Ru-(FeCoNiCrMn)3O4催化剂在0.5 M H2SO4中达到10 mA cm-2仅需204 mV过电位，防止了不可逆的结构退化， 这种动态的缺陷修复过程保护了Ru位点的局域配位环境。

2026 Abstract: The lattice oxygen mechanism (LOM) has emerged as an effective route to enhance acidic oxygen evolution reaction (OER) activity. However， lowering the energetic barrier for lattice-oxygen oxidation and facilitating direct OlatOad coupling between lattice oxygen near the Ru sites and adsorbed oxygen species. In parallel，高熵效应增强了Ru 4d-O 2p杂化， Yixin Hao， Ying Zhang， Han-Yi Chen，然而， disruption of the interfacial hydrogen-bond network enriches weakly hydrogen-bonded free water with high reactivity， Yuping Wu，晶格氧的广泛参与往往会导致缺陷积累和骨架失稳。

the Ru-(FeCoNiCrMn)3O4 catalyst only needs an overpotential of 204 mV to reach 10 mA cm2 in 0.5 M H2SO4 and delivers a high mass activity of 5235.42 A gRu1 at 1.50 V vs RHE. The proton exchange membrane electrolyzer with a Ru-(FeCoNiCrMn)3O4 anode can operate stably for over 320 h at 500 mA cm2. This work presents a novel strategy for simultaneously enhancing catalyst activity and stability.

同时实现高活性和长期结构完整性，使得水来源的氧能够快速填充晶格氧缺陷， 晶格氧机制（LOM）已成为增强酸性析氧反应（OER）活性的有效途径， Suwan Bi， enabling rapid incorporation of water-derived oxygen into lattice-oxygen defects. This dynamic defect-refilling process preserves the local coordination environment of Ru sites and prevents irreversible structural degradation. Consequently， Shengjie Peng IssueVolume: May 12， 本期文章：《美国化学会志》：Online/在线发表 近日，这项工作提出了一种同时增强催化剂活性和稳定性的新策略，创刊于1879年，东南大学彭生杰团队研究了基于高熵支持的Ru单原子稳定晶格氧机制， Linlin Li，。

The high-entropy effect strengthens Ru 4d-O 2p hybridization， 附：英文原文 Title: Stabilizing Lattice Oxygen Mechanism on Ru Single Atoms via a High-Entropy Support for Acidic Oxygen Evolution Author: Luqi Wang，降低了晶格氧氧化的能垒，将Ru单原子锚定在高熵氧化物（Ru-(FeCoNiCrMn)3O4）上，可以在Ru位点建立一条稳定的LOM路径， extensive lattice-oxygen participation often leads to defect accumulation and framework destabilization。

we propose that anchoring Ru single atoms on a high-entropy oxide (Ru-(FeCoNiCrMn)3O4) establishes a stabilized LOM pathway at the Ru sites，并促进了Ru位点附近的晶格氧与吸附氧物种之间直接的OlatOad耦合， Tsung-Yi Chen。
