Problems solved by technology

[0003] Most of the existing metal-organic framework materials have relatively complicated preparation processes, and their performance in reaction catalysis, gas storage / separation, and material selective adsorption is relatively poor, which affects the use effect of materials. Therefore, a new type of metal-organic framework material is urgently needed to change this situation

Abstract

The invention discloses a metal organic framework material and a preparation method thereof, and relates to the technical field of metal organic framework materials, the metal organic framework material comprises the following raw materials by mass: 20-40mg of ytterbium trichloride hexahydrate, 22-23mg of 2-aminoterephthalic acid and a solvent, the solvent comprises the following raw materials by volume: 1.5-3mL of N, N-dimethylformamide, 1.5-3mL of N, N-dimethylformamide, 1.5-3mL of N, N-dimethylformamide, 1.5-3mL of N, N-dimethylformamide, and the balance of water. The solvent is N, N-dimethyl formamide; and the deionized water is 0.1-0.3 mL. The preparation method comprises the following steps: mixing ytterbium trichloride hexahydrate, 2-aminoterephthalic acid, N, N-dimethylformamide and deionized water as main raw materials, carrying out a long-time heating reaction to obtain a polyhedral blocky colorless transparent crystal, washing with N, N-dimethylformamide for three times to remove unreacted reactants, and drying to obtain the ytterbium-doped polyhedral blocky colorless transparent crystal. The preparation method is simple, the prepared metal organic framework material has better performance in the aspects of reaction catalysis, gas storage / separation and substance selective adsorption, and the use effect of the material is improved.

Description

technical field [0001] The present invention relates to the technical field of metal organic framework materials, in particular to a metal organic framework material and a preparation method thereof. Background technique [0002] Metal-organic frameworks are a class of porous materials assembled by coordination between organic ligands and metal ions. MOFs have the characteristics of structural diversity, tunability of pore size, and tunability of pore environment. They are used in reaction catalysis, gas storage, etc. There are extensive researches in the fields of separation and selective adsorption of substances. [0003] Most of the existing metal-organic framework materials have relatively complex preparation processes, and their performance in reaction catalysis, gas storage / separation, and selective adsorption of substances is relatively poor, which affects the use effect of the materials. Therefore, a new type of metal-organic framework materials is urgently needed. ...
