  • CARBON DIOXIDE ABSORPTION AND REDUCTION SOLUTION, CARBON DIOXIDE ABSORPTION AND REDUCTION DEVICE, AND CARBON DIOXIDE ABSORPTION AND REDUCTION METHOD
    Publication number: 20240293771
    Abstract: A carbon dioxide absorption and reduction solution contains 0.01 to 100 mM of a metal complex in a mixed solvent of water and a water-soluble solvent. The metal complex contains: a central metal which is any of rhenium, manganese, or iron; and a ligand which coordinates to the central metal. The ligand includes two or more carbonyl groups and two or more nitrogen-containing heterocycles, and at least one of the two or more nitrogen-containing heterocycles has at least one substituent including a carboxy group or a hydroxy group. When the central metal of the metal complex is ruthenium, the nitrogen-containing heterocycles May not have a carboxy group or a hydroxy group.
