Since ammonium perchlorate (AP) thermal decomposition catalysis is a typical heterogeneous catalytic process, developing catalysts with optimized interfacial properties has become an urgent priority. Catalysts featuring hierarchically porous structures demonstrate significant advantages in heterogeneous catalysis due to their abundant accessible active sites. In this study, a wrinkled hierarchically porous structure cerium-based metal–organic framework material (WHP-UiO-66-Ce) was synthesized by the soft template method, and its interaction with AP enabled efficient catalysis of AP decomposition. The results show that under the catalysis of WHP-UiO-66-Ce, the high-temperature decomposition peak of AP is reduced from 427.2 to 361.5 °C. Meanwhile, WHP-UiO-66-Ce significantly enhances the rate of decomposition of AP, which is attributed to its unique structure. Furthermore, concerns about the issue of the agglomeration of catalysts have significantly diminished. This strategy provides an idea for designing efficient catalysts for AP thermal decomposition.

A Fe/Co-doped zeolitic imidazolate framework-8 (ZIF-8) is synthesized in situ on porous carbonized wood, and high-performance composite electrodes are subsequently prepared through heat treatment. The simultaneous doping of Fe and Co can synergistically modulate the microstructures, nanoporous architectures, and hydrophilic properties of the carbon materials derived from metal-organic frameworks (MOFs), thereby enhancing their specific capacitance and energy density. Furthermore, the superior capacitive performance of Fe/Co-doped MOF-derived carbon on porous carbonized wood (Fe-Co/MC@PCW) is predicted through first-principles density functional theory calculations, which are based on the detailed analysis of band structure and surface adsorption characteristics. The composite electrode demonstrated a specific capacitance of 342 F g −1 (6.84 F cm −2 ) at 5 mA cm −2 . Correspondingly, a symmetric supercapacitor fabricated with this electrode achieved a specific capacitance of 141 F g −1 (2.82 F cm −2 ) under identical conditions, yielding an energy density of 19.58 Wh kg −1 and a power density of 125 W kg −1 . Notably, the electrode maintains exceptional capacitance retention, demonstrating only a minor reduction to 96 % after 15,000 cycles, even at 30 mA cm −2 . These results underscore the potential of integrating MOFs with wood-based carbon electrodes for the development of advanced energy storage systems.

Metal organic frameworks (MOFs), with their ultrahigh surface area and tunable pore architectures, have emerged as transformative materials for pesticide residue detection. Herein, we engineered a multifunctional magnetic-fluorescent nanoprobe (Fe 3 O 4 @RhB@ZIF90@AChE) for organophosphorus (OPs) and carbamate (CMs) pesticides detection via a one-pot synthesis strategy. Leveraging the pore confinement effect of ZIF90, the platform enhances enzyme–substrate affinity while enabling a cascade signal transduction to produce quantifiable fluorescence inversely proportional to pesticide concentrations. The sensor achieved ultralow detection limits for omethoate (0.015 mg/L), carbofuran (0.020 mg/L), dichlorvos (0.019 mg/L), and trichlorfon (0.021 mg/L) across a broad linear range (0.01–2 mg/L), with exceptional reproducibility (RSD < 3.74 %) and accuracy (spiked recoveries: 97.7–4.5 % in fruits/vegetables). Integrated magnetic separation streamlined detection to 20 min, outperforming conventional methods in speed and operational simplicity. This work pioneers a MOF-based “capture-release-signal” paradigm, offering a field-deployable solution for rapid, high-throughput pesticide screening in agricultural and food safety monitoring.

