In situ / operando X-ray absorption spectroscopy (XAS) is a powerful technique with the potential of revealing the electronic and geometric structure of nanoparticulate electrocatalyst systems under gas-evolving conditions, thereby providing vital insight into the nature of the catalytic active site in ...
近日,劳伦斯伯克利国家实验室先进光源Jinghua Guo教授课题组(通讯作者)在国际顶级期刊Nano Letters上成功发表“Trackingthe Chemical and Structural Evolution of the TiS2Electrode in theLithium-Ion Cell using Operando X-ray Absorption Spectroscopy”的论文。论文第一作者为张亮。TiS2作为重量最轻、价格最低的过渡金...
X-ray absorption spectroscopy (XAS) can therefore be used to visualize and quantify lithiation kinetics in transition metal oxide cathodes; however, in-situ measurements are often constrained by temporal resolution and X-ray dose, necessitating compromises in the electrochemistry cycling conditions used ...

In this study, we want to highlight the assets and restrictions of X-ray absorption spectroscopy (XAS) and Mössbauer spectroscopy for investigating the mechanism of the electrochemical reaction of antimony electrode materials vs. Na. For this, operando XAS was carried out during the first one ...
Synchrotron-based soft X-ray absorption spectroscopy (XAS) and X-ray emission spectroscopy (XES) have the capability to probe the unoccupied and occupied electronic structure of materials with elemental selectivity [12], for example, Kim et al. [13] investigated the highest occupied molecular ...
