Eliminating various organic pollutants from wastewater continues to pose a major environmental issue. Herein, CO 2 -responsive magnetic bio-aerogels (Ag/Fe-NC@DCG) integrating “smart” adsorption and photo-Fenton-like degradation were constructed by embedding surface plasmon resonance (SPR)-enhanced MOF-derived Ag/Fe nanocarbon (Ag/Fe-NC) into cellulose nanocrystal reinforced gelatin aerogels, followed by surface functionalization with a CO₂-responsive silane coupling agent ( N, N -diethyl-3-aminopropyltrimethoxysilane). The resulting aerogels exhibited outstanding adsorption capacities toward charged pollutants, reaching 859.62 mg/g for negatively charged methyl orange (MO) and 635.92 mg/g for positively charged methylene blue (MEB), governed by electrostatic interactions and hydrogen bonding. The adsorption process was well described by the Langmuir adsorption isotherm model and pseudo-second-order adsorption kinetic model. Remarkably, CO 2 served as a trigger gas to enable rapid and selective adsorption of negatively charged organic pollutants from the mixture, thereby realizing CO 2 -regulated selective adsorption. As anticipated, under visible light irradiation in the presence of peroxymonosulfate (PMS), the Ag/Fe-NC component efficiently catalyzed photo-Fenton-like reactions, leading to significantly enhancing removal efficiencies for both charged and neutral organic pollutants. For neutral bisphenol A (BPA) and amphoteric tetracycline hydrochloride (TCH) that were initially unadsorbed, their removal efficiencies rose dramatically from 5.24% and 12.79% to 90.67% and 97.40%, respectively. Additionally, the aerogels demonstrated excellent recyclability, mechanical robustness, and antibacterial activity. Overall, this work presents a versatile and sustainable aerogel platform that integrates CO 2 -triggered selective adsorption with photo-Fenton-like degradation, offering a prospective pathway for wastewater remediation.

Achieving high-performance flexible electronics requires material systems capable of unifying mechanical resilience with multifunctional properties such as electrical conductivity and thermal management. In this study, a monolithic, self-supporting composite membrane with an interpenetrating network of MXene, aramid nanofiber (ANF), and Ag nanoparticles was successfully fabricated via a one-step process that integrates vacuum-assisted filtration with in situ redox assembly. In this integrated architecture, ANFs form a robust mechanical scaffold. MXene nanosheets establish a foundational conductive network. Critically, the in situ formed AgNPs act as conductive bridges, electrically interconnecting the MXene sheets to significantly enhance the overall electrical conductivity. The sequential addition protocol, finalized with extra MXene, optimizes this ternary network by enhancing dispersion and interfacial compatibility, yielding a stable, synergistic structure. Benefiting from multilevel interfacial synergy, the resulting 40 μm-thick monolithic membrane integrates multiple high-performance functions, an EMI shielding effectiveness of 48 dB, rapid Joule heating up to 210 °C within 20 s at a low voltage of 1.5 V, and notable electrochemical activity. When used as a freestanding electrode for zinc-ion storage, it delivers an areal capacity of 1.7 mAh cm–2 with remarkable rate capability. This work establishes a scalable, integrated fabrication strategy, offering a robust platform for next-generation applications in wearable electronics, thermal management, and microenergy systems.

In this study, a silver-based metal–organic framework (Ag-MOF) nanozyme was synthesized for the synergistic eradication of drug-resistantSalmonellaenteritidisin food matrices. Ag-MOF exhibits multiple enzyme-like activities, namely oxidase (OXD)-, peroxidase (POD)-, and superoxide dismutase (SOD)-like activities. It demonstrated excellent antibacterial and antibiofilm activities against erythromycin- and chloramphenicol-resistantS. enteritidisstrains (N29 and P23). Specifically, treatment with 20 mg mL−1Ag-MOF resulted in nearly complete eradication ofS. enteritidisin in vitro suspension assays, including 1 × 107CFU mL−1N29 strain and 6 × 106CFU mL−1P23 strain. Moreover, treatment with 1 mg mL−1Ag-MOF led to 80~90% biofilm inhibition ofS. enteritidis. Mechanistic investigations revealed that Ag-MOF effectively interacted with amino-rich structures on the bacterial surface (such as membrane proteins and peptidoglycan components), generated abundant reactive oxygen species (ROS), released Ag+ions, and depleted intracellular glutathione, which collectively disrupted cell membrane integrity and induced severe leakage of intracellular proteins and nucleic acids. Importantly, Ag-MOF maintained high antibacterial efficacy in complex simulated food matrices (pork, milk, and egg shell). Overall, this study offers key insights into enzyme-mimicking antibacterial materials and a promising strategy to combat multidrug resistant foodborne pathogens.

