Methyl parathion (MP) is a highly toxic organophosphorus pesticide and poses a serious threat to food safety and public health. Herein, an integrated sensing platform combining hollow Mn-doped ZIF-67 with carboxylated carbon nanotubes to form a heterojunction (H-Mn/ZIF-67@COOH-CNTs) was successfully fabricated for sensitive recognition and ultrafast removal of MP. The constructed sensing platform demonstrated excellent analytical performance for MP under optimized conditions, featuring a broad linear range of 0.3–100 μM and a low detection limit of 0.024 μM. Furthermore, H-Mn/ZIF-67@COOH-CNTs achieved rapid removal of MP. The Langmuir fitting yielded a theoretical maximum adsorption capacity of 584.8 mg·g −1 , while a removal efficiency of 92.52% was achieved within 5 min. This research provides a reliable platform for the sensitive detection of MP in fruits and vegetables and its rapid removal from aqueous solutions, while offering novel insights for designing high-performance electrocatalysts in environmental monitoring and food safety testing.

Lithium-sulfur batteries (LSBs) are considered a promising class of energy storage devices due to their high theoretical energy density and specific capacity. Key challenges to improving LSB performance include mitigating the shuttle effect of soluble polysulfides (LiPSs) and enhancing the conductivity of the sulfur cathode. In this study, we present a tubular material composed of porous nitrogen-doped carbon (PNC) and nitrogen-doped carbon nanotubes (NCNT) as a sulfur host (PNC/NCNT). The porous structure of PNC/NCNT provides abundant space for sulfur accommodation, while its disordered mesoporous structure and high electronic conductivity help alleviate the shuttle effect of LiPSs through nitrogen-induced defects and active sites. As a result, the PNC/NCNT/S cathode significantly enhances the poor electrical conductivity of sulfur cathodes, offering improved rate performance and robust cycling stability, with a capacity retention of 859.1 mAh g −1 after 500 cycles at 1 C and a minimal capacity fading of 0.031 % per cycle.

Diabetic wounds represent one of the most prevalent complications in patients with diabetes mellitus. Elevated reactive oxygen species (ROS), bacterial infections, persistent inflammation, and impaired angiogenesis collectively contribute to delayed diabetic wound healing. In this study, a multifunctional, injectable, photoinitiator-free, photocrosslinkable hydrogel (G/Z@M) based on insect-derived chitosan was developed. The hydrogel system incorporated lipoic acid (LA), which possesses photopolymerization capability and potent antioxidant activity, to modify quaternized chitosan (QMCS). Through self-initiated photo-crosslinking of QMCS-LA, the hydrogel's three-dimensional network was constructed. Simultaneously, the ZIF-8@MPN nanocomposite was constructed by coating ZIF-8 with a metal-polyphenol network (MPN) functional coating formed through the coordination of epigallocatechin gallate (EGCG) with Ga 3+ . This nanocomposite was then loaded onto the QMCS-LA network. Both in vitro and in vivo experiments demonstrated that the G/Z@M hydrogel possesses great biocompatibility, antibacterial, anti-inflammatory, antioxidant, and pro-angiogenic activities, effectively promoting the healing of full-thickness skin defect wounds in MRSA-infected diabetic rats. In conclusion, the G/Z@M hydrogel presents an innovative therapeutic approach for diabetic infected wounds by simultaneously regulating oxidative stress, bacterial infection, persistent inflammation, and impaired angiogenesis.

The clinical translation of urolithin A (UA), an ellagitannin-derived metabolite with antioxidant and mitophagy-inducing properties, is hampered by its poor solubility, limited stability, and low oral bioavailability. To address these limitations, we developed a core-shell nanoplatform (UA@ZIF-8@CMG) comprising a ZIF-8 core for efficient encapsulation and a carboxymethyl β-glucan (CMG) shell for enhanced stability and potential targeting. The optimized formulation exhibited a high drug-loading capacity (12.65 %), markedly improved UA stability, and demonstrated pH-responsive release, with minimal leakage (22 %) under simulated gastric conditions followed by sustained release in the intestinal environment. In vitro studies revealed reduced cytotoxicity and a dual cellular uptake mechanism, involving putative Dectin-1-mediated endocytosis in macrophages and nonspecific uptake in intestinal cells. This uptake profile resulted in superior preservation of mitochondrial membrane potential and more effective ROS scavenging compared with free UA. The key innovation of this system lies in the synergistic ZIF-8@CMG architecture, which integrates robust protection, controlled release, and cell-type-specific uptake, thereby distinguishing it from previously reported delivery platforms. Collectively, this work presents a translatable strategy to enhance UA bioavailability and therapeutic performance, underscoring its promise for both nutraceutical and pharmaceutical applications.

