Mixed-Matrix Membranes (MMM) could provide a near term solution to the
permeability/selectivity trade-off with polymeric gas separation membranes and bridge the gap with
inorganic membranes. While zeolite and carbon additives have shown promise, the corresponding
mixed-matrix membranes are limited by low loadings and interfacial defects such that the true potential
of MMMs has not been realized. Metal-Organic Frameworks (MOF), on the other hand, provide
exceptionally high surface areas and organic linkers that could enhance selective gas transport and
improve polymer/particle interactions. In this review, recent theoretical and experimental results for
MOF-based mixed-matrix membranes will be described.
