This study successfully prepared Se–Sb–Ag optoelectronic alloy coatings by pulse electrodeposition in deep eutectic solvents (DESs). The electrochemical behavior of SeO2, SbCl3, and Ag2SO4, in a choline chloride-ethylene glycol DES, was systematically investigated using cyclic voltammetry (CV) and chronoamperometry (CA). CV and CA results revealed an induced codeposition mechanism. The nucleation mechanism of the Se–Sb–Ag alloy coatings between −0.30 V and −0.70 V was identified as a diffusion-controlled three-dimensional (3D) instantaneous process. The effects of pulse potential on surface morphology, composition, crystal structure, and photoelectrical properties of the coatings were systematically examined. The SEM results indicated distinct potential-dependent nanostructural evolution. A moderate negative shift produced smaller secondary nanoparticles and denser, more uniform coatings, whereas an excessive negative potential led to finer but loosely packed nanograins with increased porosity and reduced compactness. The EDS results demonstrated that Ag content initially decreased and then stabilized, Sb content first increased and then declined, while Se content showed an overall increasing trend. The crystalline phases were mainly Ag, Se, Sb, and Ag2Se phases. The coatings exhibited p-type semiconducting behavior. The band gap increased from 0.66 eV to a maximum of 0.76 eV as the electrodeposition potential shifted negatively, followed by a decrease to 0.72 eV at more negative potentials. A similar trend was observed in photocurrent density, which reached a maximum of 0.24 mA/cm2 at −0.80 V. By taking advantage of the strong complexation and solvation capabilities of DESs, this work demonstrates a pulse electrodeposition route suitable for reusing semiconductor elements such as Se and Ag. The electrodeposition mechanism of Se–Sb–Ag ternary coatings was clarified, and pulse deposition in DESs was shown to enable controlled tuning of their structural and photoelectrical properties. These findings indicate that DES-based electrodeposition holds promise for the green preparation of optoelectronic semiconductor materials.

A promising dual-coping Ag,S-Cu x O/Cu foam electrocatalyst was synthesized for CO 2 RR. • The synergistic effect of Ag and S for CO 2 RR toward HCOOH and CH 3 OH was elucidated. • The Ag-S synergistic mechanism governing HCOOH and CH 3 OH formation was revealed. The electrochemical reduction of CO 2 into value-added fuels such as formic acid and methanol presents a promising approach to mitigating climate change, yet it is constrained by the rational design of efficient electrocatalysts and the understanding of structure-efficiency relationships. Here, a highly efficient Ag,S-Cu x O/Cu catalyst was developed via a facile in situ dual-doping strategy, incorporating Ag and S onto pre-oxidized copper foam. Comprehensive multimodal characterization (SEM, EDS, XRD, XPS, AES) and electrochemical measurements (LSV, EIS, GC, 1 H NMR) were conducted to elucidate the catalyst’s structural properties and CO 2 reduction performance. Results indicate that Ag/S dual doping synergistically enhances catalytic activity by reducing solution mass transfer resistance through improved catalyst nanostructures and expanding the electrochemical active surface area (ECSA). Ag incorporation effectively suppresses the competitive hydrogen evolution reaction (HER), while S incorporation lowers charge transfer resistance ( R ct ). Compared with the Cu x O/Cu foam catalyst, the Ag,S-Cu x O/Cu foam catalyst exhibits increased partial current densities for formic acid (HCOOH) and methanol (CH 3 OH) by 17.09 and 5.70 mA·cm −2 , respectively. Furthermore, the reaction pathways for the electrochemical conversion of CO 2 to HCOOH and CH 3 OH are systematically elucidated. This study proposes a dual-doping strategy to achieve sustainable CO 2 electroreduction and delivers fundamental insights into the external parameters that govern the selective formation of high-value products.

Nylon shrinkage effect generates dense SERS hotspots. • Ultrahigh sensitivity, achieving a detection limit of 10 −9 M for the probe molecule R6G. • Excellent uniformity and reproducibility, with a relative standard deviation (RSD) of 5.14% across 50 random spots. • Superior long-term stability, retaining 89.23% of the initial SERS signal after 30 days of storage. • Paste-and-peel method for in-situ CBZ detection on fruit. To address the widespread issue of carbendazim (CBZ), a common pesticide residue, on the surfaces of fruits and vegetables, our research team prepared silver nanoparticles using the sodium citrate reduction method and successfully loaded them onto a nylon membrane substrate via vacuum-assisted filtration. Subsequently, the substrate was modified with 4-mercaptobenzoic acid (4-MBA) as an internal standard signaling molecule, yielding a Nylon-Ag@4MBA flexible surface-enhanced Raman spectroscopy (SERS) substrate. The as-prepared Nylon-Ag@4MBA substrate exhibited excellent uniformity (RSD = 5.14%), a detection limit as low as 10 −9 M for the R6G probe molecule, and a signal retention rate of 89.23% after 30 days of storage. In the detection of actual samples such as apples, the recovery rates of CBZ ranged from 95.05% to 96.90% with relative standard deviations (RSDs) below 4.07%, demonstrating reliable quantitative capability. No interference was observed from common substances on the fruit peel. This study confirms the potential application of the Nylon-Ag@4MBA substrate for the on-site rapid detection of pesticide residues.

