In this study, ZIF-7 membranes were successfully prepared on macroporous alpha-alumina substrate by in situ solvothermal method, without the necessity of seeding or surface modification step. Addition of sodium formate during the reaction facilitates continuous well-intergrown crystalline ZIF-7 layer. As-synthesized ZIF-7 membrane was characterized by XRD, FE-SEM and gas permeation test. The H-2 permeance through 5 mu m ZIF-7 membrane was 1.9x10(-7) mol/m(2).s.Pa with ideal selectivity of H-2/CO2 = 15.2.
