Synthesis of continuous MOF-5 membranes on porous α-alumina substrates

Can Metal–Organic Framework Materials Play a Useful Role in Large‐Scale Carbon Dioxide Separations?

“…[141] The scale-up of thin-film membranes of this type to the very large surface areas that will be required for large-scale applica- [142,143] The fabrication of thin-film MOF membranes has only been explored very recently. The first continuous and well-intergrown IRMOF-1 membrane was prepared on a porous alumina support by in situ solvothermal synthesis by Liu et al [144] Gas permeation results showed that diffusion of CO 2 , CH 4 , H 2 , N 2 , and SF 6 through an IRMOF-1 membrane mainly follows a Knudsen diffusion scaling. Bux et al [145] prepared a continuous intergrown layer of ZIF-8 on a porous titania support and measured the volumetric flow rates of single gases: CO 2 , H 2 , O 2 , N 2 , and CH 4 .…”

Controlling the size and shape of Mg-MOF-74 crystals to optimise film synthesis on alumina substrates

“…ZIF-8 [10][11][12] , MOF-5 13 , HKUST-1 14,15 etc [16][17][18][19] ) on porous substrates with a clear, definitive MOF layer have been applied to gas separations, overcoming some of the issues associate with MMMs 3 . Typically, these membranes require long syntheses times and multiple steps to produce defect free barriers.…”

Co3(HCOO)6 Microporous Metal–Organic Framework Membrane for Separation of CO2/CH4 Mixtures

“…[26][27][28][29][30][31][32][33][34][35][36][37] These properties make them attractive for the preparation of defect-free and continuous membranes. [38][39][40][41][42][43][44] For instance, a copper-net-supported HKUST-1 membrane with selectivity towards H 2 /N 2 in gas separation has been reported. [45] This material is anticipated to show selectivity for hydrogen over other permanent gases.…”
