While aqueous zinc-ion batteries (AZIBs) show great promise for safe energy storage, their practical implementation is impeded by performance issues at the Zn anode, such as parasitic side reactions, hydrogen evolution, and dendritic growth. Here, we report a fluorine-doped carbon nanofiber (FCNF) 3D coating that provides dynamic, durable protection for the zinc anode. The coating's 3D architecture, intrinsic negative charge, and hydrophobicity synergistically guide uniform zinc deposition while inhibiting parasitic reactions. More importantly, a ‘sustained supply and dynamic formation’ mechanism is realized, where C F bonds within the FCNF dynamically cleave during cycling to enable the continuous in-situ formation of a ZnF 2 layer that persistently suppresses side reactions. Consequently, symmetric cells employing FCNF-protected anodes demonstrate an operational lifetime exceeding 3400 h at a high areal capacity of 2.5 mAh cm −2 . Moreover, when assembled with an ammonium vanadate cathode, the full cell stably cycles for over 1000 cycles at 5 A g −1 , maintaining 82% of its initial capacity. This work introduces an approach that synergistically combines physical guidance and dynamic chemical repair, offering a robust solution for developing highly stable and safe metal batteries with aqueous electrolytes.

Efficient and sustainable Fenton-like systems are highly desired for degrading persistent pollutants. However, their development is often hindered by the slow redox kinetics and poor durability of single active sites in conventional metal-based catalysts. Herein, we developed a bimetallic Fe/Cu catalyst (FeCu-BN) with highly dispersed metal sites anchored on boron nitride (BN), which offered boosted activity and stability via the cooperative redox cycles between Fe and Cu sites. The FeCu-BN catalyst achieved nearly 100% removal of sulfamethoxazole (SMX) within 20 min through activating peroxymonosulfate (PMS), with a rate constant of 0.421 min − 1 significantly surpassing those of its monometallic counterparts and other advanced catalysts. Systematic experiments and theoretical calculations revealed that the Cu sites not only optimized the electronic structure of the Fe sites but also provided electrons extracted from pollutants to promote the Fe 2+ /Fe 3+ cycle, thereby triggering concerted radical and non-radical reactions for SMX elimination. Consequently, the FeCu-BN/PMS catalytic system operated stably over a wide pH range and exhibited exceptional tolerance to various inorganic ions and complex aqueous matrices. Furthermore, in a continuous flow membrane reactor, the system maintained efficient SMX removal over 20 h without significant performance loss. This work uncovered the synergistic redox cycling mechanism in bimetallic catalysts and offered valuable insights for designing dual-site catalysts for environmental remediation.

The design and preparation of adsorbents are crucial in the field of wastewater treatment. The composite adsorbents with chitosan (CTS) and metal organic framework (MOF) were fabricated to enhance the diffusion degree of MOF and acid stability of CTS by heating reflux method and effect of ratio of CTS, Cu 2+ and 2-aminoterephthalic acid of the composite adsorbents on adsorption was investigated. The diffusion degree of MOF on the composite adsorbent (CTS-MOF) was enhanced on the basis of FESEM images. The acid instability of CTS on the CTS-MOF was improved as CTS can partly dissolve in solution with pH lower than 4.0, while the composite was stable. The composite material was used to remove anionic dye methyl orange (MO) from contaminated aquatic environments. The adsorption kinetics showed that the adsorption capacities of CTS-MOF, CTS and MOF for MO with concentration of 200 mg/L were 135.49, 34.84 and 58.95 mg/g, respectively, and the adsorption capacity of CTS-MOF increased to 3.89 and 2.30 times, accordingly, compared to that of CTS and the MOF, due to synergetic effect of CTS and MOF. The adsorption process of CTS-MOF followed pseudo-second-order kinetic model and Langmuir model. In addition, the adsorption was endothermic. For CTS-MOF, the solution pH exhibited slightly small fluctuation on MO adsorption. The presence of NaCl exhibited positive effect for MO adsorption onto the MOF while negative effect for MO onto CTS-MOF, and the influence on the CTS-MOF was much less than that onto the MOF, indicating the salt tolerance of CTS-MOF was better. Adsorption mechanism was analyzed by the FTIR spectra before and after adsorption and quantum chemical calculation by means of independent gradient model based on Hirshfeld partition (IGMH) analysis. And IGMH analysis showed the relative magnitude of coordination effect, hydrogen bonding and π-π stacking involved in the adsorption process. This study provided a valuable method to design and prepare adsorbents with high adsorption efficiencies for organic dyes from aqueous solution.

