Small-pore CAU-21 and porous PIM-1 in mixed-matrix membranes for improving selectivity and permeability in hydrogen separation

Author affiliations

Abstract

Here, we report the fabrication of mixed-matrix membranes based on CAU-21 as the filler and PIM-1 as the matrix. The filler of the CAU-21 MOF with a crystallite size in the nanoscale and high uniformity was synthesized by a microwave-assisted approach. This small-pore CAU-21 was blended with a highly porous PIM-1 matrix to yield mixed-matrix membranes. The prepared membranes were applied for separating hydrogen from nitrogen and the results revealed very high selectivity of 127 for H2 over N2 and memorable H2 permeability of 7199 Barrer.