2-Methyl imidazole and Zn(NO 3 ) 2 were proposed as raw materials for the hemoglobin (Hb) accommodation matrix ZIF-8, and the encapsulation of Hb molecules onto ZIF-8 was achieved by hydrogen bond interaction and electrostatic attraction. The electrochemical sensing performance of H 2 O 2 for Hb integration into metal–organic framework (MOF) material was analyzed systematically and evaluated quantitatively to identify the key factor in limiting the sensing efficiency. The influence of mutual interactions between Hb and ZIF-8 on the spectroscopic features and sensing efficiency for complexes with Hb incorporation was estimated by multiple techniques to explore the impact of those interactions on the relevant steps involved in the catalysis. The results from experiments revealed that the hydrogen bond between Hb and ZIF-8 led to non-oriented aggregation of enzyme molecules onto the MOF with reduced active surface area and inhibited catalytic activity. The relatively weak interaction between heme protein and MOF material did not result in serious distortion in the structure or chemical nature of Hb entrapment into ZIF-8. The presence of a mutual interaction between Hb and ZIF-8 did not impose a serious negative effect on heterogeneous electron shuttle (28.2–91.2 s −1 ) for the heme site in Hb entrapment into ZIF-8, which was classified into a typical quasi-reversible and thin-film confining mode with the involvement of four electrons and two H + ions. The results showed that hb-induced electrocatalysis was limited by the step of substrate diffusion (1.3 × 10 −3 s −1 ). The Hb-based electrode demonstrated excellent affinity to dissolved H 2 O 2 (Michaelis constant: 28.0 μM) and desirable sensing performance (low detection limitation: 3.7 μM). Graphical Abstract Illustration of the procedure for preparing the electrode based on MOF material (ZIF-8) with hemoglobin accommodation via physical adsorption and electrostatic attraction, which gives rise to non-oriented distribution of hemoglobin attachment onto the surface and inner cavity of ZIF-8.

Ratiometric optical thermometry has emerged as a vital platform for non-contact temperature monitoring in industrial and scientific applications, demanding sensors with high sensitivity, non-invasiveness, and spatial resolution. Although zeolitic imidazolate framework-8 (ZIF-8) possesses attractive thermal stability and structural tunability, its limited luminescence intensity hinders practical thermometric applications. Meanwhile, ZIF-L, a two-dimensional (2D) polymorph of ZIF-8 with identical ligands, remains unexplored for temperature sensing. Herein, we propose a dual-modulation strategy synergizing lanthanide valence engineering with MOF phase control to develop a multi-emission center Eu3+/Eu2+ co-doped ZIF-L film (Eu/ZIF-L). By introducing Eu3+ into ZIF-8 precursors, the partial reduction of Eu3+ to Eu2+ under thermal treatment triggers a structural evolution from 3D ZIF-8 to 2D ZIF-L. The resultant Eu/ZIF-L exhibits dual emission peaks at 450 nm (Eu2+) and 495 nm (ligand-centered), with their intensity ratio (I495/I450) demonstrating remarkable linear temperature dependence over 296–373 K and achieving a relative sensitivity of 1.95% K−1. This work pioneers the integration of valence-state manipulation and MOF phase transition for thermometric optimization, providing a novel paradigm to design advanced ratiometric MOF thermometers for industrial thermal management.

