1. Identification of Active Sites: It helps in identifying the active sites on a catalyst surface that are responsible for oxidation reactions. 2. Characterization of Catalyst Deactivation: TPO can be used to study the deactivation mechanisms of catalysts by identifying the nature and quantity of coke or other residues accumulated on the catalyst surface. 3. Optimization of Catalyst Performance: By understanding the oxidation behavior, researchers can optimize the performance and longevity of catalysts in industrial processes.