Exploring stable and efficient photocatalysts to promote the photo-oxidative degradation of volatile organic compounds (VOCs) is essential for air pollution control. In this study, MIL-101(Fe) modified with silver nanoparticles (Ag NPs) was synthesized via a simple solvothermal method. Under visible light irradiation for 90 min, the optimal catalyst MF/Ag-5% composite achieved a styrene conversion rate of 91.8%, with a corresponding kinetic rate constant of 0.022 min⁻ 1 . Moreover, the catalyst retained its photocatalytic activity over four consecutive cycles. The results indicate that the incorporated Ag NPs effectively extract photogenerated electrons from MIL-101(Fe), thereby promoting efficient charge carrier separation. Additionally, the localized surface plasmon resonance (SPR) effect of Ag NPs extends the light absorption range of MIL-101(Fe), facilitating the generation of reactive species such as hydroxyl radicals (·OH) and superoxide anion radicals (·O₂⁻). This work offers a novel approach for designing highly efficient and stable photocatalysts for air purification applications.

Aspiration pneumonia (AP), caused by the microinhalation of gastric contents, is easy to miss because of its nonspecific symptoms and is associated with a high mortality rate (46.1%) over a short disease course. Current diagnostic methods for aspiration pneumonia, including medical imaging and bronchoscopy, are difficult to use for onsite and rapid diagnosis because they require bulky and time-consuming equipment. In this work, we propose an ultrasensitive electrochemical immunosensor to achieve fast determination of the AP biomarker (pepsin) in the bronchoalveolar lavage fluid (BALF) of AP patients. This immunosensor works through the construction of heterogeneous Ag@Co(OH)2 NWs to simultaneously provide both high electrocatalysis and high conductivity. In terms of architecture, Ag NWs can contribute abundant active sites for antibody immobilization to achieve target capture ability while accelerating electron transfer. In addition, the uniformly distributed Co(OH)2 nanoparticles intensify the response signal because of their high redox capacity. Through the above synergetic effects, our immunosensor enables the recognition and reporting of trace amounts of pepsin in patients’ BALF within only 20 min, which is at least two times faster than that of clinical techniques. Moreover, the high diagnostic accuracy of the immunosensor is comparable to that of CT images from clinical AP patients. This facile immunosensor is promising for providing new insights into the early diagnosis of AP to guide clinical treatment onsite.

The residue of chloramphenicol (CAP) in animal-derived foods and the environment poses a serious threat to human health, highlighting the urgent need for sensitive, selective, and rapid detection methods. In this study, a novel electrochemiluminescence resonance energy transfer (ECL-RET)-based sensing platform was developed for the ultrasensitive detection of CAP, employing a Tb-PTC/Ag MOF composite as the energy donor and hollow ZIF-8@polydopamine (ZIF-8@PDA) as the energy acceptor. Coordination of Tb 3+ with PTCA ligands within the MOF framework effectively suppressed aggregation-induced quenching, while the incorporation of Ag MOF further enhanced and stabilized the ECL intensity through synergistic effects. Efficient ECL-RET was achieved owing to the spectral overlap between the UV-vis absorption of the acceptor and the ECL emission of the donor, with a high energy transfer efficiency of 75.1%, significantly improving the sensitivity of the sensor. The proposed platform exhibited a wide linear range from 10 −5 to 10 −15 mol L −1 for CAP detection, with an exceptionally low detection limit of 1.57 × 10 −15 mol L −1 . By integrating the structural advantages of MOFs with the high sensitivity of the ECL-RET strategy, this work establishes a robust and promising platform for trace-level CAP monitoring in environmental and food samples.

The light collection ability, surface oxidation reaction kinetics, bulk charge carrier separation efficiency, and surface charge injection efficiency play a crucial role in hydrogen production through solar-driven water splitting of semiconductor photoanodes in photoelectrochemical (PEC) system. Surface plasmon resonance (SPR) effect of plasmonic metals exhibits a potential to simultaneously boost the aforementioned performances of semiconductor photoanodes. Herein, the SPR effect of plasmonic Ag nanoparticles is exploited to augment PEC performance of BiVO 4 photoanode. The modification and SPR effect of Ag nanoparticles not only substantially accelerates the reaction kinetics of surface water oxidation but also enhances surface charge injection and bulk charge separation efficiencies of BiVO 4 nanostructure photoanode, leading to 361% enhancement in injection efficiency of surface charges and 126% enhancement in separation efficiency of bulk charges compared with those of pristine BiVO 4 photoanode. As a result, the optimized BiVO 4 /Ag nanostructure photoanode exhibits significantly enhanced PEC performance in Na 2 SO 4 electrolyte without sacrificial agent, and achieves a photocurrent density of 2.3 mA cm −2 at 1.23 V vs. reversible hydrogen electrode, 5 times of unmodified BiVO 4 nanostructure photoanode. This wok offers valuable insights into boosting PEC performance of wide bandgap semiconductor photoanodes through utilizing SPR effect of metals to simultaneously improve surface oxidation reaction kinetics, bulk charge separation and surface charge injection.

