Rotating packed bed (RPB) is firstly used for chemical synthesis of heterojunction. • ZnO/ZIF-8 heterojunctions achieve a record catalytic activity in PLA methanolysis. • RPB product has more oxygen vacancies and stronger Lewis acid than counterpart. • Lewis acid of ZnO and high surface area of ZIF-8 endow catalyst high activity. • Excellent activity covers various real-life polyester wastes and their mixtures. The chemical recycling of plastic is crucial for achieving a circular economy, and developing heterogeneous catalysts that combine high activity with structural stability represents a pivotal challenge. Herein, a high-gravity-assisted approach was proposed to efficiently construct ZnO/ZIF-8 (RPB-ZnO/ZIF-8) nanoheterojunctions enriched with oxygen vacancies (Ov) for polylactic acid (PLA) methanolysis to methyl lactate (MeLA). Compared to the stirred tank (ST), high-gravity synthesis drastically reduces coordination reaction time from 1 h to an extremely short time (< 1 s). The as-prepared RPB-ZnO/ZIF-8 catalyst achieved 100% PLA conversion at 100 °C in 0.5 h with a MeLA yield of 95.6%, reaching the highest activity compared to previous works so far. More importantly, it demonstrated excellent cycle stability, maintaining >92% of its initial activity after five cycles. Catalytic mechanistic investigations reveal that the Ov increases Lewis acidity of the heterojunction surface, thereby facilitating the reactants adsorption and activation, which leads to a reduction in the energy barrier for PLA methanolysis. Furthermore, RPB-ZnO/ZIF-8 catalyzes the depolymerization of other plastics effectively (e.g., polyethylene terephthalate and polycarbonate) and demonstrates remarkable versatility in converting various real-life polyester wastes and their mixtures. This study presents an efficient strategy for advancements in sustainable plastic recycling.

Enrofloxacin residues in foods pose potential risks to food safety and public health, creating demand for rapid, sensitive, and matrix-compatible screening methods. All-inorganic CsPbBr3quantum dots (QDs) are promising fluorescent probes because of their strong photoluminescence, but their poor stability in polar media greatly restricts their practical use in food analysis. Herein, ZIF-8-confined and APTES-passivated CsPbBr3QDs were developed as an ethanol-compatible fluorescent sensor for enrofloxacin detection in foods. Unlike reported CsPbBr3@ZIF-8 systems mainly used for metal-ion sensing in aqueous media, this work integrates ZIF-8-confined in-situ growth with APTES-assisted silane passivation to improve the stability and applicability of CsPbBr3QDs in ethanol-based food extracts. ZIF-8 provided a confined microenvironment, while the APTES-derived silane layer further enhanced fluorescence stability. The sensor exhibited a distinct turn-off fluorescence response toward enrofloxacin, with a linear range of 0.1–25.0 mg·L−1and a limit of detection of 0.058 mg·L−1, mainly attributed to electron transfer with CsPbBr3@ZIF-8. The method was successfully applied to honey, milk, fish, and shrimp samples, achieving recoveries of 85.2–106.8%. Results obtained for aquatic products showed no significant difference from HPLC analysis (p> 0.05), demonstrating the potential of this sensor for rapid enrofloxacin residue screening in complex food matrices.

Natural antibacterial food packaging materials endowed with environmental responsiveness are garnering substantial research interest in sustainable food preservation. This study reports the development of a pH-responsive antimicrobial composite film through encapsulation of eugenol—a natural phenolic compound—within zeolitic imidazolate framework-8 (ZIF-8). The engineered eugenol@ZIF-8 system demonstrated pH-dependent release characteristics, with cumulative release reaching 32.2% at pH 6 versus merely 0.61% at pH 7 over 4 h. Subsequent integration of this nanocarrier into a polyvinyl alcohol (PVA)/hydroxypropyltrimethyl ammonium chloride chitosan (HACC) matrix yielded a multifunctional composite film for active food packaging applications. The characterization of film revealed that while eugenol@ZIF-8 incorporation slightly compromised mechanical strength (tensile resistance decreased by 18.7%) and flexibility (elongation at break reduced to 54.3% of control), it significantly enhanced hydrophobicity (water contact angle increased to 92.5°) and thermal stability (decomposition temperature elevated by 34 °C). The composite film demonstrated synergistic antibacterial efficacy through the combined action of Zn2+ions, ZIF-8 nanostructures, and eugenol, achieving 88% inhibition againstE. coli.Practical validation through fresh noodle preservation trials confirmed the material’s effectiveness, with the optimized formulation (PVA-HACC-2% eugenol@ZIF-8, PHEZ2) extending shelf life by >5 days compared to conventional packaging. This work establishes a novel strategy for engineering intelligent ZIF-based packaging systems that respond to food spoilage microenvironments, offering significant potential for reducing food loss.

