The oxygen evolution reaction (OER) requires the development of a strong and efficient electrocatalyst due to its slow mechanism and high overpotential. Hence, we assembled POM and NiCo-ZIF-67 to obtain the amorphous hollow core-shell material NiCo-ZIF-67@POM (donated as NiCo-ZIF@POM) with high catalytic activity. NiCo-ZIF@POM (1:3) presents a low overpotential (η≈150 mV@10 mA cm-2), a small Tafel slope (100 mV dec-1), and great stability for OER in 1 M KOH solution. Theoretical calculations indicate that the excellent activity of NiCo-ZIF@POM might be attributed to the charge rearrangement due to the interaction between Co and W. In addition, the low electronegativity of P and the high oxidation state of W in POM could accelerate the rapid OH- transfer and induce the intermediates to adsorb on the Co-O-W bridge bond conformation, which improves the performance of the catalytic OER. This study provides a new idea for the secondary assembly of POM and MOF materials.

ZIF-8/PVA microspheres with an even size were synthesized with the assistance of a simple microfluidic device. The ZIF-8/PVA microdroplets were first generated in a simple co-flow microfluidic device using a PVA aqueous solution dispersed with ZIF-8 nanoparticles as the dispersed phase and fatty acid methyl ester (FAME) as the continuous phase. Subsequently, the ZIF-8/PVA microdroplets were further extracted to form ZIF-8/PVA microspheres. The influence of the type of continuous phase on the sphericity of microspheres was investigated and the effect of ZIF-8 content was studied. Further studies showed that decreasing the extraction rate and using additives of NaCl in the dispersed phase could improve the sphericity of the ZIF-8/PVA microspheres. Finally, the synthesized ZIF-8/PVA microspheres were used to study the loading and release of tetracycline. The results showed that the loading of ZIF-8/PVA microspheres was more than 5 times higher than that of pure PVA microspheres. The drug release time of ZIF-8/PVA microspheres was much longer than that of the PVA microspheres and the release rate was significantly affected by the pH of the environment.

Introduction: The high rate of retear following rotator cuff repair is largely attributed to the absence of a fibrocartilage layer and limited bone regeneration capacity. We aim to evaluate a bioadhesive derived from decellularized porcine annulus fibrosus extracellular matrix, loaded with zeolitic imidazolate framework-8 (ZIF-8), and to promote rotator cuff tendon–bone healing.Methods: Three adhesive formulations were developed: (1) silk fibroin/tannic acid (ST group), (2) ST combined with decellularized porcine annulus fibrosus extracellular matrix (ST/dECM group), and (3) ST/dECM supplemented with ZIF-8 (ST/dECM/ZIF-8 group). Optimal component ratios were determined using lap shear strength testing. The microstructure, Fourier transform infrared (FTIR) spectra, swelling behavior, and degradation properties of the materials were characterized. In vitro studies assessed the adhesives’ effects on cytotoxicity, proliferation, and the chondrogenic and osteogenic differentiation of rat bone marrow-derived mesenchymal stem cells (BMSCs). A rat rotator cuff repair model was used to evaluate in vivo anti-inflammatory effects, fibrocartilage and bone regeneration, and biomechanical performance.Results: All adhesive formulations exhibited comparable tissue adhesion strength and biocompatibility. Both the ST/dECM and ST/dECM/ZIF-8 groups enhanced BMSC chondrogenic differentiation compared to the ST group, with the ST/dECM/ZIF-8 group showing superior osteogenic induction. In vivo, the ST/dECM/ZIF-8 hydrogel effectively reduced interfacial inflammation and promoted fibrocartilage and bone regeneration. Biomechanical testing demonstrated significantly higher ultimate load, tensile stress, and stiffness in all adhesive-treated groups compared to untreated controls.Conclusion: The ST/dECM/ZIF-8 bioadhesive hydrogel promotes fibrocartilage and bone regeneration. These findings highlight its potential as a promising biomaterial-based strategy to enhance tendon-to-bone interface healing following rotator cuff repair.

To address the growing global challenge of water scarcity, developing high-performance reverse osmosis (RO) membranes for desalination and water purification is essential. However, conventional polyamide (PA) thin-film composite (TFC) membranes are limited by the trade-off between permeability and selectivity, as well as limited rejection of small-molecular contaminants. In this study, we report a novel high-permeability thin-film nanocomposite (TFN) RO membrane by tuning the hydrophilicity of a zeolitic imidazolate framework-8 (ZIF-8) interlayer to achieve synergistic enhancement in both desalination and micropollutant removal. Specifically, a ZIF-8 interlayer was in situ grown on a hyperbranched PA-UIO-66-NH 2 support, followed by partial ligand exchange with 5,6-dimethylbenzimidazole (Hdmbim) to reduce its hydrophilicity. This modification facilitated the diffusion of m-phenylenediamine (MPD) monomers, enabling the formation of a highly cross-linked PA selective layer (h-TFN) with angstrom-scale water transport channels. The optimized h-TFN membrane exhibited a water permeability of 5.40 L·m −2 ·h −1 ·bar −1 , 2.94 times that of the control TFC membrane, while maintaining high NaCl rejection (98.35 %). Moreover, it achieved 96.06 ± 0.18 % rejection for micropollutants such as heptyl paraben (HP). These results surpass the permeability–selectivity limitations of existing membranes and demonstrate a promising strategy for the design of advanced RO membranes capable of efficient desalination and micropollutant removal.

