Embodiment

[0021] A kind of preparation method of the 2-methylimidazole zinc complex with hierarchical pore structure, the steps are as follows:

[0022] 1) Preparation of aligned soluble polystyrene microsphere templates

[0023] 54mL styrene, 6mL methacrylic acid and 450mL H 2 O was mixed uniformly at 80°C to obtain solution c; 0.6g potassium persulfate was dissolved in 30mL H 2 Solution d was prepared in O; solution d was added to solution c, and continued to stir for 24 hours. After centrifugation, the white solid obtained was washed three times with water and ethanol respectively, and then washed with H 2 The mixed solution of O and ethanol disperses the solid to form a suspension. After centrifuging at 4000r / min to remove the supernatant, the solid is dried to obtain an arrayed soluble polystyrene microsphere template.

[0024] 2) Using 0.2 g of arranged soluble polystyrene microspheres as a template, mix and stir with 8 mL of methanol and 1.311 g of 2-methylimidazole to obtain s...

Abstract

A preparation method of a 2-methylimidazole and zinc complex with a hierarchical porous structure comprises the following steps: 1, mixing arranged soluble polystyrene microspheres adopted as a template with methanol and 2-methylimidazole, and stirring to obtain a solution a; and 2, dissolving zinc nitrate hydrate in methanol to obtain a solution b, adding the solution b to the solution a in a dropwise manner 5min later, stirring the solution a and the solution b at room temperature for 24h, centrifuging the obtained solution mixture, washing the obtained material to obtain a white solid, and removing the arranged soluble polystyrene microsphere template at 80DEG C by using N,N-dimethyl formamide or toluene to obtain the 2-methylimidazole and zinc complex with a hierarchical porous structure. The preparation method has the advantages of simplicity, wide sources of raw materials, low cost and easy industrial amplified production; and the above material finally prepared through the method has the advantages of high specific surface area, facilitation of enhancement of the hydrophobicity and diffusion of organic solvents due to macro-pores, meso-pores and micro-pores, large adsorption quantity of the organic solvents, and certain hydrophobicity.

Description

technical field [0001] The invention relates to a hydrophobic organic solvent adsorption material, in particular to a preparation method and application of a 2-methylimidazole zinc complex with a hierarchical pore structure. Background technique [0002] Metal-organic frameworks (MOFs) are widely used in catalysis, fluorescence, gas adsorption and other fields due to their adjustable composition and pores. This limits its related applications. [0003] Synthesizing MOFs with a hierarchical structure at the mesoscopic scale to have macropores, mesopores, and micropores at the same time can improve the connectivity of MOFs, expose more surface active sites, and improve their catalytic and adsorption properties. However, most MOFs with hierarchical structures only have disordered macropores and mesoporous pores, and the application range of such materials is relatively narrow, mostly focusing on catalysis and adsorption of dyes. Contents of the invention [0004] The purpos...
