Learning Synthesis and Property Measurements of Nanoporous Metal–Organic Framework ZIF-8

This laboratory module is designed for upper-division undergraduate students enrolled in an applied physical chemistry course and integrates the synthesis, multitechnique structural characterization, and adsorption-based evaluation of zeolitic imidazolate framework-8 (ZIF-8) within a three-week module. Students prepare ZIF-8 using a water-based synthesis protocol at ambient temperature and pressure, replacing dimethylformamide, and other hazardous organic solvents commonly employed in metal–organic framework (MOF) synthesis. They then characterize the synthesized ZIF-8 using scanning electron microscopy, X-ray diffraction, and Raman spectroscopy and analyze thermogravimetric analysis, N 2 sorption, and CO 2 sorption datasets to evaluate thermal stability, microporosity, and adsorption-based structure–property relationships. Student learning outcomes are assessed through performance-based assignments, supervised laboratory activities, interviews, and a self-diagnostic questionnaire. Through this connected workflow, students gain hands-on experience in MOF synthesis and characterization, develop quantitative data analysis skills, and strengthen their understanding of reticular chemistry, porous materials, and CO 2 adsorption behavior.
