Abstract

Molecular oxygen redox electrocatalysis involves oxygen reduction and evolution as core reactions in various energy conversion and environmental technology fields. Strong metal-support interactions (SMSIs) based nanomaterials are regarded as desirable and state-of-the-art heterogeneous electrocatalysts due to their exceptional physicochemical properties. Over the past decades, considerable advancements in theory and experiment have been achieved in related studies, especially in modulating the electronic structure and geometrical configuration of SMSIs to enable activity, selectivity, and stability. In this focuses on the concept of SMSI, explore their various manifestations and mechanisms of action, and summarizes recent advances in SMSIs for efficient energy conversion in oxygen redox electrocatalysis applications. Additionally, the correlation between the physicochemical properties of different metals and supports is systematically elucidated, and the potential mechanisms of the structure–activity relationships between SMSIs and catalytic performance are outlined through theoretical models. Finally, the obstacles confronting this burgeoning field are comprehensively concluded, targeted recommendations and coping strategies are proposed, and future research perspectives are outlined.

异相氧电催化中的强金属-支持物相互作用
分子氧氧化还原电催化涉及氧的还原和进化,是各种能源转换和环境技术领域的核心反应。基于强金属-支撑相互作用(SMSIs)的纳米材料因其卓越的物理化学特性而被视为理想的、最先进的异质电催化剂。过去几十年来,相关研究在理论和实验方面都取得了长足的进步,尤其是在调节 SMSIs 的电子结构和几何构型以提高其活性、选择性和稳定性方面。本文重点介绍了 SMSI 的概念,探讨了它们的各种表现形式和作用机制,并总结了 SMSI 在氧氧化还原电催化应用中实现高效能量转换的最新进展。此外,还系统阐述了不同金属和支持物的物理化学性质之间的相关性,并通过理论模型概述了 SMSI 与催化性能之间结构-活性关系的潜在机制。最后,全面总结了这一新兴领域所面临的障碍,提出了有针对性的建议和应对策略,并概述了未来的研究前景。
