In Situ X-Ray Absorption Spectroscopy Studies of Functional Nanomaterials


X-ray absorption spectroscopy (XAS) is a powerful technique to study the unoccupied states and the local structure around an excited species of atoms from an element present in a material. Recently, in situ XAS is being used to study catalytic transformations, synthesis of nanoparticles and thin films, kinetics of potential battery materials, etc. Such studies can explain the mechanisms associated with the formation of chemical species during various types of reactions. In this chapter, we shall describe how XAS has proved to be a powerful characterization tool for nanomaterials with potential applications by determining the variation in interatomic distances, coordination numbers, and the type of neighboring atoms within the first few coordination shells of the atom of interest in nanoparticles.
