APTES-assisted synthesis of ZIF-8 films on the inner surface of capillary quartz tubes via flow system

摘要

A compact ZIF-8 film was successfully prepared in a flow system on the inner surface of a capillary quartz tube using 3-aminopropyltriethoxysilane (APTES) as covalent linker. XRD, SEM and TG techniques were used to characterize the as-prepared film. Present work provides a simple and highly reproducible method to prepare Metal-Organic Frameworks (MOFs) films on such small-scale tubular supports with controllable thickness via simply adjusting synthesis time.
