The performance of hard carbon anodes in sodium-ion batteries is restricted by the inherent trade-off between rate capability and capacity due to uncoordinated ion-electron transport. This research indicates that the microstructure of the carbon host crucially determines the interfacial reconstruction behavior and electrochemical outcome of MOF modification. For porous cellulose-derived carbon, the integration of MOF induces a continuous composite interface, enhancing the Na + diffusion coefficient by an order of magnitude below 0.1 V (reaching 10 −9 cm 2 s −1 ), and yielding a high reversible capacity of 667.2 mAh g −1 with 79% capacity retention. In contrast, on commercial hard carbon with a higher degree of graphitization, MOF forms a discontinuous physical coating that obstructs intrinsic ion pathways, restricting rate performance of hard carbon despite the improvement in its cycling stability. In-situ EIS and distribution of relaxation time analyses disclose lower charge-transfer resistance and optimized SEI evolution in MOF@cellulose-derived carbon, facilitating efficient ion-electron dual transport. The full cell utilizing MOF@cellulose-derived carbon attains a high energy density of 172.8 Wh kg −1 at a power density of 2065 W kg −1 . This work offers mechanistic insights into the correlations among carbon microstructure, interface, and performance, guiding the rational anodes design of high-power and high-energy density sodium-ion batteries.

Co 3 O 4 is a promising electro-oxidation catalyst, which is applicable to the oxygen evolution reaction (OER) and glucose oxidation reaction (GOR). However, its insufficient active sites and poor conductivity severely restrict its practical application. Herein, a Co 3 O 4 /CN electrocatalyst derived from zeolitic imidazolate framework (ZIF)-67/CN was successfully synthesized via a solvent-free strategy for efficient OER and GOR. In electrocatalytic OER, Co 3 O 4 /CN demonstrated superior performance on a glassy carbon (GC) electrode, achieving an overpotential ( η ) of 306 mV at a current density ( j ) of 10 mA cm −2 , which outperformed Co 3 O 4 -ZIF (Co 3 O 4 /CN derived from ZIF-67). Furthermore, the Co 3 O 4 /CN electrocatalyst also exhibited good GOR ability, with high sensitivity of 1021.9 μA mM −1 cm −2 , a low detection limit of 1.8 μM ( S / N = 3), a broad linear range from 2 μM to 2.1 mM, excellent repeatability and reproducibility (relative standard deviation [RSD] < 6%), and long-term stability up to 3 weeks. The enhanced activity may be ascribed to the rich active sites, porous structure, and improved electrical conductivity of Co 3 O 4 /CN. This work provides a feasible strategy for enhancing electrocatalytic activity toward OER and GOR using metal–organic framework (MOF)/CN-based materials.

Catalytic transfer hydrogenation (CTH) of furfural to furfuryl alcohol is a pivotal strategy for valorizing biomass-derived platform molecules. Herein, we report the design of a yolk-shell MOF-808@hollow mesoporous silica spheres (MOF-808@HMSS) catalyst, where MOF-808 nanocrystals are uniformly confined within the internal cavities of HMSS. Compared to pure MOF-808, the spatial confinement effect imposed by HMSS induces the formation of smaller MOF-808 nanocrystals, increasing the density of accessible active sites. The mechanically robust HMSS shell significantly enhances the structural integrity of the catalyst by mitigating mechanical attrition and suppressing leaching of active components during reaction. Notably, the unique yolk-shell architecture creates a confined nanoscale microenvironment that promotes efficient adsorption and activation of reactants at catalytic centers. Consequently, MOF-808@HMSS exhibits markedly superior performance in CTH of furfural as well as higher reusability and cycling stability compared to pure MOF-808. Detailed characterization reveals abundant Lewis acid sites with a minor proportion of basic sites in MOF-808@HMSS. Selective poisoning experiments confirm that Lewis acid sites play a predominant role in the Meerwein-Ponndorf-Verley reaction, while synergistic interplay between acidic and basic sites enhances reactant adsorption and facilitates i -propanol deprotonation, collectively accelerating the overall CTH process.

