Abstract

Electrochemical water splitting represents a promising technology for green hydrogen production. To design advanced electrocatalysts, it is crucial to identify their active sites and interpret the relationship between their structures and performance. Materials extensively studied as electrocatalysts include noble-metal-based (e.g., Ru, Ir, and Pt) and non-noble-metal-based (e.g., 3d transition metals) compounds. Recently, advancements in characterization techniques and theoretical calculations have revealed novel and unusual active sites. The present review highlights the latest achievements in the discovery and identification of various unconventional active sites for electrochemical water splitting, with a focus on state-of-the-art strategies for determining true active sites and establishing structure–activity relationships. Furthermore, we discuss the remaining challenges and future perspectives for the development of next-generation electrocatalysts with unusual active sites. By presenting a fresh perspective on the unconventional reaction sites involved in electrochemical water splitting, this review aims to provide valuable guidance for the future study of electrocatalysts in industrial applications.

具有特殊活性位点的先进电催化剂用于电化学水分解
电化学水分解是一种很有前途的绿色制氢技术。为了设计先进的电催化剂,确定其活性位点并解释其结构与性能之间的关系至关重要。作为电催化剂广泛研究的材料包括贵金属基(如Ru、Ir和Pt)和非贵金属基(如3d过渡金属)化合物。最近,表征技术和理论计算的进步揭示了新的和不寻常的活性位点。本文综述了电化学水分解中各种非常规活性位点的发现和鉴定的最新成果,重点介绍了确定真正活性位点和建立构效关系的最新策略。此外,我们还讨论了具有特殊活性位点的下一代电催化剂的发展面临的挑战和未来的前景。本文综述了电化学水分解中涉及的非常规反应位点,旨在为今后电催化剂的工业应用研究提供有价值的指导。
