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.

摘要： An electrolytic device includes: an electrolytic tank; an ion exchange membrane configured to partition the electrolytic tank into a cathode chamber and an anode chamber; a catholyte supply unit configured to supply an electrolytic solution serving as a catholyte to the cathode chamber; a catholyte discharge unit configured to discharge the catholyte from the cathode chamber; an anolyte supply unit configured to supply an electrolytic solution serving as an anolyte to the anode chamber; an anolyte discharge unit configured to discharge the anolyte from the anode chamber; a cathode provided on a surface of the ion exchange membrane on the cathode chamber side; an anode provided on a surface of the ion exchange membrane on the anode chamber side; a cathode side power feeder provided in the cathode chamber and configured to supply electric power to the cathode; and an anode side power feeder provided in the anode chamber and configured to supply electric power to the anode. A pH of the catholyte is lower than a pH of the anolyte.
