Problems solved by technology
[0003] However, for a long time, one of the reasons restricting the application of metal-organic frameworks (MOFs) is their poor chemical stability. Therefore, how to choose organic ligands and metal ions, and what process methods to use have become research hotspots and difficulties in the construction of stable MOFs.

Abstract
The invention discloses a preparation method of a zirconium-based metal organic framework material. The preparation method comprises the following steps: firstly, mixing an organic ligand H4BCPIA and a metal compound ZrCl4 according to a set ratio, wherein a molar ratio of the organic ligand H4BCPIA to the metal compound ZrCl4 is 1: 2; then adding a certain amount of N,N-dimethylformamide and formic acid into a mixed solution obtained in the previous step; and placing the obtained mixed solution in a drying oven for a reaction so as to finally obtain the metal organic framework material with a crystal structure. The method has the advantages of simple synthesis process, high crystal purity, high porosity, large specific surface area, novel structure and reusability.
Description
technical field [0001] The invention relates to the technical field of crystalline materials, in particular to a preparation method of a zirconium-based metal organic framework material. Background technique [0002] At present, as a new type of organic-inorganic hybrid porous materials, metal-organic frameworks (metal-organic frameworks, MOFs) have the advantages of extremely high specific surface area, tunable pore size, adjustable pore size and diversity of framework components. Adsorption and storage, sensing, heterogeneous catalysis, proton conduction, etc. have great potential. Such materials are generally constructed by metal ions or metal clusters and organic ligands through coordination bonds. [0003] However, for a long time, one of the reasons restricting the application of metal-organic frameworks (MOFs) is their poor chemical stability. Therefore, how to choose organic ligands and metal ions, as well as what process methods to use have become research hotspots ...
