Abstract
In a method for generating formic acid by reducing carbon dioxide, a formic acid generation apparatus is prepared. The apparatus includes: a cathode container for storing a first electrolyte solution containing carbon dioxide; an anode container for storing a second electrolyte solution; a solid electrolyte membrane sandwiched between the cathode and anode containers; a cathode electrode provided in the cathode container in contact with the first electrolyte solution, the cathode electrode having a gallium oxide region on a surface thereof; an anode electrode provided in the anode container in contact with the second electrolyte solution; and an external power supply for applying a negative voltage and a positive voltage to the cathode electrode and the anode electrode, respectively. A negative voltage and a positive voltage are applied to the cathode electrode and the anode electrode, respectively, using the external power supply to generate formic acid on the cathode electrode.