Avionics equipment often use epoxy resin as encapsulation material. However, epoxy resins have limited performance in terms of heat dissipation, electromagnetic shielding, and resistance to moisture and heat. As the integration of avionics continues to increase, epoxy resins have become more and more difficult to meet the stringent requirements for high reliability of avionics in the aerospace industry. In this study, inspired by the unique structure of lotus leaves, a thin film composite of mesophase carbon microspheres (MCMB) and manganese dioxide (MnO 2 ) was prepared on the surface of a copper foil using a mechanical hybrid spraying method. The film exhibits excellent superhydrophobicity with a water contact angle of 161.1°. This performance was attributed to its micro- and nanoscale roughness structure and low surface energy modification by POTS/stearic acid. In terms of infrared stealth, the composite material effectively suppresses thermal radiation through a trapped air layer and gradient thermal resistance design. In addition, the material’s electromagnetic shielding effectiveness in the 2.4 GHz band reaches −56 dB, originating from the synergistic effect of reflection loss in the copper substrate and dielectric absorption in MnO 2 . At the same time, the three-dimensional network constructed by the MCMBs gives the material high thermal conductivity, which significantly improves the thermal management efficiency. The composite film also has good abrasion resistance, chemical stability and self-cleaning function, which is suitable for avionics and other fields of protection, providing a new solution to solve the problem of avionics packaging.

The sulfidation of zero-valent iron (S-ZVI) has emerged as an effective strategy to enhance reactivity for contaminants removal, yet the underlying mechanisms remain incompletely understood. This study explores the enhanced reactivity of S-ZVI derived from five different commercial sources in the aerobic removal of four representative azo dyes. Sulfidation converts the passive Fe-oxide film into a conductive FeS x layer, thereby facilitating interfacial electron transfer from the Fe 0 core to adsorbed dye molecules, and promoting sustained Fe(II) regeneration for decolorization of azo dyes. It demonstrates that the rate constants of S-ZVI for azo dyes removal exhibited 1.1–2.3 fold higher than unsulfidated ZVI, with strong linear correlations across dyes and sources (R = 0.69–0.98), suggesting predictable reactivity scaling. Correlation analysis, spectroscopic evidences and chelation–quenching tests jointly confirm that low charge-transfer resistance and sustained Fe(II) release govern the enhanced reductive reactivity, whereas radical-mediated oxidation contributes only as a secondary pathway. Consequently, S-ZVI exhibited efficient azo-bond cleavage, partial mineralization, and retained over 80% of its reactivity toward azo dye after six reuse cycles under aerobic conditions. Overall, this work establishes quantitative structure–reactivity relationships linking sulfur speciation, interfacial electrochemical properties, Fe(II) dynamics, and degradation kinetics, providing a predictive framework for designing durable and high-performance ZVI-based materials for wastewater treatment.

The environmental pollution resulting from organic dye wastewater presents a significant threat to human health. Photocatalysis has emerged as a highly promising approach for mitigating wastewater contamination. In this study, a novel synthetic strategy was developed using NH 2 -UiO-66 as a template. By precisely controlling the amount of Ag + ions introduced into the NH 2 -UiO-66 precursor and employing a straightforward reduction approach, the Ag-NH 2 -UiO-66 composite photocatalyst was successfully synthesized. Comprehensive characterization via X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), transmission electron microscopy (TEM), and X-ray photoelectron microscopy (XPS) confirmed that the incorporated Ag+ ions were effectively reduced to metallic silver and uniformly dispersed within the porous framework. Photocatalytic degradation experiments employing Rhodamine B (RhB) as a model pollutant under ultraviolet irradiation demonstrated that the catalyst with a silver loading of 0.05 mol/L achieved a maximum degradation efficiency of 91% within 150 min, markedly surpassing the 39% efficiency exhibited by pristine NH 2 -UiO-66. Furthermore, cyclic stability tests verified the catalyst's excellent reusability and structural durability. Mechanistic investigations revealed that superoxide radicals (O 2 − ) served as the predominant reactive species responsible for RhB degradation in the Ag-NH 2 -UiO-66 system. This work presents a simple and effective strategy for fabricating highly efficient and stable MOF-based photocatalysts for the remediation of dye-contaminated wastewater.

