A preparation method and application of a hydrogenation catalyst. The invention relates to a titanium ore catalyst, which is applied to CO or CO2 hydrogenation to prepare ethylene, propylene and butene. By introducing nitrogen element and modifying GaFeO 3 , the adsorption and dissociation of CO are promoted to a large extent, and the hydrogenation reaction shows good selectivity of light olefins. have potential economic value. |
