Catalysts for Carbon Dioxide Conversion

摘要

The disclosure relates generally to improved methods for the reduction of carbon dioxide. The disclosure relates more specifically to catalytic methods for electrochemical reduction of carbon dioxide that can be operated at commercially viable voltages and at low overpotentials. The disclosure uses a transition metal dichalcogenide and helper catalyst in contact within the cell.

主权项

1. A method of electrochemically reducing carbon dioxide in an electrochemical cell having a cathode comprising at least one transition metal dichalcogenide, an electrolyte in contact with the cathode, and an anode, the method comprising
contacting the carbon dioxide with the at least one transition metal dichalcogenide of the cathode of the electrochemical cell, the electrolyte comprising at least one helper catalyst, each helper catalyst comprising at least one positively charged nitrogen, sulfur, or phosphorus group and applying a potential to the electrochemical cell sufficient to reduce the carbon dioxide.