Traditional DNA purification methods face limitations in efficiency and complexity, particularly for food authenticity verification. To address this, we developed novel magnetic nanocomposites by integrating polydopamine-coated Fe 3 O 4 nanoparticles (Fe 3 O 4 @PDA) with zirconium-based metal-organic frameworks (Zr-MOFs) functionalized via varying organic ligands (terephthalic acid, 2-aminoterephthalic acid, and 1,2,4-benzenetricarboxylic acid). The resulting materials—MUIO-66, MUIO-66-NH₂, and MUIO-66-COOH—were characterized for structure, magnetism, and DNA adsorption performance. MUIO-66-COOH exhibited superior efficiency, achieving >80 % DNA recovery from camel meat under optimized conditions (25 °C, 10 min), outperforming commercial kits. Adsorption kinetics and isotherms revealed a multilayer process (Freundlich model) governed by pseudo-second-order kinetics, driven by "salt-bridge" interactions between DNA phosphate groups and surface carboxyl moieties. The method demonstrated high precision (RSD = 2.75 %), reproducibility, and reusability (>81 % efficiency after 5 cycles). This work establishes a rapid, ligand-tunable magnetic solid-phase extraction (MSPE) platform for high-quality DNA extraction, advancing biosensing applications in food authenticity.

The research on the reuse of resources is crucial for achieving high-value utilization of traditional Chinese medicine (TCM). In this study, licorice residues were selected to extract fibers by alkaline hydrogen peroxide oxidation because of their high cellulose content and widespread use. The cellulose, hemicellulose and lignin content of obtained fibers were found to be 55 %, 8.2 % and 18.8 %, respectively. Immobilizing MOF-808 onto licorice residue fibers yields a composite material exhibiting enhanced adsorption capabilities. The synthesized material was employed to adsorb ketoprofen, naproxen and diclofenac sodium. The characterization results confirmed the successful modification. Adsorption performance experiments indicate that the adsorption behavior follows pseudo-second-order kinetic models and Langmuir isotherm. The adsorption is a process of rapid adsorption and slow equilibrium, showing satisfactory adsorption capacity. X-ray photoelectron spectroscopy and density functional theory calculation revealed that the sustained adsorption attributed to the synergy of π-π stacking, hydrogen bonding and coordination interaction. This study emphasizes the potential for reusing licorice residues and paves the way for the treatment of TCM residue after extracting active ingredients.

Ag-MOF nanoparticles were successfully synthesized using a convenient and mild liquid-phase route, employing AgNO 3 , imidazole, and trimesic acid (H 3 BTC) as a unique multifunctional organic ligand, which, unlike conventional Ag-MOF systems based on simple imidazole, enables the formation of a more stable and highly coordinated framework structure, thereby facilitating uniform particle distribution and improved functionality. This study investigated its antibacterial mechanism and effectiveness when the nanoparticles were integrated into acrylic coatings on AA2024 aluminum alloy substrates. The synthesized Ag-MOF particles demonstrated significant antibacterial activity, which is attributed to the sustained release of Ag + ions and its stable dispersion within the coating matrix. The reduction in E. coli and S. aureus populations was observed to be 95.9 % and 87.2 %, respectively. Benefiting from both the physical barrier effect and the controlled delivery of corrosion inhibitors, the coating exhibits improved durability against corrosion. Additionally, a bifunctional composite coating, featuring a cerium-doped sol-gel application as a bottom layer, was prepared to further improve antibacterial and anticorrosion properties. Electrochemical tests confirm that the composite coating shows the higher impedance modulus and the smaller corrosion current density across the low-frequency domain than neat coating, which was the contribution of the combined action of the inhibitor and the coating's barrier properties. According to the electrochemical impedance after 7 days immersion, the composite coating showed superior corrosion resistance comparing to the neat acrylic coating during immersion of seven days.

