Abstract：

[Co(Im)2]∞ seeds with size of 500nm were obtained in aqueous solution at near room temperature. The characterization of SEM, XRD showed that the [Co(Im)2]∞ crystals with uniform particle size distribution is suitable as seeds for the selected macroporous support. Through secondary growth method in aqueous solutions, continuous and crack-free [Co(Im)2]∞ membrane was successfully obtained on the low-cost macroporous α-Al2O3 support, exhibiting H2 permeance of 1.1×10-8mol m-2s-1Pa-1, with ideal selectivities for H2/CO2, H2/N2 and H2/CH4 ystem of 7.8, 9.1 and 7.9. Moreover, The effects of some parameters including the concentration of solution and synthesis times on the formation of [Co(Im)2]∞ membranes were investigated
