Developing solid-state polymer electrolytes (SPEs) with fast Li + transport and stable electrode interfaces is essential for high-performance lithium metal batteries. Herein, a protonated amino-functionalized metal-organic framework (pro-UiO66) is incorporated into a PEO-LiTFSI matrix to construct composite SPEs. Protonation introduces abundant TFSI − adsorption sites(-NH 3 + ), while the three-dimensional porous framework disrupts PEO crystallinity and provides angstrom-scale pathways for Li + migration. Various characterization confirms that pro-UiO66 maintains crystallinity and uniform dispersion in the polymer matrix. The optimized electrolyte containing 10 wt% pro-UiO66 exhibits reduced crystallinity (29.57%), a high Li + transference number (0.55), and an ionic conductivity of 4.65 × 10 −4 S cm −1 at 60 °C, together with an electrochemical stability window of 5.3 V. Li||Li symmetric cells cycle stably for over 3200 h, while LFP||Li cells deliver 142 mAh g −1 with 92.2% capacity retention after 300 cycles. Mechanistic analysis indicates that the synergistic effects of the porous framework and -NH 3 + functional groups promote LiTFSI dissociation, regulate Li + deposition, and enable the formation of a stable solid electrolyte interphase, thereby suppressing dendrite growth. This work provides insight into protonation-engineered MOFs fillers for designing SPEs toward safe and high-performance solid-state lithium metal batteries.

Triple-negative breast cancer (TNBC) displays pronounced molecular heterogeneity and metastatic propensity, which correlates with its poor clinical prognosis. Crucially, radiotherapy (RT) resistance serves as a pivotal contributor to treatment failure and disease advancement in TNBC. To address this challenge, we developed BWFP, which is achieved by loading WZB117 and FIN56 onto bismuth-based metal organic framework with radiosensitization effect and surface modifying pH-responsive DSPE-PEOz. Under the acidic tumor microenvironment, BWFP controllably releases its payload: WZB117 suppresses glucose uptake through GLUT1 downregulation, thereby limiting NADPH production and inducing cystine accumulation alongside cysteine depletion, which concurrently triggers disulfidptosis and relieves ferroptosis resistance. Meanwhile, the released ferroptosis inducer FIN56 further amplifies ferroptosis by degrading GPX4. In addition to this, BWFP enhances RT efficacy through radiosensitization effects, consequently intensifying DNA damage. In a word, BWFP demonstrates robust anti-tumor activity in TNBC models by concomitantly inducing disulfidptosis and ferroptosis with synergized radiosensitization. Graphical abstract

By pyrolyzing Cu‐based MOFs, a Cu 0 /Cu +1 /C/N catalyst with a porous carbon layer coating was synthesized. The combination of the Cu ion‐rich active sites derived from MOFs and the Raman signal enhancement associated with Cu nanostructures and charge–transfer interactions, which contributes to the SERS effect, was utilized for in situ investigation of the electrochemical CO 2 reduction reaction (CO 2 RR) process. This study focuses on the catalytic performance and reaction mechanisms of Cu‐MOF‐derived materials in the electrocatalytic CO 2 reduction reaction, using in situ Raman and SERS techniques for real‐time monitoring and characterization. The results indicate that Cu‐MOF‐derived materials significantly enhance the selectivity toward C 2 products by tuning the valence state distribution of copper (Cu(I)/Cu(0)) and the structure of active sites. Moreover, the porous carbon‐coated Cu elements exhibit stable catalytic performance during the electrocatalytic process (inhibiting hydrogen evolution reaction and stabilizing the valence state of Cu ions). In addition, in situ spectroscopy reveals the dynamic evolution of key intermediates (such as *CO and *CHO) and the ion adsorption process on the catalyst surface, providing crucial insights into the catalytic behavior of Cu‐MOF‐derived materials. We synthesized a Cu 0 /Cu + /C/N catalyst with a porous carbon coating by pyrolyzing Cu‐based MOFs. The abundant Cu‐ion active sites inherited from the MOF structure and the electromagnetic‐field–enhanced charge‐transfer effect of the carbon matrix enable strong SERS activity for in situ monitoring of the CO 2 reduction reaction (CO 2 RR). Using in situ Raman and SERS, we investigated the catalytic performance and reaction mechanism of Cu‐MOF‐derived materials. The results show that regulating the Cu 0 /Cu + valence distribution and tuning the active‐site structure significantly enhance C 2 product selectivity. The porous carbon layer further stabilizes Cu species and suppresses the competing hydrogen evolution reaction, ensuring durable catalytic performance. In situ spectroscopy reveals the dynamic evolution of key intermediates (*CO, *CHO) and ion‐adsorption behavior on the catalyst surface, providing critical mechanistic insights. This work highlights the potential of MOF‐derived Cu catalysts for efficient CO 2 RR and offers guidance for designing advanced electrocatalysts.

