Flexible organic materials are considered promising SDIBs cathodes due to their tunable structures and multi-electron redox properties. However, poor solubility, low conductivity, and particle agglomeration limit their practicality. Herein, a composite poly(5, 10-diphenylphenazine)@rGO (PDPPZ@rGO) was designed for the cathode of SDIBs. The rGO matrix enhances PDPPZ's dispersibility and active surface area while providing high conductivity and mechanical stability, resulting in superior electrochemical performance. Consequently, the PDPPZ@rGO electrode demonstrates a remarkable discharge capacity of 175.8 mAh g^-1, excellent rate performance (128.9 mAh g^-1 at 40 C), and outstanding cyclic stability (capacity retention of 85.1% after 5000 cycles at 10 C). Furthermore, PDPPZ@rGO has excellent wide temperature adaptability, outputting a specific capacity of 157.7 mAh g^-1 at high temperatures of 60 °C and 145.2 mAh g^-1 at low temperatures of -20 °C. This research demonstrates the potential of organic cathode materials for rapid charge/discharge capabilities and wide temperature adaptability in SDIBs.","PeriodicalId":305,"journal":{"name":"Electrochimica Acta","volume":"22 1","pages":""},"PeriodicalIF":6.6,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143745662","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Each of the components in this tertiary system plays an important role. The exfoliated graphite provides high conductivity and adds to energy storage through double-layer capacitance. The NM-LDH is the major faradaic component, whereas the AQS adds also to the faradaic energy storage as well as separates the NM-LDH 2D layers and increases the working potential window.

The penetration of LDH and AQS was characterized using cross-section electron microscopy. The hybrid electrode exhibits a specific capacity of 612 mAh g⁻¹ at 2 mV s⁻¹ in 5 M KOH.

To regulate the lithium nucleation/deposition behavior and improve the surface properties of the andoe current collector, we utilized an Electron beam-induced deposition (EBID) system to rapidly synthesize a 200 nm thick lithiophilic zinc functional layer on the copper foil surface. The results showed that the rapid deposition effect based on EBID technology endows the zinc functionalized copper foil with an extremely low lithium nucleation overpotential (≈0 V) and abundant lithium nucleation site (C_dl=239.23 uF cm^-2). At the same time, the zinc layer has close to 100% mechanical bonding to the substrate. Compared to commercial copper foil, the current collector with a zinc-modified layer exhibits more uniform and controllable lithium deposition morphologies under various cycling numbers and lithium deposition capacities. Specifically, at a current density of 0.5 mA cm^-2, the half-cell assembled with this current collector maintains a Coulombic efficiency of up to 95% after 200 cycles, and the symmetric cell can stably cycle for over 3100 hours.

