摘要：A "two-in-one" approach, namely, through deposition of APTES-ffinctionalized Al2O3 particles onto a coarse macroporous support, was applied to synthesize zeolitic imidazolate tramework-7 (ZIF-7) membranes. The effect of molar ratio of APTES and Al2O3 particles on the formation of ZIF-7 membranes were investigated in detail. When n(APTES:)n(Al2O3) =1:3, the obtained continuous and thin ZIF-7 membrane with thickness ranging from 2 to 3 mu m exhibited H-2 permeance at 4.70x10(-7) mol/(m(2).s.Pa). Its ideal molecular sieving selectivity of H-2/CO2 and H-2/N-2 was at 5.87 and 4.59, respectively.