Herein, a novel ratiometric fluorescent nanosensor was prepared by in-situ incorporation of Eu 3+ into nitrogen-rich carbon dots (Eu-CDs) via a one-step hydrothermal route. The obtained Eu-CDs display dual emission: a strong blue band at 440 nm (carbon core) and a weak red band at 615 nm ( 5 D 0 → 7 F 2 transition of Eu 3+ ). Upon titrating oxytetracycline (OTC) into the system, the blue signal remained invariant as an internal reference, whereas the red emission dramatically enhanced by the OTC-mediated antenna effect. The intensity ratio ( I 615 / I 440 ) increases linearly with OTC concentration over 1.0 – 50 µM, affording a limit of detection of 35 nM. Concomitantly, the dispersion exhibits a naked-eye color switch from blue to red under 365 nm UV illumination. Mechanistic investigations reveal that the specific recognition originates from (i) coordination between Eu 3+ and the β-diketone moiety of OTC and (ii) hydrogen-bonding interactions between OTC and the CDs surface. Although the probe is highly selective toward OTC over common ions and amino acids, it suffers from cross-reactivity among tetracycline antibiotics. This limitation was overcome by coupling the ratiometric read-out with linear discriminant analysis (LDA) of dual-mode (fluorescence and absorption) data, enabling 100% correct classification of OTC, tetracycline (TC), chlortetracycline (CTC), and doxycycline (DC) in both individual and mixed samples. The proposed strategy furnishes a simple, green and low-cost route to Eu-CDs and establishes a robust, portable platform for ultrasensitive quantification and discriminative sensing of tetracycline antibiotics in complex matrices.

Tribocatalysis is an emerging methodology for water purification by harnessing frictional energy. BaTiO3 has shown promising activity in the tribocatalytic degradation of organic pollutants; however, further performance improvement through structural and surface engineering remain challenge. Herein, a facile wet chemistry method was employed to modify the surface of commercial BaTiO3 by depositing TiOx colloids, which enhanced the reaction rate from 0.080 h-1 for pristine BaTiO3 to 0.272 h-1 for BaTiO3 modify by TiOx colloids. The catalysts were characterized by XRD, TEM, XPS, and Raman and the results indicated that the modified BaTiO3 consisted of a BaTiO3 core encapsulated by an ultrathin TiOx shell with an increased concentration of oxygen vacancies. UV-vis, PL spectra, EIS, and DFT calculations demonstrated that the TiOx modification effectively narrows the band gap energy and promotes the separation of electron-hole pairs during tribocatalysis, thereby facilitating the production of more reactive species. Combining EPR analysis and quenching tests, tribogenerated holes were identified as the predominant reactive species surpassing the contributions of •O2- and •OH. This study highlights the efficacy of the wet chemistry approach for the rational design of advanced tribocatalysts, offering new insights into optimizing catalytic materials for the degradation of organic contaminants.

Membrane-based separation of nonpolar solvents is critically important for petroleum refining, chemical production, and food processing industries. Although membrane technology provides energy-saving advantages, conventional organic nanofiltration membranes suffer from inadequate separation performance in nonpolar systems, hindering their practical deployment. Covalent organic frameworks (COFs) emerge as an ideal platform for this application due to their unique combination of chemical robustness, high porosity, and precisely adjustable pore structures. In this work, we present an innovative strategy that integrates trifluoromethyl-functionalized COFs with surfactant-assisted interfacial polymerization to achieve high-flux nonpolar organic solvent nanofiltration. The resulting COF membranes demonstrate remarkable separation capabilities, achieving an ultrahigh hexane permeance of 251.4 L m −2 h −1 bar −1 and a remarkable 96.2% rejection for lecithin in hexane solutions, surpassing all previously reported OSN membranes. This innovative strategy not only addresses current limitations in nonpolar solvent separation but also establishes a new paradigm for developing high-performance separation membranes, with significant potential for industrial applications.

