Abstract

A seeded growth method is used to prepare preferentially oriented, and well-intergrown films of microporous metal organic framework (MMOF) on porous α-alumina discs. A randomly oriented seed layer is deposited which leads to an oriented membrane as a result of competitive grain growth during the secondary growth process. The orientation is such that the pores are preferentially aligned along the membrane thickness and the membrane exhibits ideal selectivity for H2/N2 as high as 23.
