Different from conventional method which places α-Al2O3 in the liquid precursor solution for preparing inorganic gas separation membrane, these methods are inexpensive for membrane fabrication in the vapor phase condition. In this research, we developed four methods for membrane synthesis in the vapor phase. The membrane coverage and uniformity were improved by adjusting the experimental process and parameters. In addition, membrane synthesis with different conditions resulted in different crystal morphologies, such as bulk-like and rod-like crystals. Namely, we could control the membrane morphology by synthetic methods and phases. Material growing on α-Al2O3 was identified by X-ray diffraction (XRD). Scanning electron microscopy (SEM) was used for morphology analysis. Different surface area of MIL-53 (Al) synthesized by conventional electric and microwave-assisted heating was confirmed by BET surface area measurement.
