In this study, a template-assisted method was successfully employed to derive NiCo layered double hydroxide nanoflowers (NiCo-LDH NFs) with a size of 400–600 nm from cobalt-zeolitic imidazolate framework (Co-ZIF) grown on carbon nanotubes (CNTs). These nanoflowers self-assembled on the CNTs into a distinctive three-dimensional (3D) lamellar architecture, resulting in the NiCo-LDH NFs/CNTs nanocomposite material, which was further leveraged to develop a novel nanozyme-based electrochemical glucose biosensor. The precise regulation of Ni2+ concentration facilitated the directional formation of NiCo-LDH into a 3D lamellar nanoflowers structure, effectively precluding the formation of disordered stacking configurations and thereby endowing it with a high specific surface area and abundant electrochemical active sites. In addition, the synergy between NiCo-LDH NFs and CNTs promoted efficient electron transfer during electrocatalysis, leading to excellent catalytic oxidation ability for glucose. With these merits, the NiCo-LDH NFs/CNTs showed a significant current response to various concentrations of glucose within the detection ranges of 0.5–1000 and 1000–5000 μM, having sensitivities of 1151 and 928.8 μA·mM–1·cm–2, respectively, with a limit of detection of 0.092 μM (S/N = 3). Moreover, the NiCo-LDH NFs/CNTs biosensor was successfully applied to the glucose detection of actual human serum samples, demonstrating the applicability of the biosensor and showing broad application prospects.

In this study, a novel C-ZIF-8@Fe/REEs composite, fabricated from one-step pyrolysis using ZIF-8@Fe adsorbed with rare earth elements (REEs) as precursors was successfully used to activate peroxymonosulfate (PMS) for efficient oxidation of Bisphenol A (BPA). The as-prepared C-ZIF-8@Fe/REEs exhibited high PMS activation performance, with an BPA removal efficiency exceeding 95 % within 120 min. Characterizations revealed that the REEs introduction increased the exposure of active sites, and facilitates the electron transfer. Electron paramagnetic resonance analysis and quenching tests confirmed that both radical (·OH, ·SO 4 − ) and non-radical ( 1 O 2 , high-valent metals, and electron transfer) pathways were involved in BPA degradation. Reasonable BPA degradation pathways were proposed by analyzing the results of LC-MS and DFT calculations. Additionally, toxicity assessments demonstrated a significant reduction in the toxicity of degradation products. Finally, the synthesized composite exhibited excellent reusability and stability in real wastewater fixed column bed experiments, with the removal efficiency still be higher than 70 % after 11 h operation. These findings demonstrate that the recovery REEs from mining wastewater is an effective strategy in developing a highly efficient Fenton-like catalysts, and also highlight the promising role of using C-ZIF-8@Fe/REEs in wastewater treatment, particularly for the removal of organic contaminants.

We demonstrate herein the ZIF-8-only-mediated catalysis of the cyclodimerization of epichlorohydrin to 2,5-bis(chloromethyl)-1,4-dioxane in the absence of co-catalyst and solvent. The easy handling and economic aspects of ZIF-8, in addition to the one-step reaction to produce the cyclodimer, make this catalyst attractive even for industry. It has been clearly illustrated that the nature of the method used to synthesize ZIF-8 affected the yields of the cyclodimers. Specifically, the method employed to produce ZIF-8 directly influences the amount of crystal structural defects, which in turn impacts their performance as catalysts. To emphasize the role of defects, other physical properties, such as surface area and particle size, were controlled during the synthesis of the ZIF-8 catalysts. Remarkably, the amount of structural defects was quantified by temperature program desorption analysis. Graphical A straightforward one-step cyclodimerization of epichlorohydrin using ZIF-8 as catalyst in the absence of solvent or co-catalyst is reported for the first time. It is shown that the nature of the method used to synthesize ZIF-8 strongly affects the yield of the cyclodimeric product. The acidic and basic properties of the ZIF-8 samples were determined by temperature program desorption analysis.

