Abstract

Methods and systems for electrochemical reduction of carbon dioxide using advanced aromatic amine heterocyclic catalysts are disclosed. A method for electrochemical reduction of carbon dioxide may include, but is not limited to, steps (A) to (C). Step (A) may introduce water to a first compartment of an electrochemical cell. The first compartment may include an anode. Step (B) may introduce carbon dioxide to a second compartment of the electrochemical cell. The second compartment may include a solution of an electrolyte, a catalyst, and a cathode. The catalyst may include at least two aromatic amine heterocycles that are at least one of (a) fused or (b) configured to become electronically conjugated upon one electron reduction. Step (C) may apply an electrical potential between the anode and the cathode in the electrochemical cell sufficient for the cathode to reduce the carbon dioxide to a product mixture.
