Cellulose-based fabrics are ubiquitous in daily life due to their processability, biodegradability, and flexibility. Integrating cellulose-based fabrics with functional coatings can release their potential functions to participate in various applications. However, the large-scale production of multifunctional fabrics still remains a great challenge. Herein, a multifunctional superhydrophobic hemp fabric (HF) with integrated antibacterial, fluorescent, UV-blocking, self-cleaning, and oil-water separation capabilities was fabricated via an effective interfacial engineering strategy based on diazonium chemistry and MOF assembly. The HF surface was grafted with a polymer layer of benzoic acid via diazonium chemistry, which provided abundant active sites of carboxy group to effectively anchor Ce-MOF. A dense hierarchical morphology was constructed on HF by in-situ growth of Ce-MOF, and a large number of pores were generated by self-assembly, which could be used to load berberine (Ber) and then modified with stearic acid to prepare superhydrophobic fabric. The water contact angle of the modified HF is as high as 154°, and it has good self-cleaning performance. The oil-water separation efficiency of the modified fabric is remarkable (97%), and it can effectively separate light and heavy oil from water. The modified fabric exhibits excellent UV-blocking performance with a high UPF of 70.2. Encouragingly, Ber also endows HF with excellent antibacterial and fluorescence properties. Encouragingly, the tensile strength of HF was not significantly affected. This study not only focuses on the materials design and large-scale fabrication but also provides multifunctional hemp fabrics with broad application prospects for many fields.

The application of Pickering emulsions in interfacial catalysis provides a promising platform for biphasic reactions. Metal–organic frameworks (MOFs), owing to their high surface area, tunable porosity, and flexible functionalization, have emerged as ideal stabilizers for Pickering emulsions in such catalytic systems. Herein, we report the incorporation of PdNi alloy nanoparticles into MIL-101, where the Lewis acidity of the MOF combined with the catalytic activity of PdNi NPs enables two-step one-pot reactions. Interestingly, the resulting bimetallic PdNi@MIL-101 not only acts as an effective emulsifier to stabilize Pickering emulsions, but also exhibits superior performance in the reductive amination of Nitroarenes compared with the corresponding monometallic@MOFs. Moreover, PdNi@MIL-101 demonstrates excellent stability, maintaining high reproducibility after five consecutive cycles. This work not only reduces the catalyst cost, but also exploits the synergistic effect of bimetallic components and interfacial catalysis, which opens up new avenues for efficient and environmentally friendly organic synthesis.

Decarbonization is essential to address climatic variations caused by greenhouse effects. Membrane-based separation processes present an energy-efficient and scalable pathway for flue gas purification. Permeability-selectivity trade-off of polymeric membranes can be mitigated through combined impregnation of bi-fillers within polymer matrix coupled with applying ultrathin secondary polymer coating to fabricate efficacious dual-layer composite membrane. Microporous activated MOF-5 nanocrystals with high surface area and CO 2 affinity, combined with graphene nanoplatelets possessing exceptional CO 2 uptake, were synergistically embedded into flexible polysulfone matrix. Biodegradable poly(vinyl alcohol) coating layer was uniformly deposited onto doped polysulfone substrate, yielding novel class of anisotropic dual-layer mixed matrix composite membranes, rendering drastically improved CO 2 /N 2 selectivity of 70 and upgraded CO 2 permeability of 92 Barrer as compared to bare polysulfone membrane. Advanced characterizations verified uniform nanofiller dispersion, strong interfacial bonding, and enhanced thermal stability. Five percent PVA coating boosted thermal stability and improved mechanical robustness by 84%, markedly strengthening membrane structural and thermal resilience.

Rapid, highly sensitive detection of mustard gas is a critical requirement in public safety and national defense. However, achieving highly sensitive, ppb-level detection of mustard gas under low-power conditions remains a significant challenge. Focusing on the typical blister agent simulant 2-chloroethyl ethyl sulfide (2-CEES), a solvothermal method was employed combined with controlled thermal treatment to fabricate an ultrathin porous NiFe 2 O 4 /NiO nanosheets heterostructure sensor derived from an Fe-Ni-MOF in-situ grown on a ceramic tube in this study. This material possesses uniformly distributed intimate heterogeneous interface, a high specific surface area (95.8 m 2 ·g −1 ), and abundant surface active sites, thereby significantly enhancing its adsorption and catalytic oxidation capability toward 2-CEES. At a low operating temperature of 130 °C, the sensor demonstrates a high response of 41.5 toward 10 ppm 2-CEES, a rapid recovery capability of only 84 s, and a low detection limit of 20 ppb, along with excellent selectivity, humidity resistance, reproducibility, and long-term stability. Through systematic characterization including XPS, in-situ DRIFTS, TPD, and DFT calculations, the multi-step catalytic oxidation pathway of 2-CEES on the composite surface is elucidated, along with the mechanism by which the heterostructure enhances gas-sensing performance via band structure modulation, interfacial charge transfer, and the built-in electric field. This study offers both new materials and novel insights for the development of low-power, highly sensitive sensors for trace detection of chemical warfare agents.

