The crystalline porous materials (CPMs) with uniform and regular pore systems show great potential for separation applications using the membrane technology. Along with the research on synthesis of precise-engineered porous structures, a significant attention on the practical application of these materials for preparation of crystalline porous membranes (CPMBs) is paid. In this review, the progress made in the preparation of thin, large area and defect-free CPMBs using classical and novel porous materials and processing is presented. The current state-of-the-art of scalable CPMBs with different nodes (inorganic, organic and hybrid) and various linking bonds (covalent, coordination, and hydrogen bond) is revealed. The advances made in the scalable production of high-performance crystalline porous membranes are categorized according to the strategies adapted from polymer membranes (interfacial polymerization, solution-casting, melt extruding and polymerization of CPMs) and tailored based on CPMs properties (seeding-secondary growth, conversion of precursors, electrodeposition and chemical vapor deposition). Finally, the performance and challenges in the preparation of scalable CPMBs with emphasis on their sustainability are presented.
