XAS is a core-level spectroscopy technique, using a photo-excited electron from a core level (e.g. 1s or 2p) to probe unoccupied valence levels as well as the neighboring atomic structure. The ionization of core levels requires photons in the energy in the X-ray range, and spectroscopy requires. X-ray absorption spectroscopy (XAS) is sensitive to the internal structures of metal nanoparticles and to the species adsorbed on them []. Chemical sensitivity of XAS derives from the fact that each element has a characteristic X-ray absorption spectrum. X-ray absorption spectroscopy (XAS) has become an indispensable tool to in situ investigate dynamic natures of electrocatalysts but still suffers from limited energy resolution, leading to significant electronic transitions poorly resolved. Herein, we highlight advanced X-ray spectroscopies.
