The efficient catalysis of the acidic oxygen evolution reaction (OER) has always been a technological bottleneck that needs to be overcome. This article reviews the latest research progress in this field in recent years. Firstly, the article analyzes the two classic OER reaction mechanisms, adsorbate evolution mechanism (AEM) and lattice oxygen mechanism (LOM), finds that the latter may have a lower reaction energy barrier but is less stable. This provides a theoretical basis for designing catalysts with both high activity and stability. Subsequently, the article reviews recent advancements in noble, non-noble metals, and carbides catalysts, highlighting that optimizing composition and electronic structures is crucial for enhancing catalytic performance. The article also illustrates the implementation pathways of these strategies with specific examples. These innovative designs not only significantly enhance catalytic performance but also greatly improve stability, injecting new momentum into the commercial application of green hydrogen production. In summary, this article comprehensively discusses the innovative pathways of acidic OER catalysts from mechanism exploration to case analysis, and will undoubtedly provide an important reference for further breakthroughs in this field.","PeriodicalId":142,"journal":{"name":"ChemElectroChem","volume":"12 8","pages":""},"PeriodicalIF":3.5,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/celc.202400559","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143826853","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among these technologies, seawater electrocatalysis has garnered increasing attention as a high-efficiency and environmentally friendly energy conversion approach. This review summarizes recent advancements in seawater electrocatalysis for energy and resource extraction, covering the reaction mechanisms for hydrogen production via seawater electrolysis and progress in electrocatalytic materials. Specifically, we discuss the development of materials based on non-precious metals, precious metals, nonmetals, and bifunctional electrocatalysts. Additionally, the electrocatalytic conversion of inorganic pollutants (e. g., hydrazine, sulfides) and organic compounds (e. g., urea, microplastics) in seawater is reviewed, emphasizing its significance for marine resource utilization and environmental remediation. We also explore electrochemical strategies for extracting valuable metal ions, such as calcium, magnesium, uranium, and lithium, abundant in seawater. Although seawater electrocatalysis faces challenges in terms of cost and technical scalability, advancements in technology and interdisciplinary collaboration offer promising prospects for its commercialization in energy and resource extraction, with the potential to make substantial contributions to sustainable development.","PeriodicalId":142,"journal":{"name":"ChemElectroChem","volume":"12 9","pages":""},"PeriodicalIF":3.5,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/celc.202400696","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143905070","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, the electrochemistry of isolated carbon coated particles of both anode materials were for the first time studied using scanning electrochemical cell microscopy (SECCM). Interestingly, stochastic current event observations were made possible because of the small electrochemical cell created by SECCM and were designated as potential-driven stochastic events (PDSEs). The PDSEs were especially prominent in TNO compared to LTO. Metrics for judging the frequency and intensity of PDSEs were developed to compare the impact of different C-rates, particle masses and sizes of SECCM landings. The frequency and/or intensity of PDSEs increases with higher C-rates and larger overpotentials. Possible theories for the PDSEs were explored, including droplet electrowetting/spreading, gas evolution, (de)lithiation mechanisms, mass transfer limitations and inter-/intra- particle cracking. We speculate that the propensity of TNO to undergo PDSEs as compared to LTO is mainly related to the fact that TNO is known to crack extensively during cycling.","PeriodicalId":142,"journal":{"name":"ChemElectroChem","volume":"12 8","pages":""},"PeriodicalIF":3.5,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/celc.202400640","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143826711","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we study the electrooxidation of 2-propanol in alkaline electrolyte, on various commercially available carbon-supported mono- and bi-metallic noble metal nanoparticles. We use voltammetry to compare the activity of different catalysts, and we combine a flow cell with real-time analytics to monitor the products of the reaction and the dissolution of metal atoms in the presence and absence of 2-propanol. While acetone if formed on all catalysts, our results show that the onset potential is the lowest for PtRu/C, Rh/C and PdRh/C, but the oxidation current for the latter reaches a much higher value before the surface is passivated, suggesting that PdRh/C would be preferred in an alkaline fuel cell that is fed with 2-propanol. Online dissolution monitoring suggests that the anode in a 2-propanol fuel cell should not be exposed to potentials above ca. +0.8 V during transient operation, i. e., during startup/shutdown conditions, to prevent dissolution of palladium and rhodium from the catalyst surface.","PeriodicalId":142,"journal":{"name":"ChemElectroChem","volume":"12 9","pages":""},"PeriodicalIF":3.5,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/celc.202400699","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143904921","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, Bi2Se3 nanosheets were grown in-situ directly on a carbon cloth and adopted as an interlayer in lithium–sulfur batteries to accelerate sulfur chemistry kinetics. The topological phase of Bi2Se3 can effectively anchor soluble sulfur species, whereas the conductive carbon cloth provides electron transport pathways for the adsorbed polysulfides. Such a synergetic effect between the topological phase and conductive network impedes the severe shuttle effect of lithium polysulfides and accelerates the sulfur electrochemical redox reaction. Benefiting from such merits, a significantly improved specific capacity of 505 mAh g−1 at 4 C and cycling stability beyond 100 cycles with an average capacity decay rate of 0.16 % per cycle at 0.2 C was achieved when the interlayer was adopted in lithium–sulfur batteries.

The operating principle of RRDEs is that products of the disk electrode reaction – the rate of which may be influenced by rotation – move to the ring by forced convection, where they participate in an additional electrochemical reaction and will thus be detected. In contrast to classical RRDE experiments, where potentiostatic control is applied to at least one of the electrodes, new techniques were developed in the past decade that utilized dynamic potential control of both electrodes at the same time. The method of “dual dynamic voltammetry” (DDV) has since been applied to study the mechanism of electrochemical processes from electrocatalytic reactions involving dissolved species (such as oxygen reduction) to the study of metal corrosion and polymer degradation phenomena.
