碩士 === 國立勤益科技大學 === 化工與材料工程系 === 106 === In this thesis, many copper-containing or nickel-containing porous metal-organic framworks (MOFs) were prepared by microwave method. The thermal stability, crystal structures and crystallinity, morphology, and nitrogen adsorption properties of these synthesized MOFs were characterized with thermal field emission scanning electron microscope (TFE-SEM), X-ray diffractometer (XRD), and surface area analyzer (BET), thermogravimetric analyzer (TGA), respectively. From the result of SEM observation and BET analysis, MOFs constructed by Cu-BTC and Cu-BDC exhibit block or laminate-like structures, and MOFs constructed by Ni-BTC and Ni-BDC exhibit block, granular, or narrow strip-like structures, respectively. Specific surface areas of Cu-BDC, Cu-BTC, Ni-BDC, and Ni-BTC were 51.43, 285.29, 18.07, and 8.32 m2/g, respectively. With DABCO introduced into MOFs, specific surface area of Cu-BDC-DABCO and Ni-BDC-DABCO were increased to 232.67 and 524.18 m2/g, respectively, due to their porous containing morphology. For the specific surface area of Cu-BDC-Bipy and Ni-BTC-Bipy were increased to 509.43 and 215.21 m2/g, respectively.
