To understand critical problems associated with solid waste and its consequences for the environment, a laboratory experiment is presented on the synthesis of aluminum-based metal–organic framework (MOF) MIL-53(Al) from household waste (PET bottles and aluminum foil/can), for undergraduate students of chemistry. This work is designed to teach students the research methodology and basic understanding of MOFs and their application in carbon capture and storage (CCS). Students also learnt several instrumentation techniques such as UV–vis spectroscopy, powder X-ray diffraction (P-XRD), Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), and gas sorption to characterize the physicochemical properties of MIL-53(Al). The facile production of MIL-53(Al) enabled the students to investigate its applicability in CO2 sorption. The calculations of essential parameters such as CO2 over N2 selectivity and the use of statistical tools in data processing are also explained to the students. In the end, the instructor presented his/her feedback by evaluating the answer sheets (pre- and postlab work) and by demonstrating the overall lab work through a model presentation.

实验室烹制的MOF,用于CO 2捕集:废物管理的可持续解决方案

为了了解与固体废物相关的关键问题及其对环境的影响,我们进行了一项实验室实验,内容涉及从生活垃圾(PET瓶和铝箔/铝)合成铝基金属有机框架(MOF)MIL-53(Al)可以),供化学专业的本科生使用。这项工作旨在教给学生有关MOF及其在碳捕集与封存(CCS)中的应用的研究方法和基本知识。学生们还学习了多种仪器技术,例如紫外可见光谱,粉末X射线衍射(P-XRD),傅立叶变换红外光谱(FTIR),热重分析(TGA)和气体吸附,以表征MIL-53的理化特性。 (Al)。MIL-53(Al)的简便生产使学生能够研究其在CO中的适用性2.吸附。还向学生讲解了基本参数的计算,例如CO 2超过N 2的选择性以及统计工具在数据处理中的使用。最后,讲师通过评估答卷(实验前和实验后的工作)并通过模型演示来演示整个实验室的工作,从而提出了自己的反馈意见。
