Carbon dioxide reduction device, and porous electrode

A carbon dioxide reduction device comprising:

• a first electrode;
• at least any one of an electrolyte solution and an ion conducting membrane;
• and
• a second electrode,
• wherein the first electrode is a porous electrode comprising a porous carbon, and the porous carbon comprises at least one type of metal-nonmetal element bond represented by M-R, in which M represents a metal element of Groups 4 to 15, and R represents a nonmetal element wherein the nonmetal element represented by R is carbon element constituting the porous carbon, or a nonmetal element of Groups 14 to 16, other than the carbon element, linked to the carbon element constituting the porous carbon via a covalent bond, wherein when R is a nitrogen, the nitrogen is derived from an organic compound comprising R selected from organic polymers having complex aromatic ring;
• and
• the carbon dioxide reduction device further comprising an inlet port that is configurated to introduce carbon dioxide to the first electrode,
• wherein the M-R is at least one selected from the group consisting of Sb—C, Bi—C, Sn—C, Pb—C, Ni—C, Ru—C, Co—C, Rh—C, Cu—C, Ag—C, In—N, Pb—N, Sb—N, Bi—N, Ni—N, Ru—N, Co—N, Rh—N, Cu—N, Ag—N, Ni—S, Ru—S, Co—S, Rh—S, Cu—S, Ag—S, Ni—O, Ru—O, Co—O, Rh—O, Cu—O, Ag—O, Mn—C, Fe—C, Zn—C, Nb—C, Mo—C, Zn—N, Nb—N, Mo—N, Mn—S, Fe—S, Zn—S, Nb—S, Mo—S, Mn—O, Fe—O, Zn—O, Nb—O, and Mo—O.
