Photoelectrochemical N 2 reduction reaction (PEC NRR) into chemical energy source is a promising technique for solving environmental challenges and the energy crisis, which depends on the exploration of p-type photocathodes. Cu 2 O is a p-type semiconductor, which can be applied as a photocathode for PEC NRR. However, the adsorption and activation ability of N 2 over the pristine Cu 2 O is still not ideal, causing the overall efficiency far below the theoretical value. In this work, we first proposed a feasible strategy to in-situ modify the surface of Cu 2 O with Cu-MOF, and the Cu-MOF/Cu 2 O heterostructure exhibited the significantly boosted NH 3 production rate (7.16 mmol/m 2 /h). The ultra-thin Cu-MOF film takes a nature of porous structure and unsaturated Cu sites, contributing to a favorable interface environment for the adsorption and activation of N 2 . The N 2 temperature programmed desorption and contrast photocurrent curves revealed the desirable selectivity for PEC NRR, and the isotope NMR further confirmed the accuracy of NH 3 evolution process. Therefore, the organic–inorganic hybrid systems built from Cu-MOF and Cu 2 O would offer a new insight for establishing the efficient PEC NRR system.

Tetracycline antibiotics (TCs) are widely distributed in the environment owing to excessive usage and incomplete metabolic breakdown, posing significant risks to ecosystems and human health. Herein, a bifunctional material, Cu-TATB-PCA, was prepared for simultaneous adsorption and detection of TCs. The material was constructed using Cu-MOF as the structural scaffold, with 1-pyrenecarboxylic acid (PCA) grafted via a postsynthetic ligand exchange (PSE) approach. The incorporated PCA moiety functions as both an active site for enhanced adsorption capacity and a fluorescent reporter for sensitive detection. Cu-TATB-PCA demonstrated a remarkable adsorption performance toward TCs, with a maximum adsorption capacity of 520.8 mg/g for oxytetracycline (OTC), 473.9 mg/g for chlortetracycline, and 469.5 mg/g for tetracycline (TC). The high adsorption capacity was mainly attributed to the dominant role of π-π interactions, which worked synergistically with coordination bonds, electrostatic interactions, and hydrogen bonds to collectively contribute to the adsorption process. In addition, Cu-TATB-PCA exhibited a highly sensitive fluorescent response toward TCs due to the mechanism of inner filter effect, which achieved a detection limit of 0.586 μM for TC and 0.776 μM for OTC. The streamlined and efficient material design paradigm paves the way for the development of bifunctional adsorption-detection materials and offers a promising avenue for future research endeavors in this field.

As living standards improve, the demand for food freshness has gradually increased. Multifunctional packaging materials that monitor food freshness in real-time, delay spoilage, and are environmentally friendly have emerged as ideal solutions. This study synthesized an ammonia-sensitive copper-based metal-organic framework (Cu-MOF) and incorporated it into a matrix composed of chitosan (CS) and gelatin (Gel). The resulting film exhibits ammonia-sensitive color-changing properties, antibacterial activity, and excellent biodegradability. The effects of Cu-MOF incorporation on the structural, physical, and functional properties of the CS/Gel films were systematically evaluated. Results demonstrated that the Cu-MOF was uniformly distributed within the CS/Gel matrix, significantly enhancing the mechanical properties (tensile strength increased by 68.49%), oxygen/water vapor barrier properties, and UV-blocking capability of the films. Notably, the CS/Gel@Cu-MOF films exhibited excellent antibacterial performance, with sterilization rates of 94.2% against Escherichia coli and 99.6% against Staphylococcus aureus . Additionally, the films showed good biocompatibility, biodegradability, and a sensitive color response to ammonia. The films were successfully used to monitor shrimp freshness through color change, transitioning from light green to brown as spoilage occurred. These findings indicate that CS/Gel@Cu-MOF films have significant potential for real-time visual freshness monitoring in food packaging, contributing to reduced food safety risks and waste.

Metal nanoparticles (MNPs)/metal–organic frameworks (MOFs) composites have become a research hotspot because the cooperation between MNPs and MOF can effectively improve the catalytic performance. However, development of a simple method to disperse the tiny MNPs on MOF is still a great challenge. In this work, a AuPdPt/Cu-MOF composite was prepared successfully by a one-step reduction process. First, Cu-MOF with one-dimensional nanorod structure was prepared by using surfactant PVP to control morphological growth. Second, the AuPdPt/Cu-MOF composite was synthesized by reducing the metal precursor to AuPdPt nanoparticles (NPs) supported on the surface of Cu-MOF. Encouragingly, synergistic effect between Au, Pd, and Pt, along with high dispersion of AuPdPt NPs on Cu-MOF nanorods, leading to excellent catalytic activities toward the benzyl alcohol with a conversion rate of 66%. Thus, this simple strategy to design promising MNPs/MOF composite can provide various opportunities in the field of catalysis.

