Abstract
Methods and systems for capture of carbon dioxide and electrochemical conversion of the captured carbon dioxide to organic products are disclosed. A method may include, but is not limited to, steps (A) to (C). Step (A) may introduce a solvent to a first compartment of an electrochemical cell. Step (B) may capture carbon dioxide with at least one of guanidine, a guanidine derivative, pyrimidine, or a pyrimidine derivative to form a carbamic zwitterion. Step (C) may apply an electrical potential between an anode and a cathode sufficient for the cathode to reduce the carbamic zwitterion to a product mixture.

A method for electrochemical conversion of carbon dioxide, comprising:
- (A) introducing a solvent to a first compartment of an electrochemical cell, the first compartment including an anode, the electrochemical cell including a second compartment containing a cathode;
- (B) capturing carbon dioxide with at least one of 1,1,3,3-tetramethylguanidine, 1,5,7-triazabicyclo[4.4.0]dec-5-ene, 7-methyl-1,5,7triazabicyclo[4.4.0]dec-5-ene, 1,8-diazabicyclo[5.4.0]undec-7-ene, 1,5-diazabicyclo[4.3.0]non-5-ene, and 1,4,5,6-tetrahydropyrimidine to form a carbamic zwitterion;
- (C) introducing the carbamic zwitterion to the second compartment via at least one of (i) forming the carbamic zwitterion in the second compartment or (ii) delivering the carbamic zwitterion to the second compartment;
- and
- (D) applying an electrical potential between the anode and the cathode sufficient for the cathode to reduce the carbamic zwitterion to a product mixture, the product mixture including an organic product derived in part from the carbon dioxide.
