摘要

ZIF-8 membranes were synthesized by in-situ crystallization on tubular porous α-alumina supports.First, ZIF-8 seeds were prepared solvothermally from a solution containing zinc nitrate hexahydrate, methanol, and 2-methylimidazole. This solution was transferred to a teflon lined stainless steel autoclave and heated in a conventional oven at 150℃ for 5 hrs. After cooling, the solids were separated by centrifugation and washed with methanol.
