Embodiment 1
[0029] Example 1 Preparation of ZIF-8 film by wiping ZnO powder on macroporous alumina ceramic carrier
[0030] The macroporous alumina ceramic tube was sequentially treated with 1mol / L NaOH, 1mol / L HNO 3 And deionized water treatment, calcination at 500 ℃ for later use;
[0031] Load the commercially available 50nm ZnO powder on the surface of the ceramic carrier by wiping with bare hands;
[0032] Place the ceramic tube coated with ZnO layer in 0.5mol / L methanol solution of 2-methylimidazole, and keep at 50°C for 2h to pretreat the ZnO layer;
[0033] Dissolve 0.47g of zinc chloride, 0.41g of 2-methylimidazole, and 0.25g of sodium formate into 70mL of anhydrous methanol, place the pretreated ceramic tube coated with ZnO powder vertically in a 100mL polytetrafluoroethylene kettle, and slowly Pour the film-forming liquid into the kettle. The polytetrafluoroethylene kettle was placed in an oven at 100°C for 5 hours. After natural cooling, the ceramic tube after the long fil...

[0035] Example 2 Preparation of ZIF-7 film by wiping ZnO powder on macroporous alumina ceramic carrier
[0036] The macroporous alumina ceramic tube was sequentially treated with 1mol / L NaOH, 1mol / L HNO 3 And deionized water treatment, calcination at 500 ℃ for later use;
[0037] Load the commercially available 50nm ZnO powder on the surface of the ceramic carrier by wiping with bare hands;
[0038] Place the ceramic tube coated with ZnO layer in 0.5mol / L benzimidazole N,N-dimethylformamide solution, and keep at 50°C for 20min to pretreat the ZnO layer;
[0039] Dissolve 1.34g of zinc nitrate and 0.68g of benzimidazole in 70mL of N,N-dimethylformamide, place the pretreated ceramic tube coated with ZnO powder vertically in a 100mL polytetrafluoroethylene kettle, and pour it slowly The film-forming liquid is in the kettle. The polytetrafluoroethylene kettle was placed in an oven at 100°C for 12 hours. After natural cooling, the ceramic tube after the long film was rinsed wit...
