Facing the current energy crisis, developing new green energy and advancing high-quality energy development are crucial, as multimetal sulfide semiconductors have great potential in photoenergy conversion. This study prepared a carbon-containing bimetallic phosphide (NiCoP@C) cocatalyst from a CoNi-based MOF, which was combined with ZnIn 2 S 4 (ZIS) hollow nanoflowers to enhance electrical conductivity and photocatalytic hydrogen production of the composite. XPS shows electron cloud density of ZIS increases in the composite via interfacial electronic reconstruction. FESEM reveals NiCoP@C nanoparticles are evenly anchored on surface and interlayer gaps of ZIS, forming a hierarchical heterostructure with more active sites. Performance tests show Z-NiCoP@C has a photocurrent density of 129.58 μA cm −2 (vs. 34 μA cm −2 of unmodified ZIS). Under 10 W visible light with 10% TEOA as a sacrificial agent, 10-h cumulative H 2 yield of the composite is 19.52 mmol g −1 , with a H 2 evolution rate of 1.95 mmol g −1 h −1 , 7.8-fold that of pristine ZIS (0.25 mmol g −1 h −1 ).

Lignin derivatives have attracted much attention because of their versatile applications across multiple fields. In this work, a group of bimetallic catalysts (Co 5 Ru 0 /C, Co 5 Ru 0.02 /C, Co 5 Ru 0.04 /C, Co 5 Ru 0.06 /C, Co 5 Ru 0.08 /C, Co 5 Ru 0.10 /C) were synthesized using a hydrothermal method and evaluated for the catalytic hydrodeoxygenation (HDO) of the lignin model compound vanillin to 2-methoxy-4-methylphenol. Among them, the Co 5 Ru 0.08 /C catalyst exhibited remarkable catalytic behavior, attaining 99.82% VAN conversion and 90.52% MMP selectivity under optimized conditions (200 ℃, 0 MPa N₂, 15 mL isopropanol, 4 h). Systematic study of CoRu bimetallic MOF-derived catalysts for the catalytic transfer hydrodeoxygenation (HDO) of vanillin under atmospheric pressure and without external H 2 , using isopropanol as a hydrogen donor. Characterization findings demonstrated that the boosted catalytic activity stems from the catalyst’s large specific surface area, well-developed mesoporous architecture, and abundant Lewis acid sites, which collectively facilitate reactant activation and promote reaction efficiency. Further density functional theory (DFT) calculations revealed that the bimetallic CoRu active sites possess more favorable adsorption energy than their monometallic Co cluster counterparts, corroborating the improved catalytic behavior. This work presents a promising paradigm for the design efficient bimetallic catalysts, which could provide a valuable reference for promoting the transformation of lignin into high-value-added chemicals.

The control of air humidity has become a critical challenge amid rapid industrialization and urbanization. Membrane-based dehumidification offers an energy-efficient alternative to conventional methods, yet its performance is often constrained by the inherent trade-off between permeability and selectivity. The mixed-matrix membranes (MMMs) incorporating nanofillers present a promising strategy to overcome this limitation. In this work, two hydrophilic aluminum-based metal-organic frameworks (Al-MOFs), CAU-23 and MIL-160, were incorporated into Pebax®1074 matrix to fabricate MMMs for air dehumidification. The introduction of hydrophilic Al-MOFs particles enlarges the inter-chain spacing in polymers and increases the fractional free volume (FFV), thereby enhancing water vapor permeability. Simultaneously, the nanochannels formed by the Al-MOFs provide preferential adsorption and transport pathways for water molecules, leading to markedly improved water vapor selectivity. Owing to its superior hydrophilicity, the MIL-160/Pebax membrane achieved higher H 2 O/N 2 separation performance (119 % up) than the CAU-23 counterpart (42 % up) relative to the pure counterpart. At an optimal loading of 5 wt%, the MMMs exhibited simultaneous improvements in both water vapor permeability and selectivity, this concurrent breakthrough underscores the strong potential of hydrophilic Al-based MOF MMMs for scalable application in industrial dehumidification processes.