Flumequine, a quinolone antibacterial drug, has been widely used in aquiculture. However, excess use of flumequine may lead to antibiotic residues in animals and its rapid determination remains a challenge. In this study, a visual lanthanide metal–organic frame probe of Trp@ZIF-8/Tb3+ was used for the determination of flumequine. The probe was stepwise synthetized by tryptophan (Trp), zeolitic imidazolate framework-8 (ZIF-8), and terbium (III). In the presence of flumequine, the fluorescence of Tb3+ in Trp@ZIF-8/Tb3+ was sensitized. The fluorescence method was fast, requiring only 40 s, the detection range was wide from 0.03 to 1.53 μM, and the detection limit was 0.018 μM. Moreover, the Trp@ZIF-8/Tb3+ probe had good specificity and strong anti-interference ability, which was used for flumequine determination in milk, tap water, and serum. Furthermore, the Trp@ZIF-8/Tb3+ probe provided a method for the rapid determination of flumequine on test strips: The color changed from blue to green with increasing concentration. Hence, the developed Trp@ZIF-8/Tb3+ probe offers an efficient and convenient method for flumequine determination.

In this study, a novel Z-scheme ZnO-AgCl-Ag photocatalyst was prepared by converting the metal-organic framework ZIF-8 to ZnO via a simple pyrolysis method and using a physical wet mixing method. The crystal structure, microstructure, elemental distribution, and photoelectrochemical properties of the catalyst were systematically characterized using various analytical techniques. The characterization results showed that the introduction of AgCl/Ag into ZnO exhibited a higher light absorption capacity as well as a lower transmission resistance. Photocatalytic degradation experiments showed that the ZA-3 sample achieved a 99.97 % degradation rate of 10 mg/L RhB in 24 min, which was 2.3 higher than that of ZIF-8-derived ZnO. In addition, we systematically investigated the effects of initial RhB concentration, solution pH, anion interference, and catalyst recycling cycle on the photocatalytic activity, demonstrating the stability and applicability of the composites under different conditions. In addition, radical trapping experiments were conducted to probe the photocatalytic reaction mechanism, and a Z-scheme charge transfer pathway was confirmed, in which photogenerated electrons were effectively separated and transferred at the Z-scheme heterojunction interface through the conductive channel of Ag nanoparticles as carriers, which significantly improved the photocatalytic activity. In this study, the advantages of MOFS were rationally and effectively utilized to design and prepare Z-scheme photocatalysts with UV–visible response.

In surface-enhanced Raman scattering (SERS) measurements, the creation of “hot spots” and the effective concentration of analytes in these areas are crucial for enhancing detection sensitivity. In this work, a novel composite with highly SERS activity, Ag nanospheres decorated Ag nanostar/ZIF-8 composite (Ag NS/ZIF-8/Ag) was achieved via first coating the Ag nanostars with the metal-organic framework ZIF-8, known for its strong molecular adsorption capabilities, followed by the electrostatic self-assembly of Ag nanospheres. The composites produce numerous hotspots due to the abundant plasmonic nanogaps, including the interstitial space between the Ag nanostar and Ag nanospheres, as well as internanogaps between neighboring Ag nanospheres, resulting in outstanding SERS performance. It was successfully applied for the quantitative and simultaneous detection of diquat and thiram in fruit juice, achieving detection limits of 5.0 × 10 −8 mol/L and 1 × 10 −8 mol/L, respectively, with recovery rates ranging from 86.6 % to 118.4 %. Notably, under UV light exposure, the composite was able to degrade pesticides efficiently within 80 min. Additionally, its reusability was demonstrated by sustaining strong SERS activity over five continuous detection cycles. These results emphasize the capability of Ag NS/ZIF-8/Ag composites for sensitive pesticide detection via SERS.

