Nanopestcides based on metal–organic frameworks (MOFs) have attracted great attention. Highly stable mesoporous metal–organic framework PCN-777 with large pores can accommodate the biologically active insecticide avermectin (AVM) of relatively large molecular dimensions. In this work, PCN-777 nanoparticles were synthesized for the creation of double-gated nanopesticides with sodium lignosulfonate (SL) and chitosan. The double gatekeepers could realize excellent sealing performance to prevent premature leakage of AVM. The double-gated PCN-777 based nanopesticides could achieve the controlled release of AVM in response to pH, laccase, phosphate, and phytic acid (PA), which are related to the physiological environments of pests and crops. The PA-triggered controlled release of loaded cargos in MOF-based delivery systems was reported for the first time. This is the first example of PCN-777 drug/pesticide delivery system and also the first case of controlled-release MOF-based AVM nanopesticides, and the mechanisms of the stimuli-responsive controlled pesticide release were clearly elucidated. The nanopesticides prevented the ultraviolet photolysis of AVM owing to the PCN-777 organic ligands and SL coating. The nanopesticides had high insecticidal efficacy and field control efficacy against the pests Spodoptera litura Fabricius on cabbage, in comparison with traditional pesticide formulations, and the nanopesticides had no influence on plant growth and showed high biosafety toward non-target organisms and human cells. The smart controlled-release nanopesticides show high potential and application prospect in ecological agriculture.

It is important to further enhance the performance of green and efficient non-homogeneous catalysts for advanced oxidation process of Peroxymonosulfate (PMS-AOP) for green treatment of industrial wastewater. In this paper, nitrogen–sulfur co-doped MOFs-derived carbon material (CoSN@C) was prepared by one-pot synthesis followed by carbonization, and its morphological structure was characterized by XRD and SEM. After pyrolysis, the CoSN@C still maintained the dodecahedral morphology and structure of ZIF-67. The synergistic effects of S and N significantly elevated the activation of PMS. The results show that the CoSN@C + PMS system can effectively activate PMS to degrade Rhodamine B (RhB), with a rate constant (1.85 min−1) four times higher than that of the CoN@C + PMS system (0.44 min−1). The optimal catalytic process parameters of material dosage, PMS concentration, temperature, pH, and other parameters were also investigated for the activation of PMS to remove Rhodamine B. The cyclic experiment shows that the CoSN@C has excellent recyclability and the degradation rate of RhB still reached 88.9% after four cycles. Radical capture experiments and EPR tests showed that the CoSN@C + PMS system generated a large amount of SO4·−and ·OH radicals adsorbed on the catalyst surface and a certain amount of singlet oxygen, and the free radical pathway and non-radical pathway worked together to degrade RhB efficiently and rapidly. While non-radical pathway with singlet oxygen as main reactive oxygen species played a key role in the CoN@C + PMS system. This work provides a new idea for the rational design of non-homogeneous catalysts for PMS-AOP system.Keywords:advanced oxidation process;peroxymonosulfate (PMS);non-homogeneous catalyst;MOFs

In the present work, porous Co 3 O 4 was easily prepared via thermal decomposition of metal-organic frameworks (MOFs). TG, FT-IR, XRD, SEM, TEM and N 2 adsorption-desorption were employed for characterizing the synthesized products. Based on cataluminescence (CTL) transduction principle, three MOFs including dodecahedra ZIF-67, nanosheets packed Co-MOF-71, nanoplate Co-BTC, and their corresponding derivatives Co 3 O 4 were used as sensing materials for H 2 S detection, respectively. The dodecahedra ZIF-67-derived dodecahedra Co 3 O 4 with high specific surface and exposed {110} lattice planes presented superior strong CTL property, and had a good linear relation in the concentration range of 3.3–27.5 μg L −1 with the detection limit of 1 μg L −1 (S/N = 3), while the original MOFs displayed no CTL signal. Eighteen common volatile organic compounds (VOCs) were investigated as possible interference, and the results indicated that MOFs-derived porous dodecahedra Co 3 O 4 would be one of excellent sensing material candidates for monitoring H 2 S with a promising application in routine analysis.

Carboxylic acid is one of the most crucial and widely used organic chemicals in daily human life activities. Hence preparation of this important chemical was performed under the application of the highly selective photo-catalysts through oxidation of alcohols to carboxylic acids. Herein, we have designed and disclosed a binary NH 2 -MIL-125(Ti)/ NaBr) catalyst system to realize the effective transformation of alcohols into carboxylic acids under visible light irradiation . Hence, derivatives of benzyl alcohol containing either electron withdrawing and donating groups as well as aliphatic primary alcohols were effectively converted into the corresponding carboxylic acids. Based on our findings, NH 2 -MIL-125(Ti) based photocatalytic system has shown efficient and highly selective activities for oxidation of alcohol especially the in-situ conversion of co-catalyst NaBr into the corresponding free radical can enhance the alcohol oxidation performance of the catalytic system.

