Embodiment 1
[0028] Take 20g of copper nitrate trihydrate, 10g of trimesic acid, 800g of deionized water and 1g of polyetheramine D-230, mix them, and stir at 200rpm for 1h at 20°C to obtain a copper-based metal-organic framework material prepolymer. Take 50g of silica sol, 105g of pseudo-boehmite, 115g of phosphoric acid solution with a mass concentration of 85% and 900g of deionized water, mix them, stir and react at 550rpm at 150°C for 3.5h, and obtain a mesoporous molecular sieve precursor. The mesoporous molecular sieve precursor and the copper-based metal-organic framework material prepolymer were placed in a closed reaction kettle at a mass ratio of 1:7, and stirred and reacted at 450 rpm at 225°C for 24 hours. The resulting mixture was centrifuged, washed repeatedly with deionized water, and dried at 180° C. for 12 hours to obtain a composite material.
Embodiment 2
[0030]20g of copper nitrate trihydrate, 8g of trimesic acid, 600g of deionized water and 0.6g of polyetheramine D-230 were mixed, and stirred at 260rpm at 25°C for 3h to obtain a copper-based metal-organic framework material prepolymer. Take 50g of silica sol, 80g of pseudo-boehmite, 95g of phosphoric acid solution with a mass concentration of 85% and 750g of deionized water, mix them, stir and react at 400rpm at 140°C for 1h, and obtain a precursor of mesoporous molecular sieve. The mesoporous molecular sieve precursor and the copper-based metal-organic framework material prepolymer were placed in a closed reaction kettle at a mass ratio of 1:6, and stirred and reacted at 300 rpm at 210 ° C for 20 h. The resulting mixture was centrifuged, washed repeatedly with deionized water, and dried at 170° C. for 10 h to obtain a composite material.
Embodiment 3
[0032] 20g of copper nitrate trihydrate, 12g of trimesic acid, 1000g of deionized water and 1.2g of polyetheramine D-230 were mixed, and stirred at 350rpm at 30°C for 5h to obtain a copper-based metal-organic framework material prepolymer. Take 50g of silica sol, 125g of pseudo-boehmite, 165g of phosphoric acid solution with a mass concentration of 85% and 1000g of deionized water, mix them, stir and react at 600rpm at 160°C for 4h, and obtain a precursor of mesoporous molecular sieve. The mesoporous molecular sieve precursor and the copper-based metal-organic framework material prepolymer were placed in a closed reaction kettle at a mass ratio of 1:8, and stirred and reacted at 500 rpm at 240 ° C for 30 h. The resulting mixture was centrifuged, washed repeatedly with deionized water, and dried at 200° C. for 15 h to obtain a composite material.
