英文摘要	a highly oriented zeolitic imidazolate framework 8 (zif-8) composite membrane was prepared by seeding and secondary growth. by dip-coating, preformed zif-8 nanocrystals were attached to the surface of a porous a-alumina support using polyethyleneimine is the coupling agent. after solvothermal treatment, a continuous and well-intergrown zif-8 layer was obtained. x-ray diffraction analysis of the membrane showed preferred orientation of the {100} plane parallel to the support. further time-dependent investigations by scanning and transmission electron microscopy as well as x-ray diffraction indicated that the preferred orientation develops during an evolutionary growth process. in gas mixture permeation experiments, the membrane showed good performance in h-2/hydrocarbon separation. a sharp molecular sieve separation is observed for an equimolar h-2/c3h8 mixture with a separation factor above 300.
