<p>PURPOSE: A reduction method of carbon dioxide using solar rays, and an apparatus using the same are provided to increase the reduction efficiency of the carbon dioxide by adding water additionally to hydrogen and the carbon dioxide. CONSTITUTION: A reduction method of carbon dioxide using solar rays comprises the following steps. A complex catalyst containing a metal(200), a metal compound(100), and a photosensitizer(300) is loaded into a reactor. The gas with hydrogen gas and carbon dioxide gas is inserted to the reactor to react the hydrogen gas and the carbon dioxide gas under irradiation. The metal compound is selected from the group consisting of a metal oxide, a metal carbide, a metal oxycarbide, and a combination thereof. The gas, inserted into the reactor containing the hydrogen gas and the carbon dioxide gas, additionally contains water(H2O).</p> |
