Abstract: Methods and systems related to oxocarbon electrolyzers are disclosed herein. A disclosed system includes an oxocarbon electrolysis reactor with an anode area with an oxidation substrate, cathode area with an oxocarbon species as a reduction substrate, and an electroneutral separator separating the anode area and the cathode area while allowing ionic migration between the anode area and cathode area. The electroneutral separator may be a porous electroneutral separator. The oxocarbon electrolyzer may also include a conductive electrolyte applied to the separator. Ionic migration between the anode area and the cathode area may be accomplished via the conductive electrolyte in the porous electroneutral separator.

Abstract: A solid-electrolyte electrolytic device may be excellent in operation rate and have device life without stopping a CO2 reduction reaction. A solid-electrolyte electrolytic device may include: a cathode that performs a reduction reaction; an anode that constitutes one pair of electrodes together with the cathode; an electrolytic solution that is in contact with the anode and supports an oxidation-reduction reaction; a solid electrolyte that is disposed between the cathode and the anode; and a refresh unit that supplies a recovery liquid for diluting or replacing the electrolytic solution to the anode to remove a salt precipitated between the cathode and the solid electrolyte, the recovery liquid being a solution with a lower concentration of a cation identical to a cation included in the salt than the electrolytic solution.

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.
