Embodiment 1
[0021] Example 1: Weigh 0.135g of ferric chloride hexahydrate, place it in 15mL of ethylene glycol, stir at 40°C for 1 hour to form A solution; weigh 0.206g of terephthalic acid and 0.675g of ferric chloride hexahydrate Dissolve in 20mL N,N-dimethylformamide solvent to form B solution, pour A solution into B solution, stir evenly, put the solution into a 50 mL high-pressure stainless steel reaction kettle with polytetrafluoroethylene lining , reacted at 110 °C for 20 h. The resulting precipitate was centrifuged, washed with DMF and anhydrous methanol, and dried at 80 °C to obtain MIL-101(Fe)-1 with special morphology.
Embodiment 2
[0022] Example 2: Weigh 0.135g of ferric chloride hexahydrate, place in 15mL of ethylene glycol, stir at 40°C for 2h to form A solution; weigh 0.206g of terephthalic acid and 0.675g of ferric chloride hexahydrate Dissolve in 20mL N,N-dimethylformamide solvent to form B solution, pour A solution into B solution, stir evenly, put the solution into a 50 mL high-pressure stainless steel reaction kettle with polytetrafluoroethylene lining , reacted at 110 °C for 20 h. The resulting precipitate was centrifuged, washed with DMF and anhydrous methanol, and dried at 80 °C to obtain MIL-101(Fe)-2 with a special shape.
Embodiment 3
[0023] Example 3: Weigh 0.135g of ferric chloride hexahydrate, place in 15mL of ethylene glycol, stir at 40°C for 3h to form A solution; weigh 0.206g of terephthalic acid and 0.675g of ferric chloride hexahydrate Dissolve in 20mL N,N-dimethylformamide solvent to form B solution, pour A solution into B solution, stir evenly, put the solution into a 50 mL high-pressure stainless steel reaction kettle with polytetrafluoroethylene lining , reacted at 110 °C for 20 h. The resulting precipitate was centrifuged, washed with DMF and anhydrous methanol, and dried at 80 °C to obtain MIL-101(Fe)-3 with a special shape.