The GD/MOF@3DE composite enabled pH-responsive release of Zn 2+ , Co 2+ , and 3DExos. • Zn 2+ and Co 2+ provided antibacterial/anti-inflammatory and antioxidant/pro-angiogenic effects, respectively. • Released 3DExos promoted M2 macrophage polarization and directly stimulated osteogenesis. • Transcriptomics revealed enhanced osteogenesis via ECM/HIF-1 pathway regulation. • The multifunctional coating promoted infected bone repair and implant integration in vivo . The compromised bone-implant interface microenvironment, regulated by oxidative stress, infection, inflammation, and disrupted bone homeostasis, remains the core challenge for effective titanium-bone integration. To address these issues, a composite hydrogel coating was fabricated on the titanium substrate, which consisted of a dual-network hydrogel based on a bimetallic metal-organic framework (Zn/Co-MOF) and incorporated gelatin methacryloyl-dialdehyde starch (GelMA-DAS, GD) co-loaded with human umbilical cord mesenchymal stem cell-derived three-dimensional exosomes (hUCMSC-3DExos, 3DE). The resulting GD/MOF@3DE coating exhibited infection-responsive (low-pH) behavior, enabling on-demand release of Zn, Co, and 3DExos. In vitro , the coated titanium effectively scavenged excess intracellular ROS and improved mitochondrial function. It also demonstrated potent anti-inflammatory activity by promoting macrophage polarization toward the M2 phenotype. The modified substrate showed excellent biocompatibility, broad-spectrum antibacterial efficacy against Gram-positive and Gram-negative pathogens, and significant upregulation of osteogenic markers. Transcriptomic analysis revealed that osteogenesis was promoted through regulation of key pathways, including extracellular matrix organization and HIF-1 signaling. Moreover, the coating displayed pronounced angiogenic and immunomodulatory osteogenic potential. Subcutaneous infection models and femoral defect repair experiments confirmed that this multifunctional coating possesses outstanding anti-infective, antioxidative, anti-inflammatory, angiogenic, and osseointegrative properties, offering an innovative strategy for modulating the postoperative microenvironment around orthopedic implants.

In response to the urgent public demand for food safety and ecological protection, the sensitive detection and efficient removal of glyphosate (GPS) are of paramount importance. Herein, a multifunctional aerogel (Ru@ZrMOFs@AG) based on agarose (AG) and multi-emissive metal organic frameworks was rationally designed to simultaneously achieve colorimetric-fluorescence dual-mode detection and high-efficiency removal of GPS. The fabricated Ru@ZrMOFs@AG aerogel exhibited exceptional adsorption performance towards GPS pesticides, with a maximum adsorption capacity reaching 133.87 mg/g, and maintained good reusability following five consecutive adsorption/desorption cycles. Particularly, this composite material is endowed with dual-emission fluorescent characteristics (with emission peaks at 450 nm and 600 nm), while simultaneously exhibiting remarkable peroxidase-like activity. In the presence of hydrogen peroxide, it efficiently catalyzes the oxidation of colorless o-phenylenediamine into yellow 2,3-diaminophenazine. Notably, upon introduction of GPS into the system, the fluorescence intensity of Ru@ZrMOFs@AG at 450 nm significantly increased, whereas the emission at 600 nm remained stable; concurrently, GPS markedly inhibited its peroxidase-mimicking activity, leading to a decrease in the system’s absorbance. This dual-mode sensor enabled ultra-trace quantification of GPS, with detection limits of 0.98 ng/mL and 2.11 ng/mL for the ratiometric fluorescence and colorimetric modalities, respectively. Therefore, the developed Ru@ZrMOFs@AG aerogels combine stable fluorometric and colorimetric performance, exceptional adsorption capacity, and facile recyclability, offering an economically efficient and environmentally friendly solution for the simultaneous removal and monitoring of GPS.

