Bipolar electrochemistry provides the possibility of depositing electrically conducting polymers controlled through the (shaped) electric field distribution. A second advantage is that electrochemistry can be performed in electrolyte-free media potentially removing the “interfering” effect of added electrolyte. Here, poly(3,4-ethylenedioxythiophene) (PEDOT) films have been deposited on bipolar electrodes directly in ultrapure water. Significantly, the deposition patterns cannot be fully explained using a linear change in the solution-phase potential, which is a common assumption for bipolar electrochemical systems. 3D finite element modeling and diffusive mass transport considerations have been combined to map the electric field distribution in this very low conductivity medium and demonstrate that homogenous rather than heterogeneous electron transfer is likely to play an important role in polymer deposition. Moreover, modeling predictions were compared to electrochemical impedance and cyclic voltammetry results and non-linear behaviours qualitatively matched, through film capacitances, and deposition patterns. The proposed framework opens up significant opportunities for the template-free deposition of various electroactive materials on bipolar electrodes in low-conductivity solutions.","PeriodicalId":142,"journal":{"name":"ChemElectroChem","volume":"12 6","pages":""},"PeriodicalIF":3.5,"publicationDate":"2025-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/celc.202400506","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143639045","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}

Herein, two molecular hybrids: N-(4-chlorophenyl)-4-(3,5-dimethyl-1H-pyrazol-1-yl)-6-morpholino-1,3,5-triazin-2-amine (1) and 4-(3,5-dimethyl-1H-pyrazol-1-yl)-N-(4-methoxyphenyl)-6-morpholino-1,3,5-triazin-2-amine (2) were prepared and characterized. Corrosion inhibition efficiencies of C-steel in acid were evaluated using weight loss, impedimetric, and potentiometric techniques, complemented by computational calculations. The inhibition efficiency (%IE) was 96.5 % for inhibitor (1) and 99.2 % for (2) at 100 ppm (0.26 mM). The inhibitors functioned as mixed-type corrosion inhibitors, effectively protecting the steel surface, as demonstrated by scanning electron microscopy (SEM). Inhibitors (1) and (2) followed Temkin and Langmuir adsorption model respectively. Moreover, density functional theory (DFT) for the neutral and protonated forms in both gaseous and aqueous phases, revealed that derivative (2), incorporating methoxy group, exhibited greater inhibition efficiency on a metal surface compared to derivative (1) incorporating Cl-(electron-withdrawing group). This is attributed to the electron-donating effect of the methoxy group in (2), in consistence with the experimental results. Additionally, MC simulations indicated a higher value of ΔEads/ΔNi associated with the metal adsorbate interaction for derivative (2), and thus more favorable and stable adsorption on the metal surface. This stronger interaction contributed significantly to its superior corrosion inhibition performance compared to derivative (1).","PeriodicalId":142,"journal":{"name":"ChemElectroChem","volume":"12 7","pages":""},"PeriodicalIF":3.5,"publicationDate":"2025-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/celc.202400515","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143770119","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}

The Co₃O₄-NDs and MLG-CuNPs were prepared via hydrothermal method and low-pressure chemical vapor deposition (LPCVD) technique, respectively. The related material characterizations of MLG-Cu/Co₃O₄-NDs are well investigated by scanning electron microscopy, high-resolution transmission electron microscopy, X-ray diffraction, Raman spectroscopy, and UV–vis spectroscopy. Photocatalytic carbon dioxide (CO2) reduction tests revealed that the carbon monoxide (CO) was identified as the primary product, accompanied by a small amount of methane (CH₄). The photocatalysis performance of MLG-Cu/Co₃O₄-NDs exhibited a total yield that was 2.59 and 3.52 times higher than those of MLG-CuNPs and Co₃O₄-NDs, respectively. The superior performance of MLG-Cu/Co₃O₄-NDs is attributed to the synergistic effects of Co₃O₄-NDs and MLG-CuNPs, as well as the LSPR effect of CuNPs. Additionally, the hierarchical heterostructure facilitates efficient electron-hole pair separation, thereby enhancing overall photocatalytic efficiency. This study highlights the potential of combining metal oxides with conductive materials (i. e., graphene and copper) to develop highly active and stable photocatalysts for sustainable CO₂ conversion.","PeriodicalId":142,"journal":{"name":"ChemElectroChem","volume":"12 7","pages":""},"PeriodicalIF":3.5,"publicationDate":"2025-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/celc.202400689","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143770522","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}

