<i>In Situ</i>/<i>Operando</i> Electrocatalyst Characterization by X-ray Absorption Spectroscopy
Janis Timoshenko, Beatriz Roldán Cuenya
Abstract
XAS to probe the catalyst's interactions with the environment (support, electrolyte, ligands, adsorbates, reaction products, and intermediates) and its structural, chemical, and electronic transformations as it adapts to the reaction conditions.