Enzymatic biofuel cells (EBFCs) are green energy-conversion devices widely used in biosensing applications. However, unprotected enzyme is easily destabilised and may eventually deactivate under practical application scenarios. Thus, the activity of biological enzymes is constrained by their inherent fragility. Furthermore, in single-enzyme systems, the accumulation of intermediate products often inhibits enzymatic activity. Herein, we innovatively developed carbon dots (CDs) and cascade enzyme-glucose oxidase (GOx)/horseradish peroxidase (HRP) co-embedded hydrophilic MAF-7 biocatalyst (MAF-7@GOx-HRP/CDs). The MAF-7@GOx-HRP/CDs exhibit high electrocatalytic stability even under elevated temperatures and in the presence of molecular inhibitors. In real samples, devices employing the MAF-7@GOx-HRP/CDs bioanode achieved a 10-fold increase in power density (41.98 μW cm −2 vs 3.93 μW cm −2 ) compared with those using unprotected GOx-HRP/CDs. In addition, the developed biosensors demonstrated a linear detection range of 0.05–30 μM with a low detection limit of 0.04 μM. The sensor accuracy reached 98.4% when validated against the high-performance liquid chromatography (HPLC) method. This study demonstrates that integrating enzyme cascade systems into MOFs enhances biocatalytic activity, providing new insights for the development of advanced enzymatic catalysts for biosensing applications.

The separation of acetylene (C 2 H 2 ) from carbon dioxide (CO 2 ) and its subsequent storage remain formidable challenges in the petrochemical industry due to their nearly identical kinetic diameters and similar physical properties, which render conventional adsorption methods inefficient. Herein, we report an anion-pillared ultra-microporous metal–organic framework, Ni-TiF 6 -T4PP, engineered with tailored pore geometry and selective binding sites to achieve efficient C 2 H 2 /CO 2 separation. This material exhibits a high C 2 H 2 uptake of 3.99 mmol g −1 at 298 K and 1 bar. The pore environment, enriched with nitrogen and fluorine sites, promotes host–guest interactions with C 2 H 2 , resulting in a substantial differential in the isosteric heats of adsorption (Q st ): 36.04 kJ mol −1 for C 2 H 2 versus 19.35 kJ mol −1 for CO 2 . Combined with its low regeneration energy barrier, the framework can be readily regenerated, contributing to its recyclability. Breakthrough experiments demonstrate achieves separation performance for equimolar C 2 H 2 /CO 2 mixtures. At 353 K, a C 2 H 2 mixture with an initial concentration of 90% can be purified to achieve a final purity of > 99.2%. Based on the combined evidence from in situ infrared spectroscopy and molecular simulation, the underlying gas adsorption mechanism has been conclusively established that the extended π-surfaces of porphyrin and pyridine moieties enable multipoint cooperative binding with C 2 H 2 .

In the zinc ion capacitors (ZICs), Zn2+ storage is limited by the common carbon-based cathodes due to the sluggish kinetics of zinc ion diffusion. Porous carbon derived from metal–organic frameworks (MOFs) is a good candidate with the abundant micropores and mesopores. By using a one-step template-free solvothermal method, double-shell hollow Zn-MOF microspheres were directly synthesized, eliminating the traditional multistep activation process using KOH/HCl. During the carbonization procedure, urea has been used to provide an additional carbon source and activate the derived carbon, which is due to urea pyrolysis products, such as NH3, cyanuric acid, and ammelide. The derived porous carbon (U-MPC) exhibits a high specific surface area of 1695.66 m2 g–1. The ZIC device assembled with U-MPC as the cathode has a high specific capacitance of 199.0 F g–1 and a high energy density of 70.8 Wh kg–1 at 0.1 A g–1. The Zn//U-MPC ZICs demonstrate a good antiself-discharge performance, with a low self-discharge rate of only 3.1 mV h–1 over 300 h, and can maintain 59.7% of the initial capacitance. Moreover, the ZICs exhibit good cyclic stability, showing a slight decrease after 20,000 cycles at 5 A g–1, and the Coulombic efficiency is 90%.

