Continuous polycrystalline ZIF-8 membrane supported on CO2-selective mixed matrix supports for CO2/CH4 separation†
Abstract
Thin and compact ZIF-8 membranes were successfully synthesized on PES-ZIF-8 mixed matrix supports via secondary growth. An enhancement in the overall CO2/CH4 selectivity was demonstrated by incorporating both a selective ZIF-8 layer and a PES-ZIF-8 mixed matrix support in a membrane.
