Method of synthesizing and preparing zeolitic imidazolate framework material ZIF-8 nanometer six-foot body by using seed growth

[0034] A method for using seed growth synthesis to prepare zeolite imidazolate framework material ZIF-8 nano hexapods, comprising steps as follows:

[0035] (1) 24 μmol of zinc nitrate, 1.32 mmol of 2-methylimidazole, 1.92 μmol of cetyltrimethylammonium bromide, and 3 mL of water were mixed and dissolved at room temperature, and the mixture was incubated at room temperature for 3 hours. The reaction solution was washed to obtain ZIF-8 cube seeds, and dispersed in 3 mL of water to obtain a seed dispersion.

[0036] (2) Mix and dissolve 48 μmol of zinc nitrate, 1.32 mmol of 2-methylimidazole, 1.44 μmol of cetyltrimethylammonium bromide, 200 μL of seed dispersion, and 3 mL of water at room temperature, and keep the mixture in After 3 hours at room temperature, the reaction solution was washed to obtain the ZIF-8 nano-hexapod product.
