Structured adsorbents capable of combining strong low-pressure CO 2 affinity, high selectivity, and humidity tolerance are highly desired for low-concentration CO 2 capture, yet remain difficult to realize because shaping often compromises porosity and mass transport. Here, we report a solvent-directed and nanoconfined crystallization strategy to construct millimeter-sized polyacrylate (PA)-supported Zn 2 (Mtz) 2 Ox-EG sphere (Zn 2 (Mtz) 2 Ox-EG@PA). Ethylene glycol modulates the ultramicroporous environment of Zn 2 (Mtz) 2 Ox, enhancing its low-pressure CO 2 affinity, while the confined macroporous network of the PA matrix promotes heterogeneous nucleation and suppresses free crystal growth, sharply reducing the size of the micrometer-scale MOF bulk crystals by nearly 100-fold. The resulting Zn 2 (Mtz) 2 Ox-EG@PA composite exhibits a high CO 2 uptake for 1.68 mmol g −1 at 0.05 bar and 313 K, while N 2 and CH 4 adsorption are strongly suppressed. Consequently, high IAST selectivities of 3447 for CO 2 /N 2 and 1275 for CO 2 /CH 4 are achieved at a 5/95 gas ratio. The hydrophobic MOF framework and PA matrix endow the composite with excellent hydrothermal durability, retaining framework integrity after hot-water treatment at 403 K for 7 days. Dynamic breakthrough experiments further demonstrate efficient CO 2 /N 2 separation from a 5 vol% CO 2 stream at 90% RH, highlighting the potential of nanoconfined MOF crystallization for robust structured adsorbents under humid dilute-CO 2 conditions.

A Bi 2 WO 6-x @MOF heterostructure is fabricated via surface engineering combining oxygen vacancies with in-situ MOF growth. • The Bi–O bridged heterointerface effectively shields surface oxygen vacancies from oxidative deactivation. • Directional charge transfer from Bi 2 WO 6-x to Bi-MOF fragments significantly suppresses photogenerated carrier recombination. • Superoxide anion radicals (·O 2 - ) are identified as the dominant reactive species driving antibiotic mineralization. Oxygen vacancies (Ov) can significantly enhance the photocatalytic activity of metal oxide semiconductors, yet their susceptibility to oxidative deactivation under reaction conditions severely limits long-term stability. Herein, we report a surface engineering strategy to construct a Bi 2 WO 6-x @MOF heterostructure, where Bi-MOF layer is grown in situ onto oxygen-deficient bismuth tungstate nanosheets. The Bi–O bridged heterointerface not only preserves the surface Ov from oxidative erosion but also promotes directional charge transfer from the oxide substrate to the MOF particulates, as evidenced by XPS, EPR, and time-resolved photoluminescence. The Bi 2 WO 6-x @MOF achieves a levofloxacin degradation efficiency of 73.1% under simulated solar irradiation, substantially outperforming pristine Bi 2 WO 6 (44.4%) and defective Bi 2 WO 6-x (53.7%), while maintaining stable activity over five recycling runs. Mechanistic studies, including radical trapping and EPR spectroscopy, identify superoxide anion radicals (·O 2 - ) as the dominant reactive species. DFT calculations further reveal that interfacial Bi–O coordination lowers O 2 adsorption energy barrier to 0.477 eV on the Bi 2 WO 6-x @MOF and facilitates the formation of ·O 2 - . This work demonstrates that MOF encapsulation, when coupled with proper electronic modulation, offers a robust route to simultaneously stabilize defects and boost photocatalytic performance for antibiotic wastewater treatment.