Characterized with dynamic reaction on the fly, chemically-driven microbots, the microscale embodied intelligent agents (MEIagents), have attracted tremendous attention for their ability to learn and perform tasks through interaction with surroundings. However, molecular mechanisms of how surface-engineering modulates microrobots performance remains unresolved.

Energy conversion efficiency of AgTPMbots is 30~259 times by that of AgNPs due to enhanced catalysis integrated with optimal coupling between chemical energy, interfacial interaction and fluid dynamics, as well as prompted bubble formation on concave Ag surface. With mechanical disruption, ROS, Ag + and reshaped rich O 2 microenvironment, AgTPMbot gargle shows superior active antimicrobial treatment efficiency in SD rats periodontic model as the eradication of biofilm and anaerobic pathogenic bacteria remodeling periodontal immune-metabolic homeostasis. Such surface engineering tailored mobility, interaction with surroundings and application performance of microrobots provides a molecular paradigm for engineering MEIagents.

Ag doping improves piezoelectric field and PMS/O 2 adsorption and activation. • The faster charge transfer of 2-Ag/MoS 2 boosts pollutant degradation activity. • PVDF membranes solve the recovery and reusability issues of powder catalysts. The integration of piezocatalysis with persulfate-based advanced oxidation processes holds substantial potential for pollutant remediation, yet its practical efficacy is often plagued by the limited piezoelectric field strength and low affinity of peroxymonosulfate (PMS). Herein, silver-doped layered molybdenum disulfide (Ag/MoS 2 ) was used to degrade pollutants by piezo-promoted PMS activation. The experimental results and theoretical calculations of adsorption energy, density of states (DOS) and electron localization function (ELF), clarified that Ag doping in MoS 2 plays a triple role in promoting the activation of piezoelectric driven PMS: Firstly, Ag doping can effectively improve the piezoelectric polarization field of the material. Secondly, it facilitates the adsorption and activation of oxygen-containing species such as PMS and O 2 by the catalyst. Thirdly, Ag acts as active sites and participates in the generation of reactive oxygen species (ROS). The synergistic effect promoted charge separation and reaction kinetics, significantly accelerating the activation of PMS and improving the degradation efficiency of ORZ. Furthermore, combined with the Fukui function calculations and liquid chromatography-mass spectrometry (LC-MS) measurements, the potential degradation pathways of ORZ during the reaction process were systematically revealed. Under ultrasonic (US) conditions, the piezoelectric catalytic degradation rate of ORZ (0.066 min −1 ) on the optimally Ag-doped MoS 2 was about 41 times higher than that of the sole PMS system and 5.5 times higher than that of bare MoS 2 . Furthermore, this catalyst enabled the efficient removal of various dye and antibiotic contaminants, including carbamazepine (CBZ), methylene blue (MB), and tetracycline (TC). Meanwhile, PVDF composite catalytic membranes were successfully fabricated in this study, which solved the critical problem of difficult recovery and reusability of powder catalysts. This new strategy can significantly enhance piezo-promoted PMS activation, providing important insights for the removal of pollutants.

Charge separation, transfer, and recombination are crucial factors that influence the efficiency of photocatalytic Cr(VI) reduction. The construction of Schottky junctions can remarkably facilitate the spatial separation of charge carriers. To address the issue of heavy metal pollution in industrial wastewater, an Ag-DUT-67 Schottky junction photocatalyst was synthesized by depositing silver nanoparticles (Ag NPs) onto the DUT-67 surface through a photoreduction technique. The findings indicate that Ag NPs are evenly distributed and coordinated with the sulfur atoms in the DUT-67 ligands. This modification not only elevates the oxygen vacancy content but also broadens the light response range. A Schottky barrier is established at the Ag-DUT-67 interface, which effectively reduces carrier recombination. Notably, Ag-DUT-67–2 demonstrates a remarkable Cr(VI) reduction efficiency of 98% within 30 min, with a reaction rate that is 3.4 times as much as pristine DUT-67. Additionally, Ag-DUT-67–2 shows excellent stability in high-concentration Cr(VI) solutions and in the presence of interfering ions, coupled with good recyclability. This study offers a novel framework of interface engineering and performance enhancement of MOF-based photocatalysts for heavy metal reduction.

