Polycrystalline Metal-Organic Framework Membranes for Pervaporation

Pervaporation (PV) is an emerging membrane technologyfor liquidseparations due to its small carbon footprint. Recently, a large numberof metal-organic frameworks (MOFs) have been employed as membranematerials for PV. Herein, advances in polycrystalline MOF membranesfor PV are reviewed. The structural characteristics (10 MOFs), fabricationmethods (five types), and PV applications (four kinds) of polycrystallineMOF membranes are intensively studied, and their relationships areestablished. Finally, a perspective on membrane structure, performance,large-scale production, and operation stability under industrial conditionsis proposed.