Constructing mixed-matrix membranes (MMMs) in which porous fillers effectively contribute to gas transport remains challenging, especially in highly permeable polymer matrices where gas diffusion is often dominated by the polymer phase or non-selective interface. Here we show interfacially integrated oriented MMMs based on homologous microporous polymer-grafted ZIF-8 nanosheets for CO 2 /CH 4 separation. Acyl chloride-functionalized PIM-1 was covalently grafted onto amino-functionalized ultrathin ZIF-8 nanosheets. This interlayer improves the compatibility between ZIF-8 nanosheets and the PIM-1 matrix while preserving the accessible nanopores of ZIF-8, enabling uniform nanosheet dispersion and preferential in-plane alignment during membrane fabrication. Structural characterizations and molecular simulations reveal an integrated filler–interlayer–matrix structure involving covalent bonding and polymer-chain inter-penetration, which suppresses non-selective gas transport and allows the oriented ZIF-8 nanosheets to contribute more effectively to diffusion-based molecular sieving. The optimized membrane with 40 wt% grafted nanosheets exhibits a CO 2 permeability of 5890 Barrer and CO 2 /CH 4 selectivity of 26.8 under mixed-gas conditions. Furthermore, the interpenetrated PIM interface improves aging resistance, allowing the membrane to retain 79.7% of its initial CO 2 permeability after 120 days. This work offers a practical interfacial engineering strategy for constructing high-loading oriented MOF nanosheet MMMs with enhanced selectivity and long-term stability.

Diatomite-induced amino coordination transformation Bi-MOF composite was prepared. • Surface silanol groups modulate Bi 3+ coordination, inducing amino ligand transformation. • The coordination transformation forms highly dispersed NH 2 -Bi-MOF nanowhiskers. • The composite shows enhanced photocatalysis, cycling stability and lower costs. Developing photocatalysts featuring outstanding catalytic activity and economic viability contributes greatly to artificial carbon cycling and addressing energy and environmental challenges. In this study, we adopted a strategy combining amino ligand modification with diatomite support to successfully synthesize amino-modified NH 2 -Bi-MOF/diatomite composites. These materials utilize the silanol groups on the diatomite surface to modulate the coordination environment of the Bi 3+ metal centers, inducing the conversion of amino ligands and promoting the formation of Bi-N bonds, thereby transforming the morphology of the NH 2 -Bi-MOF from an agglomerated state to highly dispersed nanowhiskers. The characterization results indicate that the highly dispersed structure endows the material with outstanding chemical stability, light-harvesting capability, CO 2 adsorption capacity, and carrier separation efficiency. Meanwhile, the optimal sample, NH 2 -Bi-MOF/diatomite-0.2, achieves a CO production rate of 10.440 μmol·g −1 ·h −1 , representing increases of 78% and 45% compared to Bi-MOF and NH 2 -Bi-MOF, respectively. Notably, no apparent decline in catalytic performance was observed after four cycles. Furthermore, the introduction of diatomite substantially reduces catalyst preparation costs. This study also systematically elucidates the conversion mechanism of amino ligands and the interfacial synergy between diatomite and NH 2 -Bi-MOF, clarifying the photocatalytic CO 2 reduction pathways and core mechanisms of the composite material. The findings provide new insights for the development and industrial application of highly efficient and economical photocatalysts.

A multifunctional nanocomposite, composed of Ga-loaded Ce-MOF core and NO-responsive microgel shell, is designed to integrate effective drug loading, controlled drug release and multi-target synergy to therapy RA. • The Ga-loaded Ce-MOF core functions dually as a high-capacity drug carrier of natural compound and a nanozyme with superoxide dismutase/catalase-like activities for reactive oxygen species (ROS) elimination, effectively alleviating oxidative stress damage in RA and establishing initial synergistic effects with Ga intrinsic anti-inflammatory activity. • The NO-responsive microgel shell acted as pathological cue-triggered “gatekeeper”, enabling on-demand drug release specifically at inflammatory sites while concurrently scavenging excessive NO to synergetic treat RA. • The nanocomposite significantly inhibits pro-inflammatory cytokines, alleviates cartilage degradation and bone erosion by eliminating excessive RONS, promoting the repolarization of macrophages from M1 to M2 phenotypes, and regulating the MAPK and cGMP/PKG signaling pathways. • This “one-stone-three-birds” strategy that integrating natural drug therapy, stimuli-responsive drug release with synergistic RONS scavenging and immune homeostasis modulation, offers an innovative and efficient approach for treatment of RA and other inflammatory diseases. Rheumatoid arthritis (RA) is a chronic autoimmune disorder characterized by persistent inflammatory injury and progressive destruction of joints. The elimination of excessive reactive oxygen and nitrogen species (RONS) and the restoration of immune homeostasis have emerged as promising therapeutic strategies for RA. Gastrodin (Ga), a bioactive natural constituent derived from Gastrodia elata, possesses inherent antioxidant and anti-inflammatory capacities, whereas its clinical translation and in vivo utility are substantially hampered by inferior environmental stability and uncontrollable drug release behavior. Herein, we fabricated a nitric oxide (NO)-responsive nanocomposite (NCMG) consisted of a Ce-based metal-organic framework (Ce-MOF) nanozyme loaded with Ga and encapsulated by a NO-responsive microgel shell for synergistic RA treatment. The Ce-MOF serves dual functions as a high-efficiency drug carrier and reactive oxygen species (ROS) scavenger, while the outer microgel shell enables precise on-demand Ga release and efficient NO depletion. In vitro experiments and in vivo validation based on adjuvant-induced arthritis (AIA) rat models demonstrated that NCMG markedly inhibits the secretion of pro-inflammatory cytokines, induces macrophage polarization from the pro-inflammatory M1 phenotype to the anti-inflammatory M2 phenotype, and effectively alleviates joint inflammation and bone erosion. Transcriptomic profiling further showed that Ga treatment was associated with downregulation of Il1b and Tnf and alterations in MAPK related gene expression, suggesting the involvement of this pathway in its anti-arthritic activity. This work develops an integrated nanotherapeutic platform combining natural active compounds with multi-component synergistic effects, offering a feasible strategy for RA intervention.

