Ag was loaded onto Sn-PTA-MI by the photodeposition method. • Dark reaction experiment confirms Sn-PTA-MI/Ag has the “memory catalysis” effect. • “Memory catalysis” effect boosted by free radical chain reaction from released electrons. • Alternating light-dark reaction enhances utilization efficiency of photogenerated carriers. • PDOS spectroscopy confirms strong interaction between Ag atoms and N, C atoms. A Sn-PTA-MI/Ag photocatalyst with “memory catalysis” effect was prepared by the photodeposition method to load Ag onto Sn-based metal-organic framework (MOF), and the “memory catalysis” effect was confirmed by photoreaction, dark reaction, and alternating light-dark reaction experiments. Under photoreaction, the degradation efficiency of methyl orange (MO) catalyzed by Sn-PTA-MI/Ag reached 90.7% in 60 min. The pre-illumination activation of the Sn-PTA-MI/Ag catalyst facilitated the storage of photogenerated electrons, which are released under dark reaction conditions and subsequently participate in MO degradation. Meanwhile, the “memory catalysis” effect can be significantly enhanced through the free radical chain reaction triggered by the released electrons under dark reaction. The alternating light-dark reaction process achieves continuous degradation of MO, and compared to traditional photocatalytic reactions, the degradation effect of MO is improved by approximately 10%. Projected density of states (PDOS) and Fermi level analysis indicate that strong interactions exist between Ag atoms and N, C atoms, confirming that the optimization of electronic properties and the enhancement of charge separation in the Sn-PTA-MI/Ag system are the main reasons for the increase in activity. This study provides a strategy for the continuous degradation of pollutants, which is of great significance for sustainable environmental remediation.

Despite their high energy density, lithium metal batteries (LMBs) remain hindered in practical applications by the intrinsic instability of the lithium metal anode. Owing to its high reactivity, lithium readily forms a fragile and heterogeneous solid electrolyte interphase (SEI), leading to nonuniform Li deposition, dendrite growth, and consequent safety risks and rapid capacity decay. In this work, a quasi-solid-state electrolyte (QSE) incorporating a BiF 3 -decorated metal-organic framework (MOF) is developed to stabilize lithium metal anodes. The BiF 3 nanoparticles confined within the MOF regulate the Li + solvation sheath through interactions with solvent molecules, thereby facilitating Li + transport and delivering an ionic conductivity of 2.0 mS cm −1 with an enhanced Li + transference number of 0.48. In addition, the QSE promotes the in-situ formation of a LiF/Li 3 Bi-rich SEI, which accelerates Li + diffusion, lowers the Li nucleation barrier, and enables uniform and smooth lithium deposition. As a result, lithium metal anodes exhibit markedly improved reversibility and interfacial kinetics. Li||Li symmetric cells achieve a high critical current density of 2.5 mA cm −2 and maintain stable cycling for over 4600 h at 0.2 mA cm −2 . Furthermore, Li||LiFePO 4 full cells demonstrate excellent rate capability and long-term cycling stability, retaining 92.2% of the initial capacity after 1500 cycles at 1C and delivering 72.6 mAh g −1 at 20C. A BiF 3 -MOF composite electrolyte is designed for lithium metal batteries. The BiF 3 nanoparticles within the MOF effectively modulate the Li + solvation sheath by interacting with solvent molecules and thus facilitate efficient Li + transport. Moreover, the QSE promotes the formation of a LiF/Li 3 Bi-rich SEI, which accelerates Li + diffusion, lowers the nucleation barrier, and enables uniform and easy Li deposition.

In situ growth of ZnCo MOF on 3D-flower like Bi 2 WO 6 is developed for enhancing photocatalytic degradation. • The novel flower-like structure the surface-grown MOF achieved a 99.1% degradation of rhodamine B within 1 h. • The structure causes narrowed the band gap and synergistic charge separation for almost complete photodegradation. Herein, a novel 3D flower-like ZnCo MOF-modified Bi 2 WO 6 is first fabricated via a simple solvothermal approach and applied for complete rhodamine B (RhB) photocatalytic degradation. First, granular flower-shaped BWO and cubic MOF are synthesized. The crystal structure, microscopic morphology, and surface element distribution of these materials are characterized, and their photocatalytic degradation performance toward RhB is evaluated. To clarify the feasibility of modifying the optical catalytic performance of BWO by MOF, a synergistic BWO-MOF composite photocatalyst was prepared, and an extremely high efficiency of 99.1% in the degradation of Rhodamine B within 1 h is achieved. Photoelectrochemical measurements are performed to verify the enhanced separation and transfer of photogenerated charges. Meanwhile, a plausible visible-light-driven photocatalytic degradation mechanism for the BWO/MOF system is proposed, which provides a theoretical basis for regulating photogenerated charge separation and achieving efficient photocatalytic degradation.

