The present invention relates to a ruthenium/copper chromium oxide junction structure photothermal catalyst for efficiently converting carbon dioxide into methane, and a manufacturing method thereof, wherein the ruthenium-copper chromium oxide junction structure photothermal catalyst of the present invention is a solar condensed solar catalyst without additional heat supply The methane generation efficiency under light irradiation is 10,000 times higher than that of pure ruthenium, and 5 times higher than the conventionally reported ruthenium-silicon nanowire junction structure system, and a photothermal catalyst having excellent efficiency can be provided. |
