[P2.34] Synthesis and characterization of ZIF-7 membranes on porous α-Al2O3 tubes by a novel method

In recent years, metal-organic frameworks (MOFs) membranes have attactted great interest due to their particular properties in separation and catalysis fields . Although there are some reports on MOFs membranes by different fabrication techniques such as in-situ synthesis, secondary growth, microwave-assisted method, etc , searching for good synthesis methods for MOFs membranes are still hot research topics. Here, a novel additive-assisted synthesis method was developed to synthesize ZIF-7membrane on hollow fiber tubes with high reproducibility. XRD, SEM and single gas permeation tests were used to characterize the membranes.
