Synchrotron radiation-based X-ray absorption spectroscopy (XAS) is considered as a powerful and effective tool in probing the electronic structure and local environment of materials because the high spatial and temporal resolutions of X-ray flux provided by synchrotron light sources. Owing to these unique characteristics, until now, XAS has been widely used in the fields of photocatalytic, electrocatalytic, lithium ion battery and so on. In this talk, Professor Zhong presented the recent progresses and future application of synchrotron XAS technique in fields of energy conversion and storage.
