Abstract

Mixed matrix membranes (MMMs) are expected to be strong competitors in gas separation membranes. Nevertheless, the poor interaction between fillers and matrix is a major restriction to prepare MMMs with a higher separation performance. In this work, MIL-101(Cr) was functionalized with −NH2, −COOH, and benzenesulfonic acid (−PhSO3H) group and these functionalized MIL-101 particles were embedded in cellulose nanofibers (CNFs) to form MMMs. The interaction effect of functionalized MIL-101 with CNFs on the separation performance was discussed. After the adjustment of MIL-101-NH2 loading, the resulting MIL-101-NH2/CNF membrane with 5 wt% loading exhibited enhanced H2 permeance of ~ 2.56 × 10− 7 mol m−2 s− 1 Pa− 1 with H2/CO2 ideal selectivity of ~ 21.9.
