However, conventional two-dimensional gap-enhanced substrates suffer from limited analyte diffusion into nanogap caused by plasmonic material hydrophobicity. Herein, we present a V-shaped SERS substrate designed to overcome these challenges through three synergistic mechanisms: (i) three-dimensional (3D) plasmonic nanogaps, (ii) gravity-driven analyte enrichment enabling efficient aqueous-phase molecule transport, and (iii) light-trapping nanopores amplifying electromagnetic fields. By utilizing atomic layer deposition (ALD)-defined ultrathin alumina sacrificial layers, we achieved precisely tunable nanogaps (2–10 nm) between gold nanoparticles (AuNPs) and the underlying gold film within V-shaped architectures. The optimized 6 nm AuNPs-gap-Au nanostructure balances near-field intensity and aqueous analyte accessibility, achieving sub-nanomolar sensitivity for rhodamine 6G with outstanding reproducibility (RSD < 9 % across 10⁻⁹–10⁻⁵ M). Significantly, the substrate enables multiplex detection of dye pollutants (basic blue 3, malachite green, methylene blue) at sub-nanomolar level in river water, showing great potential for real-time, on-site monitoring of emerging pollutants in natural water systems.","PeriodicalId":247,"journal":{"name":"Applied Surface Science","volume":"4 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2025-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144083220","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Developing simple methods to prepare efficient bimetallic catalysts is currently a major challenge for scientists. Comparison of the catalytic activity of heterogenized monometallic and bimetallic nanocatalysts prepared by immobilizing metalloporphyrins (iron porphyrin and manganese porphyrin) or bare metals (iron chloride and manganese acetate) onto the surface of functionalized multi-walled carbon nanotubes (MWCNT-COOHs) is reported. Supported nanocatalysts are characterized using transmission electron microscopy (TEM), thermogravimetric analysis (TGA), atomic absorption spectroscopy (AAS), and Fourier-transform infrared spectroscopy (FT-IR). The catalytic study focused on the aerobic oxidation of olefins under mild conditions. The role of porphyrin ligand on the catalytic efficiency of the prepared bimetallic heterogenized nanocatalysts was compared with metal salts as well as monometallic catalysts, and the results show higher catalytic activity of bimetallic nanostructures compared to the monometallic catalysts. Although among monometallic nanohybrids, supported metalloporphyrins exhibited much higher efficiency than immobilized bare-metals; unexpectedly, the supported bare-metals show higher (or at least equal) catalytic activity compared to the porphyrin-based nanocatalyst in the case of bimetallic nanostructures. All the prepared nanocatalysts were reusable for at least four catalytic cycles.","PeriodicalId":247,"journal":{"name":"Applied Surface Science","volume":"4 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2025-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144083219","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, CS was employed as a matrix material to fabricate gel beads (Fe/Mg-CS) through cross-linking with Fe³⁺ and Mg²⁺ thereby enhancing its adsorption capacity for As(V). The Fe/Mg-CS adsorbent was thoroughly characterized, and its adsorption performance was evaluated under optimized conditions. The optimal dosage of Fe/Mg-CS was determined to be 0.06 g/L, with effective adsorption observed within a pH range of 3–7. Kinetic analysis revealed that the adsorption process followed a pseudo-second-order model, suggesting that the adsorption mechanism primarily involves complexation reactions between hydroxyl groups and As(Ⅴ). Isotherm studies indicated that the Langmuir model provided the best fit, with a maximum adsorption capacity of 147.49 mg/g. Compared to conventional powdered adsorbents, Fe/Mg-CS offers several advantages, including straightforward synthesis, ease of recycling, and high efficiency. These properties make Fe/Mg-CS a promising candidate for the remediation of As(V)-contaminated groundwater, providing a sustainable and effective solution for future water purification applications.","PeriodicalId":247,"journal":{"name":"Applied Surface Science","volume":"54 1","pages":"163443"},"PeriodicalIF":6.7,"publicationDate":"2025-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144083224","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, Ag&WS₂ composites are synthesized through controlled growth, doping, and surface anchoring/promotion strategies, enabling the modulation of ultrafast time-domain optical absorption mechanisms in WS₂. This modulation is achieved via surface plasmon resonance absorption, separated excited states, and charge transfer channels constructed by metallic components. Furthermore, density functional theory calculations and transient absorption experiments reveal interface contact charge doping, stress-induced light-medium coupling effects, and ultrafast charge transfer mechanisms. By adjusting the Ag content and contact mode, and by analyzing strain modulation at the surface/interface, precise control over ultrafast laser-induced nonlinear absorption behavior was achieved. These findings highlight the crucial role of charge transfer between excited states and exciton-phonon coupling in NLO modulation and photoelectric conversion in composite materials, along with the control mechanisms of surface-localized strain generation and charge distribution. This research provides a theoretical foundation and experimental support for the design of novel NLO materials, offering significant implications for their practical application in optoelectronic devices.","PeriodicalId":247,"journal":{"name":"Applied Surface Science","volume":"141 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2025-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144067394","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigates the role of Al sites in ZSM-5 in influencing the formation and stability of active species at the atomic level. Using Fe-based zeolites as the main object of study, detailed spectroscopic analysis combined with density functional theory (DFT) calculations showed that framework Al can reduce the dispersion resistance of exogenous Fe_xO_y particles, prevent the agglomeration of Fe species during annealing, and maximize atomically dispersed Fe as the active sites.

The samples were selectively laser-treated to reach 900 °C on the surface, just above the temperature of α-β phase transition: one batch before and one after ON. Their properties were compared with an oxynitrided sample and an untreated sample. The X-ray diffraction (XRD) analysis, electron backscatter diffraction (EBSD) indicate a phase shift towards a more α-phase and the formation of titanium oxides and nitrides. Transmission electron microscopy (TEM) studies demonstrated the formation of a compound layer consisting of nitrides modified by oxygen and phase changes in the diffusion layer.
