High selectivity ZIF-93 hollow fiber membranes for gas separation†
Abstract
Zeolitic imidazolate framework-93 (ZIF-93) continuous membranes were synthesized on the inner side of P84 co-polyimide hollow fiber supports by microfluidics. MOFs and polymers showed high compatibility and the membrane exhibited H2–CH4 and CO2–CH4 separation selectivities of 97 (100 °C) and 17 (35 °C), respectively.
