NOVELTY - A copper-based metal-organic framework (HKUST-1) composite material is prepared by (S1) taking 7.3-29.3 parts talcum powder and 4-7 parts graphene oxide, adding deionized water and absolute ethanol, and ultrasonically mixing to obtain A slurry; (S2) taking 70-100 parts copper nitrate trihydrate, adding deionized water according to weight ratio of copper nitrate trihydrate and deionized water of 1:5, stirring and dissolving to obtain liquid B; (S3) dissolving 30-50 parts trimellitic acid in dimethylformamide (DMF), stirring and mixing to obtain liquid C; (S4) while stirring, adding liquid B and liquid C to the mixed liquid A, and stirring to react; and (S5) centrifugally separating to obtain HKUST-1 composite material. USE - Preparation of copper-based metal-organic framework (HKUST-1) composite material. ADVANTAGE - The method has fast reaction rate, easy production, simple reaction condition and normal pressure at normal temperature. The composite material has large micro-porous structure and improved adsorption capacity with respect to benzene.