Rational design of high-performance electrode materials is crucial for enhancing desalination performance of capacitive deionization (CDI). Here, ultrathin nitrogen-doped carbon/Ti 3 C 2 T x -TiN (NC/MX-TiN) heterostructure was developed by pyrolyzing zeolite imidazolate framework-8 (ZIF-8) nanoparticles sandwiched MXene (ZSM), which were formed by assembling ultrafine ZIF-8 nanoparticles with size of 20 nm on both sides of MXene nanosheets. The introduction of ultrasmall ZIF-8 particles allowed for in situ nitridation of the MXene during pyrolysis, forming consecutive TiN layers tightly connected to the internal MXene. The two-dimensional (2D) heterostructure exhibited remarkable properties, including high specific surface area and excellent conductivity. Additionally, the resulting TiN demonstrated exceptional redox capability, which significantly enhanced the performance of CDI and ensured cycling stability. Benefiting from these advantages, the NC/MX-TiN exhibited a maximum adsorption capacity of 45.6 mg g −1 and a steady cycling performance in oxygenated saline water over 50 cycles. This work explores the rational design and construction of MXene-based 2D heterostructure and broadens new horizons for the development of novel CDI electrode materials.

Ethylene glycol (C 2 H 6 O 2 ) is an organic compound widely used in industry and daily life. However, it is toxic to animals and humans and can cause serious health problems when ingested. It is important to explore new sensing materials to achieve effective detection of C 2 H 6 O 2 . In this work, pumpkin shaped aspergillus niger with submicron scale has been cultured, aspergillus niger-derived carbon (ANDC) was prepared by simple carbonization, and then novel ANDC/ZIF-8 composite was prepared using a solvothermal method. ANDC/ZIF-8 exhibits considerable selectivity for C 2 H 6 O 2 at room temperature, and the detection limit was 0.84 ppm and the response/recovery time was 13.9/10.6 s, respectively. Compared to ANDC, the gas sensitive performance of ANDC/ZIF-8 composite is greatly improved. This enhancement should be mainly attributed to the formation of heterogeneous junctions and hydrogen bonding interaction between ZIF-8 and C 2 H 6 O 2 . In this way, the mould with regular shapes produced by biomanufacturing was prepared into biochar, which in turn created a new type of gas sensing material and pioneered the introduction of biomanufacturing into the preparation process of gas sensing materials.

Currently, Zeolitic imidazolate frameworks (ZIFs) face challenges in antibiotic adsorption due to their inherent difficulty in recovery and susceptibility to hydrolysis. To overcome these limitations, herein, Mn-doped ZIF-67 was synthesized via coordination modification and then electrospun with high-mechanical-strength polyvinylidene fluoride (PVDF) to produce Mn-ZIF-67@PVP/PVDF composite nanofiber membranes. Characterization results based on SEM, XRD, and FT-IR analyses demonstrate that the layered nanofiber membrane provides abundant attachment sites for Mn-ZIF-67. Antibiotic adsorption experiments further reveal that the composite membrane exhibits facile recyclability, with Mn-ZIF-67 retaining 80 % of its initial adsorption capacity after five consecutive cycles, while maintaining its crystalline structure and remarkable aqueous stability throughout repeated utilization. The composite membrane achieved maximum adsorption capacities of 583.43 mg/g for tetracycline (TC) and 122.42 mg/g for ciprofloxacin (CIP). The adsorption process followed pseudo-first-order kinetics and Langmuir isotherm models, while thermodynamic analysis revealed a spontaneous and endothermic nature. The adsorption performance showed minimal impact from coexisting ions and pH variations. These superior characteristics of enhanced adsorption performance, exceptional water stability, and convenient recoverability endow the Mn-ZIF-67@PVP/PVDF composite membrane with significant practical advantages over conventional ZIF materials for antibiotic removal applications.

The application of biopolymers in adhesive design holds immense potential for advancing the sustainable manufacturing of high-performance materials. In this study, chitosan (CS), a renewable and biodegradable biopolymer, serves as the structural backbone for developing an innovative organic-inorganic hybrid resin Cu/ZIF-8@CS-MCS@BN. Initially, CS was chemically functionalized via crosslinking with maleic anhydride (MA) to form a maleated chitosan network (CS-MCS), exploiting the biopolymer's abundant amino and hydroxyl groups for covalent bonding. This chitosan-based network was subsequently reinforced with boron nitride nanosheets (BN) and copper-doped ZIF-8 metal-organic frameworks (Cu/ZIF-8), synergistically combining the flame-retardant and mechanical-enhancing properties of inorganic fillers with the organic network of the chitosan matrix. The Cu/ZIF-8@CS-MCS@BN resin was processed into two distinct wood composites: (1) plywood fabricated by hot-pressing poplar veneers with the resin exhibited exceptional interfacial adhesion, achieving a boiling-water-resistant shear strength of 1.01 MPa, which surpasses the requirements of the Chinese national standard GB/T 9846–2015; (2) lightweight aerogels prepared by freeze-drying resin-wood flour mixtures demonstrated outstanding compressive resistance (compressive modulus: 45.23 MPa) and fire safety (limiting oxygen index (LOI) = 42.8 %, UL-94 V-0 rating). This work establishes a green paradigm for fabricating multifunctional wood composites, highlighting the pivotal role of biopolymer engineering in next-generation construction materials.