Ag nanoparticles and nanostructured surfaces have been widely used as surface-enhanced Raman scattering (SERS) substrates, which can enhance the Raman signals when molecules are adsorbed on the surface of Ag by the effect of Ag-thiol bonds. In this paper, we propose an efficient method to remove the molecules adsorbed on Ag with sodium borohydride solution, providing a protocol to realize a reproducible and practicable Ag SERS substrate. A theoretical density function theory approach has been used to explain the mechanism of desorption.

Asymmetric electrode reactivity confines viologen redox to ITO interface. • Ag/TiO₂ conduction band edge prevents electron transfer to viologen. • Voltage polarity reversal achieves electrochemically controlled bleaching. • Textile-based planar device design suits wearable electrochromic applications. This study addresses the key challenge of slow bleaching kinetics in conventional viologen-based electrochromic devices (ECDs) employing solid/gel electrolytes by proposing a novel electrode engineering strategy based on differentiated electrode reactivity. The Ag/TiO₂ fabric electrode, due to the semiconducting properties of its TiO₂ coating, exhibits insufficient reducing power to drive the reduction and coloration of dissolved viologen cations. Leveraging this principle, an asymmetric planar ECD with reaction "directionality" was constructed, consisting of an ITO electrode paired with an Ag/TiO₂ fabric electrode in a side-by-side configuration. In this design, the viologen coloration/bleaching reactions are effectively "confined" to the ITO electrode interface. Simply switching the polarity of the applied voltage (±1.0 V) enables controllable coloration (7.4 s) and active bleaching (16.5 s), which is over 98% faster than the natural diffusion-driven bleaching observed under open-circuit conditions (>900 s). Unlike conventional approaches that require complementary electroactive layers or immobilized redox species, this strategy circumvents the slow spontaneous back-reaction solely through electrode-level thermodynamic control. Furthermore, by patterning the ITO electrode, its potential for applications in flexible displays was demonstrated. This work provides a novel and effective electrode engineering strategy for developing high-performance, rapidly switchable, and designable wearable electrochromic devices.

The performances of photovoltaic devices can be improved by increasing light-harvesting and charge collection respectively. The design and synthesis of nanocomposites with the ability of enhancing the generation and collection of the photo-generated electrons provide a significant way to improve the power conversion efficiency (PCE). Herein, SWNTs@(TiO2/Ag/Au) nanocomposites were synthesized and successfully integrated into photoanode films of dye-sensitized solar cells (DSSCs) to improve the power conversion efficiency. The synthesis processes were based on multi-functional DNA. DNA not only works as a dispersing agent preventing SWNTs bundling but also as a sacrificial mold assembling TiO2, Ag and Au nanoparticles on the surface of the SWNTs. The synthesized SWNTs@(TiO2/Ag/Au) nanocomposites enhance the charge collection and light-harvesting of DSSCs simultaneously. With 2.45 wt% SWNTs@(TiO2/Ag/Au) nanocomposites incorporating into the photoanode films, the PCE of the DSSCs increases from 6.8% to 8.3%.

Photocatalyst Ag/ZnO-TiO 2 was prepared by template method. The catalyst was characterized by XRD, SEM, and UV-vis DRS. Rhodamine B (RhB) and target pollutants were used to evaluate the photocatalytic performance of the catalyst under 40 W UV-lamp. The photocatalytic degradation mechanism of Rhodamine B was discussed through free radical quenching experiment. The experimental results show that hexagonal ZnO-TiO 2 can be successfully prepared by template method, and nano Ag particles are evenly loaded on the catalyst. Under the reaction conditions of 1% catalyst input and 40 W UV-lamp, the catalytic degradation rate of RhB by Ag/ZnO-TiO 2 was 98.28%. The photocatalytic degradation mechanism of Ag/ZnO-TiO 2 was explored by free radical quenching experiment. The experimental results show that H + and ·OH play a major role in the photocatalytic degradation of RhB by Ag/ZnO-TiO 2 .

Electrochemical CO 2 reduction reaction (CO 2 RR) towards CO is considered as one of the most promising routes to alleviate carbon emissions and achieve a carbon-neutral cycle. In this work, a highly dispersed Ag-BTC catalyst (BTC refers to the 1,3,5-benzenetricarboxylate ligand) with abundant catalytically active sites has been synthesized via a facile one-step hydrothermal method. Efficient, highly selective, and stable electrochemical reduction of CO 2 into CO has been achieved on the Ag-BTC electrocatalyst. The faradaic efficiency of CO production from the CO 2 RR is around 95%, which is within the range of highest values reported to date. A correlation between the structure of the Ag-BTC electrode and its enhanced catalytic performance has been established through the combination of characterization results and electrochemical measurements. Furthermore, a lower Gibbs free energy change (∆G) for the rate-determining step regarding the formation of intermediate COOH ads also leads to the superior catalytic performance of CO 2 RR on Ag-BTC.
