What Are the Advantages of Using AES in Catalysis?
The use of AES in catalysis offers several advantages: 1. Surface Sensitivity: AES is highly sensitive to the top few atomic layers, making it ideal for studying surface phenomena. 2. Elemental Identification: AES provides precise elemental identification, which is crucial for characterizing complex catalytic surfaces. 3. Chemical State Analysis: AES can provide information on the chemical states of the elements, helping to understand the active sites in catalysts. 4. Spatial Resolution: AES can be combined with scanning techniques to obtain spatially resolved information, allowing for the study of heterogeneous catalysts.
