Embodiment 1
[0015] (1) Solution configuration: Zinc nitrate and 2-methylimidazole were dissolved in methanol to prepare a metal precursor solution A with a concentration of 0.5 mol / L and an organic ligand solution B with a concentration of 0.5 mol / L.
[0016] (2) Mixing: Place A solution and B solution on both sides of a microfiltration membrane with a pore size of 0.01 microns, and control the pressure difference on both sides of the membrane to 0.02MPa, so that A solution can evenly pass through the membrane and enter B solution. The reaction temperature is 30°C, the type of reactor used is a flat membrane, and the membrane material is polyethersulfone (PES).
[0017] (3) Post-treatment: The white colloidal suspension obtained above was centrifuged at 10,000 r / min, washed twice with methanol, and dried at 80° C. for 10 h to obtain a nano-sized zeolite metal-organic framework compound.
[0018] The measured particle size is 32.44nm and the specific surface area is 980.4332m 2 / g.
