Application of XAFS to Catalytic Materials

Abstract

EXAFS spectroscopy is a powerful technique to determine local structure of a selected atomic species in a sample in any aggregation state and under any kind of atmosphere; for these reasons it is widely used in catalysis. A brief phenomenological explanation of the EXAFS signal and a short description of data collection and data analysis methods are presented. A recent example of its application to a heterogeneous catalytic system is illustrated.