Fe/Cu bimetallic MOFs are directly grown on carbon cloth substrates. • Bimetallic sites regulate water states and reduce evaporation enthalpy to 1250.8 J g −1 . • Fully hydrophilic channels accelerate water transport with 20 ms ultrafast wetting. • The evaporator achieves 2.31 kg m −2 h −1 evaporation with excellent salt tolerance. • The flexible evaporator enables efficient solar desalination and dye removal. Solar interfacial evaporation (SIE) is regarded as a sustainable strategy for addressing global freshwater scarcity. However, further breakthroughs in evaporation efficiency are fundamentally restricted by the thermodynamic bottleneck of the high latent heat of water vaporization. Although metal-organic frameworks (MOFs) have shown promise in modulating the water state, the fixed electronic environment of conventional monometallic MOFs struggles to achieve a delicate balance between water adsorption and desorption, thereby limiting the maximization of continuous vapor generation. Herein, we construct a highly efficient, flexible, and self-cleaning FCMC evaporator by growing Fe/Cu bimetallic MOFs on a carbon cloth (CC) substrate. Benefiting from the synergistic charge rearrangement between the bimetallic Fe/Cu nodes, the composite optimizes the binding energy with water molecules and effectively disrupts the hydrogen-bond network. This significantly increases the proportion of intermediate water, reducing the evaporation enthalpy (DSC-derived) of confined water to 1250.8 J g −1 . Concurrently, the unique fully hydrophilic channels of the FCMC exhibit an ultrafast wetting behavior within milliseconds (20 ms). This induces a robust kinetic pumping effect that ensures a sufficient water supply during high-flux evaporation. Driven by this “dual-engine” mechanism—thermodynamic water activation and kinetic transport acceleration—the FCMC achieves an outstanding evaporation rate of 2.31 kg m −2 h −1 under 1-sun illumination. Furthermore, the device demonstrates remarkable salt-reflux capabilities and efficient rejection of organic dyes. This work integrating bimetallic electronic regulation with a fully hydrophilic interfacial design, provides a new pathway for developing next-generation, high-performance, and salt-resistant devices for solar desalination and wastewater purification.

Developed a unique Gd-doped Tourmaline@MOF-ZnO nanostructure that integrates a polarized core with a highly porous shell. • Achieved a massive response (890.31 to 100 ppm), fast kinetics (34 s/18 s), and a ppb-level detection limit (56.63 ppb) for n-butanol at 240 °C under UV activation. • The gas-sensing performance is significantly boosted through the synergistic combination of the MOF-derived porous architecture, Tourmaline polarization, Gd-induced oxygen vacancies, and UV activation. Reliable monitoring of volatile organic compounds (VOCs) demands gas sensors with fast response, high sensitivity, and excellent selectivity. To this end, we designed a novel gas-sensing material based on a Gd-doped Tourmaline@MOF-ZnO core–shell nanostructure. This structure integrates a Tourmaline core with a porous MOF-derived ZnO shell, further enhanced via Gd doping. The gas sensing properties were evaluated under both dark condition and UV activation. At the operating temperature of 240 °C with UV activation, the optimized sensor with 0.08 wt% Gd and 5 wt% Tourmaline (denoted as 0.08 wt% Gd-5 wt% TML@ZnO) exhibited a remarkable response of 890.31 to 100 ppm n-butanol. This value is 9.96 times higher than that of the pristine MOF-derived ZnO (89.43). Moreover, the sensor demonstrated fast response/recovery times (34 s/18 s), high selectivity, excellent long-term stability, and a low detection limit of 56.63 ppb. The outstanding performance underscores the considerable promise of the optimized Gd-doped Tourmaline@MOF-ZnO core–shell composite for practical ppb-level VOCs monitoring. This work provides an effective strategy for designing high-performance gas sensors through the synergistic integration of rare-earth doping and core–shell structural design.