Endogenous phosphorus (P) release is one of the key factors leading to eutrophication of water body. Phosphorus in sediments is difficult to be removed or recovered due to its chemical stability and complex morphology. Meanwhile, lanthanide metal organic framework (La-MOF) shows high efficiency in phosphate adsorption, but faces challenges in solid-liquid separation due to its powder form. In this study, the phosphorus solubilizing bacteria (PSB), Leclercia adecarboxylata L1–5, was used to transform some fractions of insoluble phosphorus in sediment into soluble phosphorus, and the La-MOF/Polypropylene (La-MOF/PP) fabric was innovatively prepared for phosphate adsorption. Solvothermal method was used for the preparation of La-MOF/PP fabric and the optimum synthesis time was 12 h. The best effect of phosphate removal was achieved when the La-MOF/PP fabric dosage was 1 g/L and the pH was 7. The regeneration efficiency of the material remained stable after five cycles of adsorption and desorption. Furthermore, the simulation results showed that PSB can release dissolved phosphate up to 5.40 mg P/L from sediment. After coupling with the La-MOF/PP fabric, the concentration of phosphate in the overlying water was significantly reduced to 0.38 mg P/L, which was much lower than that in the CK group (2.4 mg P/L). This study demonstrated that the coupled system of PSB and La-MOF/PP fabric could effectively reduce the sediment phosphate content, mitigate the negative impact of possible release of sediment phosphorus and degradation of the overlying water quality. It provided a promising technique for in-situ remediation of sediment phosphate.

Cancer treatment techniques often struggle to simultaneously address the issues of significant impact from cancer heterogeneity, poor resistance to drugs, and non-selective drug toxicity. Therefore, cancer treatment strategies based on nanoplatforms with multiple responsive properties have attracted wide attention due to their broad applicability and minimal side effects on normal cells. Herein, we constructed a nano iron-based metal–organic framework loading Pt and coated with polydopamine (Fe-MOF-NH 2 @Pt@PDA) using the solvothermal method for multimodal cancer therapy. The Pt and Fe could leverage the unique weak acidity and overexpression of hydrogen peroxide in the tumor cell to generate reactive oxygen species (ROS) for chemodynamic therapy (CDT). Additionally, Pt and Fe gave its peroxidase-like activity to produce oxygen, improving the hypoxic environment in the tumor microenvironment. Due to Pt, Fe-MOF-NH 2 @Pt@PDA achieved excellent sonodynamic therapy (SDT) under ultrasound (US) stimulation. Under US, more ROS were generated, enhancing the anticancer effect of CDT. Moreover, Fe-MOF-NH 2 @Pt@PDA produced an excellent photothermal effect under 808 nm near-infrared (NIR) irradiation for photothermal therapy (PTT). Furthermore, Fe-MOF-NH 2 @Pt@PDA exhibited good biocompatibility. Taken together, the nano Fe-MOF-NH 2 @Pt@PDA with synergistic CDT, SDT, and PTT combined treatment was a promising biomaterial for non-invasive clinical cancer therapy.

Two-dimensional conductive metal–organic frameworks (2D c-MOFs) hold great promise for electrochemical applications due to their π-conjugated structures and high conductivity, but their application in electrochemiluminescence (ECL) sensing remains largely unexplored. In this study, we synthesized 2D c-MOF Cu3(benzenehexathiol) nanosheets (CuBHT NSs) with lateral dimensions of 2–10 μm and a thickness of 24 nm and immobilized them on indium tin oxide (ITO) electrodes. This platform facilitated the first study of luminol’s cathodic ECL behavior. CuBHT NSs exhibited exceptional oxygen reduction reaction (ORR) catalytic activity, significantly enhancing the generation of reactive oxygen species (ROS) and thereby increasing the luminol’s cathodic ECL response. Mechanistic studies confirmed that unsaturated Cu sites in CuBHT play a crucial role, as Uric acid (UA) can bind to unsaturated Cu sites, inhibiting ROS production. This outcome enabled a highly sensitive and selective ECL sensor for UA with a wide linear range (10 nM–0.1 mM) and a low detection limit (3.5 nM, S/N = 3). The sensor was successfully applied to detect UA in serum samples.