Airborne particulate matter (PM) pollution poses a serious threat to public health and the environment, underscoring the urgent need for advanced air filtration membranes that combine high efficiency with environmental sustainability. Although polylactic acid (PLA) nanofiber membranes (NFMs) are a promising eco-friendly potential, their electret instability and rapid performance decay limit practical application in air filtration. Inspired by the efficient predation mechanism of corals, we developed coral-like ZIF-8/PLA NFMs featuring a unique “skeleton-tentacle” architecture via controlled in situ secondary growth. This method enables precise regulation of ZIF-8 crystal size and distribution, maximizing active site exposure while preserving inter-fiber pores. The resulting ZIF-8/PLA NFMs exhibit a synergistic “electrostatic-adsorption, physical-interception, and chemical-interaction” capture mechanism, achieving a stable PM filtration efficiency of >99.78% over 2 h with only a moderate increase in pressure drop (from 155 to 217 Pa). The quality factor ( Q F ) reached 0.028 Pa −1 , which is 12 times higher than pure PLA NFMs. Moreover, the membranes also demonstrated excellent gas permeability (1214 m 3 ·m −2 ·h −1 ·kPa −1 ) and mechanical strength (4.0 MPa). In addition, the sterilization rates of ZIF-8/PLA NFMs against both E. coli and S. aureus reached 99.99%, indicating outstanding antibacterial performance. This work not only provides a high-performance, low-resistance, and sustainable air filtration membrane but also establishes a versatile biomimetic paradigm for integrating MOFs onto biodegradable polymers, thereby offering a promising route toward next-generation green filtration media.

Copper metal is prone to corrosion in aggressive environments, which poses a significant challenge to the long-term reliability. Herein, we report a self-healing slippery anticorrosion coating constructed on copper substrate. First, ZIF-8 with an ordered porous architecture was grown in situ by electrodeposition and used as a micro/nanoscale lubricant reservoir. ZIF-8 film was subsequently modified with thiol molecules to lower the surface energy for realizing superhydrophobicity. Finally, dimethyl silicone oil was infused into the thiolated ZIF-8 framework to form a ZIF-8-based slippery liquid-infused porous surface (SLIPS). Electrochemical measurements reveal that |Z| 0.01 Hz is 4.01 × 10 8 Ω·cm 2 . After being immersed in NaCl solution for 336 h, the SLIPS preserves |Z| 0.01 Hz close to 10 7 Ω·cm 2 . Even after pronounced mechanical scratching, |Z| 0.01Hz still remains high value. Anti-icing tests further revealed a low ice-adhesion strength of 113 ± 2 kPa, nearly one-sixth that of untreated copper (628 ± 7 kPa). These results demonstrate that the ZIF-8-based SLIPS provides high corrosion resistance, self-healing capability, and anti-icing performance, offering a robust barrier for long-term protection of copper-based materials in harsh corrosive environments.

Cross-substrate counter diffusion (CSCD) between imidazole and Zn(II)-loaded polyamide (PA) layers is carried out to in-situ grow zeolitic imidazole framework-leaf (ZIF-L) particles and improve the nanofiltration (NF) performances of negatively charged NF membranes. To achieve uniform distribution of Zn(II) in the formed PA layer, Cyclen was used to complex Zn(II) precursors during the interface polymerization (IP) between piperazine (PIP) and trimesoyl chloride (TMC) to dissolve the Zn(II)/PIP precipitation in the aqueous phase. Results showed that the addition of Cyclen improved the uniform dispersion and firm combination of ZIF-L particles (PTs) in the PA layers, improving both the water permeance and salt rejection of the formed TFN NF membranes. Under optimal conditions, TFN-PC 0.10-0.15 /ZIF membrane achieves a Na 2 SO 4 rejection of 90.2-96.8%, a pure water permeance of 25.8-32.8 L·m -2 ·h -1 ·bar -1 , a NaCl/Na 2 SO 4 mixed salt separation factor of 9.0-29.8, and good anti-fouling and operational stability.

