Herein, we propose a dual-engineering strategy to stabilize Ru-based catalysts by synergizing the oxygen vacancy site-synergized mechanism-lattice oxygen mechanism (OVSM-LOM) with Ru–N bond stabilization. The engineered RuO<sub>2</sub>@NCC catalyst exhibits exceptional OER performance in 0.5 M H<sub>2</sub>SO<sub>4</sub>, achieving an ultralow overpotential of 215 mV at 10 mA cm<sup>–2</sup> and prolonged stability for over 327 h. The catalyst delivers 300 h of continuous operation at 1 A cm<sup>–2</sup>, with a negligible degradation rate of only 0.067 mV h<sup>–1</sup>, further demonstrating its potential for practical application. Oxygen vacancies unlock the OVSM-LOM pathway, bypassing the sluggish adsorbate evolution mechanism (AEM) and accelerating reaction kinetics, while the Ru–N bonds suppress Ru dissolution by anchoring low-valent Ru centers. Quasi-in situ X-ray photoelectron spectroscopy (XPS), X-ray absorption spectroscopy (XAS), and isotopic labeling experiments confirm the lattice oxygen participation with *O formation as the rate-determining step. The Ru–N bonds reinforce the structural integrity by stabilizing low-valent Ru centers and inhibiting overoxidation. Theoretical calculations further verify that the synergistic interaction between O<sub>Vs</sub> and Ru–O(N) active sites optimizes the Ru d-band center and stabilizes intermediates, while Ru–N coordination enhances structural integrity. This study establishes a novel paradigm for designing robust acidic OER catalysts through defect and coordination engineering, bridging the gap between activity and stability for sustainable energy technologies.</p>","PeriodicalId":33706,"journal":{"name":"Carbon Energy","volume":"8 1","pages":""},"PeriodicalIF":24.2,"publicationDate":"2025-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cey2.70124","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146007210","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During air ingress accidents, core graphite components undergo severe oxidation, threatening structural integrity. Therefore, understanding the oxidation behavior of nuclear graphite is essential for reactor safety. The influence of oxidation involves multiple factors, including temperature, sample size, oxidant, impurities, filler type and size, etc. The size of the filler particles plays a crucial role in this study. Five ultrafine- and superfine-grained nuclear graphite samples (5.9–34.4 μm) are manufactured using identical raw materials and manufacturing processes. Isothermal oxidation tests conducted at 650°C–750°C are used to study the oxidation behavior. Additionally, comprehensive characterization is performed to analyze the crystal structure, surface morphology, and nanoscale to microscale pore structure of the samples. Results indicate that oxidation behavior cannot be predicted solely based on filler grain size. Reactive site concentration, characterized by active surface area, dominates the chemical reaction kinetics, whereas pore tortuosity, quantified by the structural parameter <i>Ψ</i>, plays a key role in regulating oxidant diffusion.

In this study, we sought to enhance the performance of this Basic-LPEG by introducing Ag nanoparticles/graphene oxide (AgNPs/GO) composite units (NP-LPEG), creating upgraded harvesting device. Specifically, by depositing the AgNPs/GO units twice onto the Basic-LPEG, we observed an increase in output voltage and current from 241 mV and 3.1 µA to 310 mV and 9.3 µA, respectively, under a solar simulator. The increase in electrical output directly correlated with the intensity of the light pressure impacting the PZT, as well as matched the Raman measurements, finite-difference time-domain simulations, and COMSOL Multiphysics Simulation. Experimental data revealed that the enhancement in electrical output was proportional to the number of hot spots generated between Ag nanoparticles, where the electric field experienced substantial amplification.
