| dc.description.abstract | This research is divided into two parts which are majorly focusing on the synthesis of annulated mesoporous silica and microporous material of Zr-Fumarate MOF. In the first part, a series of annulated mesoporous silica (SBA-15) with mercapto functional groups are successfully synthesized under room temperature condition. In this study, we adjust the annulated design with several diisocyanate derivatives. The as-synthesized particles were characterized by X-ray diffraction, 13C NMR, FT-IR spectra, thermogravimetric analysis, nitrogen sorption isothermal, electron microscopy. Notably, these synthesis
conditions are also moderate that the modified SBA-15 materials remain merely no change in their chemical and physical property. Moreover, we also utilized these materials as sorbents for the removal of mercury ion under aqueous solutions, and the results also reveal the exceptional consequence.
In the second part, we developed an aqueous system to synthesize Zr-Fumarate MOF and an in-situ procedure to encapsulate biomolecules such as protein. In order to limit the impact of the acidity and harshness of the synthetic environment on carbonic anhydrase, the synthesis duration was reduced from 2 hours to 15 minutes. According to the result from powder X-ray diffraction patterns (XRD) and scanning electron microscope (SEM), enzyme-encapsulated Zr-fum MOF are still with well morphology. Furthermore, the enzyme activity test showed that enzyme-encapsulated Zr-fum MOF still maintained its activity after the synthetic procedure. | en_US |
