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.

通过同步加速器红外光谱法在高选择性混合基质膜中定位结合域

已经通过原位同步加速器红外显微技术在混合基质膜(MMM)内建立了对包含MFM-300(Al)和聚合物6FDA-Durene-DABA的CO 2选择性的结合域。的MOF晶体是完全可访问并播放在CO的结合中起关键作用2,从而形成选择性途径以促进CO的渗透2内,并通过MMM。这项研究直接揭示了该MMM总体性能提高的分子机理,包括渗透性,溶解性和对CO 2的选择性。
