of imidazole and pyridine catalyzed CO ₂ reduction at illuminated iron pyrite electrodes. The mechanism of imidazole based catalysis of CO ₂ reduction is investigated by analyzing the catalytic activity of a series of imidazole derivatives using cyclic voltammetry. While similar product distributions are obtained for both imidazole and pyridine, the imidazole catalyzed reduction of CO ₂ likely proceeds via a very different mechanism involving the C2 carbon of the imidazole ring.