The ubiquitous presence of emerging contaminants (ECs) such as antibiotics and synthetic dyes in aquatic systems necessitates advanced remediation technologies. However, conventional polyvinylidene fluoride (PVDF) membranes often suffer from severe fouling and rapid flux decline due to their inherent hydrophobicity, severely limiting their long-term applicability. This study presents the rational design of Ti-MOF/CN/PVDF composite membranes via integrated solvothermal synthesis of Ti-MOF/g-C 3 N 4 (CN) heterojunctions and nanoparticle-regulated phase inversion. Comprehensive characterization (XRD, XPS, SEM-EDS, BET, AFM) confirmed the successful fabrication of the heterojunction membrane. XPS and XRD analyses confirmed the formation of covalent bonds at the (Ti-O-N) interface and lattice strain induced by the nanoparticle filler, effectively suppressing PVDF crystallization. Ti-MOF/CN exhibits a unimodal particle size distribution (D50 ≈ 400 nm) and high BET specific surface area (72.44 m 2 g −1 ). Its uniform dispersion in PVDF increases the membrane pore size from 28.1 nm in pristine PVDF to 38.7 nm at 1 wt% Ti-MOF/CN, significantly enhancing the overall porosity. The top-performing M3 composite membrane demonstrated exceptional multifunctionality: it achieved retention rates exceeding 90% for multiple dyes (Rhodamine B, Methyl Blue, Malachite Green) and antibiotics (Tetracycline). Long-term retention experiments were conducted on complex wastewater containing mixed dyes, alongside photodegradation tests under simulated solar radiation conditions (AM 1.5G, 100 mW cm −2 ). Results indicate over 95% retention of mixed pollutants. Visible light irradiation significantly enhances the M3 membrane's FRR to 91.6%, further demonstrating the Ti-MOF/CN composite membrane's robust long-term operational stability and self-cleaning capability for photocatalytic degradation of aqueous pollutants.

Amorphous metal-organic frameworks (aMOFs), owing to their abundant defects and unsaturated coordination sites, have emerged as ideal precursors for investigating electrocatalytic reconstruction mechanisms. However, a systematic understanding of how different modulation strategies affect the reconstruction pathways of amorphous MOFs and thereby determine the nature of the final active species remains lacking. In this study, an amorphous MOF constructed from 3,4,9,10-pyrene-tetracarboxylic acid (PTA) was employed as a controllable precursor platform to systematically compare two classical strategies (doping and alloying) in terms of their effects on structural reconstruction and oxygen evolution reaction (OER) performance. The results reveal that doping promotes preferential reconstruction into Fe-rich (oxy)hydroxides with more exposed active sites, whereas alloying tends to yield Fe-Co mixed (oxy)hydroxides with limited site exposure. Benefiting from this difference, the doped system FeCo 0.05 -PTA exhibits outstanding OER activity under alkaline conditions, with overpotentials of only 208 and 248 mV at 50 and 100 mA cm −2 , respectively, and a low Tafel slope of 36.2 mV dec −1 . In situ Fourier transform infrared spectroscopy (FTIR) captures the OOH* intermediate, confirming that the reaction follows the adsorbate evolution mechanism; density functional theory (DFT) calculations further demonstrate that the doped system possesses the lowest free-energy barrier (Δ G = 0.59 eV) at the rate-determining step. This study underscores the decisive role of precursor design in this system, elucidates the distinct effects of doping and alloying on the reconstruction pathways and final properties of amorphous MOF-derived (oxy)hydroxides, and provides valuable insights for the design and mechanistic understanding of related electrocatalysts.

Renewable cellulose fibers can be mechanically disintegrated into micro-/nanoscale fibrils with tunable dimensions, offering a sustainable and processable scaffold for constructing high-performance functional media. However, paper-based filtration/adsorption materials integrated with metal–organic frameworks (MOFs) often suffer from porous-structure instability under airflow, weak interfacial anchoring, and heterogeneous MOF distribution, which together cause pressure-drop fluctuation, limited active-site utilization, and potential particle shedding. Herein, inspired by Da Vinci’s branching rule, we propose a branching-to-network design strategy enabled by moderate pulp refining to reconstruct cellulose fibers into a multiscale, hierarchically connected scaffold. Refining-induced microfibrillation transforms bundled fibers into a branched network with increased junction density and continuous load-transfer pathways, thereby stabilizing the porous architecture against airflow-induced deformation. Concurrently, microfibrillation exposes abundant hydroxyl-rich surfaces that strengthen interfacial anchoring with Co²⁺/MOF precursors and provide dense nucleation sites, enabling uniform in situ growth and robust immobilization of ZIF-67 throughout the fibrous network. Benefiting from the synergistic integration of a branching cellulose scaffold and uniformly distributed MOF functional nodes, the resulting ZIF-67@MFC composite paper achieves efficient formaldehyde capture (0.18 mg g⁻¹) and high fine-particulate removal efficiency (99%). Moreover, the biodegradable cellulose matrix, coupled with MOF-enabled structural disintegration, facilitates rapid degradation of the composite within 30 days in soil. Importantly, the entire fabrication route is fully compatible with conventional wet-end papermaking and can be readily scaled up using industrial equipment, providing a low-cost and sustainable platform for next-generation air-purification and personal-protective filtration materials.