Sensitive detection of metabolites in biofluids is fundamentally limited by surface-related challenges, including insufficient enrichment, nonspecific adsorption, and poor interfacial durability. Here, we report an interface-engineering strategy for surface plasmon resonance (SPR) biosensors based on tri-functional Au@ZIF-8 core–shell nanostructures. By integrating plasmonic enhancement, molecular sieving, and photocatalytic activity into a single interface, the architecture simultaneously addresses trade-offs between sensitivity, selectivity, and reusability. The ZIF-8 shell serves as a size-selective molecular sieve for target enrichment and protein exclusion, while the plasmonic Au core provides electromagnetic field enhancement and enables light-driven degradation of adsorbed species. Finite element simulations were employed to analyze the interfacial optical response and near-field distribution, quantitatively revealing the interplay between field confinement and molecular capture volume to identify an optimal shell thickness. This interface, integrated onto a tilted fiber Bragg grating (TFBG)-SPR platform, was validated using uric acid. The system exhibits a detection limit of 3.28 × 10 −10 M, 93.4% recovery in artificial serum, and over 92.2% signal retention after ten visible-light-driven regeneration cycles. This work establishes a generalizable, robust, and regenerable interface framework for high-fidelity sensing in complex biological environments.

Conventional cervical cancer therapies often cause severe side effects and face recurrence challenges. Although the natural flavonoid fisetin (FIS) exhibits strong anticancer properties, its clinical utility is restricted by poor aqueous solubility. To overcome this, we engineered a tumor-targeting nanotherapeutic, PEG-FA@ZIF-8@FIS, by encapsulating FIS within a zeolitic imidazolate framework-8 (ZIF-8) core surface-functionalized with polyethylene glycol-folic acid(PEG-FA). Both in vitro and in vivo models demonstrate that this system effectively suppresses cancer cell proliferation, migration, and tumor growth with excellent biocompatibility. Mechanistically, transcriptomic and lipidomic analyses reveal that PEG-FA@ZIF-8@FIS exerts its anticancer effects by downregulating aquaporin-3 (AQP3) expression, which subsequently disrupts tumor lipid metabolism. By linking AQP3 inhibition to metabolic impairment via a targeted delivery platform, this work establishes a highly biocompatible and effective translational strategy for cervical cancer intervention.

ZIF-8 have been extensively studied in water treatment membranes, and they exhibit excellent modification effects in the membranes. In this study, tea polyphenol-coated ZIF-8 nanoparticles are synthesized via one-pot synthesis and then are blended to modify polyethersulfone ultrafiltration membrane. The shape of the nanoparticles is affected by changing the content of tea polyphenol. Different nanoparticles blends polyethersulfone for ultrafiltration membranes. It is found that adding ZIF-8@Tea polyphenol with hydrophilic properties could significantly improve wettability of membrane; when 0.3 g of ZIF-8@Tea polyphenol is added, the film contact angle decreases to 27.3 ° and shows an excellent rejection rate for methylene blue, methyl orange, and Congo red. The addition of ZIF-8 significantly enhances the retention rate of bovine serum albumin by water treatment membranes, which is mainly attributed to its precise size sieving effect. The accumulation or growth of ZIF-8 particles creates more uniform nanoscale channels, ultimately reducing the average and maximum pore diameters. The effective separation layer of membranes make much smaller than the size of bovine serum albumin. The strategy not only enables the ultrafiltration membrane to maintain high water flux under different pressures but also endows it with the ability to resist Escherichia coli microorganisms.

