摘要： This carbon dioxide absorption and reduction solution includes 0.01-100 mM of a metal complex in a mixed solvent of water and a water soluble solvent, wherein: the metal complex includes a central metal atom which is any one of rhenium, manganese, or iron and a ligand which coordinates with the central metal atom; the ligand includes two or more carbonyl groups and two or more nitrogen atom-containing heterocycles; and at least one of the two or more nitrogen atom-containing heterocycles has at least one substituent including a carboxy group or a hydroxy group. If the central metal atom of the metal complex is ruthenium, the nitrogen atom-containing heterocycles do not have to include a carboxy group or a hydroxy group.
