Abstract

A novel concept for the fabrication of dual-layer metal organic framework (MOF) membranes is presented herein that show great promise in improving permeability and selectivity performance for CO2/N2 separation as compared with the individual constituent MOF materials. A highly selective thin MOF layer with narrow pore size was grown on the surface of a highly permeable MOF layer with large pore size. Most importantly, chemical binding at the interface between the two MOF layers made it possible to achieve continuous, defect-free membranes. The two dual-layer MOF@MOF membranes: SIFISIX-3-Ni@SIFISIX-1-Cu and SIFISIX-3-Ni@HKUST-1, represent the first examples of pure inorganic membranes constructed from dual-layer MOF composites. The CO2/N2 selectivities of the HKUST-1 and SIFSIX-1-Cu membranes were improved from 5.2 to 13.0 and 3.4 to 7.8, respectively, after the growth of a selective layer of SIFSIX-3-Ni onto the surface of those materials.
