        Project:

        Knowledge-based development of supported ZIF membranes for liquid mixture separation by pervaporation

        Abstract:

        In part I of this project, the principles of nano- and microcrystal formation and 2D layer growth on ceramic supports, the prediction of membrane selectivity by combining mixed gas adsorption and diffusion data as obtained by IR microscopy and Molecular Dynamics computer simulations including framework flexibility were studied and understood, resulting in the preparation of several new types of ZIF (Zeolitic Imidazolate Framework) membranes with molecular sieving separation patterns which have been successfully tested in gas phase separations. In this application we will go the step from gas phase separation to the liquid feed separation by MOF membranes. This has so far not been reported in the literature. By combining the determination of mixed equilibria and mixed component diffusion at high pore filling and under consideration of framework flexibility, the MOF membrane development for liquid mixture separation by pervaporation will go in part II from trial and error to knowledge-based. This new aim requires theoretical and experimental development.

        Results:

         

        From the fundamental understanding of mass transport in MOFs we could go in MOF membrane development the way from trial and error to knowledge-based. The principles of nano- and microcrystal formation and 2D layer growth on ceramic supports, the prediction of membrane selectivity by combining mixed gas adsorption and diffusion data as obtained by IR microscopy and Molecular Dynamics computer simulations including framework flexibility were studied and understood resulting in the preparation of several new types of ZIF membranes with molecular sieving separation patterns which have been successfully developed and tested in gas phase separations.
