Title:
VESICLE-TYPE MOF/GO COMPOSITE MATERIAL AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/206781
Kind Code:
A1
Abstract:
Disclosed in the present disclosure are a vesicle-type MOF/GO composite material and a preparation method therefor. The method comprises the following steps: carrying out oxidative stripping treatment on graphite to obtain a graphene oxide; dispersing the graphene oxide in an aqueous solution to obtain a graphene oxide dispersion; preparing an oil phase solution and an aqueous phase solution, the oil phase solution being prepared by dissolving organic ligands in a water-insoluble organic solvent, the aqueous phase solution comprising a deionized water solution in which a metal salt is dissolved and the graphene oxide dispersion; mixing the oil phase solution and the aqueous phase solution, emulsifying a mixed solution to obtain an emulsion, and heating the emulsion, so as to grow MOF crystal grains on the surface of the graphene oxide; adding a certain quantity of the organic ligands and of the metal salt again, and carrying out emulsification again; and heating an emulsion obtained after emulsification, so as to promote growth of the MOF crystal grains, thereby obtaining a vesicle-type MOF/GO composite material. The vesicle-type composite material has an excellent adsorption characteristic, and can achieve an effective selective adsorption of a specified component.
