Preparation method of graphene/metal organic frame aerogel adsorbing/catalyzing material

The invention relates to a preparation method of a graphene/metal organic frame aerogel adsorbing/catalyzing material. The preparation method comprises the following steps: mixing graphene oxide and a metal organic frame crystal according to the mass ratio of 1:(0.2-5) to prepare a reaction mixed liquid system, then adding a crosslinking agent, heating to 150 to 200 DEG C, performing heat-preserving reaction for 2 to 24 hours, cooling, separating out a product, washing and freeze-drying to prepare the graphene/metal organic frame aerogel adsorbing/catalyzing material. The graphene/metal organic frame aerogel adsorbing/catalyzing material prepared by the method is three-dimensional porous net-like structure aerogel, has the characteristics of high porosity, large specific surface area, excellent mechanical performance and the like, has double capabilities of adsorbing and catalytically degrading pollutants in water, and has the characteristics of high removal efficiency, high reusability, simplicity in separat