In order to monitor and respond rapidly to outbreaks of food-borne pathogens, establishing rapid and sensitive detection methods is becoming increasingly urgent. In this work, through the synthesis of copper-based metal-organic framework nanoparticles (Cu-MOF NPs) and functionalized with aptamers, we developed a colorimetric protocol to detect Escherichia coli . In a typical experimental procedure, aptamer 1 was immobilized onto microplate to act as capture probes. Cu-MOF NPs were synthesized and functionalized with streptavidin and biotinylated aptamer 2 to form the signal probes. In the presence of E. coli , aptamers on both capture and signal probes bind with E. coli and form a sandwich-type complex. The Cu-MOF NPs enable to catalyze the colorless peroxidase substrate to yield a colorimetric output signal. This peroxidase-like mimics-based colorimetric aptasensor showed a rapid and sensitive quantification of E. coli in the concentration range of 16~1.6 × 10 6 cfu/mL with a limit of quantitation (LOQ) of 16 cfu/mL and limit of detection (LOD) of 2 cfu/mL. The application of the developed assay for colorimetric measuring of milk samples was evaluated with satisfactory results. The developed Cu-MOF NPs-assisted visual method can be expected as a powerful alternative and promising tool for foodborne pathogen detection and control.

The parasitic dinoflagellate in Hematodinium genus causes significant economic losses to fishery and aquaculture of multiple valuable marine crustaceans. It is practically needed to develop an effective and environmentally compatible method to control the Hematodinium epidemics in mariculture. In the present study, a novel Z-scheme composite photocatalyst was synthesized successfully using Zinc oxide (ZnO) and Copper Metal-Organic Framework (Cu-MOF), The N-Cu-MOF photocatalyst showed superior charge carrier separation efficiency compared to Cu-MOF, and exhibited significantly improved visible-light absorption in contrast to the activation of ZnO only under UV light. The ZnO/N-Cu-MOF photocatalyst demonstrated excellent inactivation of Hematodinium perezi microspores, with half maximal inhibitory concentration (IC 50 ) values of 3.12 mg/L at 1 h and 1.01 mg/L at 2 h. The inactivation effects involved the generation of large amounts of intracellular reactive oxygen species (ROS), which induced oxidative stress and disrupted the membrane and flagella structural integrity of the dinospores, ultimately leading to cell necrosis induced by oxidative damage. The present study provided a new insight and approach for seawater treatment of mariculture facilities, thereby to prevent and control spreading of Hematodinium epidemics in commercially valuable crustaceans.

Marine biofouling is one of the technical bottlenecks restricting the development of the global marine economy. Among the commercial self-polishing antifouling coatings, cuprous oxide is an irreplaceable component because of its efficiency and broad-spectrum antibacterial activity. However, one of the biggest obstacles to achieving long-term antifouling is the “initial burst and final decay” of cuprous oxide in the coating. Here, we lock the copper ions by establishing an antifouling unit composed of Cu2O (core) and Cu-based metal–organic framework (Cu-MOF, shell). Cu-MOF is densely grown in situ on the periphery of Cu2O by acid proton etching. The shell structure of Cu-MOF can effectively improve the stability of the internal Cu2O and thus achieve the stable and slow release of copper ions. Furthermore, Cu2O@Cu-MOF nanocapsules can also achieve active defense by rapid and complete dissolution of Cu2O@Cu-MOF at local acidic microenvironment (pH ≤ 5) where the adhesion of fouling organisms occurs. Super-resolution fluorescence microscopy is used to explain the sterilization mechanism. Relying on the water- and acid-sensitive properties of Cu-MOF shell, the stable, controlled and efficient release of copper ions has been achieved for the Cu2O@Cu-MOF nanocapsules in the self-polishing antifouling coatings. Thus, these controlled-release nanocapsules make long-term antifouling promising.

In this study, copper based metal organic frame work (Cu-MOF) was synthesized by using different solvents i. e. H 2 O, Dimethylformamide (DMF) and DMF + C 2 H 5 OH + H 2 O solutions at various temperatures. Cu-MOF synthesized in different solvents exhibited a large number of properties and advantages including easy synthesis procedure, high porosity, good crystallinity , high surface area, massive pore volume , controllable pore surface properties (zeta potential), rigid and chemical stability. The as-synthesized Cu- MOF was analysed by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), Scanning electron microscopy (SEM), Brunauer–Emmett–Teller (BET) surface area, zeta potential , electrostatic attraction and Thermal gravimetric analysis (TGA). A higher BET surface area of 121.1 m 2 g −1 was obtained for Cu-MOF synthesized in DMF + C 2 H 5 OH + H 2 O compared with H 2 O (109.3 m 2 g −1 ) and DMF (115.1 m 2 g −1 ) solvents. The as-obtained Cu-MOF was used to investigate adsorption kinetic performances of methylene blue (MB) and methyl orange (MO) dye molecules. Compared with other samples, Cu-MOF synthesized in (DMF + C 2 H 5 OH + H 2 O) has a significantly enhanced adsorption ability for MB but a lower for MO dyes. After 4 min, the adsorption co-efficient ( k) values were calculated to be 0.506, 0.846 and 1.1915 min −1 for MB and 0.029, 0.024 and 0.005 min −1 for MO dyes for Cu-MOF (H 2 O), Cu-MOF (DMF) and Cu-MOF (DMF + C 2 H 5 OH + H 2 O), respectively. It was found that Cu-MOF has a higher adsorption for MB dye but a poor adsorption capacity for MO, which was attributed to the electrostatic attraction/repulsion phenomena. Moreover, compared with Cu-MOF (DMF) and Cu-MOF (H 2 O), Cu-MOF (DMF + C 2 H 5 OH + H 2 O) shows an improved stability at 370, 417 and 423 °C temperatures. The result obtained through experiment suggested that porous Cu-MOF microstructures synthesized in DMF + C 2 H 5 OH + H 2 O have potential application for the treatment wastewaters having MB and MO dyes.

