Both Transmission Electron Microscopy (TEM) and Scanning Electron Microscopy (SEM) provide complementary information about the catalyst: - TEM: Offers atomic-level resolution images, revealing the internal structure, defects, and the arrangement of atoms. - SEM: Provides detailed images of the catalyst's surface, revealing its morphology, particle size, and distribution.
These techniques help in visualizing the physical structure and understanding the relationship between structure and catalytic performance.
