Here, the photoelectrochemical performance of WO₃ films were enhanced by incorporating defect-rich MoO_3-x nanosheets. The WO₃ films were produced using a simple polymer-assisted deposition (PAD) method and subsequently modified with defect-rich MoO_3-x nanosheets, prepared via solvothermal synthesis, by drop-casting. Electronic microscopy revealed that WO₃ exhibited an agglomerated nano-globular structure with several fissures where the MoO_3-x nanosheets were anchored. In terms of photoelectrochemical performance, the optimal WO₃/MoO_3-x film exhibited photocurrent densities of 1.30 ± 0.12 mA cm⁻² and 3.20 ± 0.2 mA cm⁻² under solar simulator and LED 427 nm illumination, respectively, doubling the photocurrent density of bare WO₃. This enhanced performance was attributed to the formation of a type II heterojunction, which facilitates more efficient charge carrier separation and due to the catalytic enhancement for the oxygen evolution reaction provided by MoO_3-x.</p></div>","PeriodicalId":665,"journal":{"name":"Journal of Solid State Electrochemistry","volume":"29 2024","pages":"2157 - 2167"},"PeriodicalIF":2.6,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144125718","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}

The comparison of voltammetric data in Na₂SO₄ and NaOH solutions confirms that an apparent extension of the overall recharging interval observed in the former case is a general feature of various birnessites, which can be reliably explained by participation of protons in intercalation and, correspondingly, by local pH increase. This results in the shift of potential scale referred to reversible hydrogen electrode. The effect of lattice disorder induced by the increase of the average oxidation state of manganese, as well as the effect of interlayer space extension, is addressed on the basis of coulometric analysis of scan rate dependence. Rather weak effect of birnessite turbostratic distortions/Mn oxidation state on intercalation contribution to recharging is found. However, this distortion and the extension of the interlayer space favor higher intercalation reversibility at not too high scan rates. The increase of interfacial contribution to recharging by means of birnessite dispersion seems to be the most efficient way to increase the reversible recharging capacity, as this strategy can be applied to any potential interval, when the alternative strategy focused on the increase of intercalation contribution requires too low cathodic potentials, i.e., induces the risk of reductive birnessite degradation.</p></div>","PeriodicalId":665,"journal":{"name":"Journal of Solid State Electrochemistry","volume":"29 2024","pages":"2265 - 2280"},"PeriodicalIF":2.6,"publicationDate":"2025-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144125731","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}

In this study, we synthesized a bismuth (Bi)-based metal–organic framework catalyst (CAU-17) with tunable morphology to investigate the impact of structural configuration on its electrocatalytic performance for the conversion of CO₂ to formic acid. The mixed hexagonal rod-like/plate-like structures of CAU-17 (M-CAU-17) expose abundant electrochemically active sites, which significantly enhances the efficiency of CO₂ conversion. At a potential of − 0.9 V (versus RHE), M-CAU-17 achieved a maximum Faradaic efficiency (FE_max%) of about 80% for formic acid production, accompanied by a total current density of about 3.7 mA cm⁻². Furthermore, the CO₂ electrolysis performance of M-CAU-17 exhibited exceptional stability over an extended period of 32 h at − 0.9 V (vs. RHE). This prolonged stability highlights the practical applicability of M-CAU-17 as a robust catalyst for sustained CO₂ reduction. These results underscore the significant potential of M-CAU-17 in selectively and efficiently producing formic acid.

The optimal film loading was first determined according to its solid-state photophysical properties. Then, the electrochemically accessible [Ru(bpy)₂(bpy′)]²⁺ moieties were exploited in the presence of the MV²⁺ quencher alone in solution (aerated medium) to demonstrate the possible electrochemical regeneration of the photocatalyst immobilized in VMSF on ITO. This was achieved on the basis of experiments carried out by hydrodynamic amperometry at constant potential under successive sequential illumination (at 400 nm) and dark periods. Finally, the functionalized film was applied to the photoelectrocatalytic oxidation of EDTA in an oxygen-free solution containing also MV²⁺ species, thanks to the effective electrochemical regeneration of the quencher, as also evidenced by photocurrent measurements as a function of time with successive switching of light from “off” to “on” and vice versa.

This novel approach employs DES not only as a medium for electrode modification but also as a strategy for enhancing the sensor’s uniformity, stability, and electrochemical performance. The platform achieved a limit of detection (LoD) of 0.98 ng mL⁻¹, and the limit of quantification (LoQ) was 3.25 ng mL⁻¹, which is lower than previously reported HER2 ECD biosensors, and demonstrated a linear detection range of 1.0–150 ng mL⁻¹.

The characterization through cyclic voltammetry, electrochemical impedance spectroscopy, and scanning electron microscopy confirmed the enhanced properties of the DES-based copolymer films and nanostructures.
