Incorporation of MIL-53(Al) MOF in polyethersulfone for preparation of CO2/CH4 separation mixed matrix membrane

Flexible crystalline metal−organic framework (MOF) of nanosize particles (MIL-53(Al)) and polyethersulfone were used to produce mixed matrix membranes (MMM) with different MOF weight percentages (0–10 wt.%). These MMM display excellent CO2/CH4 separation properties even without any compatibilization. The permeability of pure CO2 and CH4 gases for all membranes were measured and the ideal CO2/CH4 selectivity was calculated. The ideal selectivity was found to increase with increasing MOF loading
