摘　　要：可再生能源电解水产氢对于实现碳中和目标和未来可持续社会的发展具有重要意义。然而,在电解水服役过程中,催化材料往往会发生复杂的结构演变,这对深入理解电解水催化材料反应机制和精准设计高效催化材料造成了挑战。原位电化学拉曼表征技术对催化材料结构动态演变过程的实时监测,是揭示电解水材料动态构效关系,解析催化反应机理的关键。本文介绍了原位电化学拉曼表征技术的基本原理,重点综述了其在催化材料相结构演变、表面活性位点和界面水分子行为中的最新进展,阐述了电解水催化材料在服役过程中结构演变与性能演变之间的变化规律,为实现催化材料全生命周期动态构效关系的精准构建提供了技术基础。最后,分析总结了原位电化学拉曼表征技术在电解水应用过程中存在的问题与挑战,并对先进原位电化学拉曼技术未来的发展进行了展望。Electrolyzing water to hydrogen supported by renewable energy is pivotal for achieving the goal of carbon neutrality and the development of a sustainable society in the future. However,catalytic materials often undergo complex structural evolution during the service process of electrolyzing water,which poses a great challenge to in-depth understand the reaction mechanism of the process of electrolyzing water and precise design of high-efficiency catalytic materials. The real-time monitoring of the dynamic evolution process of the catalytic material structure through in situ electrochemical Raman characterization technology is the key to reveal the dynamic structure-activity correlation of the electrolyzed water material as well as the mechanism of the catalytic reaction. This review introduces the basic principles of in situ electrochemical Raman characterization technology,focusing on the latest developments in the phase structure evolution of catalytic materials,surface active sites and the behavior of interfacial water molecules,and considers the change law between the structure and performance evolution for electrolytic water catalytic materials in service,which provides a technical basis for the accurate construction of dynamic structure-activity correlation in the full life cycle of catalytic materials. Lastly,the problems and challenges of in situ electrochemical Raman characterization technology in the application toward electrolytic water are analyzed and summarized,prospecting the future development of advanced in situ electrochemical Raman technology.
