WebApr 12, 2024 · The dynamic evolution of active site coordination structure during a high-temperature reaction is critically significant but often difficult for the research of efficient single-atom catalysts (SACs). Herein, we for the first time report the in situ activation behaviors of the local coordination structure of Pt single atoms (Pt1) during the high … WebJul 19, 2024 · Fundamentals of EXAFS. The aim of an EXAFS experiment is to measure the X-ray absorption coefficient of a selected atomic species as a function of energy .After the absorption edge, the absorption coefficient μ(E) exhibits some oscillations.The oscillations extending from ~30-50 eV up to 1000 eV and more above the edge represent the so …
