Embodiment 1

[0045] The preparation method of the zirconium-based metal organic framework material of the present example comprises the following steps:

[0046] 1) Add 10.0 mg (0.024 mmol) of 4,4'-(5,10-phenazinyl)dibenzoic acid (PAZ) to a 5 mL sample bottle, and then add 2.0 mL of N,N-dimethylmethane amide (DMF), put the cap on the sample bottle and put it in an oven, heat it at 100°C for 0.5h to 1h to completely dissolve 4,4'-(5,10-phenazinyl)dibenzoic acid, and then take out the sample bottle and cool it naturally to At room temperature, 20.0 mg (0.086 mmol) of zirconium tetrachloride (ZrCl 4 ), then 50 μL of trifluoroacetic acid (TFA) was added, the sample vial was capped and sealed and placed in an oven for solvothermal reaction, reacted at 120 °C for 48 h, and after the reaction was completed, N,N-dimethylformamide was used for the reaction of the obtained product. The solid product is washed to obtain yellow-brown zirconium-based metal-organic framework crystal materials (Zr-PAZ M...

Description

technical field [0001] The invention belongs to the field of chemistry, and in particular relates to a zirconium-based metal-organic framework material and a preparation method and application thereof. Background technique [0002] Zirconium-based metal-organic framework materials are porous polymer materials formed by linking zirconium salts or zirconium oxides with small organic carboxylic acid molecules through coordination bonds. Compared with classical porous materials (such as molecular sieves, mesoporous silicon, etc.), the biggest advantage of zirconium-based metal-organic frameworks is that the pore size of zirconium-based metal-organic frameworks can be precisely controlled from the atomic level with the help of the rich diversity of organic ligands. size, specific surface area and pore environment, resulting in framework materials with specific crystalline porous structures and pre-designed functions; in addition, with organic porous polymer materials (such as cov...
