Abstract

See full text

A device for reducing CO2 by light, including: a cathode chamber holding a first electrolyte solution that contains CO2; an anode chamber holding a second electrolyte solution; a proton conducting membrane disposed in a connecting portion between these chambers; a cathode electrode; and an anode electrode. The cathode electrode has a CO2 reduction reaction region composed of a metal or a metal compound, and the anode electrode has a photochemical reaction region composed of nitride semiconductors. The photochemical reaction region of the anode electrode has a multilayer structure of a GaN layer and an AlxGa1-xN layer containing Mg (0xGa1-xN layer is 1×1015 or more and 1×1019 or less in terms of the number of Mg atom per cm3. The anode electrode is disposed in such a manner that the AlxGa1-xN layer can be exposed to light.
