Carbon dioxide and water are mixed with an organometallic complex represented by general formula (1) below n n nwhere R 1 , R 2 , R 3 , R 4 , R 5 , and R 6 independently represent a hydrogen atom or a lower alkyl group, M represents an element that can be coordinated to the benzene ring, X 1 and X 2 represent nitrogen-containing ligands, X 3 represents a hydrogen atom, a carboxylic acid residue, or H 2 O, X 1 and X 2 may be bonded to each other, Y represents an anion species, K represents a valency of a cation species, L represents a valency of an anion species, K and L independently represent 1 or 2, and K, m, L, and n are related to one another by K×m=L×n. This makes it possible to directly reduce carbon dioxide in water. |
