The field of metal–organic framework based mixed matrix membranes (M 4 s) is critically reviewed, with special emphasis on their application in CO 2 capture during energy generation.
17 September 2013 in Journal of the American Chemical Society
Mixed matrix membranes (MMMs) composed of a glassy polymer (polysulfone) and the flexible metal organic framework NH2-MIL-53(Al) exhibit excellent separation properties. In contrast to most reported membranes, CO2/CH4 separation selectivity increases with pressure, related to the flexibility of the filler.
