ELECTROLYTIC REDUCTION APPARATUS FOR CARBON DIOXIDE

摘要

PROBLEM TO BE SOLVED: To provide an electrolytic reduction apparatus for carbon dioxide which performs electrolytic reduction of carbon dioxide at high current efficiency. SOLUTION: (1) The electrolytic reduction apparatus of carbon dioxide includes: a cathode; an anode; a power source for applying the voltage between the cathode and the anode; and an electrolytic bath performing electrolytic reduction of carbon dioxide at the cathode by electrolyzing a solution containing carbon dioxide, and comprises at least a part of a surface of the cathode of the electrolytic bath is made of conductive diamond. (2) The electrolytic reduction apparatus of carbon dioxide is provided at least a part of a surface of the anode of the electrolytic bath is made of conductive diamond. (3) The electrolytic reduction apparatus of carbon dioxide includes an ultraviolet light irradiation means for irradiating the surface of the conductive diamond of the cathode of the electrolytic bath with ultraviolet light. (4) The electrolytic bath is partitioned into an anode chamber and a cathode chamber by a diaphragm in the electrolytic reduction apparatus of carbon dioxide. COPYRIGHT: (C)2011,JPO&INPIT
