Carbon dioxide reduction and fixation system, carbon dioxide reduction and fixation method, and method for producing useful carbon resources

摘要

The carbon dioxide reduction immobilization system (1) includes a reaction section (1A) having a cathode (11) and an anode (12) disposed with an electrolyte (13) interposed therebetween, an anode (12) and a cathode (11 ) And an external power source (power source unit) (17) for applying a voltage between the cathode and the anode (12), electrons are generated by an oxidation reaction, and gas phase carbon dioxide is reduced by a reduction reaction at the cathode (11). Cations or anions are transported through the electrolyte (13) so as to be fixed and compensate for the bias of charge between the electrodes accompanying the oxidation reaction or the reduction reaction.