PM6 is a polymer donor characterized by a wide bandgap, commonly utilized in high-performance polymer solar cells. In this study, we applied PM6 to the field of electrochemiluminescence for the first time. By sequentially modifying PM6, CS@luminol and ZIF-8 on the electrode, we constructed a simple yet novel electrochemiluminescence (ECL) sensor for the detection of the colorant sunset yellow (SY). As a donor, PM6 enhanced the charge transfer rate within the system and improved its luminescence performance. CS served to stabilize the luminescent reagent due to its viscosity. ZIF-8 acted as an accelerator in the luminol luminescence system, facilitating the absorption of more active oxygen and generating additional reactive species on the electrode surface. The combined action of PM6 and ZIF-8 resulted in a luminol ECL sensor that exhibited a sensitive and stable signal. When exposed to sunset yellow, the ECL signal diminished consistently with increasing concentrations of SY. Under optimal conditions, the ECL attenuation signal demonstrated a linear relationship with the logarithm of SY concentration, with a linear range of 5.0 × 10 − 13 –5.0 × 10 − 8 mol L -1 , and a detection limit of 1.67 × 10 −13 mol L -1 (S/N = 3). The constructed sensor exhibited excellent stability, selectivity, and repeatability, making it suitable for the actual detection of sunset yellow in sports drinks.

The zeolitic imidazolate framework (ZIF) is characterized by a highly ordered structure, large cavities, and thermal/chemical stabilities and has been widely researched for energy storage. In this study, using commercial Si powder with a diameter of 50–200 nm at a kilogram scale, Si@ZIF core-shell particles with dispersed ZIF-8 rhombic dodecahedrons were fabricated by a one-pot method and achieved excellent electrochemical performance. With the specific pore diameter and ordered network formed by membered rings, experimental results demonstrated that the ZIF-8 shell realized a uniform and accelerated Li + diffusion route, alleviated volumetric expansion of the Si core, and constructed a LiF-concentrated robust solid electrolyte interface film with less unnecessary consumption of electrolyte and Li + . Density functional theory calculations verified the higher adsorption energy for Li-solvated clusters and the de-solvation effect on the surface of ZIF-8, which can increase Li + concentration along the one-dimensional channels of 4-membered ring with a diameter similar to that of Li + for high-speed and uniform Li + intercalation. Furthermore, the large and elastic rhombic dodecahedrons formed by pure ZIF-8 buffered the volume change and maintained the integrity of the Si electrode during cycling. As a result, the Si@8Z anode achieved a reversible capacity of 818.5 mAh g −1 after 650 cycles at 1 A g −1 with a high initial coulombic efficiency of 88.2 % and outstanding rater performance even at 8 A g −1 . Nevertheless, the capacity of the Si anode decreased to 0 mAh g −1 after 200 cycles. The present work clarifies the effect of ZIF on the performance of Si anodes and provides a simple method to modify commercial Si powder.

Enhancing both the number of active sites available and the intrinsic activity of Co-based electrocatalysts simultaneously is a desirable goal. Herein, a ZIF-67-derived hierarchical porous cobalt sulfide decorated by Au nanoparticles (NPs) (denoted as HP-Au@Co x S y @ZIF-67) hybrid is synthesized by low-temperature sulfuration treatment. The well-defined macroporous–mesoporous–microporous structure is obtained based on the combination of polystyrene spheres, as-formed Co x S y nanosheets, and ZIF-67 frameworks. This novel three-dimensional hierarchical structure significantly enlarges the three-phase interfaces, accelerating the mass transfer and exposing the active centers for oxygen evolution reaction. The electronic structure of Co is modulated by Au through charge transfer, and a series of experiments, together with theoretical analysis, is performed to ascertain the electronic modulation of Co by Au. Meanwhile, HP-Au@Co x S y @ZIF-67 catalysts with different amounts of Au were synthesized, wherein Au and NaBH 4 reductant result in an interesting “competition effect” to regulate the relative ratio of Co 2+ /Co 3+ , and moderate Au assists the electrochemical performance to reach the highest value. Consequently, the optimized HP-Au@Co x S y @ZIF-67 exhibits a low overpotential of 340 mV at 10 mA cm –2 and a Tafel slope of 42 mV dec –1 for OER in 0.1 M aqueous KOH, enabling efficient water splitting and Zn–air battery performance. The work here highlights the pivotal roles of both microstructural and electronic modulation in enhancing electrocatalytic activity and presents a feasible strategy for designing and optimizing advanced electrocatalysts.

