The presence of free-electron gas in electrides increases the flexibility in regulating its physical properties. Here, we systematically investigate the electronic and magnetic properties of monolayer Hf₂S via N-atom adsorption. We find that one-side-coverage N atoms can regulate the system to change from an antiferromagnetic metal to a ferromagnetic half-metal. The physical origin of the ferromagnetic property can be elucidated by the Stoner mechanism. Notably, two-side-coverage N atoms will further transform the system to a nonmagnetic semiconductor with large valley splitting at the K and K’ valleys. When applied an in-plane electric field, the valley Hall and spin Hall effects occurred due to optical excitation and charge doping. With these flexible properties, N-absorbed monolayer Hf₂S exhibits significant potential applications in future electronic, spintronic, and valleytronic devices.","PeriodicalId":247,"journal":{"name":"Applied Surface Science","volume":"91 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143660555","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 paper, we report an inorganic anion regulation strategy to tune different exposed crystal planes of hexagonal ZnIn₂S₄, while modifying them with h-BN cocatalyst to form van der Waals heterojunction (vdWH) and reduce the photocorrosion, thereby boosting the photocatalytic hydrogen evolution activity. Consequently, ZnIn₂S₄(102)-20BN (ZIS-20BN) photocatalysts showed a remarkable photocatalytic H₂ production performance of 3.61 mmol/g_cat/h with a 10 W LED as the light source, 1.64 times higher than that of ZnIn₂S₄(102) (ZIS-(102)). Moreover, characterization and density functional theory calculations demonstrated that ZIS-(102) exhibited the lowest work function and the introduction of an appropriate amount of h-BN induced the formation of the van der Waals heterostructure, which are conducive to the improvement of the photocatalytic hydrogen evolution activity and stability. Therefore, this study provides a new feasible option for the rational design of heterojunction photocatalysts utilizing specific crystal planes and non-noble metal cocatalysts to achieve efficient photocatalytic production of hydrogen.","PeriodicalId":247,"journal":{"name":"Applied Surface Science","volume":"32 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143660922","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 work, hierarchical porous (HP) Ce-UiO-66 loaded Ni nanoparticles (NPs) catalysts were prepared based on the soft template method and liquid-phase in situ reduction method. The introduction of mesopores into Ce-UiO-66 can effectively enhance the transfer and adsorption of the substrate, and Ni NPs act as the main active centers. Furthermore, the modulation of the electronic structure of Ni NPs and the promotion of Ce-Ni interaction were effectively achieved by changing the in-situ deposition conditions. With a low loading of 3 wt% Ni NPs, the prepared 3Ni/HP-UiO-66 catalysts could achieve the observed complete DCPD conversion and 100 % selectivity of THDCPD within 1 h and retained good cycling stability. The results demonstrated preferential adsorption and hydrogenation of the norbornene ring, confirming the reaction pathway of the 3Ni/HP-UiO-66 catalyst for the hydrogenation of DCPD.

The electrochemical oxidation and reduction of uric acid at the electrode–electrolyte interface were facilitated by the electrocatalytic behaviour of CuO nanopebbles. Upon employing differential pulse voltammetry, the fabricated electrode detected uric acid over a broad linear range of 0.1–1.2 mM with a high sensitivity of 0.020 µA µM⁻¹ and a low limit of detection of 28.2 nM. The developed electrode offers high stability over a period of 14 days with good repeatability (1.61 % RSD) and reproducibility (2.27 % RSD). Finally, the fabricated electrode was tested to quantify the spiked uric acid concentrations in synthetic urine samples to analyse the practical ability of the electrode in real-world analysis, and the recovery results (99.4–100.7 %) were satisfactory.

This study introduces a novel nanocontainer, BTA-ZIF-8@Ce-MMT, for the active corrosion protection of carbon steel. In this design, zeolitic imidazolate frameworks (ZIF-8) containing 1H-benzotriazole are in-situ grown on cerium ion-intercalated montmorillonite. The dual inhibitor-loaded nanocontainers exhibit superior on-demand inhibitor release properties, where the cerium ions and BTA molecules effectively mitigate corrosion reactions at the cathodic and anodic sites, respectively. Potentiodynamic polarization measurements demonstrated that addition of 1 g/L of BTA-ZIF-8@Ce-MMT reduced the corrosion current density (i_corr) of Q235 carbon steel immersed in 3.5 wt% NaCl solution from 3.389 to 1.541 μA·cm⁻², resulting in a maximum inhibition efficiency of 67.6 %. Electrochemical impedance spectroscopy (EIS) analysis of the bare carbon steel surface further indicated that dual inhibitor system provided synergistic corrosion inhibition and enhanced interfacial corrosion resistance (R_ct). When incorporated into a waterborne epoxy matrix, BTA-ZIF-8@Ce-MMT nanocontainers significantly improved the anticorrosive stability of the coatings. After 28 d of immersion in a saline solution, the impedance modulus of the coating at 0.01 Hz (|Z|_{0.01 Hz}) remains at 5.12 × 10⁹ Ω cm², nearly two orders of magnitude higher than that of the pure epoxy coating. Additionally, the adhesion strength of the coating declined by only 50.8 % after two weeks of salt spray test. This enhanced performance is contributed by the synergistic effects of montmorillonite, cerium ions, and 1H-benzotriazole (BTA) molecules. Together, these components establish a robust anticorrosion mechanism, which includes an extended diffusion pathway for corrosive media via the flake-structured MMT, the formation of protective cerium hydroxide or cerium oxide films, and acid-responsive BTA release from the ZIF-8 frameworks. This study for the first time introduces a dual-inhibitor strategy for modifying montmorillonite with functional MOF structures, offering a promising approach to improving the corrosion protection of epoxy coatings on Q235 mild steel.","PeriodicalId":247,"journal":{"name":"Applied Surface Science","volume":"97 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143653726","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}

Several pretreatments were tested, including mechanical grinding, alkaline etching, and acid desmutting, and combinations therein. Zr-based conversion coatings were deposited on aluminum (AA2024-T3) from a solution of 0.01 M Zr⁴⁺. The corrosion behavior of the pre-treated and coated alloys was examined using potentiodynamic polarization in sodium chloride solution. The results showed that acid desmutting in nitric acid can cause localized corrosion in the form of selective magnesium dealloying and alkaline trenching around the S-Al₂CuMg particles that continued during deposition and can compromise the corrosion protection. Alkaline etching in a sodium hydroxide solution resulted in removal of some of the larger intermetallic particles and increased the deposition rate but resulted in a cracked coating with inadequate adhesion. Desmutting in weak acid did not cause any trenching during the pretreatment and deposition. However, uneven and cracked deposition of the coating on intermetallic particles compromised the corrosion protection. These results show the benefits and limitations of common pretreatments and can lead to the development of improved pretreatment procedures and corrosion protection.","PeriodicalId":247,"journal":{"name":"Applied Surface Science","volume":"55 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143653725","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}
