What are the Common Techniques in Surface Spectroscopy?
Several surface spectroscopy techniques are commonly used in the study of catalysis:
1. X-ray Photoelectron Spectroscopy (XPS): Provides information about the elemental composition and chemical state of the surface. 2. Auger Electron Spectroscopy (AES): Used for surface compositional analysis with high spatial resolution. 3. Infrared Reflection Absorption Spectroscopy (IRRAS): Probes the vibrational modes of molecules adsorbed on surfaces. 4. Raman Spectroscopy: Offers insights into the molecular structure and interactions on the catalyst surface. 5. Ultraviolet Photoelectron Spectroscopy (UPS): Helps in understanding the electronic structure and work function of the surface.
