SIMS has a wide range of applications in catalysis, including:
1. Characterization of Catalytic Materials: SIMS is used to analyze the elemental composition and distribution on the surface of catalysts, such as zeolites, metal oxides, and supported metal catalysts. 2. Identification of Active Sites: By mapping the distribution of elements and isotopes, SIMS helps identify the active sites responsible for catalytic activity. 3. Monitoring Catalyst Deactivation: SIMS can detect surface contaminants and changes in composition that lead to catalyst deactivation, aiding in the development of more robust catalysts. 4. Studies of Reaction Mechanisms: Isotopic labeling combined with SIMS can provide valuable information on reaction mechanisms and pathways in catalytic processes.
