| description | The invention discloses a polyacid zeolite imidazate framework loaded monatomic catalyst as well as a preparation method and application thereof, and belongs to the technical field of catalysts, the preparation method of the catalyst comprises the following steps: (1) preparing a zeolite imidazate framework material; (2) mixing and stirring the dried zeolite imidazate framework material and metal salt in a solvent; adding heteropolyacid, controlling the pH value of the system to be 5-7, and carrying out solvothermal reaction at 80-120 DEG C; after the reaction is finished, cooling and centrifugally separating to obtain a precipitate; and (3) calcining the precipitate to obtain the polyacid zeolite imidazate framework loaded monatomic catalyst. The polyacid zeolite imidazate framework loaded monatomic catalyst prepared by the method is high in catalytic activity, high in selectivity and good in cycling stability, and has a relatively good application prospect in an esterification reaction of levulinic acid.
