摘要

利用可再生能源进行水分离制氢是实现双碳目标的关键一步。然而,由于对催化活性位点的精确定位和实际反应条件下催化剂复杂的结构演化缺乏清晰的认识,揭示水分离的电催化反应机理仍是一项挑战。原位电化学拉曼表征技术可以实时动态监测催化剂的结构演变,揭示催化剂在反应过程中的动态结构-性能关系,探索催化反应机理。本文重点从催化剂表面活性位点、界面水分子行为和电催化剂结构演化等方面综述了原位电化学拉曼表征技术的最新发展。同时还展望了先进原位电化学拉曼技术的未来发展前景。

Revealing the Electrocatalytic Reaction Mechanism of Water Splitting by In Situ Raman Technique

Using renewable energy for water splitting to produce hydrogen is a crucial step toward achieving the dual carbon goals. However, due to the lack of a clear understanding of the precise localization of catalytic active sites and the complex structural evolution of catalysts during actual reaction conditions, there is still a challenge to reveal the electrocatalytic reaction mechanism of water splitting. In situ electrochemical Raman characterization technique can dynamically monitor the structural evolution of catalysts in real time, reveal the dynamic structure-performance relationship of catalysts during the reaction process, and explore the catalytic reaction mechanism. This paper focuses on reviewing the latest developments in in situ electrochemical Raman characterization technology in terms of active sites on catalyst surfaces, the behavior of interfacial water molecules, and the structure evolution of electrocatalysts. The future development prospect of advanced in situ electrochemical Raman technology is also prospected.
