Abstract: This review summarizes the recent research progress of metal-organic framework(MOF)membrane for the efficient separation of small molecules and ions. Owing to their high crystallinity,designable struc-tures,tunable pore sizes and easy functionality,MOF membranes have attracted great research attention and being considered as excellent candidates for separation technology. Given the tremendous progresses made in recent years,it is timely and worthy to systematically summarize the recent advances and shed light on the future trend in this multidisciplinary field. In this review,four common fabrication methods of MOF mem-branes are firstly summarized,including layer-by-layer assembly(liquid-phase epitaxy and Langmuir-Blodgett deposition),vacuum-based fabrication(chemical vapor deposition and atomic layer deposition),electrochemi-cal deposition and powder MOF-based deposition. Furthermore,three emerging separation applications of MOF membranes are minutely described,including gas separation,liquid separation,and ion/proton conduc-tivity. Finally,a summary proposed some key scientific challenges and the possible solution,showing future perspectives of the development of this filed.
