The hierarchical surface roughness and excellent conductivity of Co/N-CNFs, combined with their uniformly dispersed Co sites, facilitate exceptional electrocatalytic performance toward dopamine oxidation. Electrochemical measurements demonstrated that the Co/N-CNFs composite exhibited outstanding performance for dopamine sensing, featuring a broad linear response range from 1 to 1000 µM and an exceptionally low detection limit of 0.13 µM. Moreover, the sensor exhibited remarkable stability, excellent anti-interference capability, and high accuracy in actual sample analysis.

The latter are used to calculate the Nernst-Einstein approximation to the conductivity which is compared to literature experimental data. Contrary to considerable experimental and computational evidence in the literature for the ILs examined, and statistical mechanics treatments of ion transport, they find that the conductivity exceeds the Nernst-Einstein estimate and suggest “exchange-mediated ion-transport” as a possible explanation for their observation. Examination of the data shows that their technique considerably underestimates the ion self-diffusion diffusion coefficients as conventionally measured by both steady and pulsed gradient spin-echo NMR and misestimates their temperature dependence.

Cyclic voltammetry tests reveal that the reduction of <i>Fe</i>(‖) to <i>Fe</i> on a glassy carbon electrode is an irreversible process controlled by diffusion, and the temperature has a significant influence on the reduction as well as diffusion kinetics of Fe(II) ions. The activation energy for Fe(II) reduction is determined to be 26.78 kJ mol^− 1. The chronoamperometry analyses indicate that the electrodeposition of iron follows a three-dimensional progressive nucleation model, which is largely independent of temperature. Additionally, it is found that deposition temperature plays a central role in controlling the surface morphology and structure of the resultant Fe coatings. In the temperature range of 323 K to 343 K, smooth and dense iron coating can be obtained. When the deposition temperature reaches 343 K, the Fe coating becomes extremely smooth and dense, and its phase structure transforms into an amorphous phase (metallic glass). This work presents a promising method for preparing dense Fe coatings with an amorphous phase due to its simplicity, non-polluting characteristics, and high efficiency.</p>\u0000 <span>AbstractSection</span>\u0000 Graphical abstract\u0000 <div><figure><div><div><picture><source><img></source></picture></div></div></figure></div>\u0000 \u0000 </div>","PeriodicalId":665,"journal":{"name":"Journal of Solid State Electrochemistry","volume":"30 7","pages":"2503 - 2519"},"PeriodicalIF":3.1,"publicationDate":"2026-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148357853","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}
