요약

A method for reducing carbon dioxide is provided. In the present method, used is an anode electrode comprises a stacked structure of a photoelectric conversion layer, a metal layer, and an InxGa1-xN layer (where 01). The InxGa1-xN layer is of i-type or n-type. The metal layer is interposed between the photoelectric conversion layer and the InxGa1-xN layer. When irradiating the anode electrode with light, a first light part included in the light is absorbed by the InxGa1-xN layer and a second light part included in the light travels through the InxGa1-xN layer. The second light part is absorbed by the photoelectric conversion layer to generate electric power in the photoelectric conversion layer. The second light part has a longer wavelength than the first light part. The carbon dioxide contained in the first electrolyte solution is reduced on the cathode electrode.

1. A method for reducing carbon dioxide, comprising: (a) preparing a carbon dioxide reduction device comprising: a cathode chamber storing a first electrolyte solution containing carbon dioxide;an anode chamber storing a second electrolyte solution;a proton exchange membrane interposed between the cathode chamber and the anode chamber;a cathode electrode that is in contact with the first electrolyte solution and that comprises a metal or a metal compound on the surface thereof; andan anode electrode that is in contact with the second electrolyte solution, whereinthe carbon dioxide reduction device does not comprise an external power supply;the anode electrode comprises a stacked structure of a photoelectric conversion layer, a metal layer, and an InxGa1-xN layer (where 01);the InxGa1-xN layer is of i-type or n-type;the metal layer is interposed between the photoelectric conversion layer and the InxGa1-xN layer;the metal layer covers a part of the photoelectric conversion layer;the photoelectric conversion layer comprises a first p-type semiconductor layer and a first n-type semiconductor layer;the first p-type semiconductor layer is electrically connected to the InxGa1-xN layer; andthe first n-type semiconductor layer is electrically connected to the cathode electrode; and(b) irradiating the anode electrode with light, wherein in the step (b),a first light part included in the light is absorbed by the InxGa1-xN layer;a second light part included in the light travels through the InxGa1-xN layer;the second light part is absorbed by the photoelectric conversion layer to generate electric power in the photoelectric conversion layer;the second light part has a longer wavelength than the first light part; andthe carbon dioxide contained in the first electrolyte solution is reduced on the cathode electrode.
