Description

technical field [0001] The present application relates to the technical field of catalysts, in particular to a magnetic catalyst and its preparation method and application. Background technique [0002] Catalytic hydrogenation of furfural to prepare furfuryl alcohol is an important chemical production process. At present, the catalysts used for hydrogenation of furfural are mainly supported copper-based catalysts. However, the use of such catalysts has problems such as the difficulty in separating the catalyst from the reactants, and the low degree of catalyst recovery and reuse. Therefore, magnetic catalysts have important practical significance. [0003] However, taking the magnetic catalyst with Fe3O4 as an example, this type of magnetic catalyst usually needs to wrap Fe3O4 inside a protective layer to maintain its stability, but because this type of magnetic catalyst is coated Therefore, it will affect the recycling performance and catalytic performance of the catalyst....