Given the limited performance of traditional biochar adsorbents, this study proposes an innovative two-step pyrolysis strategy for the precise synthesis of N F double-site co-doped biochars (NFBCs). This strategy effectively regulates the pore structure and surface chemistry of the material. The optimized material (NFBCs-1:3) exhibited an ultra-high specific surface area (2187 m 2 /g) and abundant active sites. Its maximum adsorption capacity for norfloxacin (NOR) reached 552.65 mg/g, significantly exceeding that of traditional biochar and most reported materials. The adsorption process followed pseudo-second-order kinetics and the Sips model. Mechanistic studies showed that its excellent performance stems from the synergistic effects of pore filling, π-π interactions, hydrogen bonding, and electrostatic interactions, with the unique N F double-site regulation of the electronic structure as the key. In addition, NFBCs-1:3 maintained excellent adsorption performance across a wide pH range, under coexisting ion interference, and in a variety of real-world water matrices, confirming its great application potential in the treatment of complex real-world wastewater. This study provides a new idea for the design of efficient and stable non-metal-doped carbon-based adsorbents.

The efficient degradation of organic pollutants remains a significant challenge in the field of catalysis, and the recycling of granular catalysts remains a persistent challenge during repeated usage. Herein, a ZnO@PVDF(Polyvinylidene Fluoride)-Nanopillar membrane has been prepared by combing the template and hydrothermal method and was applied in degrading methyl orange(MO) dye. The catalytic degradation rate attained 98.05 % at 360 min under the condition of ultrasonication and ultraviolet light being attributed to the composition and the bionic pine branch structure under a synergistic mechano(contactelectric & piezoelectric)-photocatalytic tri-catalysis. The PVDF-Nanopillar substrate as a dielectric material served as the reservoir of electron hole pair and prolonged their recombination by engineering a PVDF/ZnO nanorod heterojunction. Furthermore, the robust and reusability of this composite membrane were detected and the results indicated the membrane could also catalyze the degradation of dexamethasone, and its morphology and composition changed little comparing that in the recycling experiment after with before. Remarkably, the designed ZnO@PVDF-nanopillar membrane achieves ≈ 100 % organic pollutant degradation efficiency and enables facile catalyst recovery, offering a practical solution for sustainable water treatment applications, improving the catalytic convenience. This work provides new design principles for constructing organic-inorganic heterojunctions in environmental catalysis, offering fresh insights into hybrid material engineering.

Integrating derivatives of Cu-organic frameworks (CuBTC) into robust macroscopic architectures while preserving their intrinsic porosity and multifunctionality is crucial for advancing their practical application in environmental technologies. Herein, a multifunctional CuBTC-derivatives aerogel is engineered via a facile sol–gel process followed by vacuum drying for high-performance water purification. The resulting monolithic aerogel exhibits a hierarchically porous three-dimensional network with exceptional structural integrity and stability. This architecture demonstrates outstanding solar-thermal conversion capabilities, enabling highly efficient solar-driven interfacial desalination with an elevated evaporation rate and remarkable energy efficiency. Under 1 sun, the CuBTC-350-aerogel evaporator achieved water evaporation rate of 2.06 kg m⁻²h⁻¹ and efficiency of 91.5 % for pure water. The evaporator demonstrated exceptional stability, maintaining its evaporation capacity over 15 consecutive cycles of seawater desalination. Additionally, it exhibited remarkable salt-rejection performance, as evidenced by the rapid dissolution of 0.5 g of salt crystals pre-deposited on its surface under illumination. Moreover, the CuBTC-350 aerogel acts as a superior peroxymonosulfate (PMS) activator, facilitating the rapid generation of active species for the effective degradation of organic pollutants, such as tetracycline (TC) and methyl orange (MO). The synergistic coupling of solar desalination and catalytic oxidation in one integrated aerogel system offers a sustainable and versatile platform for comprehensive water treatment, harnessing solar energy simultaneously for freshwater production and contaminant destruction.