Developing cost-effective bifunctional oxygen catalysts with robust activity and stability remains a core challenge for rechargeable zinc-air batteries (ZABs), primarily hindered by the slow kinetics of oxygen reduction/evolution reactions (ORR/OER). Herein, we report a Fe/Co-based composite catalyst, P-Fe-ZIF67@PI-COF-T (T represents calcination temperature), which is constructed by using a polyimide-based covalent organic framework as a support, followed by phosphorization and high-temperature pyrolysis of ZIF67 (zeolitic imidazolate framework67). Electrochemical measurements demonstrate outstanding bifunctional performance: an ORR half-wave potential (E 1/2 ) of 0.81 V, an OER overpotential of 250 mV at 10 mA cm −2 , and a ΔE of 0.67 V. The corresponding ZABs exhibit a high peak power density of 142.8 mW cm −2 and long-term durability for 300 h. Systematic analysis attributes the excellent performance to the synergistic effects of N/P co-doping induced defects, and the graphitized carbon layer. This study provides a rational design principle for advanced non-noble metal catalysts.

• Co/TiO 2 @C composites are derived from bimetallic MOF. • • Minimum reflection loss of −64.5 dB at 1.8 mm thickness is achieved. • • Effective absorption bandwidth of 3.2 GHz in X-band. • • Hierarchical structure boosts interfacial and dipole polarization. In this study, disk-shaped MIL-125(Ti,Co)- x precursors were synthesized via a solvothermal method with varying CoCl 2 ·6H 2 O content, and subsequently Co/TiO 2 @C composites were fabricated through a two-step pyrolysis process. The precursor morphology transforms from intact micron-scale disks into thinner flakes, and ultimately into fragmented structures with increasing the cobalt content. The pyrolysis temperature concurrently governed the composition of TiO 2 phase, the degree of carbon graphitization, and the distribution of nanoparticles. The optimized Co/TiO 2 @C(700)-2 composite achieves a minimum reflection loss of −64.5 dB at a matching thickness of 1.8 mm, and exhibits an effective absorption bandwidth of 3.2 GHz at 2.1 mm. The outstanding electromagnetic wave absorption properties stem from a favorable synergy between adequate attenuation and satisfactory impedance matching, supported by the conductive carbon network, abundant defect sites, multiple TiO 2 /carbon heterointerfaces, and hierarchical porous architecture. These results establish the cooperative regulation of electromagnetic wave absorption properties by cobalt content and pyrolysis temperature, offering a strategy for the design of MOF-derived lightweight absorbers with tunable electromagnetic wave absorption.

Corrosion poses a critical threat to industrial safety and service life of metallic materials, yet conventional protective coatings lack the responsive functionality for long-term active protection. To address this limitation, a pH-responsive core-shell nanocontainer is designed to achieve intelligent corrosion protection by integrating active inhibitor release and passive barrier enhancement. The nanocontainer consists of dendritic silica (DPS) as a porous core for loading corrosion inhibitors, encapsulated by a ZIF-67 shell that responds to local pH changes. When incorporated into a waterborne epoxy coating, the system demonstrates both on-demand self-healing at defect sites and long-term barrier stability. Electrochemical tests showed that the |Z| 0.01 Hz of the composite coating remained at 3.3 × 10 7 Ω·cm 2 after immersion in 3.5 wt% NaCl solution for 28 d, and the charge transfer resistance at a scratch was about 4.6 times higher than that of the blank coating after 48 h. This work presents a novel design approach for multifunctional anticorrosion coating with combined active and passive protection mechanisms.

