Cyclic voltammetric data show that complex 1 exhibits a one-electron oxidation process, resulting in the creation of a π-cation radical. This observation is further confirmed by the analysis of the complex using FT-IR. The addition of CF3COOH (TFA) with complex 1 has resulted in the development of mono-cation with geometrical changes from square pyramidal to octahedral, which has been confirmed by UV-Vis and EPR spectra.The interaction between Complex 1 and TFA, is investigated by Non-covalent Interaction (NCI) analysis, Visual Molecular Dynamics (VMD) visualization, Electron Localization Function (ELF) analysis, and Molecular Electrostatic Potential (MEP) mapping. The vanadium atom in Complex 1 interacts with the oxygen atom in CF3COOH at a distance of 2.18 Å. NCI and RDG analyses highlight the predominant van der Waals interactions. VMD visualization confirmes these interactions with green patches. ELF analysis shows strong electronic localization around certain atoms and delocalized electron clouds.

Excess nitrite remains in the agricultural fields and foods to enter the environment, rendering it one type of typical environmental pollutant. Therefore, a simple, accurate, quick and low-cost sensor to detect nitrite is highly necessary and meaningful for public health and environmental security. In this study, bimetallic transition metal oxide nanoarray materials have been directly grown on nickel foam (NF) to afford a binder-free electrochemical sensor of Co1Ni1O/NF to determine nitrite in an amperometric mode. Unique radial needle-like nanoarray morphology was observed for the as-prepared Co1Ni1O, which was believed to offer a sufficient conductive pathway for facile electron transfer to enable quick nitrite electro-oxidation. The synergistic effect of the bimetallic Co–Ni oxide nanoarray materials of the binder-free electrochemical sensor rendered a wide linear range of 10 μM to 3.5 mM for nitrite detection, with excellent anti-interference, reproducibility and stability. The Co1Ni1O/NF also exhibited good recovery in actual lake water samples, which would be promising for its potential application under the real scenarios.","PeriodicalId":760,"journal":{"name":"Russian Journal of Electrochemistry","volume":"60 Based","pages":"1041 - 1050"},"PeriodicalIF":0.8,"publicationDate":"2025-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145121401","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Flexible supercapacitors have a lot of potential as power sources for next-generation flexible electronics since they are safer, more robust, and mechanically more stable than current batteries. This paper explains the construction of flexible cathode electrodes for supercapacitors made of EVA thermoplastic film, polyaniline, and carbon nanotubes. Herein, by combining Ethylene-vinyl acetate (EVA), Polyaniline (PANI)’s pseudo-capacitance, and the charge transport ability of carbon nanotubes (CNTs), EVA/PANI@CNT flexible films were constructed as supercapacitor cathode electrodes with brilliant electrochemical performance and elasticity. Electron beam irradiation at 100 kGy is used in crosslinking carbon nanotubes/polyaniline (PANI@CNT) composites with ethylene-vinyl acetate. These electrode materials were prepared with different concentrations of nanostructures (PANI@CNT) (50, 60, and 70%) concerning EVA thermoplastic film as a current collector. Then study the electrochemical performance of prepared conductive polymeric films without and with EBI at 100 kGy. The improvement in electrochemical performance of the flexible cathode electrodes is theoretically due to the creation of structural defects upon irradiation. Also, the structure, phase, and avascularity of as-prepared films were verified utilizing XRD, FTIR, and Raman. This study proves that optimizing the concentration of the electroactive material/current collector interface can apply faster electron transport and constitutes a powerful strategy to reinforce the electrochemical capacitive properties of supercapacitors.","PeriodicalId":760,"journal":{"name":"Russian Journal of Electrochemistry","volume":"60 Based","pages":"1133 - 1152"},"PeriodicalIF":0.8,"publicationDate":"2025-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145121466","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
