Gas permeation study of H2 and N2 through zeolitic imidazolate frameworks-8 membrane synthesized viamicrowave-assisted secondary solvothermal growth

In the present work, a continuous and well-intergrown zeolitic imidazole framework (ZIF)-8 membrane was synthesized using microwave-assisted secondary solvothermal growth method. The resultant membrane was characterized through scanning electron microscopy and EDX mapping. The performance of ZIF-8 membrane in the permeation of H2 and N2 were performed at different pressure differences ranging from 100 kPa to 700 kPa. Results showed that, the membrane was highly robust with sustainable permeation performance up to 700 kPa. Furthermore, the resultant membrane exhibited high ideal H2/N2 selectivity of 10.25. © 2006-2016 Asian Research Publishing Network (ARPN). All rights reserved.
