Xas

This article primarily interprets the perspective of S. N. Ehrlich from the University of Delaware on the in-situ characterization of catalyst phase morphology using XAS, XRD, and Raman spectroscopy.

X-ray Absorption Spectroscopy (XAS) and Synchrotron Absorption Spectroscopy (XAFS) are two analytical techniques based on the principles of X-ray spectroscopy. The purpose of this article is to describe the differences and connections between them.