A key challenge in lightweight broadband electromagnetic
wave (EMW)
absorption is balancing strong attenuation, good impedance matching,
and structural integrity─excessive conductivity enhances dielectric
loss but often causes severe surface reflection that blocks wave penetration.
Herein, a 3D x CuFe/GPC heterostructure was constructed
by anchoring bimetallic CuFe-MOF derivatives onto a G/BPNS/CNT hybrid
conductive framework, where G, P, and C represent graphite, black
phosphorus nanosheets, and carbon nanotubes, respectively. CuFe-MOF
derivatives provide magnetic-dielectric loss, BPNS introduce phosphorus-related
polarization sites, and graphite/CNT meshes build long-range conductive
pathways, with CNTs acting as one-dimensional bridges. This coordinated
design enables the optimized 0.1CuFe/GPC composite to achieve an RL min of −46.3 dB at 2.1 mm and an EAB
of 4.03 GHz at 1.3 mm. RCS simulations based on a PEC plate model
show an RCS reduction exceeding 30 dB. Beyond EMW absorption, 0.1CuFe/GPC
serves as a microwave-to-thermal transducer for rapid expandable polystyrene
(ePS) foaming, producing lightweight multifunctional foams with robust
mechanical integrity. This work provides a practical route toward
integrated electromagnetic protection and lightweight structural-functional
materials.

A magnetic Zr-MOF@Fe 3 O 4 material for rapid phosphorus removal was developed. • A maximum phosphate uptake of 141.0 mg P g −1 was achieved. • Phosphate adsorption mainly involved ion exchange and inner-sphere coordination. • DFT calculation elucidated the orbital hybridization between Zr and O atoms. Environmental remediation of phosphorus-containing wastewater is crucial for ecological protection and sustainable resource development. However, existing adsorbents generally suffer from slow phosphate uptake kinetics, limited adsorption capacity and difficult solid-liquid separation. Here, a magnetic Fe 3 O 4 -modified zirconium-based metal–organic framework (Zr–MOF@Fe 3 O 4 ) was synthesized via a simplified hydrothermal process for highly selective phosphate adsorption. Outperforming most reported adsorbents, Zr–MOF@Fe 3 O 4 –1.0 with the porous framework and abundant active sites significantly enhanced phosphate adsorption kinetics, achieving an adsorption rate of 173.3 mg P g –1 h −1 within 0.5 h and a maximum adsorption capacity of 141.0 mg g −1 . Experimental results and density functional theory calculations indicated that the efficient phosphate capture was primarily attributed to synergistic effects of electrostatic adsorption, ion exchange with surface hydroxyl groups, and inner-sphere complexation via Zr–O–P bonds. Excellent anti-anion interference performance, coupled with robust cycling stability and rapid magnetic separation, collectively highlight the application potential of Zr–MOF@Fe 3 O 4 for phosphate removal from complex wastewaters.

Carbon fabric (CF)-reinforced polymer composites show great potential in wet friction applications, but their performance is severely limited by poor interfacial adhesion and susceptibility to abrasive wear. Herein, we propose a “rigid-flexible” hierarchical interface strategy utilizing a conformal defect-filling carboxymethyl cellulose (CMC) layer and an in-situ grown rigid UiO66-NH 2 octahedral array to enhance the mechanical and tribological properties of CF/phenolic composites. The CMC/UiO66-NH2 hierarchical modification reduced surface defects and increased the apparent single-fiber tensile strength by 89.3%. Meanwhile, the UiO66-NH 2 array increased the surface roughness and promoted mechanical interlocking with the resin matrix. The combined CMC/UiO66-NH 2 interface improved interfacial load transfer and reduced premature debonding, leading to a 75.1% increase in tensile strength. Furthermore, under alternating friction shear, the hierarchical interface promotes the formation of a protective tribofilm, promoting the in-situ formation of a continuous solid tribofilm. This transitions the wear mechanism from severe abrasive wear to mild sliding wear, resulting in an 81.1% reduction in the specific wear rate. This study provides an interfacial design strategy for designing high-load-bearing and highly durable fabric composites for demanding tribological applications.

