This biochar was prepared by two-step pyrolysis (TSP) using UPs (<em>Ulmus pumila</em> L. samara) with cavity structure, nitrogen and sulfur atoms, and higher cellulose and hemicellulose. UPBC-2 was prepared using the optimal dose of activator with a specific surface area of 2401 m²g⁻¹ and a pore volume of 1.984 cm³g⁻¹. Micropores in the hierarchical porous played a decisive role in the adsorption capacity of UPBC-2. Nitrogen (1.67 at. %) and sulfur (0.35 at. %) atoms were rapid adsorption sites for PPCPs, which were rapidly diffused into the interior of UPBC-2 through the hierarchical pores. The synergistic effect of pore structure and surface activity resulted in short equilibrium time (5, 7, and 5 min) and high saturation capacity (655.6, 754.0, and 601.7 mg/g) of CBZ, CQ, and DCF by UPBC-2. The adsorption capacity of UPBC-2 on PPCPs was almost independent of pH, ionic strength, coexisting ions, and adsorption–desorption cycles, but was influenced by molecular sizes and hydrophilicity of PPCPs. The dominant interaction in the adsorption process was the rapid π-electron sharing between PPCPs and graphitic N / thiophenic S.","PeriodicalId":247,"journal":{"name":"Applied Surface Science","volume":"35 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2024-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142840847","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}

The similar surface properties of arsenopyrite and chalcopyrite pose significant challenges to their separation via flotation. This study investigated the inhibitory effect of sodium hypochlorite (NaClO) on arsenopyrite and the activation mechanism of ammonium carbamate on chalcopyrite through a series of single-mineral and artificial mixed-mineral flotation experiments. Techniques employed include atomic force microscopy (AFM), scanning electron microscopy (SEM) with energy-dispersive X-ray spectroscopy (EDS), X-ray photoelectron spectroscopy (XPS), Zeta potential analysis, and adsorption experiments. The results from flotation indicated that NaClO oxidation significantly suppressed the arsenopyrite recovery to as low as 7.80%, while chalcopyrite recovery was reduced to 54.02%. Upon the addition of ammonium carbamate, the flotation recovery of chalcopyrite increased to 81.71%, while the recovery of arsenopyrite remained largely unaffected. Further analysis with AFM, SEM, EDS, Zeta potential, adsorption tests, and XPS revealed that NaClO facilitated the formation of a hydrophilic film on the surface of arsenopyrite, reducing the adsorption of the trap on the minerals, and suppressing the hydrophobicity of arsenopyrite. Conversely, ammonium carbamate did not activate arsenopyrite but enhanced the adsorption of butyl xanthate on chalcopyrite. The results indicated that the combination of NaClO and ammonium carbamate presents an effective method for the selective separation of arsenopyrite and chalcopyrite.","PeriodicalId":247,"journal":{"name":"Applied Surface Science","volume":"52 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2024-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142840820","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}

The preparation of Cu₃SbS₄ by large-scale dry chemistry is often accompanied by the generation of other copper antimony sulfide ternary phases during the heating process. By exploiting phase transitions in the crystal structure, the synthesis of nanophases can be controlled to improve the properties of the material. Different choices of the main material structure can trigger the evolution of the internal structure of the product material. In the experiment, the fusion of antimony atoms with host Cu₉S₅ crystals will preferentially produce thermally stable Cu₃SbS₄. The stepwise synthesis of Cu₃SbS₄ films from Sb-Cu₉S₅ stacked films was discovered. The influence of reaction temperatures on crystal structure, surface morphology, chemical composition of the films was investigated, and the optical and electrical properties of the films were analyzed during the alloying process. The pure Cu₃SbS₄ was obtained by heating and melting Cu₉S₅ and Sb in a sulphur vapor environment. The Cu₃SbS₄ films obtained at 450 °C have a forbidden bandwidth of 0.89 eV and a charge density of 1.39 × 10²⁰ cm⁻³. These findings provide an explanation for the phase transition and morphological changes during the synthesis of copper antimony sulphide and offer a new thinking strategy for the alloying of synthetic ternary copper-based sulphides.","PeriodicalId":247,"journal":{"name":"Applied Surface Science","volume":"258 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2024-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142840814","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}