Superoxide anion (O 2 •− ) plays a crucial role in various biological processes. However, its excess can induce oxidative stress, cause cell damage, and promote diseases. Achieving ultra-sensitive detection of O 2 •− remains a significant challenge. Herein, a nanocomposite that integrates two-dimensional (2D) CoNi metal-organic framework nanosheets (CoNi-MOF) aerogel with carbon nanofibers (CNFs) through robust interfacial interactions was designed and fabricated. This CoNi-MOF@CNFs nanocomposite is tailored for high-performance electrochemical sensing of O 2 •− . The 2D CoNi-MOF features a rich mesoporous structure, which provides a multitude of reactive active sites. Meanwhile, CNFs effectively accelerate the electron transfer rate. The synergistic interfacial interactions between CoNi-MOF and CNFs enable efficient collaborative catalysis of O 2 •− , significantly enhancing the electrochemical catalytic ability compared to each component individually. The CoNi-MOF@CNFs-based sensor exhibits a high sensitivity (341.97 µA µM − 1 cm − 2 ), a low detection limit (0.83 nM), and excellent stability (2400 s). More importantly, this fabricated sensor enables real-time monitoring of O 2 •− released by living cells, demonstrating its potential for disease diagnosis, highlighting the critical role of interfacial engineering in boosting the sensing performance of electrochemical sensors.

In this work, surface molecularly imprinted polymers Co-MOF/CNT@MIPs were prepared based on metal-organic framework (MOF) and muti-walled carbon nanotubes (MWCNTs) as matrix, and norfloxacin (NOR) as template molecular. The structural characteristics of molecular imprinted polymer Co-MOF/CNT@MIP were confirmed by Fourier transform infrared spectroscopy (FT-IR), scanning electron microscope (SEM), thermogravimetric analysis (TGA), Brunauer–Emmett–Teller (BET), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS). The adsorption and selective recognition performances of Co-MOF/CNT@MIP for NOR were also investigated. The adsorption of Co-MOF/CNT@MIP for NOR reaches equilibrium at 300 min, and pseudo-second-order (PSO) model is more fit for adsorption kinetic. The adsorption capacity of Co-MOF/CNT@MIP for NOR reaches 78.6 mg/g with 1.5 mg/mL at 25℃ via the hydrogen bond interaction and “lock-key” imprinted cavities, and the D-R model is fit for adsorption isotherm. The adsorption amount decreases as increasing the temperature, which is an exothermic and spontaneous process. The imprinted polymer exhibits an excellent imprinted factor of 2.08 and high selective factor above 1.93, and it is satisfactory reusability for five cycles.

Metal–organic frameworks (MOFs) and their derivatives have attracted extensive attention due to their multiple microwave attenuation mechanisms. However, challenges such as poor impedance matching and narrow absorption bandwidth still require further research and development. In this work, we propose an in-situ growth strategy to integrate MOFs with silicon carbide nanowires (SiC NWs) using dimethyldimethoxysilane as a molecular bridge. This strategy enables the fabrication of a novel heterostructure composite inspired by Pocky biscuits, consisting of MOF and SiC nanowires, with remarkably enhanced microwave absorption properties. The unique heterostructure not only preserves the excellent dielectric properties of SiC NWs but also incorporates FeCo magnetic nanoparticles and a conductive carbon network derived from MOFs, achieving superior impedance matching and multi-polarization loss. Calcined at 700 ℃, the MOF/SiC NWs composite exhibits an effective absorption bandwidth (EAB) of 6.18 GHz, covering the 11.82 to 18 GHz range that spans the entire Ku-band at a thickness of 2.1 mm. Furthermore, it achieves full-band absorption in the X-band at 2.9 mm. The performance enhancement is ascribed to the collaborative contribution of multiple mechanisms, including interfacial polarization, magnetic resonance, and conduction loss, as revealed by experimental and theoretical analyses. The findings herein open a feasible avenue for designing MOF-based absorbing materials with precisely adjustable electromagnetic properties.