MXene-MOF architectural hybrid is prepared for fluoride adsorption. • MSCes exhibit excellent salt tolerance for fluoride adsorption. • MSCes enable efficient fluoride adsorption over a broad pH range. • MSCes perform well in complex environmental samples. Currently, excessive fluoride contamination in groundwater poses a serious threat to drinking water safety, highlighting the need for efficient, simple, and cost-effective strategies for fluoride removal and analysis. Herein, a MXene-engineered Ce-based UiO-66 (MSCe) hybrid is developed for selective fluoride capture and preconcentration from complex water samples. Benefiting from abundant exposed metal sites, reduced interfacial binding resistance, and accelerated mass transfer enabled by MXene engineering, MSCe exhibits excellent structural stability, a broad applicable pH range, high adsorption capacity, and outstanding selectivity toward fluoride. Notably, MSCe maintains excellent fluoride-capture performance even under high-salt conditions, demonstrating its strong tolerance to complex ionic matrices. Among the investigated composites, MSCe-V exhibits the highest adsorption capacity of 218.0 mg g -1 , compared with 194.6 mg g -1 for MSCe-Ti-15, with equilibrium reached within 100 min. The adsorption process followed the pseudo-second-order kinetic and Langmuir isotherm models. This work provides a promising MXene-MOF hybrid platform for selective fluoride preconcentration and expands their application in sample preparation.

Excessive multi-site confinement impairs induced-fit Cd 2+ aptamer binding. • Ag-MOF/Pen co-regulation balances structural rigidity and binding flexibility. • Interfacial anchoring and H-bond regulation enhance apparent affinity 16.1-fold. • Label-free fluorescence enables accurate Cd 2+ analysis in pea seedling tissues. Aptamer immobilization can improve structural stability, but excessive confinement may restrict the conformational rearrangements required for induced-fit target recognition. A key challenge is therefore to stabilize recognition-competent conformations while preserving the structural adaptability required for binding. Using a Cd 2+ aptamer as a model, we first demonstrated that conventional multi-site immobilization increased the apparent dissociation constant by approximately eightfold relative to the free aptamer. To address this issue, we developed a surface-imprinting strategy that confines the aptamer within hydrogel through single-point tethering of the aptamer while modulating its local microenvironment. The Cd 2+ -bound aptamer was first assembled on Ag-MOF, followed by hydrogel polymerization in the presence of penicillamine. During imprinting, Ag-MOF promoted localized aptamer anchoring, while penicillamine regulated the hydrogen-bonding network surrounding the Cd 2+ -aptamer complex. Subsequent Cd 2+ removal generated an imprinted microenvironment that partially preserved the preorganized recognition conformation without over-constraining flexible regions required for rebinding. The optimized hybrid exhibited an apparent dissociation constant of 0.19 μM, corresponding to a 16.1-fold decrease relative to the free aptamer, and reached binding equilibrium within 10 min. Integration with label-free Tb 3+ -sensitized fluorescence enabled Cd 2+ detection with a limit of detection of 0.7 nM, approximately 1.1–1114-fold lower than nine representative reported methods, while maintaining satisfactory selectivity and reproducibility. The method was further validated by quantifying Cd²⁺ in different tissues of hydroponically grown pea seedlings and food matrices, with results consistent with ICP-MS. These results establish moderate, microenvironment-assisted confinement as a general design principle for balancing conformational stabilization and induced-fit adaptability at aptamer recognition interfaces.

The Sn-MOF reconstructed into a SnO nanoflower structure only upon electrolyte immersion. • The SnO nanoflower achieves >92% formate Faradaic efficiency in both H-cell and flow cell. • Its abundant grain boundaries and edge sites enhance the adsorption and stabilization of the *OCHO intermediate. • The nanoflower morphology remains stable during CO 2 reduction, contributing to sustained catalytic performance. Sn-based materials are promising for electrochemical CO 2 reduction to formate, yet the real active species and structural evolution under operating conditions remain elusive. Here, we track the spontaneous, potential-independent reconstruction of a Sn-terephthalic acid framework (Sn-PTA) in KHCO 3 electrolyte, revealing a two-stage transformation that dictates catalytic performance. Initially, the MOF decomposes into nanoflower-like SnO assemblies (Sn-PTA-180), characterized by abundant grain boundaries and edge sites that maximize active surface exposure. This metastable intermediate exhibits superior intrinsic activity, achieving a 92.7% formate Faradaic efficiency (FE) at 38.9 mA cm −2 in an H-cell and maintains 92.6% FE at 200 mA cm −2 in a flow cell. In situ ATR-SEIRAS correlates this performance to the optimized adsorption and stabilization of the *OCHO intermediate on the unique nanoflower architecture. Furthermore, we demonstrate that under cathodic bias, SnO undergoes a phase transition to metallic Sn while perfectly inheriting the advantageous morphology. This work elucidates electrolyte-driven MOF reconstruction as a powerful in situ route to engineer catalytically active interfaces, offering a new paradigm for designing high-performance pre-catalysts for efficient CO 2 -to-formate conversion.