Organic polymer materials are promising for energy storage owing to their high safety and structural tunability. However, their practical application is hindered by poor cycling stability, low electrical conductivity, and high solubility. This study utilized the silver nitrate (AgNO 3 ) displacement reaction to innovatively in situ construct a sandwich-structured organic electrode with nanomesh metal-based SEI film. It effectively addressed the limitations of the two interface layers of active material/electrolyte and active material/collector to achieve interfacial stabilization and fast ion transport. The three-dimensional mesh metal-based artificial SEI layer with attached nanoparticles not only effectively inhibits the electrode material from being attacked by the electrolyte and reduces the solubility of organic materials, but also the attached nanoparticles can enhance the conductivity of the material. In addition, the pure Ag metal layer between the active material and the Cu foil collector can effectively improve the electrical conductivity and accelerate the electron transfer, which plays a key role in keeping the internal resistance stability of the battery. The composite electrode material exhibits excellent rate performance and stable long cycling performance at a high rate (46.1 mAh g −1 after 2000 cycles at 20 C, 1 C = 223 mAh g −1 ). Furthermore, Density functional theory (DFT) calculations and theoretical analysis provided detailed explanations of the energy storage pathways and utilized the electronic structure to reveal the synergistic effect mechanism existing among the sandwich structures. Therefore, providing a new strategy for designing organic polymer materials to be used in high-performance energy storage devices in the future.

The toxicity of silver ion (Ag + ) poses a serious threat to the environment and food safety, therefore, the accurate, economical and efficient monitoring of Ag + is crucial for protecting human health and environment. However, constructing an efficient, versatile platform that enables precise sensing of heavy metal ions remains challenging. Here, carbon dots (TN-CDs) were fabricated and optimized using p-phenylenediamine and p-toluenesulfonyl azide as precursors, with orange emission of 606 nm and quantum yield of 9.96%. The TN-CDs achieved highly sensitive, and selective detection of Ag + based on the static quenching effect, with a limit of detection (LOD) at 9.3 nM. Further, the TN-CDs extended test paper inherited the excellent sensing performance unequivocally and exhibited superior stability and accuracy with long-term storage. Thus, a smartphone-assisted strategy was developed and enabled rapid, portable Ag + detection with a convenient visual readout, accomplishing the LOD at 75.79 nM. Notably, the tests in real water samples, soil, and food samples attained excellent recoveries within 95.10–105.76%, confirming their excellent environmental tolerance and potential applicable capability. This work provided an efficient synthetic strategy for N-doped CDs with sensing capability, emphasizing their potential for application in food safety, healthcare, and environmental conservation.

In this study, an Ag/CuV 2 O 6 composite was constructed by loading Ag NPs onto CuV 2 O 6 nanowires through a sodium borohydride reduction method. The introduction of Ag NPs significantly enhanced the photocatalytic antibacterial effect of CuV 2 O 6 . Specifically, the material exhibited the optimal photocatalytic antibacterial performance when the Ag loading was 3%. During the antibacterial process, as the illuminated time increases, the membrane structure of bacteria is gradually impaired, and intracellular contents including K + , RNA, and proteins are gradually leaked out, ultimately resulting in bacterial inactivation. EPR and free radical scavenging experiments have confirmed that reactive oxygen species (ROS), including singlet oxygen ( 1 O 2 ) and superoxide anion radicals (·O 2 - ), generated via photocatalysis, are the main factors in killing bacteria. As an excellent electron transporter, Ag effectively promotes the separation of electron-hole pairs in CuV 2 O 6 , enhances the generation efficiency of ROS, and thereby improves the photocatalytic antibacterial activity. To address the limitation of photocatalysis requiring continuous light irradiation, the long-afterglow fluorescent material ZnGa 2 O 4 :0.5%Tb 3+ was further introduced. Under intermittent light irradiation, the material stores energy upon excitation by the light source. After the light irradiation is terminated, it continues to activate the Ag/CuV 2 O 6 composite, allowing the generation of ROS even in the dark and thus achieving a delayed antibacterial effect. This study provides a new strategy to reduce the dependence of photocatalytic antibacterial technology on continuous light sources.