The in situ synthesis method is developed to chemically integrate dye@MOF systems with BNNS. • The SRh101@ZIF-BN composite retains excellent photoluminescent properties with a marked stability. • The resulting WLED exhibits superior performance and a notable 12.3 °C reduction in operating temperature. Dye@MOF composites show great potential for solid-state lighting, yet their practical deployment is hindered by insufficient stability. To address this challenge, we develop a red-emitting composite, SRh101@ZIF-BN, by in situ anchoring dye-incorporated MOFs onto ultrathin boron nitride nanosheets (BNNS).Systematic investigation of their microstructure, photoluminescence (PL) characteristics, and stability under various environmental conditions (ambient air, blue light irradiation, and elevated temperatures) confirms that the chemical integration of BNNS not only preserves the outstanding PL properties, but also significantly enhances photothermal stability, markedly outperforming physically blended BN additives. Finally, a high-performance white light-emitting diode (WLED) is fabricated by integrating the optimized SRh101@ZIF-BN composite with YAG:Ce 3+ phosphor on a 450 nm blue LED chip. The resulting device achieves excellent performance metrics: CIE color coordinates of (0.33, 0.33), a correlated color temperature (CCT) of 5096 K, an impressive color rendering index (CRI) of 91.1, and a luminous efficacy (LE) of 103.18 lm/W. Moreover, the operating temperature of the WLED is reduced by 12.3 °C compared to that based on the pristine SRh101@ZIF-8 phosphor. This work establishes an effective BNNS-stabilization strategy and opens a promising pathway for durable and efficient dye@MOF materials in advanced lighting applications.

The catalytic transfer hydrogenation (CTH) of furfural into furfuryl alcohol offers a promising route for the valorization of lignocellulosic biomass using liquid hydrogen donors instead of high-pressure H 2 . In this work, a defect-engineered MOF-801 catalyst with abundant Lewis acid sites was synthesized through a formic acid-regulated hydrothermal approach. Competitive coordination between formic acid and fumaric acid favors the nucleation and growth of MOF-801, and enhances the Lewis acidity of the catalyst. Characterization by FT-IR, XRD, SEM, and pyridine-IR confirmed the successful formation of MOF-801 with dominant Lewis acid centers. Using isopropanol as the hydrogen donor, the optimized reaction conditions (130°C, 2 h, 1.0 MPa N 2 ) achieved 99.5% furfural conversion and 94.4% furfuryl alcohol yield. Kinetic analysis demonstrated a first-order reaction with an apparent activation energy of 41.3 kJ·mol − 1 . The catalyst showed excellent recyclability and retained its crystallinity after five consecutive cycles. This study provides a simple and efficient method for constructing Lewis acidic MOFs with coordination unsaturated metal sites for biomass-derived CTH reactions, supporting an upgrading and transformation of platform molecules under hydrogen-free conditions. Graphical A defect-engineered MOF-801 catalyst with abundant Lewis acid sites is synthesized via formic acid modulation. The unsaturated Zr 4 + centers effectively activate both furfural and isopropanol, enabling efficient catalytic transfer hydrogenation to furfuryl alcohol under mild, hydrogen-free conditions with excellent recyclability.

