The high fabrication costs and time constraints have driven the development of reusable substrates. Ag nanoparticles (NPs) with nanogaps are widely used as SERS substrates because of their ability to excite strong localized surface plasmon coupling. However, developing a facile method for producing reusable Ag NP SERS substrates remains challenging. In this study, we introduce a rapid and cost-effective method for mass-producing Ag NPs using a two-step process: Spin coating a self-reducing solution, followed by heating treatment. This method enables the mass production of Ag NPs with nanogaps as small as approximately 10 nm, eliminating the need for a vacuum environment, expensive equipment, or complex processing steps. The formation mechanism of Ag NPs is briefly discussed, and the key factors for successful preparation are highlighted. The resulting Ag NPs exhibit superior SERS performance, uniformity, and sensitivity. They functioned as washable and highly reusable SERS substrates, showing no significant performance loss after four ultrasonic cleaning cycles. Even after ten cycles, over 60% of the initial SERS performance was retained, demonstrating their robustness and practical applicability.</div></div>","PeriodicalId":247,"journal":{"name":"Applied Surface Science","volume":"712 ","pages":"Article 164145"},"PeriodicalIF":6.3,"publicationDate":"2025-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144710713","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}

Here, we investigate high activity catalysts composed of different ratio Pt and C elements by composition-adjustment strategy. Among the predicted four stable and metallic structures, the Pt2C monolayer with low Pt loading exhibits the highest electron occupation at the Fermi level, and owns lower adsorption energy and dissociation energy for water molecule, thereby providing a platform for investigating catalytic performance. Its HER activity is predicted to be superior to that of commercial Pt due to several key factors, i.e. Gibbs free energy, active site density, and exchange current density, which can primarily be attributed to its Janus steric configuration and excellent conductivity. Moreover, the OER overpotential is low to 0.58 V, which of the value is lower than that of Pt (111) surface and Pt monolayer.

Herein, we report an enzyme-free electrochemical voltammetric approach for selectively detecting H2O2 in drinking water employing NiFeP nanointerface for the first time. The NiFeP was synthesized via a two-pot synthesis by phosphorizing hydrothermally prepared NiFe Layered Double Hydroxides (LDH). Structural analysis revealed the disappearance of LDH-specific diffraction peaks ((0 0 3) and (0 0 6)) and the emergence of distinct NiFeP crystalline planes, confirming the successful structural conversion from NiFe-LDH to NiFeP. NiFeP nanointerface showed linear detection ranges of H2O2 (0.1–1 μM and 5–100 μM), with LODs of 0.027 μM and 1.58 μM, and sensitivities of 17.11 and 0.81 μA mM−1 cm−2, respectively. The enhanced electrochemical performance of the NiFeP system prevails in the interaction with H2O2, with substantial redox activity by reversible redox couples, compared to the NiFe LDH, where the redox couples (Ni2+/Ni3+ and Fe2+/Fe3+) are limited.

Among these, the film deposited with 60 cycles (60/ZTO) exhibited superior PEC performance, achieving a photocurrent density of 0.624 mA/cm2 at 1.23 V vs RHE. This enhanced performance is attributed to its improved crystallinity and surface morphology with an improved charge transfer mechanism.

This study proposes a novel process for fabrication of atomic-level step-terrace structure of sapphire using atmospheric pressure plasma. Firstly, microwave plasma-assisted polishing (MW-PAP) is used to rapidly reduce the roughness of the lapped surface, and then subsurface damage is repaired and the step-terrace structure is formed by plasma-enabled atomic-scale reconstruction (PEAR). Surface composition and morphology analyses have shown that based on the mechanism of hydroxyl dehydration condensation, MW-PAP can reduce the Sa roughness from 146 nm to 4.6 nm within 30 min. Subsurface characterizations indicate that during the MW-PAP process, the surface damage layer is converted into an amorphous phase and rapidly removed. The amorphous layer and sub-surface damage are repaired in the subsequent PEAR process, leading to an improvement in sapphire crystallinity. Additionally, in situ scratching experiments indicate that during the PEAR process, scratches can be healed under the influence of atomic migration due to plasma irradiation. Simultaneously, driven by the minimization of surface energy, surface atoms are induced to migrate and the step-terrace structure is formed. The plasma-based hybrid processing is conducted in an atmospheric environment, enabling the formation of step-terrace structure from lapped sapphire in approximately one hour, which is expected to enrich the manufacturing theory of high-quality substrates.</div></div>","PeriodicalId":247,"journal":{"name":"Applied Surface Science","volume":"712 ","pages":"Article 164152"},"PeriodicalIF":6.9,"publicationDate":"2025-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144701722","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}
