A selective hydrogenation catalyst for alkadiene. A carrier of the catalyst is a carboxyl-functionalized step hole FZIF-8, an active component is palladium, and the content of the active component ranges from 0.1% to 10% on the basis of the total weight of the carrier of the catalyst. A method for preparing the catalyst comprises: mixing and crystallizing raw materials, and conducting extraction and drying to obtain an FZIF-8 carrier, and making palladium immerse the carrier, so as to obtain the catalyst. Uses of the catalyst in a selective hydrogenation reaction for alkadiene are also provided. A step hole structure is formed in the carrier of the catalyst, so that carboxyl groups have accessibility, and the active components and the carboxyl groups can mutually interact; the carboxyl groups are contained in the carrier of the catalyst, and can anchor the active components, so that high dispersion of the active components is achieved, agglomeration and drain of the active components during the reaction are prevented, and the catalyst has high activity. |