Superwetting membrane have gained significant attention as a highly effective solution for oily wastewater treatment. However, its effectiveness was restricted when separating different types of oil-in-water (O/W) and water-in-oil (W/O) emulsions due to the limited single wettability of the membrane surfaces. Developing superwetting membranes with broad applicability and high separation efficiency is crucial for the continued advancement of membrane separation technology. In this study, a hydrophilic polymer, poly 2-hydroxybutyl methacrylate (PHBMA) was introduced into the polyacrylonitrile (PAN) substrate, and zeolitic imidazolate framework-90 (ZIF-90) particles were synchronously grown and in-situ immobilized on the membrane surface in process of phase inversion, forming a ZIF-90@P-PAN membrane with switchable superwettability. With increasing ZIF-90 growth time, the membrane surface first became rougher due to crystal formation, then gradually denser as particle accumulation increased. This membrane exhibited super-amphiphilicity in air and super-amphiphobicity under liquid, demonstrating high permeation flux and excellent separation efficiency (>99 %) for different types of emulsions. The effects of ZIF-90 particles with different growth times on the membrane morphology, wettability and oil–water separation performance were systematically studied. Additionally, the removal efficiency (>80 %) and recycling performance of the ZIF-90@P-PAN membrane for four different heavy metal ions were investigated. This work contributed to the development of superwetting membranes for efficient recovery of oily wastewater.

Porous membranes have been fabricated and modified for the separation and purification of wastewater. Although they always suffer from fouling caused by various materials such as oils, dyes, and antibiotics. It is difficult to deal with the boring membrane fouling by one antifouling strategy including hydrophilicity/underwater superoleophobicity. In this work, a synergistic antifouling mechanism combining low oil adhesive underwater superoleophobicity and excellent persulfate advanced oxidation processes (PS-AOPs) performances was developed by facilely loading ZIF-67 catalysts on polypropylene (PP) membranes. The as-prepared composite membranes have stable underwater superoleophobicity and low oil adhesion, which can efficiently separate oil from oil-in-water emulsion and prevent oil adhesion. Moreover, the ZIF-67 catalysts on the composite membranes have excellent degradation performances against various foulants such as methylene blue (MB), tetracycline (TC), and levofloxacin (LVFX), which endow the composite membrane with enhanced antifouling properties during the separation of an oil-in-water emulsion containing MB, TC, and LVFX. The synergistic antifouling mechanism of low oil adhesive underwater superoleophobicity and advanced PS-AOPs provides a facile and efficient strategy for improving the antifouling of the porous membranes in real wastewater purification.

A novel nitrogen-doped porous carbon catalyst (NCW) was synthesized via in-situ growth of ZIF-8 on balsa sawdust followed by controlled carbonization. The integration of ZIF-8 significantly increased specific surface area, defect density, and electrochemical activity, while nitrogen incorporation—especially pyridinic and graphitic species—enhanced 2e − oxygen reduction reaction (ORR) selectivity, achieving an exceptional H 2 O 2 selectivity of 94%. When immobilized on a graphite cathode and paired with a boron-doped diamond (BDD) anode, the NCW-based electro-Fenton (EF) system enabled robust in-situ H 2 O 2 generation and efficient tetracycline (TC) degradation. Under optimized conditions, the system achieved a maximum H 2 O 2 accumulation of 0.73 mmol L −1 , completed TC removal within 120 min, and a total organic carbon (TOC) mineralization efficiency of 84.6% after 4 h. Quenching experiments and electron paramagnetic resonance (EPR) spectroscopy identified homogeneous and heterogeneous hydroxyl radicals (·OH) and superoxide radicals ( ‐ O 2 · ‐ ) as the key reactive species. The NCW/BDD/EF system demonstrated excellent versatility across various organic pollutants and maintains robust reusability over multiple cycles. This work presents a sustainable strategy for developing wood-derived electro-Fenton catalysts for efficient antibiotic wastewater treatment.
