| description | The invention discloses a novel photocatalyst responding to ultraviolet, visible and near-infrared light, a preparation method of the novel photocatalyst and application of the novel photocatalyst in the field of CO2 photocatalytic conversion, commercial titanium dioxide powder serves as a precursor, titanium nitride is prepared through high-temperature nitriding treatment, a cocatalyst Ru is loaded on the titanium nitride through dipping-reduction, and the photocatalyst is obtained. The prepared photocatalyst is Ru/TiN. The photocatalyst has wide spectral response, and can efficiently catalyze carbon dioxide to be selectively converted into carbon monoxide under the irradiation of ultraviolet-visible-near infrared light. The photocatalyst is simple in preparation process and has a wide application prospect in the aspect of preparing renewable energy sources by utilizing solar energy and the like.
