Synchrotron radiation-based X-ray absorption spectroscopy (XAS) has been demonstrated to be a powerful and effective characterization tool in comprehensively and deeply understanding the photoelectrochemical (PEC) water-splitting process owing to its unique capability in probing the electronic structure changes of photoelectrodes. In this Review, we present the most recent achievements in the past few years of synchrotron XAS techniques for the advanced investigation of hematite and other commonly used photoanodes. By focusing on the unique and powerful roles that XAS played in identifying the chemical compositions and exploring the working mechanism of various photoanodes, we will provide an in-depth understanding on how the XAS technique can guide the design of efficient photoanodes and contribute to the further development of PEC water splitting. The Review is also expected to stimulate more interest from the PEC community in general for taking advantage of XAS to facilitate their research.

用X射线吸收光谱法了解光电化学水氧化

基于同步辐射的X射线吸收光谱（XAS）由于具有探测光电子电子结构变化的独特能力，已被证明是一种强大而有效的表征工具，可以全面而深刻地理解光电化学（PEC）的水分解过程。。在本综述中，我们介绍了同步加速器XAS技术在过去几年中对赤铁矿和其他常用光阳极的高级研究的最新成果。通过专注于XAS在识别化学成分和探索各种光阳极的工作机制方面所发挥的独特而强大的作用，我们将提供有关XAS技术如何指导高效光阳极设计并为PEC水分解的进一步发展做出贡献的深入了解。总体而言，该评论还有望激发PEC界对利用XAS促进研究的兴趣。