A bimetallic spinel Mn 0.8 Co 2.2 O 4 catalyst was successfully synthesized for PMS activation • Mn 0.8 Co 2.2 O 4 /PMS gains 100% OFX removal (25 min), 76.96% PMS use, 96.9% TOC removal • Coexisting radical and nonradical pathways via Co/Mn redox and oxygen vacancies • DFT confirmed Mn doping improved PMS adsorption, O O bond elongation, and d-band upshift • The catalyst exhibited excellent stability, reusability, and broad-spectrum applicability Ofloxacin (OFX), a recalcitrant fluoroquinolone antibiotic, poses significant risks to ecosystems and human health, necessitating the development of efficient remediation technologies. In this study, a bimetallic spinel Mn 0.8 Co 2.2 O 4 catalyst was successfully synthesized via pyrolysis of a CoMn-BTC metal-organic framework precursor and employed for peroxymonosulfate (PMS) activation toward OFX degradation. The incorporation of Mn into the Co 3 O 4 lattice induced lattice distortion, enlarging specific surface area (45.3 m 2 /g), and enriching Co 2+ content (58.34%), oxygen vacancies, and hydroxyl groups, thereby enhancing electron transfer capability and redox activity. The Mn 0.8 Co 2.2 O 4 /PMS system achieved complete OFX removal within 25 min (k = 0.14219 min −1 ), 1.78 times higher than pristine Co 3 O 4 , with high PMS utilization (75.96%) and near-complete mineralization (96.9% TOC removal). The catalyst exhibited excellent stability over five cycles with minimal metal leaching (Co: 0.365 mg/L, Mn: 0.079 mg/L) and maintained high efficiency (≥88.81%) across pH 3–11. Both radical (•O 2 − , SO 4 •- , •OH) and non-radical ( 1 O 2 , Co(IV) = O) pathways contributed, with 1 O 2 and •O 2 − predominant, with Co/Mn redox cycles and oxygen vacancies serving as key active sites. Electrochemical analysis and density functional theory calculations further confirmed that Mn doping enhanced PMS adsorption energy, elongated the O O bond, facilitated interfacial electron transfer, and shifted the d-band center closer to the Fermi level, thereby boosting catalytic activity. Three plausible degradation pathways were proposed based on reactive site analysis and intermediate identification. This work provides fundamental insights into Mn-doped cobalt spinel for Fenton-like PMS activation and demonstrates their potential as efficient, stable catalysts for antibiotic-contaminated wastewater remediation.

Helium (He) recovery via conventional cryogenic distillation is highly energy-intensive and costly. Membrane separation features modularity and efficiency, but mixed-matrix membranes (MMMs) often suffer from discontinuous channels and poor filler–polymer compatibility, which impair separation performance. Here, we report an MMM platform by embedding a continuous 3D nanoporous ZIF-67-NH 2 gel within a polyimide matrix. The gel functions as a dual-functional crosslinker, forming covalent amide linkages and hydrogen bonds with the polymer to eliminate interfacial voids, while creating interconnected, selective nanochannels through its intrinsic nanoporosity. This yields He/CH 4 performance: 549 Barrer He permeability and 110.3 selectivity, surpassing the benchmark membranes. The membrane retains over 95% performance in mixed-gas tests over 180 h. Process simulations show that a hybrid membrane–cryogenic system achieves >93% He recovery and 74% energy savings. This work provides an energy-efficient platform for critical gas separations.

Sonodynamic therapy (SDT) offers deep tissue penetration and noninvasive tumor treatment, yet its efficacy remains limited by inadequate reactive oxygen species (ROS) generation and an immunosuppressive tumor microenvironment (TME). In this work, we developed a porphyrin-based bimetallic nanoplatform by integrating Fe and Mn centers within a structurally ordered metal-organic framework (MOF), followed by surface modification with the tumor-homing peptide CRGDK to achieve active targeting. The rationally engineered Mn-Fe(TCPP) MOF exhibits a spatially confined configuration that minimizes π-π aggregation of porphyrins enhancing ROS production under ultrasound (US). Meanwhile, Fe 3+ and Mn 2+ are released in the mildly acidic TME. The Fe 3+ catalyzes Fenton-like reactions to generate abundant •OH radicals, leading to glutathione (GSH) depletion, glutathione peroxidase-4 (GPX4) inhibition, and triggers ferroptosis. Simultaneously, Mn 2+ and ROS inflict mitochondrial damage and cause cytosolic double-stranded DNA (dsDNA) leakage, thereby activating the cGAS-STING signaling pathway and amplifying type I interferon (IFN-I) responses. This dual immunometabolic modulation induces immunogenic cell death (ICD), promotes dendritic cells (DCs) maturation, and strengthens adaptive antitumor immunity. Overall, this study presents a concise strategy coupling ferroptosis induction with innate-immune activation through a porphyrinic bimetallic MOF, offering a promising direction for SDT-based immunotherapy against hard-to-treat tumors.
