Abstract

The invention discloses a cuprous oxide (Cu20)-metal organic frame (MOFs) composite material and a preparation method thereof. The preparation method of the cuprous oxide-mental organic frame composite material includes the steps of coating silicon dioxide (SiO2) on the surface of the cuprous oxide nanoparticles to protect the same, then coating the CU-20 and the SiO2 inside a ZIF-8 (zeolitic imidazolate framework) crystal, and finally selectively etching to remove the SiO2 so as to obtain the Cu20 and ZIF-8 in a sodium hydroxide solution. The cuprous oxide-metal organic frame composite material and the preparation method thereof have the advantages that with a simple chemical synthesis process to wrapping the unstable cuprous oxide nanoparticles into the MOFs crystal and obtain a sample of the Cu20 and ZIF-8 composite material, oxidation resistance of the material is significantly improved compared with the cuprous oxide nanoparticles, and the composite material can be applied to suchfield as catalysis; the preparation method thereof has the advantages of being simple and controllable, mild in conditions, environment-friendly, low in energy consumption and cost, and suitable forindustrial production.

Description

technical field

[0001] The invention belongs to the field of preparation of MOFs-based composite materials, in particular to a Cu 2 O-MOFs composite material and its preparation method. Background technique

[0002] Metal-organic frameworks (MOFs), also called porous coordination polymers (PCPs), are a class of periodic polymers formed by self-assembly of metal ions or metal cluster units and organic ligands through coordination. Porous crystalline material with multidimensional network structure. As an emerging porous material, it not only has a highly developed pore structure and super high specific surface area, but also has structural diversity and flexibility in synthesis. Therefore, it is widely used in gas adsorption, storage and separation, optoelectronic materials, catalysis and other fields.

[0003] At present, there are many methods for the preparation of composite materials of metal nanoparticles or metal oxide nanoparticles and MOFs, but the preparation meth...