Through a simple hydrothermal strategy, a strongly coupled g‑C 3 N 4 /Hf‑MOF heterojunction (CN/HUN) was successfully prepared, achieving efficient and selective photocatalytic CO 2 reduction to methanol without sacrificial agents. After reacting for 3 hours under simulated sunlight conditions without a sacrificial agent, the optimized CN/HUN 7 catalyst achieved a cumulative methanol yield of 520.48 μmol g -1 and a selectivity of 83%. Systematic characterization indicates that the strong interfacial interactions and electronic coupling between g-C 3 N 4 and Hf-MOF effectively accelerate charge separation, suppress carrier recombination, and significantly reduce charge transfer resistance. Furthermore, the Hf-MOF forms a Z-type heterojunction structure with g-C 3 N 4 , thereby enabling directed electron transfer. While electrons in the conduction band (CB) of the Hf-MOF are transferred to the valence band (VB) of g-C 3 N 4 , the unsaturated Hf 4+ sites may promote CO 2 adsorption and activation through Lewis acid-base interactions and are expected to stabilize key intermediates during the CO 2 reduction process, thereby enhancing the performance of CO 2 reduction to methanol. We demonstrate a viable route to construct tightly integrated MOF heterojunctions for high-performance photocatalytic CO 2 reduction to fuels.

As modern industry continues to develop rapidly, water pollution caused by antibiotics and synthetic dyes has become increasingly severe. To address the challenge of efficient treatment of such organic wastewater, a novel modified MIL-101(Fe) photocatalyst was constructed via a synergistic strategy of Cu²⁺ doping and in-situ polymerization of aniline. Under simulated solar irradiation, the composite photocatalyst achieved degradation efficiencies of 93.06% for tetracycline and 94.2% for methylene blue, exhibiting broad-spectrum photocatalytic activity toward various organic dyes. Cu²⁺ and PANI synergistically optimize the band structure, narrowing the bandgap to 2.23 eV while broadening the visible-light response range, promoting charge transport, and forming a stable Z-scheme heterojunction at the interface to suppress the recombination of photogenerated charge carriers. The results of reactive species trapping experiments showed that ·OH, h⁺, and ·O 2 - collectively governed the degradation process. The core mechanism stems from the ligand-to-metal charge transfer (LMCT) characteristics of MIL-101(Fe), the electron-trapping effect of Cu²⁺, and the conjugated conductive network of PANI. In addition, the composite photocatalyst exhibited strong resistance to ionic interference and maintained degradation efficiencies above 80% after five consecutive cycles, demonstrating excellent stability and reusability. This work provides an efficient photocatalytic material and a promising strategy for the comprehensive treatment of organic wastewater.

The simultaneous detection of acetaminophen (PA) and its toxic metabolite of 4-aminophenol (4-AP) is crucial for ensuring drug safety and controlling environmental risks. Here, a copper-based porous carbon nanocomposite (Cu/Cu 2 O@PC) derived from core-shell metal-organic frameworks (MOFs) with high conductivity, abundant catalytic sites and a stable porous structure were designed and synthesized through employing a controlled pyrolysis of a precursor with Cu 2 O as the core and CuZn-BTC as the shell, which served as the foundation for constructing a highly sensitive and selective electrochemical sensing platform for simultaneous determination of PA and 4-AP. The resulting sensor exhibited excellent analytical performance under optimized conditions, including wider linear ranges (0.10–300.00 μM for PA and 0.10–400.00 μM for 4-AP), lower detection limits (0.027 μM for PA and 0.015 μM for 4-AP), as well as good reproducibility and stability. And, satisfactory recovery were achieved for real samples analysis. This work not only provides an efficient and reliable analytical method for monitoring phenolic pollutants but also offers a new strategy for designing high-performance electrochemical sensing materials based on MOF-derived architectures.