BA@Ce-MOF exhibits SOD/CAT-like enzyme activities and antioxidant effects. • In situ formation of hydrogel via thiol-ene photo-click chemistry reaction. • The ROS-responsive oxidation of thioether bonds in the hydrogel network accelerates drug release. • Promotes osteogenesis, angiogenesis, and M2 macrophage polarization in vivo. The hyperglycemic and reactive oxygen species (ROS)-rich microenvironment in diabetes readily incites inflammation, and the persistent inflammation exacerbates bone resorption, severely hindering the repair of diabetic alveolar bone defects. The alendronate used in clinical practice can inhibit bone resorption but lacks osteoinductive activity and cannot modulate the inflammatory milieu; traditional Chinese medicine monomers possess anti-inflammatory potential but are limited by low bioavailability. Herein, we developed a multifunctional nanocomposite hydrogel via a hierarchical integration strategy using carbon dots and Ce-MOF nanozymes to promote diabetic alveolar bone repair. In this system, the Ce-MOF, exhibiting superoxide dismutase (SOD)-and catalase (CAT)-like activities, scavenges ROS and enables the sustained release of carbon dots composed of alendronate and baicalin, achieving synergistic antioxidant and antibacterial effects. The hydrogel, formed from vinyl-group-grafted chitosan and thiolated sodium alginate via rapid in situ photoclick chemistry, adapts to irregular defect shapes; the thioether bonds formed in its crosslinked structure enable ROS-triggered acceleration of BA@Ce-MOF nanoparticle release. In vitro, the BA@Ce@CSSA hydrogel demonstrated excellent biocompatibility. Its SOD/CAT activities and the antioxidant function of the monomer synergistically eliminated ROS and induced macrophage M2 polarization for immunomodulation. Concurrently, it enhanced osteogenic differentiation by upregulating RUNX2 and OPN expression. In vivo, Micro-CT and histomorphometric analyses confirmed that BA@Ce@CSSA significantly accelerated and improved the quality of bone regeneration. In summary, this study presents a hierarchically designed therapeutic strategy that effectively promotes bone regeneration by integrating antioxidant, anti-inflammatory, pro-angiogenic, and pro-osteogenic functions within a ROS-responsive hydrogel system, offering a promising approach for treating alveolar bone defects under diabetic conditions.

MOF-derived Fe-doped Ni 9 S 8 nanoparticles are uniformly anchored on N-rGO. • The synergistic effect at the heterointerface enhances electron transfer and active site exposure. • Fe 0.1 -Ni 9 S 8 /N-rGO achieves an overpotential of 255 mV at 50 mA cm −2 . • Fe doping shifts the d-band center down, weakening *O adsorption and lowering the RDS barrier. Developing effective, low-cost oxygen-evolution catalysts is essential for sustainable energy technologies. Here, we synthesized an N-doped reduced graphene oxide-supported, Fe-doped Ni 9 S 8 catalyst (Fe 0.1 -Ni 9 S 8 /N-rGO) by MOF-derived pyrolysis followed by sulfidation. To separate the effects of Fe-induced electronic modulation from N-rGO–assisted interfacial engineering, we prepared a series of control samples: Ni 9 S 8 , Ni 9 S 8 /N-rGO, Fe 0.1 -Ni 9 S 8 , and Fe 0.1 -Ni 9 S 8 /N-rGO. The optimized Fe 0.1 -Ni 9 S 8 /N-rGO exhibited efficient OER electrocatalysis, delivering 50 mA cm −2 at an overpotential of 255 mV with a Tafel slope of 54.58 mV dec −1 . Synergistic Fe doping and the Ni 9 S 8 /N-rGO heterojunction enhanced conductivity and increased active-site exposure, yielding higher activity. Electronic-structure analysis showed that Fe doping shifts the d-band center and tunes the interaction strength with key OER intermediates, which lowered the energy required for oxygen evolution. This work presents a logical strategy for designing high-performance, nonprecious-metal OER catalysts.

Pre-anchoring and alkali-regulated strategy constructs NiCo-LDH@NiFe 2 O 4 QDs heterostructure. • NiFe 2 O 4 quantum dots boost conductivity and structural stability of LDH. • Alkali source tuning modulates nanosheet morphology and ion diffusion. • The NiCo-LDH@QDs-K electrode delivers 2195.55 F·g -1 at 1 A·g -1 . • Asymmetric supercapacitor achieves 80.98 Wh·kg -1 , powers timer for 28 min. Layered double hydroxides (LDHs) derived from metal-organic frameworks (MOFs) possess high theoretical capacitance. However, their inherent low conductivity and structural instability during cycling limit practical applications. In this study, we propose an innovative pre-anchoring and directed conversion synthesis strategy for the rational synthesis of a tightly integrated NiCo-LDH with quantum dots (QDs) composite. Highly conductive NiFe 2 O 4 QDs were uniformly pre-anchored onto the surface of NiCo-BTC, followed by precise regulation of the alkalization process to in situ convert the precursor into LDH. Owing to the spatial confinement effect of the MOF precursor, aggregation of the quantum dots is effectively suppressed. Meanwhile, the in situ conversion process establishes strong interfacial coupling and efficient ion/electron transport pathways between the two components, thereby synergistically improving electrical conductivity, charge-transfer kinetics, and structural robustness.Benefiting from this unique structural design, the resulting composite exhibited outstanding electrochemical performance, achieving a specific capacitance of 987.99 C·g -1 at a current density of 1 A·g -1 . Furthermore, an asymmetric supercapacitor assembled with this composite as the positive electrode achieved an energy density of 80.98 Wh·kg -1 at a power density of 784.94 W·kg -1 and is capable of powering commercial electronic devices. This study provides an effective strategy for developing high-performance MOF-derived electrode materials through interfacial structural design.