Metal-organic frameworks (MOFs) are regarded as potential candidate materials with great application prospects in the field of gas sensing. In this study, MOF derivatives were anchored onto MXene sheets through self-assembly technology to prepare a heterojunction material ZnO/Ti 3 C 2 T x MXene with high specific surface area, achieving ultrafast dual gas sensing behavior for H 2 /NO 2 . At a low temperature of 80°C, the ZnO/ Ti 3 C 2 T x MXene heterojunction sensor exhibited an ultrafast response (23.17%) to 500 ppb H 2 within 3.2 s. After a moderate temperature increase to 180°C, it also demonstrated significant sensing performance (46.3%) to 500 ppb NO 2 within 4 s. The electronic interaction mechanism of ZnO/ Ti 3 C 2 T x MXene heterostructures in H 2 and NO 2 detection was revealed through density functional theory calculations and in-situ Raman spectroscopy, clarifying the influence of interfacial charge transfer on sensing performance. Heterogeneous structures achieve the regulation of gas adsorption-induced electron rearrangement and carrier modulation by constructing interface charge-regulating channels, significantly enhancing the response rate, selectivity and reversibility in the detection of H 2 and NO 2 , thereby enabling highly sensitive and trace detection of the two gases.

Repairing large bone defects effectively requires concurrent osteogenesis and angiogenesis, a significant challenge for conventional biomaterials often limited by suboptimal structural design and an inability to provide spatiotemporally controlled bioactive cues. Here, we report a novel chemophysical dual-responsive system rationally designed to address this osteogenic-angiogenic coupling challenge. This system integrates a structurally engineered bimetallic FeCu-metal-organic framework (FeCu-MOF) within a poly(lactic acid)/hydroxyapatite (PLA/HA) scaffold. The engineered FeCu-MOF architecture enables the programmed and sustained co-release of Fe 3+ and Cu 2+ ions, providing tailored chemical signals. Synergistic pulsed electromagnetic field (PEMF) stimulation was introduced as a physical cue to further enhance the scaffold's bioactivity. The composite scaffolds, featuring interconnected hierarchical porosity and enhanced hydrophilicity due to FeCu-MOF incorporation, demonstrated distinct Fe 3+ /Cu 2+ release profiles. In vitro , these scaffolds exhibited excellent biocompatibility and significantly promoted bone marrow mesenchymal stem cells (BMSCs) proliferation and osteogenic differentiation. Notably, this structure-derived dual-ion release also indicated pro-angiogenic potential. Crucially, daily PEMF treatment synergistically amplified these cellular responses. In vivo evaluation in a rat cranial defect model confirmed the system's efficacy. While FeCu-MOF/PLA/HA scaffolds alone enhanced bone regeneration, their combination with PEMF yielded the most robust outcomes, characterized by markedly superior vascularized bone formation. Comprehensive analysis, including micro-CT, histology, and immunohistochemistry, confirmed these findings by demonstrating improved bone volume, density, and architecture, mature integrated tissue, and enhanced coupled expression of CD31 and osteogenic markers. In summary, the study validates a powerful synergistic strategy for enhanced bone regeneration. This strategy, integrating programmable, structure-derived bimetallic ion release with PEMF stimulation, successfully achieved synergistic angiogenic-osteogenic coupling, offering a promising approach for complex defect scenarios.

The detection of biomolecules using MOF-based nanozymes is a widely adopted strategy due to their abundant active sites and inherent enzymatic properties. In this study, we have synthesized three types of cerium metal-organic frameworks (Ce-MOFs) with oxidase (OXD)-like activity using a facile one-pot solvothermal method, simply by adjusting the concentrations of the raw ingredients, for the monitoring of biomolecules. The synthesized Ce-MOFs exhibit strong stability, a higher specific surface area, and more active sites, attributed to their MOF structure. These Ce-MOFs, with their excellent OXD-like activity, demonstrate satisfactory analytical performance in the quantitative determination of glutathione (GSH), showing a linear relationship within the range of 4.7 to 32.5 μM and detection limits as low as 42.76 nM. Furthermore, this colorimetric biosensor was successfully applied to monitor the content of GSH in the gingival crevicular fluid of patients with periodontitis. This paper extends the application of Ce-MOFs in bioassays and provides new insights into the application of OXD-like nanozymes in bioassays.
