Embodiment 1
[0039] 1. Preparation of organophosphine-grafted hollow zirconium metal-organic framework materials:
[0040] Such as figure 1 As shown, the specific steps of the preparation method of organophosphine grafted hollow metal organic framework materials include:
[0041] (1) Add 0.384g 2-aminoterephthalic acid, 0.54g zirconium tetrachloride, 120mL dimethylformamide (DMF) and 10mL acetic acid to the reaction vessel, stir at room temperature for 20min, pour the reaction solution into four In a vinyl fluoride reactor, react at 120°C for 24h, wash with DMF and methanol for 3 times, and vacuum dry at 60°C to obtain the zirconium metal organic framework (Zr-MOF-NH 2 ).
[0042] (2) Add 8.25g of sodium tungstate and 25mL of water into the reaction vessel, stir at room temperature for 30min, and use 2mol L -1 HCl to adjust the pH of the solution to 2.0, then add water to obtain a 250 mL solution, and add oxalic acid to adjust the pH of the solution to 2.3. Take 70mL solution and add i...
