Abstract

A functional nanometer material/metal-organic framework composite is disclosed. The functional nanometer material is ferritin, carbon nano tubes or glucose oxidase. The metal-organic framework is HKUST-1. The mole ratio of the functional nanometer material to the metal-organic framework is 20-100:1. The functional nanometer material/metal-organic framework composite is provided. The functional nanometer material is uniformly dispersed in a copper hydroxide nanowire layer to enhance dispersity of the functional nanometer material, so that active sites on surfaces of the functional nanometer material are completely exposed, and the application scope of a metal-organic framework structure is broadened.

Description

technical field [0001] The invention relates to a preparation method of a composite material, in particular to a functional nanometer material / metal organic framework compound and a preparation method thereof. Background technique [0002] Metal Organic Frameworks (MOFs) is a class of crystalline materials with periodic network topology, which is an inorganic-organic composite material formed by the connection of metal ions and organic ligands through coordination bonds. , the metal is the vertex, and the organic ligand is the bridge chain. Because metal-organic frameworks have both inorganic and organic components, this type of compound has both the properties of inorganic materials and the properties of organic materials. [0003] The synthesis methods of metal-organic frameworks mainly include hydrothermal method (solvothermal method), microwave-assisted hydrothermal method (solvothermal method), layered diffusion method or stirring synthesis method, etc. [0004] The h...