In recent years, the development of intumescent fire-retardant coatings (IFRCs) has emerged as a critical strategy for enhancing fire safety in steel structures. However, traditional IFRCs exhibit limitations in meeting the demands of environmental protection, high-efficient fire resistance, and smoke suppression in construction applications. In this study, an organic-inorganic hybrid nanoflame retardant (HP@ZIF) was designed and synergistically applied with ammonium polyphosphate/triazine charring agent (APP/CFA) into an epoxy resin (EP) matrix, fabricating a high-performance IFRC. Back-surface temperature testing results suggested that HP@ZIF enhanced the thermal insulation of IFRC, which was also reflected in a significant increase in the char expansion ratio. The 20-min backside temperatures of the steel plate decreased from 576°C (uncoated steel) to 187°C (S3 coating), with the heat insulation efficiency of 67.5%, showing excellent fire retardant and thermal insulation performance of this EP coating. Additionally, total heat release (THR), total smoke release (TSR), and fire growth rate (FIGRA) of IFRC in the cone calorimeter test (CCT) were reduced by 70.1%, 72.0%, and 90.2%, respectively, demonstrating superior flame retardant and smoke suppression properties. Scanning electron microscopy (SEM) and Raman spectroscopy revealed that a dense, continuous char layer was formed after combustion, with enhanced mechanical integrity and thermal barrier functionality. More importantly, this EP coating maintained superior fire resistance after 7 d of water immersion. This study provides an economical and efficient solution for enhancing fire protection in modern buildings.

Although micro-arc oxidation (MAO) coatings improve the mechanical properties of titanium alloys, their porous structural defects tend to act as pathways for corrosive agents and as adhesion sites for contaminants. In this study, a superhydrophobic coating was developed on TC-4 titanium alloy by combining in-situ hydrothermal synthesis of ZIF-8 with POTS surface modification, thereby forming a rough surface with low surface energy. The POTS/ZIF-8@MAO composite coating exhibits strong adhesion to the substrate through both physical and chemical bonding. Consequently, it demonstrates excellent chemical and thermal stability, maintaining a water contact angle (WCA) of 156.53° ±2.47° and a sliding angle (SA) of 6.32° ±1.16° even under extreme conditions. Due to its low water adhesion, the coating demonstrates significant self-cleaning ability against both solid and liquid contaminants. Electrochemical analysis reveals that it improves corrosion inhibition by up to 99% compared to pristine MAO-treated titanium alloy, providing an effective protective barrier for the substrate. This work proposes a promising strategy that may potentially expand the application scope of titanium alloys.

In this work, a fluorescent sensor based on dual-emissive RhB/COF@ZIF-90 composite was fabricated for ratiometric detection of tetracycline (TC) residues in foods. To mitigate the aggregation-caused quenching (ACQ) effect of TAPB-DMTA COF, ZIF-90 on TAPB-DMTA COF composite was fabricated by an in situ growth strategy. Rhodamine B (RhB) was subsequently encapsulated within the ZIF-90 framework to construct a dual-emission fluorescent probe. When TC was present, the fluorescence signal at 460, 525 and 570 nm increased linearly with the amount of TC. The I 570 /I 460 and I 525 /I 570 ratio signals were demonstrated in the two linear ranges of 5–100 nM and 0.1–20 μM concentrations of TC, respectively. This multi-signal sensor exhibited a low detection limit of 0.29 nM, enabling highly sensitive detection of TC. Furthermore, this work paves the way for developing other MOF/COF hybrids as multi-emission fluorescent sensors for application in antibiotic sensing in foods.

