Amine-functionalized metal-organic frameworks: structure, synthesis and applications

We present a review on some recent studies on the syntheses, structures and properties of amine-functionalized metal-organic frameworks (MOFs), and highlight the benefits of amino functionality towards potential applications. Owing to the strong interaction between CO 2 and basic amino functionalities, amine-functionalized MOFs have attracted much attention mainly for CO 2 capture. Besides the most widely used in situ synthesis method, post-modification and physical impregnation methods are developed to prepare amine-functionalized MOFs with extremely high CO 2 sorption capacity at low pressures. On the basis of the similar mechanism, amine-functionalized MOF-based membranes, including pure amine-functionalized MOF membranes and mixed matrix membranes, exhibit excellent CO 2 /H 2 , CO 2 /CH 4 and CO 2 /N 2 separation performance. Furthermore, amine-functionalized MOFs also demonstrate potential applications in catalysis. We present a review on some recent studies on the syntheses, structures and properties of amine-functionalized MOFs, and highlight the benefits of amino functionality towards potential applications in CO 2 capture, membranes and catalysis.