An MOF-based molecularly imprinted nanozyme was designed and prepared. • The nanozyme was acted as ratiometric sensor for fluorescence detection of carbaryl. • The sensor possessed the highly selectivity and sensitivity for carbaryl recognition. • The detection mechanism of MOF based nanozyme for carbaryl was investigated. Metal-organic framework (MOF) nanozymes are widely utilized in environmental pollutant detection, but their practical application is often restricted by a lack of intrinsic selectivity. To address this challenge, we developed a molecularly imprinted polymer coated Fe-MOF nanozyme (Fe-MOF@MIP) via a metal coordination and hydrogen-bonding assembly strategy. Fe-MOF@MIP integrates the peroxidase activity of Fe-MOF core with the specific recognition capability of the carbaryl-imprinted shell. And the binding of carbaryl to the specific imprinted cavities sterically blocks the surface channels, preventing the generation of reactive oxygen species and thereby modulating the fluorescence signal. Based on this inhibition mechanism, a ratiometric fluorescence sensor was constructed for sensitive detection of carbaryl with a detection limit of 0.039 μM, accompanying with the fluorescence color changing from yellow to blue under a UV lamp. More importantly, Fe-MOF@MIP exhibited high selectivity and anti-interference ability for carbaryl detection. The sensor was successfully applied to the analysis of real water and fruit samples, demonstrating their robustness. This study provides a cost-effective and simple strategy to overcome the selectivity bottleneck of nanozymes, offering a promising platform for carbaryl monitoring.

Metal-deficient Zr nodes are constructed in UiO-66-NH 2 by vacuum treatment. • Zr-node microenvironment regulation enhances charge separation and O 2 activation. • UN 200/28 achieves 272.9 μmol g −1 h −1 H 2 O 2 production in pure water. • UN 200/28 delivers a 20-fold activity increase and 6.36% AQY at 420 nm. • H 2 O 2 formation follows an ORR-dominated pathway with secondary WOR contribution. Photocatalytic H 2 O 2 production from pure water and O 2 offers a sustainable route for green oxidant synthesis, yet its efficiency is limited by insufficient O 2 activation, sluggish charge separation, and poorly defined active sites. Herein, a metal-defect-engineered UiO-66-NH 2 photocatalyst is constructed through high-temperature vacuum treatment to regulate the Zr-node coordination microenvironment. The optimized UN 200/28 preserves the UiO-66-NH 2 crystalline framework and octahedral morphology, while a 7.8% decrease in Zr content is confirmed by ICP, STEM, FTIR, XPS and EPR, thereby indicating the formation of metal-deficient Zr nodes and the reconstruction of the local Zr O coordination microenvironment. These defect-induced structural modifications broaden visible-light absorption, narrow the band gap from 2.88 to 2.57 eV, and promote photogenerated charge separation and transfer. UN 200/28 exhibits markedly enhanced photocatalytic H 2 O 2 production in pure water under O 2 , achieving an H 2 O 2 formation rate of 272.9 μmol g −1 h −1 , a 20-fold improvement over pristine UiO-66-NH 2 , and an apparent quantum yield of 6.36% at 420 nm. The O 2 reduction and water oxidation processes account for approximately 63.2% and 36.8% of the total H 2 O 2 formation, respectively. This work demonstrates that cluster-level regulation of the Zr-node coordination microenvironment is an effective strategy for enhancing photocatalytic H 2 O 2 production in pure water.

A novel core–shell structured NH 2 -MIL-88(Fe)@TFPT-Tt-COF composite was successfully constructed via an in situ growth strategy, enabling intimate interfacial bonding and synergistic effects between the MOF core and the COF shell. • The composite exhibits dramatically enhanced fluorescence compared to the individual MOF or COF, and acts as a “turn-off” sensor for nitrofurantoin (NFT) with an ultralow detection limit of 0.18 μg·mL −1 based on the inner filter effect. • The sensing platform features rapid response (equilibrium within 1 min), excellent selectivity against common metal ions and antibiotics, and good applicability in real samples with recoveries of 84.3%–107.6% in soil and lake water. • Offers a new strategy for applying MOF@COF heterostructures to the on-site, rapid, and sensitive detection of trace antibiotic residues in complex environmental matrices. A core-shell structured NH 2 -MIL-88(Fe)@TFPT-Tt-COF composite was successfully constructed via an in situ growth strategy, using NH 2 -MIL-88(Fe) as the core and TFPT-Tt-COF as the shell. The structure, morphology, and thermal stability of the composite were systematically characterized by Fourier transform infrared spectroscopy, powder X-ray diffraction, scanning/transmission electron microscopy, thermogravimetric analysis, and nitrogen adsorption–desorption measurements. The results confirmed the intimate interfacial bonding between the MOF core and the COF shell. Compared with the individual components, the composite displayed significantly enhanced fluorescence intensity. A fluorescent sensing platform based on this composite was developed, which enabled highly sensitive and selective detection of nitrofurantoin (NFT). Preliminary mechanistic studies revealed that the quenching effect mainly originated from a photoinduced electron transfer (PET) mechanism. The proposed method was applied to the spike recovery analysis of NFT in real samples such as soil and lake water, yielding recoveries ranging from 84.3% to 107.6%, with a limit of detection as low as 0.18 μg·mL −1 , demonstrating that the sensor possesses satisfactory accuracy and practicality in complex environmental matrices. This work provides a new strategy for the application of MOF/COF composites in the rapid detection of antibiotic residues in the environment.

