The invention discloses a metal and ionic liquid coupled heterogeneous catalyst as well as a preparation method and application thereof. The preparation method of the metal and ionic liquid coupling catalyst comprises the following steps: (1) mixing a carrier precursor, a metal precursor, a template agent and a solvent according to a certain mass ratio, and grinding to form a mixture; aging the mixture, performing extrusion molding, and drying; placing the dried product in a tubular furnace, and performing high-temperature carbonization in a certain amount of flowing inert atmosphere; after naturally cooling, screening a product to obtain a granular metal-carrier core-shell material; and (2) loading an ionic liquid solution onto the surface of the metal-carrier core-shell material by an equivalent-volume impregnation method, and drying to obtain the metal and ionic liquid coupling catalyst. The invention provides application of the metal and ionic liquid coupled heterogeneous catalyst in ...
