Embodiment 1
[0064] Example 1 Preparation of a multi-defective amine functionalized metal-organic framework material
[0065] Amine-functionalized metal-organic frameworks were prepared according to the following method:
[0066] S1. At room temperature, 233mg (1mmol) zirconium tetrachloride (ZrCl 4 ) was stirred and dissolved in 50mL of N,N-dimethylformamide (DMF) solvent;
[0067] S2. Add 181 mg (1 mmol) of 2-aminoterephthalic acid (ATA) into the S1 mixture, and stir at a constant speed until the solute is completely dissolved, and the solution is clear and transparent;
[0068] S3. After step S2, the mixed solution was transferred to a stainless steel reaction kettle lined with polytetrafluoroethylene with a volume of 100ml, reacted at 120°C for 48h, and then naturally cooled to room temperature;
[0069] S4. After step S3, filter to obtain a solid product, wash with DMF and anhydrous methanol three times respectively, and freeze-dry, that is, the freeze-drying parameters are: freezin...
