Polycrystalline Metal–Organic Framework Membranes for Pervaporation

Pervaporation (PV) is an emerging membrane technology for liquid separations due to its small carbon footprint. Recently, a large number of metal–organic frameworks (MOFs) have been employed as membrane materials for PV. Herein, advances in polycrystalline MOF membranes for PV are reviewed. The structural characteristics (10 MOFs), fabrication methods (five types), and PV applications (four kinds) of polycrystalline MOF membranes are intensively studied, and their relationships are established. Finally, a perspective on membrane structure, performance, large-scale production, and operation stability under industrial conditions is proposed.
