Catalyst Characterization I

This lecture covers the identification of compounds through infrared spectroscopy, including inorganic materials like metal oxides, and the detailed characterization of surface sites using molecular probes and in situ experiments. It also discusses vibrational spectroscopy, providing information on molecular bonds and functional groups. The lecture delves into the use of probe molecules to analyze acid sites, emphasizing the importance of criteria like intermolecular interaction and acid strength. Examples with zeolites and molecules like pyridine are presented to illustrate the analysis of different channel sizes and acid sites. The lecture concludes with the indirect characterization of supported metal oxide functionalities using probe molecules like ammonia.
