TiO 2 has emerged as one of the most extensively studied photocatalysts, because of its great stability and abundant availability. The hydrogen production efficiency of TiO 2 photocatalysts can be significantly enhanced derived from the precursors of titanium-based metal-organic frameworks (MOFs) loaded with single-atom. Although the hydrogen evolution activity of TiO 2 -based photocatalysts under ultraviolet light has been steadily enhanced in recent years, the activity under visible light remains a critical challenge to be addressed. Herein, we report a Zn single atom (Zn SA) loaded TiO 2 -based photocatalyst derived from Ti-BPDC (Ti-MOF). Under irradiation with visible light at 400 nm, the optimized sample exhibits a hydrogen evolution rate (HER) of 9.21 mmol g −1 h −1 with an apparent quantum efficiency (AQE) of 6.82%, with a HER approximately 3 times higher than that of pristine TiO 2 (3.14 mmol g −1 h −1 ), along with great stability. The results demonstrate that loading an appropriate amount of Zn SAs optimizes the band structure of the photocatalyst, activates the adjacent O atoms, and also suppresses the recombination of photogenerated electron-hole pairs, as well as modulates the adsorption-desorption equilibrium of H∗ species, thereby significantly enhancing photocatalytic activity. This work offers a strategy for designing TiO 2 -based photocatalysts with high visible-light activity.

To date, most luminescence studies on MOF-76 have focused on tetragonal Tb 3+ -doped and Tb 3+ /Eu 3+ co-doped systems. In this work, MOF-76(Gd, Dy) and MOF-76(Gd, Tb, Dy, Eu) were synthesised for the first time and subsequently subjected to hydrothermal annealing in the presence of polyvinylpyrrolidone (PVP) as a dispersant. Annealing induced a tetragonal → monoclinic phase transition in MOF-76 and transformed the morphology from rods into highly crystalline, transparent nanosheets. As a result, the emission intensity of annealed MOF-76(Gd 0.98 , Dy 0.02 ) increased by approximately 25-fold and its photoluminescence quantum yield (PLQY) improved from 2.33% to 18.60%. These enhancements enabled the combination of hydrothermal annealing with a lanthanide co-doping strategy to achieve precisely tunable, highly luminescent colours in the multi-doped MOF-76(Gd, Tb, Dy, Eu) system. In the annealed materials ( a MOFs), efficient Tb 3+ → Dy 3+ and Dy 3+ → Eu 3+ energy transfer pathways were identified. Owing to their high luminescence and colour tunability, the resulting materials demonstrated practical applicability in colour-tunable fluorescent anti-counterfeiting and, when combined with N-CDs@starch, in white-light-emitting LED devices.

Diabetic wounds are characterized by persistent inflammation, impaired angiogenesis, and susceptibility to infection, posing significant clinical challenges. Here, we report an intelligent shape-memory sponge (P 1 A 3 @B-MOF) engineered for the programmable modulation of the diabetic wound microenvironment. The dressing consists of an interpenetrating network of oxidized pullulan and acellular dermal matrix, incorporating zeolitic imidazolate framework-8 (ZIF-8) metal–organic frameworks encapsulated with salvianolic acid B (SalB) via in situ self-assembly. This design enables exudate-triggered shape recovery and pH-responsive drug release, targeting the acidic pathological environment. We demonstrate that the released Zn 2+ and SalB exert synergistic effects: conferring broad-spectrum antibacterial activity, orchestrating macrophage repolarization from proinflammatory M1 to regenerative M2 phenotypes, and activating the hypoxia-inducible factor 1-alpha (Hif-1α)/vascular endothelial growth factor (VEGF) pathway to restore vascularization. In a diabetic rat model, the sponge accelerated wound closure with a 98.5% healing rate by day 14 and modulated collagen deposition via the transforming growth factor-β (TGF-β)/Smad signaling axis, thereby effectively mitigating scar formation. This integrated strategy offers a promising modality for restoring immune homeostasis and promoting functional skin regeneration.

This work describes the synthesis of a ZrP–C composite adsorbent using MOF-808 as a template via one-step, high-temperature carbonization. The adsorption performance of ZrP–C material toward fluoride ions was investigated as a function of time, solution concentration, temperature, pH, and coexisting anions. After 3 h, the ZrP–C-3 adsorbent achieved saturation in fluoride uptake, demonstrating a final uptake of 37 mg/g at equilibrium. Fit the adsorption process using kinetic and isothermal adsorption models. The study revealed that adsorption was dominated by monolayer chemical adsorption. Adsorption was found to be endothermic, according to thermodynamic studies, with higher temperatures favoring increased uptake. Combined XPS, XRD, and FT-IR studies revealed that ion exchange, surface complexation, and electrostatic interactions jointly governed fluoride removal. For low-concentration fluoride-containing water bodies, typically those with concentrations below 20 mg/L, adding an appropriate amount of adsorbent could effectively reduce the wastewater concentration to meet national standards. These results highlight the strong potential of ZrP–C-3 for practical applications in fluoride removal from wastewater.

