Title:
BLOCKY METAL ORGANIC FRAMEWORK MATERIAL, AND PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/197423
Kind Code:
A1
Abstract:
A blocky metal organic framework material, and a preparation method therefor and the use thereof. The preparation method for the blocky metal organic framework material comprises: mixing raw materials comprising metal oxide nanoparticles, part of a ligand compound and water to obtain a nanoparticle dispersion liquid; mixing the nanoparticle dispersion liquid with cyclohexane, and shearing and homogenizing the resulting mixture to obtain a high internal phase emulsion; mixing the high internal phase emulsion with the residual amount of the ligand compound for reaction; and sequentially carrying out liquid nitrogen freezing and freeze drying on the reaction product, and then heating and activating same to obtain a blocky metal organic framework material. The method belongs to a high internal phase emulsion template in-situ growth method, has a short method flow and simple and convenient operation, and is easy for industrial production. The blocky metal organic framework material belongs to a hierarchical pore MOF blocky material, and the pore size thereof covers the range of both macropores and small pores, such that all characteristics of a powder material are retained and high mechanical properties are ensured. In addition, the blocky metal organic framework material can be used as a catalyst.
