What Information Can X-ray Absorption Spectroscopy Provide?
X-ray absorption spectroscopy (XAS) is divided into two main techniques: X-ray Absorption Near Edge Structure (XANES) and Extended X-ray Absorption Fine Structure (EXAFS). XANES provides information about the oxidation state and electronic structure of the catalyst, while EXAFS offers details about the local atomic environment, such as the distances and coordination numbers of neighboring atoms. Together, these techniques help in understanding the electronic and structural properties of the catalyst under working conditions.
