ABSTRACT
Infrared (IR) spectroscopy and catalysis represent two of the most practically relevant topics in chemistry, but they are normally taught in separate contexts at the undergraduate level. Although IR spectroscopy is introduced to students as a tool for organic compound characterization, it also finds wide applicability in the investigation of catalytic reactions. Here we present a laboratory exercise that binds the concepts of IR spectroscopy and catalysis together in the study of nitrogen oxide abatement by selective catalytic reduction-a reaction that is of industrial relevance and environmental importance. We originally designed the practical course for in-person instruction, but we adapted it into a virtual learning experience during the COVID-19 pandemic. Our analysis revealed that there was no significant difference between the performance of the in-person and virtual participants, suggesting that the online offering of the course could be a viable alternative to face-to-face instruction in case of extraordinary circumstances.
