High quality ZIF-8 membranes of about 2.5μm in thickness were prepared on α-Al2O3 support by secondary growth synthesis in water solution. Single He, H2, CO2, N2, CH4, C3H6 and C3H8 permeation data for the ZIF-8 membranes were measured and analyzed by a permeation model to obtain diffusivity values...