To detect the degree of interaction between coptisine and different DNA G-quadruplexes (G4s) and screen its anti-cancer targets, this paper developed a highly sensitive fiber surface plasmon resonance (SPR) sensor using zirconium-based metal organic framework (MOF-808) nanomaterials and plastic coated multimode optical fiber, which solves the problems of background interference and low sensitivity in traditional fluorescence detection method. MOF-808 has the characteristic of high electron mobility, which increases the sensitivity of the sensor to 4869.03 nm/RIU and improves the performance by 107%. Meanwhile, thanks to the ultra-high specific surface area of MOF-808, coptisine is enriched on the sensor surface, providing more G4s binding sites, the detection limit for c-MYC Pu22 G4 is 11.15 nM. Three types of G4s were detected using the sensor, and the sensor showed a significant response to c-MYC Pu22 G4, indicating that coptisine has a strong targeting effect on Pu22 G4, which is consistent with the results of molecular docking simulation, confirming the effectiveness of the sensor as a drug target screening validation tool. This sensor exhibits good specificity, with no significant response to other substances such as double stranded DNA except for the substance being tested, and maintains excellent stability after long-term storage. This work provides a concept validation optical sensing platform for drug target screening.

This study develops MOF patches for controlled NO release in produce preservation. • MOF loading effectively protects NO donors from loss during wet-casting fabrication. • Three metal-node MOF patches enable differential NO release profiles. • Patch integrates moisture absorption, microorganism and respiration inhibition. • MOF patches significantly extend produce shelf life while reducing precursor loss. Nitric oxide (NO) preservation suffers from instability and safety issues via conventional single-exposure treatments, while wet-casting methods cause substantial NO donor loss. This study developed metal-organic framework (MOF)-mediated controlled-release patches to address these limitations. Three MOFs (Cu-MOF, Zn-MOF, Fe-MOF) with distinct pore structures were synthesized, achieving 26.9%–38.2% L-arginine loading. The resulting gelatin-polyacrylic acid sodium hydrogel patches exhibited tensile strength of 3.03–4.84 MPa and elongation at break of 131.3%–240.1%, and dissolution rates of 12.4%–17.2%. They also showed significant antimicrobial activity against E. coli, S. aureus, and A. niger . MOF loading elevated precursor utilization efficiency to 70%–82.5%. The patches achieved sustained release of H₂O₂ (8.0–9.6 mmol/g) and NO (41.7–50.6 ppm) over 12 days, extending cherry tomato shelf life to 12 days at room temperature while maintaining total bacterial levels within safe limits. This work establishes MOF-mediated controlled release for green preservative gas utilization. Download: Download high-res image (189KB) Download: Download full-size image

Green microwave-assisted synthesis of composite using methanol/water. • Natural diatomite support reduces cost and suppresses MOF-74(Ni) aggregation. • DRIFTS and Molecular Simulation reveal CO 2 binding at unsaturated Ni 2+ sites. • Life cycle assessment indicates potential net-negative CO₂ emissions. Developing cost-effective and efficient adsorbents is essential for practical CO 2 capture. Herein, a hierarchical MOF-74(Ni)/diatomite composite is prepared via a microwave-assisted in situ growth strategy, using natural diatomite as a low-cost porous support and a methanol/water system as a relatively benign solvent medium. Rapid crystallization is achieved at 100 °C within 20 min, providing an energy-efficient route for constructing mineral-supported MOF adsorbents. Structural characterization confirms the uniform anchoring of MOF-74(Ni) crystals on the porous diatomite scaffold without compromising the intrinsic crystallinity of the framework. The diatomite scaffold not only promotes the dispersion of MOF-74(Ni) but also constructs interconnected micro-/ meso -/macroporous transport channels, thereby enhancing gas diffusion and mass transfer. The optimized composite delivers a CO 2 uptake of 4.86 mmol·g −1 at 298 K and 1 bar, an IAST-predicted CO 2 /N 2 selectivity of 76, and a dynamic CO 2 capacity of 4.37 mmol·g −1 . It also retains over 97% of its initial capacity after 50 adsorption–desorption cycles and exhibits stable CO 2 uptake under humid and multicomponent simulated flue gas conditions. In situ DRIFTS and molecular simulations reveal that CO 2 adsorption occurs primarily at coordinatively unsaturated Ni 2+ sites through electrostatic interactions and weak coordination. ZLC analysis further confirms enhanced intraparticle diffusion and improved CO 2 desorption kinetics in the composite. Life cycle assessment estimates emissions of 308 kg CO 2 -eq per ton of CO 2 captured, indicating the potential for net-negative emissions and highlighting the promise of mineral-supported MOF adsorbents for sustainable carbon capture.