Among these attributes, the utmost significance lies in the utilization of high-quality SERS substrates. A bifunctional platform featuring high photocatalytic activity and superior SERS activity was developed via a dual modification strategy integrating interface and doping engineering. Utilizing one-step hydrothermal method, ZnO/CeO₂ 3D porous microspheres (PMSs) with varied doping concentrations were fabricated, followed by the photodeposition of Ag nanoparticles to obtain n%M−ZnO/CeO₂/Ag PMSs (M = Ga or Mg) with enhanced catalytic degradation efficiency and SERS activity. The pronounced enhancement is primarily ascribed to the synergistic effects of the surface plasmon resonance (SPR) of Ag nanoparticles, interfacial charge transfer between ZnO, CeO₂ and Ag, and the augmented chemical interactions mediated by defects induced through doping. The optimized 6.25 %M−ZnO/CeO₂/Ag PMSs exhibited remarkable catalytic performance, decomposing rhodamine 6G (R6G) within 8 min and crystal violet (CV) within 6 min, manifesting a potent degradation activity towards organic dye molecules. Notably, the degradation efficiency remained basically unchanged following three consecutive cycles of reuse. As SERS-active substrate, the detection limit for R6G was achieved at 10⁻¹¹ M, demonstrating a fine linear relationship (R² &gt; 0.99) within a concentration range from 10⁻⁶ M to 10⁻¹¹ M. Even after three months of exposure to ambient air, the SERS activity was essentially unaffected, with a retention of 89 %. The detection threshold for the pesticide thiram was found to be as low as 10⁻⁹ M, which is significantly below the national standard. This novel bifunctional catalytic and SERS detection platform, refined through a combination of interfacial and doping modifications, holds great potential for significant applications in environmental monitoring and food safety.","PeriodicalId":247,"journal":{"name":"Applied Surface Science","volume":"30 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2024-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142840816","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}

The carbon content, ranging from 1 at.% to 58 at.%, significantly influenced the microstructure, hardness and Young modulus properties of the coatings. At lower carbon concentrations (up to 17 at.%), carbon atoms substituted nitrogen in the TiAlN lattice. However, higher levels of carbon led to the formation of TiAl(CN) nanocrystals and amorphous carbon phases. These structural changes resulted in a shift in the coating’s growth orientation from (1<!-- --> <!-- -->1<!-- --> <!-- -->1) to (200) and the presence of amorphous carbon at grain boundaries, which contributed to a steady decline in hardness and Young’s modulus. Additionally, the increased carbon content reduced the coatings’ corrosion resistance.

The findings reveal that increasing Cr and Al content enhances the density and mechanical strength of the coatings, with Cr playing a more dominant role in corrosion resistance. Coatings with 23 wt% Cr exhibited significantly better corrosion resistance than those with 13 wt% Cr, primarily due to reduced Fe₂O₃ formation and the development of a denser FeFe_2-x-yCr_xAl_yO₄ spinel layer, which effectively blocks the outward diffusion of Fe and the penetration of corrosive medium. The first principles simulation of H₂O adsorption on FeCrAl surface further verified the excellent stability and corrosion resistance of chrome-rich coating in aqueous environment. This study underscores the critical importance of Cr in optimizing FeCrAl coatings for PWR conditions, offering valuable insights for their application in nuclear systems.","PeriodicalId":247,"journal":{"name":"Applied Surface Science","volume":"85 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2024-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142832141","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}

The parameters included voltage, process time, electrolyte ratio, added distilled water concentration and temperature. The eco-friendly electrolyte used deep eutectic solvents (DES) composed of choline chloride (hydrogen bond donor, HBD) and ethylene glycol (hydrogen bond acceptor, HBA). Additionally, the effect of adding distilled water at various concentrations to the DES was investigated to promote ion diffusion. Increasing the distilled water content shortened the time required for the current density to reach a steady state during electropolishing. Distilled water, a highly polar molecule, likely weakened hydrogen bonding between the HBD and HBA, reducing electrolyte viscosity and stabilizing the dissolution reaction. Voltage had the most significant effect on surface roughness, directly influencing the thickness and microstructure of the oxide layer. Excessive voltage caused surface damage. The optimal electropolishing conditions finally determined through Taguchi robust design were 16 V voltage, 25 min process time, 35 °C temperature, an ethylene glycol ratio of 2 and a 30 % added distilled water concentration.","PeriodicalId":247,"journal":{"name":"Applied Surface Science","volume":"1 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2024-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142832097","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 presented a multi-dimensional composite electrode with multivalent Cu-based oxides designed using a simple immersion reduction method. Cu(OH)₂ nanowires and Cu₂O nanoparticles were in-situ grown on Cu foam, creating a multidimensional composite structure. Subsequently, the electrode is transformed into Cu⁺/Cu⁰ through electrochemical in-situ reduction, while the microstructure and morphology do not undergo significant changes. The electronic interactions between multivalent Cu-based oxides promoted physicochemical adsorption of NO₃^– molecules and optimize electron and proton transfer pathways. At a potential of −0.8 V (<em>vs</em>.