Systematic comparison of ligand functionalization effects on surface properties and demulsification using UiO-66. • Hydrophobic (UiO-66-4F) and electrostatic (UiO-66-NH 2 ) mechanisms both achieve ∼80% demulsification efficiency. • The hydrophobic mechanism is more versatile across different surfactants and oil phases than the electrostatic one. • Surface wettability and charge are key factors governing demulsification performance. • The findings provide insights into tailoring MOF surface chemistry for demulsifier development. The role of surface functional groups in metal–organic frameworks (MOFs)-based demulsification remains poorly understood. Herein, four isostructural UiO-66 derivatives (–H, –NH 2 , –NO 2 , –F) were systematically evaluated as discrete demulsifiers for SDS‑stabilized oil‑in‑water emulsions. The study combined batch demulsification tests with measurements of SDS and toluene adsorption, dynamic interfacial tension, surface wettability, and zeta potential. The hydrophobic fluorinated sample (UiO-66-4F) achieved approximately 80% demulsification efficiency, attributed to strong hydrophobic interactions. The hydrophilic yet positively charged amino‑functionalized sample (UiO-66-NH 2 ) also achieved about 80% efficiency, but via electrostatic attraction to the negatively charged oil‑water interface. Unmodified UiO-66 and the nitro derivative (UiO-66-NO 2 ) exhibited lower efficiencies (<65%). Further tests showed that UiO-66-NH 2 was effective only for anionic surfactants, whereas UiO-66-4F was less affected by surfactant charge. Both MOFs showed higher efficiency for aromatic oils than for aliphatic oils. These results identify two distinct design paradigms – hydrophobic capture and electrostatic neutralization – for MOF‑based particle demulsifiers. Tailoring surface hydrophobicity or charge provides effective demulsification depending on the target emulsion chemistry. This work advances the understanding of structure–property relationships in MOF demulsifiers and offers practical guidelines for developing separation materials.

This study developed two novel magnetic nanocomposites with immobilized porcine pancreatic lipase (PPL) for simultaneously removing patulin (PAT) and ochratoxin A (OTA)—two hazardous environmental contaminants—from fruit juices. All detoxification experiments were conducted in real fruit juice matrices (apple juice for PAT, grape juice for OTA) under ambient temperature (25 °C) with realistic contamination ranges. The results demonstrated MNP@UiO-66-(SH)₂@PPL achieved removal rates of 77.03% for PAT in apple juice and 45.03% for OTA in grape juice, while MNP@UiO-66-NH₂@PPL showed removal rates of 85.74% for OTA and 48.44% for PAT. LC-MS analysis indicated that PAT undergoes ring-opening to ascladiol, while OTA is hydrolyzed to phenylalanine and OTα. Molecular docking revealed that PPL spontaneously binds to both toxins via hydrogen bonding and hydrophobic interactions. CCK-8 assays confirmed low cytotoxicity of the materials and their degradation products, with no adverse impact on juice quality. The composites also exhibited magnetic recovery rates > 93%, enabling facile separation and recyclability. This work provides a safe, efficient, and reusable strategy for multi-mycotoxin decontamination with demonstrated environmental relevance.

Rapid and sensitive detection of picric acid (PA), a highly toxic and water-mobile nitroaromatic pollutant, is essential for environmental safety and public health protection. Herein, we fabricate a dual-emission ratiometric fluorescent probe by immobilizing high-load red-emitting carbon dots (R-CDs) onto NH₂-functionalized MIL-53(Al), forming an R-CDs/NH 2 -MIL-53(Al) composite for selective aqueous-phase PA sensing. R-CDs were hydrothermally synthesized with citric acid and neutral red as co-precursors. The loading efficiency was maximized by systematically optimizing precursor molar ratios and dilution conditions. The composite exhibits distinct selective fluorescence quenching in the presence of PA. Mechanistic characterizations, including fluorescence lifetime decay measurements and spectral overlap analysis, verify that the fluorescence quenching originates from two synergistic quenching pathways, namely competitive light absorption and fluorescence resonance energy transfer (FRET), rather than nonspecific physical interactions. This ratiometric sensing platform achieves a wide linear detection range of 0.1–70 μM and an ultralow limit of detection (LOD) of 32.9 nM. Spike-and-recovery assays using real environmental water samples (tap water, commercial bottled mineral water, and Jialing River surface water) produced recoveries of 99.7%–105.1%, with relative standard deviations (RSD) below 5.86% ( n = 3). Furthermore, a smartphone-enabled visual quantitative method based on RGB color channel analysis was constructed, enabling portable on-site detection without large-scale laboratory instrumentation.
