TEM can deliver a wealth of information pertinent to catalysis, including:
1. Morphology: By observing the shape and size of catalytic particles, TEM helps in understanding how these factors influence catalytic performance. 2. Crystallography: TEM can determine the crystal structure and orientation of catalyst particles, which are vital for catalytic activity. 3. Elemental Composition: Techniques like Energy-Dispersive X-ray Spectroscopy (EDX) integrated with TEM can provide elemental analysis and mapping. 4. Chemical State: Electron Energy Loss Spectroscopy (EELS) coupled with TEM can give insights into the chemical state of the elements. 5. Defects and Interfaces: TEM can reveal the presence of defects, dislocations, and interfaces within the catalyst, which can significantly impact its performance.
