报告大纲

报告题目：Analytical Application of   Terahertz Spectroscopy for Gas Adsorption onto ZIF‑8

摘要：Zeolitic imidazole framework-8   (ZIF‑8) is a promising metal-organic framework (MOF) for the storage, separation,   and detection of gases at room temperature and atmospheric pressure. Intermolecular   interactions between ZIF-8 and adsorbed gas molecules which perform an   important role in the adsorption process, can be attributed to non-covalent   bonds such as van der Waals forces. The resonance frequency of these bonds   falls in the terahertz (THz) frequency band. Skeletal vibration of organic   linkers also occurs in this band and seems to be affected by adsorption.   Previous studies using DFT calculations suggest that the frequency of   open-gate motion exists at the range of 1 to 2 THz. Thus, gas adsorption   onto ZIF-8 can be observed by monitoring changes in its terahertz transmission   spectrum as a function of gas exposure.