Background Glycoproteins are critical in various biological processes and attract lots of attention of researchers. It still remains a challenge to detect glycopeptides by mass spectrometry because of their low abundance with heterogeneity and lability, as well as signal suppression by non-glycopeptides. The boronate affinity-based enrichment is an effective solution for detecting cis -diols-containing compounds including glycopeptides in complex matrices. However, there has not been any report about absolute quantitation of boron in the absorbent materials for glycopeptides, which obstructed the tailored design of boronate affinity materials and deeper understanding of interaction mechanisms. Results This work presents the development of a boronic acid-functionalized magnetic zirconium metal-organic framework (mMOF–AAPBA) with actual boron content for specific capture of glycopeptides. The synthesized nanocomposite could enrich glycopeptides by magnetic solid-phase extraction (MSPE) via the synergistic effect of hydrophilic interaction and boronate affinity. After full characterization including quantitative analysis of boron by laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS), mMOF–AAPBA was applied as MSPE absorbent to capture glycopeptides. Under the optimized conditions, it could enrich 28 glycopeptides both from horseradish peroxidase and immunoglobulin digests, with a limit of detection of 1 fmol μL −1 coupled with matrix-assisted laser desorption/ionization time of flight mass spectrometry. The boronate affinity absorbent also possessed great ability of anti-interference and good reusability. Furthermore, it possessed high performance in enriching glycopeptides in real samples including human saliva and traditional Chinese medicine injections. Significance In the preparation of the boron-containing nanocomposites, there is a special interest that an accurate protocol was established to assay boron based on LA-ICP-MS assisted by home-made matrix reference substances for the first time. These findings highlight the quantitative boron-containing mMOF–AAPBA as a robust affinity material for glycopeptide enrichment in real biological samples, offering potential applications in glycoproteomics and other cis -diols compound related researches.

Immobilization of metal–organic frameworks (MOFs) on multiple substrates is important and challenging in functional materials fields till date. Cotton is a promising carrier material with excellent performance, such as large specific area, mechanical strength and stability, good biocompatibility, and hygroscopicity. In this study, based on the coordination of carboxyl groups and Zr-OH groups, a novel carboxyl cotton chelator-zirconium-based metal–organic framework (CCC@Zr-MOF) was successfully fabricated. The surface of the cotton was first modified by citric acid. Zr-MOF precursor was grown on the carboxyl modified cotton by coordination bond to prepare Zr6O4(OH)4 cluster modified cotton (CCC@Zr6O4(OH)4). Then, Zr-MOF would form and immobilize on CCC@Zr6O4(OH)4 to obtain CCC@Zr-MOF. The CCC@Zr-MOF was characterized by field emission scanning electron microscope equipped with an energy-dispersive X-ray spectrometer, Fourier transform infrared spectroscopy, X-ray diffraction, X-ray photoelectron spectra, and Brunauer–Emmett–Teller. The successful formation of Zr-MOF on the surface of cotton has been demonstrated. CCC@Zr-MOF was packed in the pipette tip for the solid-phase extraction to evaluate its adsorption property for phenolic acid compounds from complex matrix sample. The results showed that CCC@Zr-MOF performed an efficient adsorption and selectivity.

Recently, metal–organic frameworks (MOFs), which are porous inorganic–organic hybrid materials consisting of metal ions (clusters or secondary building units) and organic ligands through coordination bonds, have attracted wide attention because of their high surface area, huge ordered porosity, uniform structural cavities, and excellent thermal/chemical stability. In this work, durian shell biomass carbon fiber and Fe3O4functionalized metal–organic framework composite material (durian shell fiber-Fe3O4-MOF, DFM) was synthesized and employed for the adsorption removal of methylene blue (MB) from wastewater. The morphology, structure, and chemical elements of the DFM material were characterized by scanning electron microscope (SEM), X-ray diffraction (XRD), transmission electron microscope (TEM), and X-ray photoelectron spectroscope (XPS) techniques. Adsorption conditions such as pH, adsorption time, and temperature were optimized. The adsorption isotherm and kinetics results show that the adsorption process of DFM material to MB is more in line with the Freundlich model and pseudo-second-order kinetic model. Using these models, the maximum adsorption capacity of 53.31 mg/g was obtained by calculation. In addition, DFM material could be easily reused through an external magnet and the removal rate of MB was still 80% after five adsorption cycles. The obtained results show that DFM composite material, as an economical, environmentally friendly, recyclable new adsorbent, can simply and effectively remove MB from wastewater.Keywords:biomass fibers;durian shell;magnetic composite;adsorption

Conventional electromagnetic wave (EMW) absorbing materials often suffer from poor stability in humid and corrosive environments, limiting their real-world applications. In this work, carbon-based composites derived from Ti-Ni bimetallic metal-organic frameworks (MOFs) were synthesized via pyrolysis and investigated as dual-function materials for EMW absorption and corrosion protection. The composites exhibit excellent impedance matching and strong attenuation capability due to the synergistic interaction between the metal oxides and the carbon matrix. A minimum reflection loss of −40 dB and an effective absorption bandwidth of 4.61 GHz were achieved at an optimized thickness of 4.1 mm. Furthermore, upon incorporation into an epoxy resin coating, the composite displayed outstanding corrosion resistance. After immersion in a 3.5 wt% NaCl solution for 7 days, good stability was still maintained. This study presents a promising strategy for designing multifunctional materials with integrated EMW absorption and corrosion resistance, offering broad application potential in marine, aerospace, and communication sectors.

