METHOD FOR REDUCING CARBON DIOXIDE

摘要

Disclosed is a method for reducing carbon dioxide comprising a step (a) and a step (b). Step (a): preparing an electrochemical cell. Here, the electrochemical cell comprises a working electrode (21), counter electrode (23), and tank (28). The tank (28) stores an electrolyte (27). The working electrode (21) contains at least one boride selected from a group formed from vanadium borides, niobium borides, tantalum borides, hafnium borides, tungsten borides, and iron borides. The electrolyte (27) contains carbon dioxide. The working electrode (21) and the counter electrode (23) are in contact with the electrolyte (27). Step (b): a negative voltage and a positive voltage are applied to the working electrode (21) and the counter electrode (23), respectively, and the carbon dioxide is reduced.