Polymer transport resistance was tuned by controlling the solvent evaporation rate. • Reduced polymer transport resistance promoted a more effective contribution of ZIF-8 transport pathways to CO 2 /N 2 separation. • The 7.8 wt% in situ-grown MMM achieved a CO 2 permeability of 510 Barrer and a CO 2 /N 2 selectivity of 33.0. Beyond filler modification, regulating the polymer structure is also crucial for optimizing gas transport in mixed-matrix membranes (MMMs), yet this aspect remains insufficiently explored. Herein, the solvent evaporation rate was controlled to regulate the transport resistance of Pebax 2533 and elucidate its influence on the transport contribution of ZIF-8 in ZIF-8/Pebax MMMs for CO 2 /N 2 separation. For Pebax 2533 membranes, increasing the evaporation rate reduced both crystallinity and relative fractional free volume, resulting in a non-monotonic variation in CO 2 permeability and a decrease in CO 2 /N 2 selectivity. At a moderate evaporation rate of 2.5 × 10 −5 kg·m −2 ·s −1 , the balance between reduced crystallinity and preserved free volume resulted in lower polymer transport resistance, enabling the contribution of ZIF-8 to be more effectively translated into membrane separation performance. As a result, the in situ-grown MMM containing 7.8 wt% ZIF-8 achieved a CO 2 permeability of 510.0 Barrer and a CO 2 /N 2 selectivity of 33.0, with its CO 2 permeability exceeding that of most reported Pebax-based MMMs. This work demonstrates that controlling solvent evaporation is an effective strategy to regulate polymer transport resistance and enhance the contribution of ZIF-8 in MMMs. Download: Download high-res image (207KB) Download: Download full-size image

A Pd-ZnO@ZIF-8 heterostructured benzene gas-sensitive material was prepared. • The benzene sensor has a low detection limit, rapid detection and high stability. • Vision-olfactory robots have achieved intelligent inspection of leakage risks. Benzene (C 6 H 6 ) is a volatile organic compound with strong carcinogenicity, and achieving its rapid and sensitive detection is of great significance for environmental protection and the prevention and control of public health risks. In this study, a ternary heterostructure gas-sensing material composed of Pd-modified ZnO@ZIF-8 was proposed. The pre-concentration effect of ZIF-8, the catalytic sensitization of Pd nanoparticles, and the construction of the Schottky barrier at the Pd/ZIF-8 interface collectively endow the sensor with excellent detection performance. This sensor exhibits extremely high sensitivity at 375℃, with a rapid detection speed (response/recovery time of 2 s/2 s) and an extremely low detection limit (capable of reaching the ppb level). Meanwhile, based on this sensor, a pipeline condition monitoring platform was developed. On the mobile end, online monitoring of benzene leakage and graded early warning were realized. Furthermore, this detection system is integrated with robots. Through a combined olfactory and visual detection method, it enables intelligent inspection of the risks of gaseous and liquid benzene leakage. Therefore, the proposed Pd-ZnO@ZIF-8 sensor and its integrated monitoring platform offer a reliable and efficient solution for real-time benzene leakage detection, holding great promise for enhancing industrial safety and public health protection.

GOx@ZIF-90@CuCo-MOF composite was synthesized via synergistic self-assembly. • Bimetallic sites and ZIF-90 shell significantly enhanced nanozyme activity. • The GOx@ZIF-90@CuCo-MOF paper-based nanozyme sensor was fabricated for rapid and noninvasive glucose detection in saliva. • The sensor achieved a 13.5 μM detection limit within a 20-min reaction. Glucose biosensors are pivotal to diabetes management; however, traditional fingerstick blood collection methods are often challenging due to their invasiveness, pain, high cost, and inability to provide continuous monitoring. Here, we constructed a paper-based colorimetric sensing platform using a multifunctional metal–organic framework (MOF) composite system to enable rapid, noninvasive detection of glucose in saliva. This platform utilized a CuCo-MOF framework, loaded with glucose oxidase (GOx) and ZIF-90 via a synergistic self-assembly mechanism, to catalyze the colorimetric reaction of H 2 O 2 and tetramethylbenzidine (TMB). The synergistic effect of the composite significantly enhanced the overall catalytic efficiency, enabling a sensitive response to glucose levels in saliva. Using ImageJ, color images captured with a smartphone were analyzed using RGB color channels to quantitatively determine glucose levels in saliva. The detection time was 20 min, with a detection limit (LOD) of 13.5 μM and a linear range of 50–2000 μM. This platform offered advantages with the absence of blood sample collection, ease of operation, and visual response. It provided new material strategies and design ideas for developing portable, non-invasive blood glucose monitoring technology.