Graphical MOFs-templated MgO/ZrO 2 enable highly selective glucose-to-fructose conversion. Structural confinement suppresses MgO agglomeration and tunes basicity, achieving 38.4% yield with 90.9% selectivity. High-selectivity glucose isomerization to fructose is essential for the biorefinery industry and fructose syrup production. In this work, a catalyst with tailored basicity was synthesized via the calcination of a MOFs (metal-organic frameworks)-based composite and employed as a chemo-catalyst for glucose isomerization, achieving high fructose selectivity. Characterization results confirmed that the synthesized catalyst was a composite consisting of and MgO, with MgO highly dispersed within the channels of . The MOFs templating effect restricted particle size and minimized agglomeration of MgO particles, enhancing the interaction between MgO and . This strong interaction effectively modulated the basicity of the catalyst, resulting in the predominance of weak basic sites. As a result, the catalyst demonstrated superior performance in glucose isomerization, achieving a 38.4% fructose yield with 90.9% selectivity at a 10 wt% glucose concentration, outperforming catalysts prepared by conventional methods. However, leaching remains a challenge. This work presents a novel approach for synthesizing highly dispersed mixed oxides and provides an effective catalyst for glucose isomerization.

Photodynamic therapy (PDT) is widely used for the treatment of hypertrophic scars in clinical practice. However, the low transdermal delivery of photosensitizers in scar tissue and protective autophagy induced by Photodynamic therapy greatly reduces the therapeutic efficiency. Therefore, it is necessary to deal with these difficulties for overcoming obstacles in Photodynamic therapy treatment. In this study, a photosensitizer with photocatalytic performance was designed and synthesized using innovative MOFs (metal-organic frameworks). Additionally, the MOFs, together with an autophagy inhibitor chloroquine (CQ), was loaded in a high mechanical strength microneedle patch (MNP) for transdermal delivery. With these functionalized MNP, photosensitizers and chloroquine were delivered deep inside hypertrophic scars. Inhibition of autophagy increases the levels of reactive oxygen species (ROS) under high-intensity visible-light irradiation. Multiprong approaches have been used to remove obstacles in Photodynamic therapy and successfully enhance its anti-scarring effect. In vitro experiments indicated that the combined treatment increased the toxicity of hypertrophic scar fibroblasts (HSFs), downregulated the level of collagen type I expression as well as transforming growth factor-β1 (TGF-β1)expression, decreased the autophagy marker protein LC3II/I ratio, increased the expression of P62. In vivo experiments showed that the MNP had good puncture performance, and significant therapeutic effects were observed in the rabbit ear scar model. These results indicate that functionalized MNP has high potential clinical value.

A “double immobilized” superhydrophobic and lubricated slippery surface was prepared by simultaneously immobilizing lubricating oil and bactericide molecules. The coordination function of metal organic frameworks (MOFs) was utilized to immobilize trimesic acid, a fungicide, as a ligand of the MOF by the cathodic electrodeposition technique. Aminated silicone oil was used as a lubricating oil and was immobilized to the superhydrophobic MOF film by the curing reaction with isocyanates. This technique is a facile strategy to conductive substrates for fabricating superhydrophobic and lubricated slippery surfaces with satisfactory antibacterial and antifouling properties.

Advances in membrane technologies are significant for mitigating global climate change because of their low cost and easy operation. Although mixed-matrix membranes (MMMs) obtained via the combination of metal-organic frameworks (MOFs) and a polymer matrix are promising for energy-efficient gas separation, the achievement of a desirable match between polymers and MOFs for the development of advanced MMMs is challenging, especially when emerging highly permeable materials such as polymers of intrinsic microporosity (PIMs) are deployed. Here, we report a molecular soldering strategy featuring multifunctional polyphenols in tailored polymer chains, well-designed hollow MOF structures, and defect-free interfaces. The exceptional adhesion nature of polyphenols results in dense packing and visible stiffness of PIM-1 chains with strengthened selectivity. The architecture of the hollow MOFs leads to free mass transfer and substantially improves permeability. These structural advantages act synergistically to break the permeability-selectivity trade-off limit in MMMs and surpass the conventional upper bound. This polyphenol molecular soldering method has been validated for various polymers, providing a universal pathway to prepare advanced MMMs with desirable performance for diverse applications beyond carbon capture.