Nevertheless, its behavior towards the aluminum (Al) current collector and stainless-steel (SUS) coin cell parts limits its application under operating conditions requiring potentials higher than 3.9 V vs. Li|Li+. Using a mixture of organic carbonate-based solvents, various functional additives, and LiPF6 lithium salt concentrations up to 1.0 M, the instability issue of the Al current collector in the presence of LiFSI is avoided. However, stainless-steel dissolution remains, being confirmed by both potentiodynamic measurements and SEM morphology investigations of the coin cell components after linear sweep voltammetry measurements carried out to 5.0 V. The results also indicate that the amount of stainless-steel dissolution is influenced by both the LiFSI amount in the electrolyte and the quality (grade) of stainless-steel used. Using Al-coated SUS 316L coin cell parts and/or high concentration electrolytes (HCE) with LiFSI (≈4 M LiFSI), the observed stainless-steel dissolution process can be fully avoided, allowing the evaluation of the electrochemical performance of LMR cathodes with μ-Si anodes in LiFSI-based electrolytes.","PeriodicalId":142,"journal":{"name":"ChemElectroChem","volume":"12 6","pages":""},"PeriodicalIF":3.5,"publicationDate":"2025-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/celc.202400632","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143638845","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 context, here, current state of research and advanced scientific understandings of employing Copper for NO₃−RR are succinctly, but comprehensively, presented while focusing on its design strategies to enhance the electrocatalytic performance. First, the NO3−RR reaction mechanisms taking place at the surface of copper are described, followed by a discussion of its unique attributes in facilitating ammonia electrosynthesis. Then, various electrocatalyst fabrication routes and designing strategies are reviewed, emphasizing the role of the evolved structure, morphology, textural properties and surface chemistries in improving the reaction kinetics. Nanostructuring, facet and defect engineering, support, doping, alloying, heterojunction and the role of single active catalysts (SACs) centers as the key parameters for enhanced electrocatalytic behavior are highlighted.","PeriodicalId":142,"journal":{"name":"ChemElectroChem","volume":"12 7","pages":""},"PeriodicalIF":3.5,"publicationDate":"2025-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/celc.202400482","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143770217","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}

Traditional assays for CRP detection, like ELISA and immunoradiometric assays, are costly, time-consuming, and require large sample volumes. Aptasensors are becoming increasingly popular for MI diagnosis due to their affordability, simplicity, and potential for point-of-care use. In this study, an electrochemical aptasensor incorporating mercaptosuccinic acid-capped nickel selenide quantum dots (MSA-NiSe2 QD) were developed for CRP detection. The amine-modified aptamer was immobilized on the MSA-NiSe2 QD using EDC/NHS coupling chemistry. Chronocoulometric measurements showed high selectivity towards CRP in phosphate buffer, with a linear range of 10–110 pg/mL and a detection limit of 2.80 pg/mL. Cross-reactivity experiments confirmed the aptasensor's high selectivity for CRP. Testing in human serum samples demonstrated recovery rates of 94–100.5 %, indicating its suitability for clinical diagnostics. Validation studies with a commercial CRP ELISA kit showed the aptasensor's superior sensitivity in both physiological buffer and human serum.","PeriodicalId":142,"journal":{"name":"ChemElectroChem","volume":"12 7","pages":""},"PeriodicalIF":3.5,"publicationDate":"2025-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/celc.202400667","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143770060","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}
