PROBLEM TO BE SOLVED: To provide a new carbon dioxide photoreduction catalyst having high reduction efficiency of carbon dioxide, and further to provide a method of producing a carbon dioxide photoreduction catalyst having high reduction efficiency of carbon dioxide without using an expensive noble metal.SOLUTION: There is provided a carbon dioxide photoreduction catalyst containing a titanium oxide on which a vanadium oxide is supported. Further, there is provided a method for producing a carbon dioxide photoreduction catalyst in which, while bringing a titanium oxide into contact with a vanadium-containing solution prepared by dissolving a raw material for a vanadium oxide in a solvent, a vanadium oxide is supported on the titanium oxide by irradiating light of a wavelength having an energy equal or more to that of a bandgap energy of the vanadium oxide.SELECTED DRAWING: None |