Polypropylene (PP) is a widely used thermoplastic resin known for its strong properties, including chemical stability, electrical insulation, and high abrasion resistance. However, its low ignition point and rapid burning rate pose significant fire risks, necessitating the incorporation of flame retardants. In this study, cobalt metal–organic framework (Co-MOF), melamine polyphosphate (MPP), and expandable graphite (EG) were combined to enhance the flame retardancy of PP. The optimal blending ratio was determined, and the results showed that PP/MPP/2 mass% Co-MOF/15 mass% EG composites exhibited superior flame retardancy. These composites achieved a critical oxygen index (LOI) of 28%, a V-0 rating in the UL-94 test, and significantly reduced heat release and smoke production during combustion. The synergistic effect of MPP, Co-MOF, and EG facilitated the formation of a dense, thermally stable carbon layer, which effectively hindered flame propagation and improved fire safety. These findings provide valuable insights for the development of flame-retardant PP materials. Graphical abstract

In this work, a high-sensitivity electrochemical sensor was developed using a hybrid strategy, where sheet-like MXenes-based composites (Bi-MOF/MXenes) were prepared through the in-situ growth of bismuth-based metal-organic frameworks (Bi-MOF) on the MXenes surface. This hybrid composite material was fabricated using a simple physical synthesis method, which maintains excellent electrocatalytic activity while enhancing the electron transfer rate and electroactive surface area. The Bi-MOF/MXenes modified electrode has been demonstrated to be an effective tool for the detection of nitrite. The electrode exhibited a remarkable limit of detection (LOD) of 0.028 μM and a wide linear range of 0.5~4715 μM. The sensor exhibited remarkable repeatability and reproducibility, with relative standard deviation (RSD) values of 1.74% and 4.87%, respectively. The proposed approach was effectively utilized for detecting nitrite in sausage and fermented bean curd.

Drug repurposing has received increasing attention in the field of oncology drug development as an alternative strategy to de novo drug synthesis. Disulfiram (DSF) has a long history of clinical application in alcohol withdrawal, and recent studies have revealed that its metabolite diethyldithiocarbamate (DDTC) can be coordinated with copper ions in vivo to form Cu-DDTC complexes with anticancer activity. However, the insufficient in vivo stability of DSF remains a challenge. In this study, the nanomedicine Cu-BTC@DDTC with DDTC-Cu(I) chemical valence and polycrystalline structure was prepared by incorporation of DDTC into the nanosized metal–organic framework (MOF) Cu-BTC. The in vitro cellular evaluation results showed that Cu-BTC@DDTC exhibited high inhibition of tumor cell growth, migration, and invasion. Animal experiments on the xenograft tumor model further demonstrated the excellent antitumor activity and biosafety of Cu-BTC@DDTC, and the antitumor activity was found to be closely related to the regulation of the SLC7A11/GPX4 signaling pathway to induce ferroptosis. This study provides a feasible option for antitumor drug development based on a drug repurposing strategy.

Reasonable heterogeneous interface engineering is crucial for achieving efficient and robust oxygen reduction reactions (ORR). Herein, a ferrocene enhanced interface coupling catalyst has been successfully developed, which consists of cobalt‑nitrogen-doped carbon dodecahedra (Co@NC) with cobalt-ferrocene MOF nanosheets (Co-FcDC). The Co@NC/Co-FcDC catalyst demonstrates superior ORR electrocatalytic activity with a half-wave potential of 0.82 V and a good durability. This promoted performance is attributed to the Fc-enhanced interface coupling interaction between Co-FcDC and Co@NC, which optimizes the electron structure of Co nanoparticles (NP s), increases oxygen adsorption, and reduces the energy barrier for converting O-containing intermediates (*OH) into OH − . This research offers a valuable perspective for the reasonable construction of ferrocene-based heterogeneous interfaces for energy storage and conversion.
