| Summary: | 碩士 === 國立高雄應用科技大學 === 化學工程與材料工程系碩士在職專班 === 105 === In this study, Zinc based metal organic framework material (Zn-MOF-74) was grafted on MgO hollow tube by hydrothermal method (Zn-MOF-74@MgO tube) to enhanced its CO2 adsorption capacity.
The composites were characterized by scanning electron microscopy(SEM), X-ray diffraction(XRD), which confirmed the growth of Zn-MOF-74 nanocrystals on the MgO tube surface and the composite exhibit characteristics of both the components.
Nitrogen adsorption-desorption isotherms measurements indicated the Zn-MOF-74 was a mesoporous sample with a specific surface area of 115.02 m2 / g and a pore size of 2.698 nm. Furthermore, the Zn-MOF-74@MgO tube reveal mesoporous structure.
Zn-MOF-74 showed a good CO2 adsorption capacity at 30 °C. Furthermore, only a small amount of Zn-MOF-74 was grafted on MgO hollow tube efficiency enhanced the adsorption capacity of CO2.
