Zeolitic imidazolate frameworks (ZIFs) have been the focus of interest for their physical and chemical properties,especially, for their extraordinary gas separation properties. In this study, a novel and efficient method for the fabricationof continuous ZIF-7 film on α-alumina substrate has been investigated. The electrospray deposition method wastried for the first time to prepare ZIF films directly without the necessity of prior substrate seeding. It has the advantage ofdepositing thin ZIF-7 films directly on the α-alumina substrate by electrospraying the precursor solution. The ZIF-7 filmshave been characterized through XRD, FE-SEM, and single gas permeation tests.
