由太平洋西北国家实验室、SLAC国家加速器实验室、日内瓦大学和奥克兰大学等机构组成的研究团队，利用超快X射线技术首次在单一研究中同时具有局部和结构灵敏度地捕捉到质子耦合电子转移反应过程1。该研究成果已于2026年10月6日发表在《自然通讯》杂志第17卷第1期上1。研究团队通过结合超快X射线吸收光谱、X射线散射和时间分辨表征等技术手段，揭示了电子和质子的协调运动如何与周围水分子的重新组织相耦合1。
研究团队首席作者Elisa Biasin表示："我们首次捕捉到与质子转移相关的电子变化如何与周围溶剂的重新组织相耦合"1。这一发现为改进流电池、燃料电池和催化剂的设计提供了新的科学依据1。该项研究得到了美国能源部科学办公室基础能源科学部的支持1。
Researchers from the Pacific Northwest National Laboratory and collaborating institutions have used ultrafast X-ray technology to directly observe the crucial steps of proton-coupled electron transfer reactions for the first time.1 The team combined ultrafast X-ray absorption spectroscopy, X-ray scattering, and time-resolved characterization techniques to simultaneously capture both local and structural details of these reactions in a single study.1 Lead researcher Elisa Biasin noted that the breakthrough reveals how "electron changes related to proton transfer couple with the reorganization of surrounding solvent molecules."1
The findings, published in Nature Communications in October 2026, demonstrate the coordinated movement of electrons and protons in relation to the rearrangement of water molecules surrounding the reaction site.1 This fundamental understanding could accelerate the development of more efficient catalysts, fuel cells, and flow batteries by providing clear design principles for these technologies.1 The research was supported by the U.S. Department of Energy's Office of Science and the Basic Energy Sciences Division.1
