Embodiment 1
[0021] 1) Synthesis of metal organic framework ZIF-67:
[0022] Cobalt nitrate hexahydrate (1.4552g) and dimethylimidazole (3.284g) were added to 100 milliliters of anhydrous methanol respectively. After cobalt nitrate hexahydrate was stirred and dissolved, they were added to the methanol solution of dimethylimidazole and continued to stir for about 10 minutes, then reacted at room temperature for 12 hours, centrifuged the obtained purple product, washed three times with methanol, and dispersed in 20 ml of methanol;
[0023] 2) Preparation of metal-organic framework ZIF-67@ZIF-8 by epitaxial growth method
[0024] Zinc nitrate hexahydrate (0.3719g) and dimethylimidazole (0.8210g) were added to 100 ml of anhydrous methanol respectively, and the metal organic framework ZIF-67 was added to the methanol solution of dimethylimidazole, and stirred for about 30 Minutes, then add the methanol solution of zinc nitrate hexahydrate to the above solution, continue stirring for about 10 m...
