Industrial applications of membranes based on metal–organic frameworks (MOFs) are challenged by their complex fabrication procedures and poor processability, despite their huge potential for efficient gas separation. Especially, the consumption of a large amount of toxic, expensive solvent, and harsh operation by conventional solvothermal growth also make it less attractive for industrial production. Herein, a solvent‐free method is proposed to fabricate continuous defect‐free MOF membranes on commercial porous stainless steel substrates, where the metal precursors are electrodeposited on the support followed by a heat treatment with the ligand powder via solid‐state reaction without using any solvent. This strategy is proven to be applicable for various MOF membranes and it is expected to be a facile, cheap, and environmental friendly way for future large‐scale production. © 2018 American Institute of Chemical Engineers AIChE J, 65: 712–722, 2019

旨在有效分离气体的金属-有机骨架膜生长的无溶剂途径

尽管金属-有机骨架（MOF）具有高效气体分离的巨大潜力，但它们的制造过程复杂且可加工性差，这对膜在工业上的应用提出了挑战。尤其是，常规溶剂热生长消耗了大量有毒，昂贵的溶剂以及苛刻的操作，也使其对工业生产的吸引力降低。本文提出了一种无溶剂方法，可在商用多孔不锈钢基材上制备连续无缺陷的MOF膜，其中将金属前体电沉积在载体上，然后通过固相反应用配体粉末进行热处理，而无需使用任何方法溶剂。事实证明，这种策略适用于各种MOF膜，并且有望成为一种简便，便宜，环保的方式进行未来的大规模生产。©2018美国化学工程师学会AIChE J，65：712–722，2019
