The invention discloses a preparation method of a modified zeolite-like imidazole framework material, and an application of the material in a carbon dioxide hydrogenation reaction. The method comprises the following steps: preparing a zeolite-like imidazole framework material ZIFs through a solvothermal technology, loading the zeolite-like imidazole framework material ZIFs on a carrier, and applying the loaded zeolite-like imidazole framework material ZIFs to the carbon dioxide hydrogenation reaction. The zeolite-like imidazole framework material in the carbon dioxide hydrogenation reaction simply and effectively improves the catalysis activity, and obviously improves the methanol selectivity under mild reaction conditions; and the method has the advantages of low preparation cost, and good economic, effective and universal property, and also has the advantages of no corrosion of devices, environmentally-friendly process, effective improvement of the production conditions, reduction of the production cost, an