Biomimetic ZIF-L/MXene were prepared by a facile two-step synthetic route. • Microflower structure favors light harvesting and active site exposure. • MXene can expand the photoresponse into the near-infrared region. • ZIF-L/MX-0.8 achieves efficient photodriven CO2 fixation under ambient conditions. • The photothermal/photocatalytic synergistic mechanism was explored. Solar-driven carbon dioxide (CO 2 ) transformation into valuable carbon-based products is of high significance for simulating natural carbon cycling. However, the ongoing challenge lies in the design of photocatalysts for achieving efficient CO 2 conversion. In this study, inspired by natural wisdom, ZIF-dia/MXene microflowers are successfully constructed through [Zn(NH 3 ) 4 ] 2+ -induced self-assembly of Ti 3 C 2 T x MXene (T x = –F, –OH, =O) sheets followed by the in-situ growth of ZIF-DIA. Remarkably, the optimized ZIF-dia/MX-0.8 serving as a solar-triggered photothermal and photocatalytic bifunctional platform was found to catalyze the coupling of CO 2 and epichlorohydrin, with a cyclic carbonate yield of 98% under full spectrum illumination for 6 h, significantly surpassing the single components. Specifically, the hierarchical flower-like superstructure consisting of ZIF-dia and MXene sheets can favor light absorbance via multiple reflection and facilitate the exposure of active sites and mass transfer. In addition, this ZIF-dia/MXene composite can absorb the light covering the entire visible region owing to the presence of MXene, thereby enhancing the photothermal conversion. Furthermore, experimental results reveal that the CO 2 cycloaddition with epoxide over ZIF-dia/MX-0.8 is proved to be the synergy of photothermal catalysis and photocatalysis. This work enriches the design of MOF-containing photocatalysts, opening a unique and sustainable way to solve global environmental issues.

Current adsorbents for bisphenol A (BPA) require complex preparation and relatively low adsorption capacities. Here, a high-performance adsorbent (Fe-N-C) was synthesized from iron-modified zeolite imidazole frameworks-8 (ZIF-8) via pyrolysis. With an exceptionally high specific surface area of 1565.15 m 2 ·g −1 , Fe-N-C removed 90% of BPA within 10 min and achieved adsorption equilibrium within 3 h. Furthermore, Fe-N-C exhibited a maximum BPA theoretical adsorption capacity of 877.45 mg·g −1 (288 K). The adsorption kinetics and isotherms conform to pseudo-second-order kinetics and the Langmuir model. Fe-N-C also demonstrated excellent performance across a wide pH range (4–10) and in complex water matrix. The high adsorption capacity was primarily attributed to π-π interactions, along with hydrogen bonding, electrostatic interactions, and hydrophobic interactions. Notably, in addition to efficiently adsorbing BPA, Fe-N-C exhibited a high selectivity toward organic compounds with two benzene rings by π-π interactions, such as bisphenol B (BPB), 2,2-bis (4-aminophenyl) propane (BAPP) and diclofenac (DCF) due to the mediation of graphitized microdomains. This study provides a simple route to prepare high-capacity N-doped carbon adsorbents for the selective and rapid adsorption of specific structural pollutants.

Hydrogen is an ideal safe and clean energy source, which can be produced by the electrocatalytic hydrogen evolution reaction (HER). The high overpotential of HER is one of bottlenecks for practical application, thus efficient and stable electrocatalysts, especially inexpensive electrocatalysts, are being vigorously developed to facilitate the reaction. Herein, we report the rational synthesis of a non-noble transition metal electrocatalyst via combined self-assembly and ion-exchange strategy. Zeolitic Imidazolate Framework-67 (ZIF-67) was in-situ grown on the surface of polypyrrole-derived nitrogen-doped carbon nanotubes (N-CNT) through a self-assembly method and then ZIF-67 was transformed into a CoMo layered double hydroxide (CoMo-LDH) through an ion-exchange reaction. As a result, a nanocomposite with N-CNT as the core and CoMo-LDH as the shell (N-CNT@CoMo-LDH) was successfully synthesized. The optimal N-CNT@CoMo-LDH exhibits excellent HER performance with a low overpotential of 86 mV at 10 mA cm −2 in 1 M KOH, superior to ZIF-67, CoMo-LDH, N-CNT@ZIF-67 and many reported LDH-based electrocatalysts. Additionally, the N-CNT@CoMo-LDH maintains approximately 86% of its initial current density after 24-h continuous test, with an overpotential increase of only 9 mV after 3000 cycles. The improved electrocatalytic HER performance is primarily attributed to the synergistic interaction between Mo 6+ and Co 2+ /Co 3+ , facilitating the formation of active sites, and N-CNT as core to enhance electron transport rates and inhibit the stacking of CoMo-LDH nanosheets, thus exposing more active sites of CoMo-LDH. Furthermore, its HER is confirmed to be the Volmer-Heyrovsky mechanism. This work provides a promising pathway for synthesizing highly efficient and stable electrocatalysts based on inexpensive non-noble metals.
