Metal-organic frameworks (MOFs) are porous materials composed of metal ions and organic ligands. These materials have garnered significant attention due to their wide-ranging applications, such as the capture of hazardous molecules, catalysis, production of value-added compounds, and detection of ions or molecules in water. Despite their immense potential in various research fields, MOFs are rarely introduced in lower-division undergraduate chemistry courses. In this study, we aim to kindle student enthusiasm in research through the development of a new laboratory experience involving MOFs. Using an inquiry-based learning approach, students were tasked with synthesizing, characterizing, and utilizing MOFs to capture a hazardous molecule. Over three laboratory periods, undergraduate students received instructions for synthesizing four MOFs. They were given the freedom to select which MOF to synthesize and use to capture either methylene blue or iodine. This hands-on experience exposed students to techniques not typically explored in general chemistry, including the use of crystallographic information files to study MOF structures, powder X-ray diffraction, Fourier transform infrared spectrometry, and nitrogen sorption isotherms. At the end of the term, students presented their work during a formal poster session, where they received feedback from faculty and graduate students at Oregon State University. Additionally, students participated in a survey to share their thoughts on the educational outcomes of this new experiment, in which they expressed their interest in further exploring MOFs and chemistry in general in the future.
