Abstract:
1. A method for reducing carbon dioxide, comprising: a step (a) of preparing an electrochemical cell, wherein the electrochemical cell comprises a working electrode, a counter electrode and a vessel, the vessel stores an electrolytic solution, the working electrode contains boron carbide, the electrolytic solution contains carbon dioxide, the working electrode is in contact with the electrolytic solution, and the counter electrode is in contact with the electrolytic solution; a step (b) of applying a voltage between the working electrode and the counter electrode with an external power supply; and a step (c) of reducing the carbon dioxide at the working electrode with the applied voltage and using the boron carbide as a catalyst, wherein the electrochemical cell further comprises a tube, one end of the tube is disposed in the electrolytic solution, and in the step (c), the carbon dioxide is supplied to the electrolytic solution through the tube.