Limited by the notorious Li dendrites growth and serious polysulfide shuttle effect, the development of lithium-sulfur (Li-S) batteries is stagnant. Herein, a multifunctional separator composed of Cu-based metal-organic framework (Cu-MOF) and Li-Nafion was proposed to address the above intractable issues. The Cu-MOF with homogeneous porous structure and abundant Lewis acidic sites not only promotes uniform Li + flux, but also exhibits a strong chemical interaction with polysulfides to inhibit the shuttle effect. Moreover, the narrow pore size distribution in the Cu-MOF and negatively charged gap endowed by the -SO 3 − groups both act as ion sieve to facilitate the passage of Li + and restrict the migration of polysulfide anions, synergistically mitigating the dendritic Li growth and polysulfides shuttling. As a result, the symmetric cell with MOF/Nafion separator achieves ultralong cycling stability (1000 h) and ultralow overpotential of 20 mV at a current density of 1.0 mA cm −2 . Importantly, in the assembled Li-S full battery, the modified PP separator presents the superior cycle stability with capacity retention of 90% after 300 cycles at 0.5 C. Current outcomes open up a new route to design functional separators with ion permselective for realizing the dendrite-free and high-performance Li-S battery.

Drug-resistant bacterial infections pose a significant threat to global health, creating an urgent need for new antimicrobial agents. Reusing approved drugs has gained attention as a strategy to address this issue. In this study, a nano antibacterial platform (DSF@HKUST-1@Dex) that responds to the infection microenvironment is proposed. This platform releases disulfiram (DSF), binds to copper ions in the mildly acidic conditions of infected areas, converting DSF from nontoxic to toxic in situ, thereby inducing bacterial death and enhancing copper ion absorption. Noncatalytic treatment is also initiated for a synergistic antibacterial effect. Excessive copper ions disrupt bacterial metabolism, inhibit the Tricarboxylic acid (TCA) cycle, reduce ATP levels, and induce cuproptosis-like death, significantly enhancing antibacterial efficacy. In a bacterial wound infection model, the platform exhibited excellent antibacterial activity, promoting wound healing and reducing inflammation. Proteomic analysis showed that the platform selectively targeted bacterial peptidoglycan, disrupted the bacterial cell wall, impacted energy metabolism, and inhibited bacterial growth. In conclusion, this nanoplatform offers a promising strategy for treating drug-resistant infections by repurposing old drugs, converting them to toxic forms, and providing a novel antimicrobial approach.

Copper sulfides are proved to be good candidates as anode materials for sodium ion batteries due to their abundant resources, moderate cost, and relatively high electrical conductivity . However, poor rate performance and cycling life still hinder their development as anode materials for sodium-ion batteries. Herein, we synthesized carbon-coated copper sulfide nanorod assembled into octahedron composites (CuS x @C) by sulfuration of a Cu-based metal-organic framework (Cu-MOF) under different temperatures. These composites with hierarchical structure exhibited superstable cycling performance as anodes of sodium-ion batteries. The CuS x @C sample obtained under 500 °C showed discharge capacity of 208 mA h g - 1 at 2 A g - 1 over 6300 cycles. Porosity and hierarchical stucture facilitate the storage of sodium ion, and carbon-coated structure buffers volume change of anode materials during the electrochemical reaction .

This study presents the preparation of a novel electrochemical non-enzymatic sensor for the detection of glucose in natural saliva based on a metal organic framework (MOF) derivative (Cu-MOF-C) and nickel nanoparticle (NiNP) composite modified glassy carbon electrodes (GCE). The morphology and structural evolution were thoroughly characterized using scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), ultraviolet and visible spectrum (UV) and Fourier transform infrared spectrum (FTIR). Moreover, the electrocatalytic activity of the NiNPs/Cu-MOF-C/GCE for glucose was investigated using cyclic voltammetry (CV) and the amperometric i-t technique. The NiNPs/Cu-MOF-C/GCE sensor exhibits a wide linear range of 0.3–1150 μM and low detection limit (DL) of 0.090 μM at a signal/noise ratio (S/N) of 3. The average recovery rate of this method is satisfactory between 97.3% and 108.4%. Furthermore, the sensor exhibited excellent repeatability, good stability and reproducibility for glucose detection. Compared with traditional invasive measurement, the detection of glucose in natural saliva can reduce the pain caused by continuous blood collection, which is an ideal method for patients requiring continuous monitoring of glucose.
