学生在高级顶点课程中发展了两部分的本科实验室经验。第一个组成部分是一个3小时的实验室经验,致力于在水溶液中使用现成的试剂和设备快速合成金属有机框架(MOF-808)。在第二组分中,通过粉末x射线衍射(PXRD)、热重分析(TGA)和漫反射红外傅立叶变换光谱(DRIFTS)等一系列仪器对MOF-808进行了表征。此外,利用定量核磁共振波谱法定量测定了从溶液中吸附的全氟丁烷磺酸盐(PFBS)的数量,PFBS是多氟烷基或全氟烷基物质(又名PFAS)的一个例子。这两个3小时的实验经历随后被运用到基础无机化学课程中。这个双组分、多仪器的实验体验为学生提供了一个合成现代多孔固体的机会,并将其用于MOF科学的新兴应用。
A two-component undergraduate laboratory experience has been developed by students in a senior level capstone course. The first component is a 3 h laboratory experience dedicated to the rapid synthesis of a metal–organic framework (MOF-808) in aqueous solution using readily available reagents and equipment. During the second component, MOF-808 was characterized via a suite of instruments: powder X-ray diffraction (PXRD), thermal gravimetric analysis (TGA), and diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS). In addition, quantitative19F{1H} NMR spectroscopy was utilized to quantify the amount of perfluorobutanesulfonate (PFBS), one example of a poly- or perfluoroalkyl substance (aka PFAS), adsorbed from solution. The two 3 h laboratory experiences were subsequently deployed in a foundation level inorganic chemistry course. This two-component, multi-instrument lab experience provides students an opportunity to synthesize a modern porous solid and utilize it in an emerging application of MOF science.