However, its remarkable stability has raised concerns about accumulation in soils and aquatic environments, garnering significant attention from the analytical community. In this report, we propose a nanoporous gold electrode with reduced graphene oxide (NPGrGO) prepared according to a mold-assisted electrodeposition method, in which the gold film was deposited simultaneously with the reduction of graphene oxide on a gold microfiber surface for CBZ determination. The NPGrGO electrode exhibited a high density of edges with graphene sheets confined within the pores in the presence of gold nanoparticles. This unique configuration significantly enhances the electrochemical surface area and the roughness factor, directly influencing electrochemical measurements. Differential pulse voltammetry results show a linear behavior in the CBZ concentration range of 1 – 200 µmol L^-1 with a limit of detection of 0.3 µmol L^-1 and a limit of quantification of 1.0 µmol L^-1. Besides, the NPGrGO sensor also revealed excellent reproducibility (4.2%), repeatability (3.7%), and selectivity toward CBZ detection in the presence of other interfering molecules or ions. Finally, as proof of concept, the NPGrGO was used to determine CBZ in river water samples. Therefore, we have demonstrated a simple and rapid method for fabricating an NPGrGO electrochemical sensor, highlighting its significant potential for applications in environmental analysis.","PeriodicalId":305,"journal":{"name":"Electrochimica Acta","volume":"32 1","pages":""},"PeriodicalIF":6.6,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143745736","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, we report on an <em>in-situ</em> electrochemical strategy for the selective synthesis of hybrid electrocatalysts using a cobalt MOF (2D-CoMOF) as a precursor for constructing electrochemical sensors to monitor the glucose oxidation reaction (GOR). By using <em>in-situ</em> Raman spectroelectrochemistry, it is demonstrated that a precise control of the applied potential during amperometric treatment of 2D-CoMOF can promote the generation of derived heterostructures in which the original MOF coexists with metal oxides and/or oxyhydroxides (MOF-MOx) with different compositions. The so-prepared electrodes exhibit high electroactive surface areas, a high number of electrocatalytically active cobalt sites and an efficient charge transport across the catalytic film. Moreover, their composition-dependent electrocatalytic performance for the glucose oxidation reaction is examined, establishing a relationship between the applied potential, the macroscopic chemical composition of the heterostructure and the electrocatalytic performance for glucose sensing. In particular, the hybrid phases consisting of Co-MOF/Co₃O₄/CoOOH display superior electrocatalytic sensing performance with a wide linear concentration range and high sensitivity. The present work emphasizes the significance that the precise control of the applied potential has on the electrochemically-assisted MOF transformation for developing highly efficient MOF-derived electrocatalysts.","PeriodicalId":305,"journal":{"name":"Electrochimica Acta","volume":"43 1","pages":""},"PeriodicalIF":6.6,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143737299","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This experimental set-up presents numerous advantages in terms of sensitivity and simplicity in characterizing charge transfer processes. In this context, one of the most widely used tools is Cyclic Voltammetry (CV) and, although the theoretical analysis of its response under FD conditions has been previously reported (especially for the thin-layer, TL, limiting behaviour), there were some gaps that hindered its application to numerous cases of interest. The treatment presented here extend the existing CV analysis to Cyclic Staircase Voltammetry (CSCV), which is indeed the real technique applied in many digital potentiostats. Moreover, the expression for the charge-potential responses under FD conditions is reported for the first time. Thus, the converted charge is directly related with the concentration of electroactive species, and it can be measured with high reliability by following adequate experimental protocols. Two different diffusive modes are considered: bounded diffusion, corresponding to absence of mass renovation at a finite distance from the electrode, and unbounded diffusion, for which a fast mass renovation at such finite distance takes place. The general analytical expressions of the current-potential and charge-potential responses are simplified under TL conditions, leading to very simple ways for determining key parameters of the systems under study. The application of this formalism to the oxidation of a metallic complex under both configurations is presented, and practical values for the operating parameters are also discussed.","PeriodicalId":305,"journal":{"name":"Electrochimica Acta","volume":"53 1","pages":""},"PeriodicalIF":6.6,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143737301","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its structure allows curcumin to interact with the hydrophobic regions of Aβ peptides, which are crucial for β-sheet formation, inhibiting Aβ aggregation and fibril formation, destabilizing existing plaques, and reducing neurotoxicity. The time-dependent structural modifications and electrochemical behaviour of human Aβ₁₋₄₀ and Aβ₁₋₄₂ peptides following their interaction with curcumin were investigated by atomic force microscopy (AFM), differential pulse (DP) voltammetry and electrochemical impedance spectroscopy (EIS). The results showed that curcumin disrupts and slows the fibrillization process by binding to specific aromatic residues of the Aβ peptides, via curcumin methoxy and hydroxy groups, hindering the conformational changes required for fibril nucleation and elongation. This targeted binding not only influences the Aβ dynamics, reducing the extent of fibrilization, but also promotes more opened configurations that enhance the electron transfer from the electroactive amino acid residues histidine H⁶, tyrosine Y¹⁰, histidines H¹³ and H¹⁴, and methionine M³⁵ to the electrode surface, due to their direct interaction with curcumin and/or their proximity to other curcumin binding sites, consistent with the curcumin inducing the formation of soluble less toxic species.
