| Summary: | 碩士 === 中原大學 === 化學研究所 === 103 === This dissertation consists two parts, the first one deals the synthesis and
characterization of three new metal-organic frameworks (MOFs) which are
formulated as follows,
[Al(OH)(TDC)] ......................... (1)
[Ga(OH)(TDC)] ........................ (2)
[In(OH)(TDC)] .......................... (3)
where H2TDC = 2,5-thiophenedicarboxylic acid. The new MOFs have been
preliminarily characterized using power X-ray diffraction (PXRD)
measurements and elemental analysis. Field emission scanning electron
microscopy has been used to analyze the crystal morphology and particle size of
the new MOFs. The thermal properties of the MOFs were evaluated with aid of
thermogravimetric analysis (TGA). Moreover, the N2, CO2, H2, and CH4 gas
sorption properties of the new MOFs have been investigated.
The final part of the dissertation explains the effect of HCl addition on the
properties of the new aluminium MOF, 1. The Al-MOF has been synthesized as
described in part 1 with extra addition of HCl (0 ~ 14 mmol) in different
proportions. The resulting Al-MOF samples have been analyzed using the
techniques as mentioned above and the role of HCl addition on the properties of
the Al-MOF has been evaluated.
