Abstract

The binding domains within a mixed matrix membrane (MMM) that is selective for CO₂ comprising MFM-300(Al) and the polymer 6FDA-Durene-DABA have been established via in situ synchrotron IR microspectroscopy. The MOF crystals are fully accessible and play a critical role in the binding of CO₂, creating a selective pathway to promote permeation of CO₂ within and through the MMM. This study reveals directly the molecular mechanism for the overall enhanced performance of this MMM in terms of permeability, solubility and selectivity for CO₂.
