Metal–organic frameworks (MOFs) are an emerging class of materials for potential use in separation. ZIF-71 has super-hydrophobic pore channels and a very flexible architecture, which make candidate recovering bio-alcohols from fermentation broths. In the present study, mixed matrix membranes (MMMs) based on PDMS were prepared separation alcohols (methanol, ethanol, isopropanol (IPA) or sec-butanol) aqueous solutions. Experimental results reveal that pervaporation performance membrane was improved both flux factors upon embedment ZIF-71. The filled (PDMS : = 10 2) nearly double compared to those unfilled membranes, suggesting is excellent filler prepare organophilic bio-alcohol recovery.
