However, the development of highly efficient and cost-effective catalysts for the oxygen evolution reaction (OER) remains a significant challenge, particularly at the industrial scale. This report explores a newly discovered pathway, the oxide path mechanism (OPM) for OER—mechanism involving the oxide formation and evolution during the reaction, emphasizing its potential to overcome existing limitations. OPM enables direct O─O coupling without oxygen vacancies, offering superior stability. We detail both classical and innovative in-situ characterization techniques that are central to unraveling the OER mechanism. The advanced in-situ electrochemical techniques, such as inductively coupled plasma mass spectroscopy, X-ray photoelectron spectroscopy, and Mössbauer spectroscopy, coupled with in-situ structural analyses, provide crucial insights into the catalyst surface, the electrode-electrolyte interface and the kinetics of OER. This review provides a systematic analysis integrating classical electrochemical methods with advanced in-situ/operando techniques, specifically focusing on understanding OPM. While numerous studies have examined individual characterization methods, this study systematically integrates traditional electrochemical approaches with in-situ and operando techniques, offering critical insights into their complementary roles in elucidating reaction pathways. The integration of these methodologies provides unprecedented understanding of catalyst behavior under operational conditions, guiding the rational design of next-generation OER catalysts. Furthermore, we discuss essential standardized test toolkits and protocols, such as those for rotating disk electrode and membrane electrode assembly, which are vital for ensuring reproducibility and scalability in OER catalyst research.</p>","PeriodicalId":33706,"journal":{"name":"Carbon Energy","volume":"8 3","pages":""},"PeriodicalIF":24.2,"publicationDate":"2026-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cey2.70067","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147669031","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}

Liquid organic hydrogen carriers (LOHCs) emerge as a transformative technology by combining high hydrogen capacity, excellent stability, and seamless integration with existing fuel infrastructure, enabling large-scale, long-distance hydrogen logistics. Despite these merits, challenges in dehydrogenation kinetics and catalyst instability impede practical deployment. Herein, we present a comprehensive mechanistic review of dehydrogenation pathways across diverse LOHC platforms, including cyclohexane, methylcyclohexane, decalin, dodecahydro-N-ethylcarbazole, perhydro-dibenzyltoluene/benzyltoluene, bicyclohexyl, and indole-based LOHCs. Compared with previous reviews, this study integrates geometric and electronic effects across multiple LOHC systems to identify cross-cutting structure–activity principles. Building on this framework, it further reveals reactant-dependent rules for active-site regulation, where the molecular architecture of hydrogen carriers critically determines the required catalyst characteristics. This perspective establishes a unified framework that links molecular descriptors to coordination-specific active sites, thereby advancing precision catalyst design for next-generation LOHC technologies.</p>","PeriodicalId":33706,"journal":{"name":"Carbon Energy","volume":"8 3","pages":""},"PeriodicalIF":24.2,"publicationDate":"2026-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cey2.70146","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147668044","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}

Interestingly, during the discharging process, the Na⁺ is inserted into FeS₂ to generate Na₂S, as well as the unique electrochemical reaction between S₂–FeNC and Na⁺ to form Na₂S.