A sensitive electrochemical sensor was proposed for neohesperidin dihydrochalcone (NHDC) detection using copper oxide/ zinc imidazole framework 8@ carbon nanotubes modified glassy carbon electrode (CuO/ZIF-8@CNTs GCE). The multi-component CuO/ZIF-8@CNTs GCE was prepared by two-step drop-casting method and characterized by Field-emission scanning electron microscopy (FE-SEM). The effective combination of CuO and ZIF-8@CNTs enhanced the electron transfer and catalytic activity of the electrode and greatly strengthened the oxidation current of NHDC, which was about 5.6-fold that of the CuO GCE and 2.3-fold that of the ZIF-8@CNTs GCE. Inspired by this, the CuO/ZIF-8@CNTs GCE was used for NHDC detection and some crucial parameters were optimized. The reaction mechanism at CuO/ZIF-8@CNTs GCE was confirmed to involve two-step two-electron process by cyclic voltammetry (CV) measurements. Finally, the sensor achieved NHDC detection ranging from 0.03 to 10 μM using differential pulse voltammetry (DPV) technique, with a detection limit of 16.0 nM. The satisfactory recoveries of 92.9–107.8 % in liquor samples also demonstrated its practicability in actual samples, matching well with that of high-performance liquid chromatography (HPLC). This work not only designs a simple detection method for NHDC but also opens up a paradigm for leveraging multi-component MOF composite electrode materials for food safety monitoring.

This study presents a facile one-pot hydrothermal strategy for the in-situ growth of a layered double hydroxide and ZIF-8 composite coating on anodic aluminum oxide. The synthesis temperature was optimized within the range of 110–130 °C, which enables the synchronous formation of a uniform and well-interlocked LDH/ZIF-8 microstructure. Subsequent modification with stearic acid (SA) effectively imparts hydrophobicity to the coating, yielding a water contact angle of 136.4 ± 0.10°. The obtained LDH/ZIF-8@SA coating exhibits remarkable anti-icing performance, delaying ice nucleation and complete freezing of a water droplet at -15 °C by 93% and 45%, respectively, compared to the bare AAO substrate. Electrochemical tests demonstrate excellent corrosion resistance, with the SA-modified coating showing a corrosion current density of 1.413 × 10 -9 A·cm -2 after 3 days of immersion, and a charge-transfer resistance up to 1.362 × 10 8 Ω·cm 2 after 14 days of immersion in 3.5 wt.% NaCl solution. Moreover, the coating possesses a low friction coefficient of 0.318 ± 0.045. Density functional theory calculations were performed to elucidate the interfacial bonding mechanism among ZIF-8, SA and LDH.

Osteomyelitis is a devastating bone disease caused by bacterial infection, the treatment of which remains challenging due to bacterial biofilm formation and impaired bone regeneration. The development of an integrated therapeutic platform capable of locally filling bone defects, enabling controlled drug release and modulating the infectious microenvironment is of crucial importance. This study constructed an injectable self-healing hydrogel based on Schiff base bonds for pH-triggered delivery of ZIF-8-loaded curcumin, aiming to achieve synergistic therapy for osteomyelitis. Curcumin-encapsulated zeolitic imidazolate framework-8 nanoparticles were synthesized via a one-pot method and embedded into an oxidized starch–gelatin hydrogel network formed by dynamic Schiff base crosslinking, yielding the composite hydrogel. Systematic characterization revealed that the ZIF-8@Cur nanoparticles exhibited a well-defined rhombic dodecahedral structure, high crystallinity and a curcumin encapsulation efficiency of 85%. The composite hydrogel demonstrated excellent injectability, rapid self-healing behavior and remarkable pH-responsive drug release: under the acidic condition mimicking an infectious microenvironment (pH 5.5), the cumulative release over 72 h reached 85%, significantly higher than the 25% observed at physiological pH 7.4. In vitro antibacterial assays confirmed its potent broad-spectrum antibacterial activity against both Gram-positive and Gram-negative bacteria ( > 98% inhibition). More importantly, the system effectively promoted macrophage polarization from pro-inflammatory M1 to anti-inflammatory and reparative M2 phenotypes while exhibiting good biocompatibility. This study successfully developed an intelligent responsive injectable hydrogel delivery system integrating efficient antibacterial, anti-inflammatory and immunomodulatory functions, offering a promising strategy for the comprehensive local treatment of osteomyelitis.
