Abstract: Efficiently separating propene and propane is paramount for the chemical industry but notoriously difficult due to their minimal size and volatility differences. Here, an efficient strategy to overcome this separation challenge was demonstrated through the design of bimetallic zeolitic imidazolate framework (ZIF)-based mixed-matrix membranes (MMMs). Thin-film composite (TFC) membranes were fabricated by integrating monometallic ZIF-8, ZIF-67, and a synergistic bimetallic ZIF-8-67 into a uniquely[...]


Our summary: This study presents a novel mixed-matrix membrane (MMM) using bimetallic ZIF-8-67 and ionic liquid-cellulose acetate for efficient propene/propane separation. The membrane demonstrated a threefold increase in propene permeance and selectivity compared to monometallic counterparts. The findings highlight the potential of bimetallic frameworks to enhance membrane performance for industrial applications.