Biocatalytic systems based on enzyme cascade reactions have attracted growing interest in the field of biocatalytic medicine. However, it is a major challenge to reasonably construct enzyme cascade reactions with high stability, selectivity, and catalytic efficiency for the in vivo biocatalytic application. Herein, two-in-one engineered glucose oxidase (GOx-Fe 0 ) is fabricated by a biomineralization strategy, through which a nanozyme (Fe 0 NP) is anchored within the inner cavity of GOx. Then, GOx-Fe 0 is immobilized in a pH-sensitive metal–organic framework (MOF) zeolitic imidazolate framework-8 (ZIF-8) to establish a stable and effective MOF-immobilized two-in-one engineered enzyme, GOx-Fe 0 @ZIF-8. In vitro studies show that GOx-Fe 0 @ZIF-8 exhibits excellent stability and high pH/glucose selectivity, and the shorter spacing between cascade enzymes can increase the cascade throughput and effectively improve the reaction efficiency of the enzyme cascade. In vivo experiments exhibit that GOx-Fe 0 @ZIF-8 solves the instability and systemic toxicity of free enzymes, and achieves deep tumor penetration and significant chemodynamic therapeutic efficacy through a pH/glucose-selective enzyme cascade reaction in tumor site. Taken together, such an orchestrated enzyme engineering strategy can effectively improve enzyme stability, selectivity, and enzyme cascade reaction efficiency via chemical transformations, and also provide a promising strategy for the application of biocatalytic cascade reactions in vivo.

A lanthanide terbium/europium metal–organic framework (Tb 0.6 Eu 0.4 -MOF) was prepared by one-step solvothermal method at room temperature. A series of characterizations including scanning electron microscopy, powder X-ray diffraction spectra, Fourier transform infrared spectra and X-ray photoelectron spectroscopy were carried out to clarify the physical characteristics of the synthesized material. The data clarified that the prepared Tb 0.6 Eu 0.4 -MOF possessed rod-like morphology with a width of 1–2 μm, and had good crystal structure, good stability, response speed and excitation-independent emission feature. The bunchy Tb 0.6 Eu 0.4 -MOF was then used to construct fluorescent sensors for rapid identification of malachite green and sulfamerazine. It was revealed that the detection mechanism was inner filter effect. The effects of different parameters such as excitation wavelength and incubation times were investigated on the fluorescence analysis performance. The data clarified that the optimal excitation wavelength and incubation time was 240 nm and 3 min, respectively. The detection platform exhibited the high sensitivity and selectivity toward malachite green in the linear range of 2–180 μM and determined limit of detection was 1.12 μM. Besides, the proposed sensor allowed sensitive detection of sulfamerazine in the linear range of 2–140 μM with a low detection limit of 0.1 μM. Meaningfully, a smartphone application was designed to assist the proposed sensor to realize visual, intelligent and rapid detection of malachite green and sulfamerazine. Furthermore, the practical application of the proposed sensor has been also verified by high performance liquid chromatography, showing good accuracy, sensitivity and satisfactory recoveries. The results suggested that the Tb 0.6 Eu 0.4 -MOF-based ratiometric fluorescent sensor had the potential to become a promising technique for rapid detection of malachite green or sulfamerazine with smartphone application. Therefore, the prepared Tb 0.6 Eu 0.4 -MOF is one kind of efficient and cost-effective potential materials for developing fluorescent sensor for rapid, sensitive and selective detection of sulfamerazine and malachite.

Artemisinin (ART) is a type of frontline drug to treat drug-resistant falciparum malaria. Simple, accurate and selective determination of ART is significant to monitor its clinical pharmaceutical efficacy. Herein, a new ratiometric fluorescence method has been designed for the determination of ART with Zn-MOF as fluorescence reference and hemin as catalyst, respectively. Zn-MOF possesses intrinsic fluorescence at 443 nm owing to 2-aminoterephthalic acid ligand. When o -phenylenediamine (OPD) is mixed with hemin, a weak fluorescent signal at 570 nm ascribed to oxidized product of OPD (oxOPD) is observed. In the presence of ART, hemin can catalyze ART to break its peroxide bridge and release a large number of reactive oxygen species, which effectively oxidize OPD into luminescent oxOPD. Therefore, the fluorescence at 570 nm is enhanced significantly while the fluorescence of Zn-MOF remains basically unchanged. Thus, a ratiometric fluorescence sensing platform has been constructed for the detection of ART. This method exhibits wider linear range (0.15 μM-150 μM) with detection limit of 50 nM. This novel and selective method has been used to detect ART in compound naphthoquinone phosphate tablets.
