Cyclic voltammetry (CV) and differential pulse voltammetry (DPV) performed at glassy carbon (GCE) and boron-doped diamond electrodes (BDDE) revealed that RIME undergoes irreversible, diffusion-controlled electrooxidation, optimally resolved in pH 2.0 phosphate buffer. Voltammetric and electron-transfer characteristics indicate a multi-electron oxidation process consistent with pyridine site electrooxidation, advancing mechanistic understanding of RIME at solid electrochemical interfaces. Quantitative analysis showed linear responses over 0.6–200 µM in standard solution and 1–20 µM in synthetic human serum, with limits of detection of 0.071 µM and 0.030 µM for GCE and BDDE, respectively. Recovery studies in serum matrices fell within acceptable ranges, confirming analytical accuracy, while co-existing electroactive species showed no critical interference under optimized conditions. Collectively, the findings establish an efficient electroanalytical platform for RIME determination and provide new insight into its electrooxidation pathway, supporting broader applications of electrochemistry in therapeutic drug monitoring and pharmaceutical analysis. A distinct novelty of this work lies in the synergistic integration of experimental voltammetry with advanced density functional theory (DFT) simulations. The experimentally observed irreversibility was elucidated at the atomic level; computational analysis confirmed that oxidation is driven by the formation of a nitrogen-centered radical on the imidazopyridine ring, followed by spontaneous bond elongation.</p></div>","PeriodicalId":665,"journal":{"name":"Journal of Solid State Electrochemistry","volume":"30 8","pages":"2933 - 2945"},"PeriodicalIF":3.1,"publicationDate":"2026-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148433918","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nevertheless, its application in CO₂/H₂O co-electrolysis and the underlying transport–reaction coupling mechanisms remain insufficiently understood. In this study, three biomimetic flow fields, namely leaf-shaped, spiderweb-shaped, and fishbone-shaped configurations, are proposed for SOEC. A three-dimensional multiphysics model coupling fluid flow, mass transport, heat transfer, electrochemical reactions, and charge transport is developed to systematically evaluate gas distribution uniformity, pressure drop, temperature distribution, and electrochemical performance. The results demonstrate that biomimetic flow fields significantly improve reactant distribution uniformity compared with the conventional parallel flow field. Specifically, the spiderweb-shaped flow field presents the most uniform reactant supply, with the distribution uniformity of H₂O and CO improved by 23.5% and 22.1% relative to the parallel channel, thus effectively alleviating concentration polarization and achieving the best electrochemical performance. The leaf-shaped flow field exhibits the lowest pressure drop and most stable pressure distribution, showing distinct advantages in reducing pumping power consumption. Parametric studies reveal that the optimal rib width ratio is 3:1 for the spiderweb flow field and 2:2–2.5:1.5 for the fishbone flow field. The optimal channel width for both configurations is determined to be 2 mm, corresponding to 8 channels for the spiderweb design and 16 channels for the fishbone design.

Along this direction, reversible solid oxide cell (RSOC) devices are well known for their remarkable high energy conversion efficiency by interconversion of electrical and chemical energy. Commonly RSOC has a configuration of a dense electrolyte, porous fuel and air electrode. Currently, electrolyte supported fuel cells (ESCs) attained attention as an energy conversion device owing to its ease of scaled up capacity and low production cost than anode supported fuel cells (ASCs). Double perovskite oxides are well known for having excellent structural stability and catalytic activity, arising from their mixed ionic-electronic conductivity, which makes them promising electrodes for solid oxide cell applications. Thus, they can be used as air electrode as well as for electrolyte supported symmetric cells which require inimitable properties, like high electrocatalytic activity for reduction of oxygen and oxidation of fuel. Nevertheless, it is essential to acknowledge that, despite the bright promise that RSOC technology holds, it is currently in its nascent developmental stages and continues to grapple with a series of formidable challenges. This paper explores the research background and working principles of reversible solid oxide fuel cell (RSOFC) and provides a detailed overview of the current research status on electrolyte, and oxygen electrode materials, for ESCs as air electrode and symmetrical cell configurations.