In this study, a novel Cu-based metal−organic frameworks (Cu-MOFs) composite material was prepared, and used to develop a sensitive and efficient electrochemical ratiometric sensor for dopamine detection. Gold nanoparticles (NPs) and the conductive poly(xanthurenic acid) p(XA) were assembled on the Cu-tetrakis (4-carboxyphenyl) porphyrin (TCPP) surface by electrodeposition and cyclic voltammetry (CV) method, which greatly improved the electrocatalytic performance of the Cu-MOF modified electrode . Two substances (dopamine/DA, paracetamol/PA) with different electrochemical peaks were added to the electrolyte solutions , where DA was the analyte and PA was as a reference. The ratiometric value of differential pulse voltammetry (DPV) oxidation current (I DA /I PA ) linearly increased with the increasing concentration of DA with low detection limit. This electrochemical ratiometric approach based on the metal−organic framework composites is expected to be a valuable strategy for detection of other analytes.

Background Aluminum adjuvants remain the most widely used adjuvants in licensed vaccines. Their broader application, however, is restricted by local and systemic adverse effects and limited antigen compatibility, slowing vaccine development.Methods A nanoscale aluminum – fumarate metal – organic framework (AlFu‑MOF) was synthesized in water using Pluronic F127 and acetic acid. Based on this framework, a composite nanoadjuvant—(D)-mannose‑cTAT‑CpG@M@AlFu‑MOF (DCC@M@AlFu‑MOF) – was designed and characterized. The loading capacity for immunostimulatory cargos, including MSA‑2, CpG, cTAT, (D)-mannose, and OVA, was evaluated. Cellular uptake and immune activation of antigen‑presenting cells were tested in vitro. AlFu‑MOF displayed high loading efficiency and improved antigen availability. DCC@M@AlFu‑MOF promoted dendritic cell maturation and activation and also triggered the STING signaling pathway.Conclusion DCC@M@AlFu‑MOF is an aluminum‑based nanoadjuvant with potential dendritic cell‑targeting ability. It can coordinate innate immune signaling and shows promise for enhancing vaccine‑induced immune responses.

To obtain an excellent electromagnetic wave (EMW) absorption material, a strategy was proposed in this study with the aid of in-situ growth of carbon nanotubes (CNTs) on the surface of a metal–organic framework (MOF)-derived FeCoNiMnMg high-entropy alloy (HEA). The HEA@CNT composite was successfully prepared via a solvothermal method combined with a one-step pyrolysis process. With the pyrolysis temperature increasing from 600 °C to 800 °C, the length of CNTs grew from 200 nm to about 600 nm approximately, while the defect density of CNTs was enhanced. This structural evolution significantly improved the dielectric properties and impedance matching. Consequently, the sample prepared at 800 °C (HEA@CNT-800) exhibited outstanding microwave absorption performances, achieving a minimum reflection loss (RLmin) of −57.52 dB at a matched thickness of 2.3 mm and an effective absorption bandwidth (EAB) of 4.4 GHz at a thinner thickness of 1.9 mm. This work provides a novel perspective for designing high-performance MOF-derived absorption materials.

Metal–organic frameworks often lose CO 2 capacity in hot, humid flue gas because H 2 O competes for open metal sites (OMSs). Here we report a dual-stabilized, wood-based adsorbent in which Mg-MOF-74 is grown on an aminated wood sponge and overcoated with an ultrathin polydimethylsiloxane (PDMS) layer, coupling support immobilization with interfacial hydrophobization while preserving access to OMSs. Under flue-gas-relevant conditions (323 K, 50% RH), the material delivers a CO 2 uptake of 1.68 mmol·g −1 (≈89% of its dry-state capacity) and an IAST CO 2 /N 2 selectivity of 144 for a 50/50 mixture at 323 K. Humid-gas breakthrough tests confirm robust separation performance. Density functional theory (DFT) calculations attribute the humidity tolerance and selectivity to the synergy between accessible OMSs and PDMS-mediated interfacial polarity, without increasing the isosteric heat of adsorption, thereby enabling energy-efficient regeneration. The framework retains its crystallinity after 30 days of water immersion, and a techno-economic estimate projects a material cost of approximately US$10.36 kg −1 at a 1000 t·yr −1 scale. This scalable architecture reconciles capacity, selectivity, humidity resistance, and cost for post-combustion CO 2 capture.

Motivated by the demand for enhanced coating toughness and self-healing capabilities in polar low-temperature environments, a pH-responsive active filler, which was named as PDA@BTA@MOF, was synthesized through the layer-by-layer self-assembly of a metal–organic framework (MOF), benzotriazole (BTA) corrosion inhibitor molecules, and polydopamine (PDA). And then, the obtained fillers denoted as, was incorporated into an epoxy resin to prepare a composite coating (termed the PDA coating) that exhibited superior toughness and excellent low-temperature corrosion protection. Physicochemical characterization revealed that the PDA@BTA@MOF filler possesses a core-shell structure with cubic BTA@MOF as the core and PDA nanoparticles forming the shell, and the special structure ensure that the PDA@BTA@MOF filler could uniformly disperse within the PDA coating matrix. The active filler could significantly enhance the toughness, barrier properties against corrosive media penetration, and adhesion under various conditions of the PDA coating, primarily attributed to mechanisms such as the “pinning effect”. Electrochemical impedance spectroscopy (EIS) and salt spray tests reveals that the PDA coating containing PDA@BTA@MOF filler possesses more excellent anti-corrosion resistance that the pure epoxy coating (EP coating). Even under harsh alternating freeze-salt spray test conditions, where the diffusion of corrosive media through the is coating significantly accelerated and adhesion was substantially degraded, the PDA coating maintained remarkable protective efficacy. Furthermore, immersion tests and EIS analysis on scratched samples confirmed the pH-responsive release behavior of the PDA@BTA@MOF particles and the effective self-healing functionality of the PDA coating.

