ZIF@MOF core-shell functional structure synthesized via controlled ligand-exchange for enhanced CO2 separation in mixed matrix-membranes

Key Points

• To investigate the effects of a core-shell ZIF@MOF structure on the performance of mixed matrix membranes for CO2 separation.
• Synthesis of core-shell ZIF@MOF structures via controlled ligand-exchange.
• Integration of synthesized structures into mixed matrix membranes.
• Assessment of gas separation performance including permeability and selectivity analyses.
• Improved polymer-filler compatibility in mixed matrix membranes.
• Enhanced CO2 permeability compared to traditional membranes.
• Improved selectivity for CO2 over other gases.
