The invention discloses a metal organic framework material/functional ionic liquid composite material as well as preparation and application thereof, and belongs to the technical field of light industry and chemical engineering materials. As a functional ionic liquid is synthesized and loaded on a meal organic framework material by using a 'ship-in-a-bottle synthesis' method, the circulation use efficiency of the ionic liquid can be effectively improved, and the use amount of the ionic liquid can be reduced; and due to the diversity of the metal organic framework material, a series of different metal organic framework materials/functional ionic liquid composite materials can be synthesized. The metal organic framework material/functional ionic liquid composite material disclosed by the invention can be applied to gasoline catalytic oxidation desulfurization, and the purposes of improving the catalytic property of a system, reducing the amount of the ionic liquid and facilitating product separation and catalyst recycling can be achieved. The composite material disclosed by the invention can be used as a catalyst for adsorbing, oxidizing, extracting and removing sulfur-containing substances in gasoline, and is gentle in reaction condition, good in desulfurization effect and easy in catalyst recycling.
