Confined growth of UiO-66 into ultrahigh-loading membranes for efficient hexane isomer separation.

ABSTRACT: The efficient separation of hexane isomers is a crucial process in the petrochemical industry. Mixed-matrix membranes (MMMs) hold tremendous potential for hexane isomer separation. However, maintaining their continuity at high filler loading remains a substantial challenge. Here, UiO-66/PP mixed-matrix membranes are fabricated via an in situ confined growth synthesis strategy that achieves an exceptional filler loading of 72.9 wt%. The resulting UiO-66/PP-(96) membrane maintains structural continuity while effectively discriminating linear and mono-branched hexane isomers from their di-branched counterparts, exhibiting a flux of 473.5 g m^-2 h^-1 and a separation factor of 4.53 for n-hexane/2,2-dimethylbutane mixtures. Remarkably, this membrane enri
