                 Abstract: Continuous UiO-66 membrane was fabricated on α-Al 2O 3 support by pre-coating ZrO 2 layer and
                 seeding-secondary-growth method. The structure and morphology of UiO-66 seed crystal and membrane
                 were characterized by XRD and SEM. The effects of acetic acid content and ZrO 2  transition layer on the
                 structure and morphology of UiO-66 membrane were investigated. The membrane integrity was examined
                 by testing the permeance for gas molecules under the conditions of temperature 25 ¥  and pressure 0.08
                 MPa. The effects of trans-membrane differential pressure and operating temperature on the permeance and
                 selectivity of  i-C 4H 10  and  n-C 4H 10 on  UiO-66   membrane were investigated.  As a result, the ZrO 2  layer
                 helped to obtain a continuous uniform UiO-66 membrane with a thickness of 5 μm. The UiO-66 membrane
                 had  reverse permeance for  i-C 4H 10 and  n-C 4H 10.  This membrane  showed high  selectivity (3.6) for
                                                                             7
                                                                 7
                                                                                     2
                 i-C 4H 10/n-C 4H 10 with corresponding permeances of 4.3910  and 1.2210  mol/(m ·s·Pa).