The catalytic conversion of lignin derivatives into specific chemicals represents a key pathway for achieving high-valued utilization of biomass. A new Ag–Co 0 /Fe 0.04 Co 0.96 O catalyst was constructed for the selective demethoxylation of vanillic acid derived from lignin depolymerization to produce p-Hydroxybenzoic acid. Compared to Ag–Co 0 /CoO, Fe doping suppressed Co reduction, endowing the Ag–Co 0 /Fe 0.04 Co 0.96 O catalyst with suitable hydrogenation activity and more abundant acidic sites. The hydrogen spillover effect inhibited decarboxylation, dehydroxylation, and benzene ring hydrogenation during the demethoxylation reaction. Oxyphilic Fe species changed the adsorption geometry of vanillic acid from parallel adsorption into twist configuration, avoiding the hydrogenation of benzene ring, and thereby improving the demethoxylation selectivity to p-Hydroxybenzoic acid. By optimizing catalyst preparation and reaction conditions to minimize decarboxylation and over-hydrogenation byproducts, the Ag–Co 0 /Fe 0.04 Co 0.96 O catalyst contributed to a 98.52% conversion of vanillic acid and a 89.62% selectivity to p-Hydroxybenzoic acid under 0.4 MPa H 2 , 0.4 MPa CO 2 at 220 °C for 2 h. This research provided a theoretical foundation and practical guidance for the catalytic demethoxylation of phenolic acids, offering new insights into high-valued utilization pathways for biomass.

In recent years, food safety concerns associated with veterinary drug residues have aroused significant public attention, highlighting the critical need for continuous monitoring in both animal-derived foods and the environment to safeguard public health. Medroxyprogesterone acetate (MPA), a major anabolic steroid widely used in animal husbandry, poses potential human health risks according to recent studies. Although conventional analytical techniques based on chromatography and immunological assays are effective, they often suffer from complex operations, the need for skilled personnel, high cost, and time consumption. To overcome these limitations, electrochemical immunosensors modified with advanced nanomaterials offer a promising alternative. Herein, a highly sensitive electrochemical immunosensor was developed for trace MPA detection utilizing core–shell SiO2-PEI@Ag nanoparticles as the sensing matrix. In this nanocomposite, the structural synergy between the SiO2core and outer Ag NPs shell not only provides a high-density platform for specific antibody immobilization, but also drastically expands the electroactive surface area and accelerates electron transfer to maximize signal amplification. Benefiting from these synergistic advantages, the constructed immunosensor exhibited a limit of detection (LOD) of 0.014 ng/mL and a wide linear range of 0.03–100 ng/mL. Furthermore, the recovery rates in pork and milk samples were 91.32–97.29% and 95.14–102.54%, respectively. In addition, negligible cross-reaction was observed toward structurally related steroid hormones related to MPA and common antibiotics. The immunosensor shows good stability, reproducibility, and accuracy, demonstrating great potential as a promising candidate to complement conventional tools for future MPA residue screening.

The persistent accumulation of tetracycline (TC) antibiotics in aquatic environments poses severe ecological and public health risks, necessitating the development of multifunctional platforms capable of simultaneous detection and degradation. Herein, we report magnetically recoverable plasmonic Fe3O4/Cu2O-Ag nanocomposites (NCs) that integrate visible-light-driven photocatalysis with ultrasensitive surface-enhanced Raman scattering (SERS) detection. Hierarchical flower-like Fe3O4nanocrystals were employed as magnetic supports, followed by in situ growth of Cu2O nanocrystals and controlled deposition of Ag nanocrystals. The optimized composite (FCA-2) exhibited enhanced visible-light absorption (Eg= 1.86 eV), suppressed electron–hole recombination, and improved photocurrent response, which were attributed to Schottky barrier formation at the Cu2O-Ag interface and localized surface plasmon resonance (LSPR) effects. Under simulated solar irradiation, FCA-2 NCs achieved 91.79% degradation of TC within 60 min, following pseudo-first-order kinetics (k = 20.37 × 10−3min−1). Finite-difference time-domain (FDTD) simulations revealed that optimal Ag loading maximized plasmonic “hot spot” density, thereby enhancing electromagnetic field intensity and SERS performance. The FCA-2 substrate enabled ultrasensitive TC detection with a limit of detection of as low as 10−10M. Moreover, the superparamagnetic Fe3O4core allowed for rapid magnetic separation and sustained performance over multiple SERS–photocatalysis cycles, with negligible signal attenuation after 30 days. This work presents a rational strategy for constructing plasmonic magnetic NCs that synergistically couple photocatalytic remediation, ultrasensitive sensing, and magnetic recyclability, offering significant potential for integrated environmental monitoring and sustainable water treatment applications.
