Abstract

Ultrathin ZIF-8 membranes with a thickness of around 200 nm
were prepared by chemical vapour modification of surface chemistry
and nanopores of an asymmetric bromomethylated poly(2,6-
dimethyl-1,4-phenylene oxide) (BPPO) substrate. The resulting
ZIF-8 membranes exhibited exceptional H2 permeance as high as
2.05 106 mol m2 s1 Pa1 with high H2/N2 and H2/CO2
selectivities (9.7 and 12.8, respectively).