The fabrication of micro/nano metal oxide semiconductor (MOS) heterostructures, employing bimetallic metal–organic frameworks (Bi-MOFs) as self-sacrificing templates, can significantly enhance the sensitivity of the resulting nanocomposite materials. Herein, ZnO/NiO heterostructures derived from Ni/Zn Bi-MOFs were fabricated, which achieved outstanding UV-assisted NO 2 -sensing performance at room temperature. Our experiments reveal a sensitive dependence of the sensing performance of ZnO/NiO heterostructures sensor on calcination temperature. The ZnO/NiO-600 sensor, which was calcined at 600 °C, demonstrated the best sensing performance, achieving 3-fold sensitivity enhancement over pure ZnO. Under UV irradiation, the response value to 1 ppm NO 2 reaches 6.78, with corresponding response and recovery times of 15 s and 40 s, respectively. Furthermore, the ZnO/NiO-600 sensor exhibits an exceptional detection limit as low as 20 ppb and a strong linear response within the range of 20 ppb–1 ppm (R 2 = 0.994). The excellent sensing performance can be attributed to the synergistic effect of several factors, including the mesoporous structure of MOF-derived MOS materials, the formation of ZnO/NiO heterostructures, and UV irradiation. This work provides a promising strategy for the development of a novel Bi-MOF-derived MOS heterosturcture that can be applied to photoelectric gas sensor.

Driven by the increasing demands of flexible electronic devices operating in complex electromagnetic environments, the development of lightweight microwave absorbing materials with integrated flexibility, efficient absorption, and thermal stability is of great significance. Herein, a flexible silicon carbide nanofiber film (SZF) decorated with ZIF-8-derived nanoparticles is fabricated through electrospinning followed by high-temperature carbonization. Benefiting from the high aspect ratio and three-dimensional interconnected network of SiC nanofibers, the deformation stress can be effectively dissipated through fiber bending and sliding, endowing SZF with moderate mechanical flexibility. The 3D porous architecture enables incident electromagnetic waves to penetrate deeply into the SiC-based composite network, thereby promoting multiple scattering and reflection effects. Through a metal–organic framework (MOF)-derived strategy, abundant heterogeneous interfaces are introduced within the fibers, coupling the metal modification effect derived from ZIF-8 with the intrinsic dielectric properties and thermal stability of SiC. The ZIF-8-derived nanoparticles exhibit dimensions comparable to those of SiC nanofibers and are uniformly dispersed throughout the SiC matrix, reinforcing interfacial bonding and facilitating charge transport as well as multiple polarization relaxations. These synergistic effects optimize impedance matching and enhance electromagnetic attenuation through increased interfacial polarization and dielectric loss. Consequently, SZF demonstrates strong microwave absorption performance, achieving a minimum reflection loss (RLmin) of –56.29 dB at 12.58 GHz and an effective absorption bandwidth (EAB) of 5.38 GHz at a thickness of 2.5 mm. This study offers a viable strategy for designing lightweight materials that simultaneously feature flexibility, thermal robustness, and high-efficiency microwave absorption, holding great promise for advanced flexible electromagnetic protection systems.

Photocatalytic CO2 conversion into high-value-added products represents a promising approach to mitigating global energy demands and environmental problems. S-scheme heterojunctions hold significant potential for photocatalytic CO2 reduction owing to their efficient spatial charge separation and preserved strong redox capabilities, with the internal electric field (IEF) serving as the primary driving force for directional charge transfer. However, achieving precise and rational modulation of the IEF to further boost photocatalytic CO2 conversion efficiency remains a considerable challenge. Herein, we propose a crystal facet engineering strategy to finely tailor the IEF in S-scheme heterojunctions by employing metal−organic frameworks (MOFs) with well-defined exposed facets. A series of NH2-MIL-125@ZnIn2S4 (NM@ZIS) heterojunctions were constructed, and among them, the NM111@ZIS heterojunction interfaced exclusively with the (111) facet was demonstrated to possess the strongest IEF, as unambiguously verified by combined experimental characterization and density functional theory (DFT) calculations. This optimized charge configuration resulted in good photocatalytic CO2 reduction performance, yielding a CO evolution rate of 145.55 μmol·g−1·h−1, substantially outperforming counterparts with mixed or other facet orientations. This work provides a viable pathway for customizing the IEF in S-scheme heterojunctions through MOF crystal facet engineering, offering generalizable insights for the rational design of high-performance photocatalysts.
