What Information Can Auger Electron Spectroscopy Provide?
AES can reveal several critical aspects of catalysts:
Elemental Composition: AES can identify the elements present on the surface of the catalyst, which is essential for understanding the active sites. Chemical States: The technique can provide information about the oxidation states and chemical bonding of the surface atoms. Surface Contaminants: AES can detect contaminants that might affect the performance of the catalyst. Depth Profiling: By sputtering the surface layer by layer, AES can provide a depth profile of the elemental composition, which is valuable for studying supported catalysts.
