Metal organic framework material HP-UiO-66-F4 as well as room-temperature rapid preparation method and application thereof

Abstract

The invention relates to a layered mesoporous metal organic framework material HP-UiO-66-F4 and a room-temperature rapid preparation method and application thereof, and the preparation method comprises the following steps: (1) respectively dissolving a zirconium source and an organic ligand in deionized water, adding a proper amount of acetic acid, uniformly mixing, stirring at room temperature, centrifuging, and discarding supernate to obtain an intermediate product; and (2) carrying out vacuum drying on the intermediate product obtained in the step (1) to obtain the layered mesoporous metal organic framework material HP-UiO-66-F4. Compared with the prior art, the method has the advantages that toxic organic solvents such as N, N-dimethylformamide in a traditional solvothermal method are not used, the HP-UiO-66-F4 can be synthesized only by stirring in the deionized water at room temperature and drying, the condition is mild, the yield is higher, the synthesis time is greatly shortened, the product purity is extremely high, the step of activating the product can be omitted, and the method is suitable for industrial production. The large-scale synthesis of the metal organic framework material becomes great possible; immobilization of dextranase is successfully achieved, and the method can be applied to immobilization of large-size enzyme.
