What are the Key Applications of TEM in Catalysis?
TEM has several critical applications in the field of catalysis:
- Characterizing Catalyst Nanoparticles: TEM allows for precise determination of particle size, shape, and distribution, which are essential parameters for catalytic activity. - Studying Support Materials: Catalysts are often dispersed on support materials. TEM can be used to analyze the structure and interaction between the catalyst and its support. - Observing Active Sites: The active sites on catalysts where reactions occur can be directly observed using TEM, providing insights into the mechanisms of catalysis. - Analyzing Deactivation Mechanisms: Over time, catalysts may deactivate due to sintering, poisoning, or fouling. TEM can help identify these deactivation mechanisms, aiding in the development of more robust catalysts.