Glycerol oxidation reaction (GOR) has garnered significant attention as a highly attractive reaction, extensively studied for its potential to replace the oxygen evolution reaction in overall water splitting with value-added chemicals production. However, inefficient C–H activation and poor intermediate conversion severely limit their activity and product selectivity. Herein, we develop a tiny high-entropy (HE) doping strategy to construct a Cu-, Zn-, and Mo-doped CoNi-based metal organic framework-derived catalyst (CuZnMo-MOF CoNi ) for glycerol electrooxidation. HE-effects induce the electronic structure modulation of CoNi active species and accelerate the conversion of intermediates during the GOR process. CuZnMo-MOF CoNi can achieve a current density of 10 mA cm −2 at 1.25V vs. RHE, and exhibited the highest formic acid Faradaic efficiency (92.4%) at 1.4 V vs. RHE, featuring better GOR performance compared with undoped counterparts. Moreover, the assembled membrane electrode assembly (MEA) demonstrated stable operation exceeding 120 h at a current density of 50 mA cm −2 , indicating its practical applicability. Our work establishes a tiny high-entropy doping strategy that synergistically regulates the electronic structure of active sites to optimize the reaction kinetics and selectivity during biomass electro-upgrading processes. Tiny high-entropy treatment induced electronic modulation of the catalytic Co/Ni sites in glycerol oxidation electrocatalyst, which optimizes glycerol adsorption and promotes selective C–H activation, leading to high Faradaic efficiency of formic acid (FA).

The Ni@SNC catalyst was prepared through a two-step pyrolysis-solvothermal method. • Sulfur species selectively etched amorphous carbon layers, exposing more active sites during doping. • Sulfur, as a doping atom, modulated the electronic structure of the active sites and enhanced the CO 2 RR performance. • The Ni@SNC catalyst achieved a maximum FE CO of 94.6%, with a current density of 13.4 mA cm -2 at this point. Utilizing renewable energy to catalyze the reduction of CO 2 into diverse high-value products represents an effective pathway for mitigating carbon emissions. Nickel-based catalysts benefit from natural abundance and low cost. Moreover, their CO 2 activation capability and *CO desorption characteristics can be optimized through rational structural design to modulate the adsorption energy of reaction intermediates. These properties make them viable alternatives to noble metal catalysts. In this study, a two-step method termed “pyrolysis-doping” was employed to synthesize the Ni@SNC catalyst, which consists of small-sized Ni nanoparticles supported on S N co-doped carbon, facilitating efficient electrocatalytic CO 2 reduction reaction (CO 2 RR). In the Ni@SNC structure, the coordination of surface Ni nanoparticles with N generates active sites, while S doping modulates the electronic state of these sites to optimize the adsorption of *COOH and the desorption of *CO. Performance tests indicated that Ni@SNC achieved a maximum CO Faradaic efficiency (FE CO ) of 94.6% at −0.9 V (vs. RHE), with a corresponding CO partial current density (j CO ) of 13.4 mA cm −2 , while exhibiting excellent stability during an extended electrolysis. Various characterizations and experiments have shown that S doping selectively etched the carbon layer, thereby increasing the electrochemically active area (ECSA). Furthermore, S doping modulated the electronic configuration of Ni N sites, enhancing the balance between adsorption and desorption of reaction intermediates. This work thus provides a new design method for creating efficient and stable non-precious metal CO 2 reduction catalysts. Download: Download high-res image (149KB) Download: Download full-size image
