Cu3(BTC)2 (H3BTC = 1,3,5-benzenetricarboxylic acid) was anchored onto the surface of carboxymethylated chitosan non-woven fabrics by a controllable layer-by-layer technique in alternating solution baths of Cu(OAc)2·H2O and H3BTC solutions, and the resulting [Cu3(BTC)2]n@chitosan non-woven fabric composite materials (n = number of alternate deposition cycles) were thoroughly characterized. The results showed that the composite materials not only exhibited excellent decontamination ability against sulfur mustard (HD), with an enhanced degradation rate of HD with increasing n, but also possessed remarkable haemostasis performance. The degradation efficiency of sulfur mustard by [Cu3(BTC)2]4@chitosan was found to be much higher than that of pristine [Cu3(BTC)2]4. The inherent haemostatic capabilities of the chitosan non-woven fabrics were not affected by the growth of Cu3(BTC)2 on the surface of chitosan. Oral and histological toxicity examinations of the pristine Cu3(BTC)2 sample showed that damage and toxicity in the viscera of mice was very low, even if the intra-gastric administration dose of Cu3(BTC)2 reached a very high level (50 mg of Cu3(BTC)2 per kg of mouse). The results have shown that the as-prepared composite can be used safely as a promising haemostatic decontaminant with good recyclability against sulfur mustard.

It is imperative to develop a rapid detection method for Hg2+ due to its harm to human health and the ecological environment. In this research, CuO/Au@Cu3(BTC)2 was synthesized through reducing HAuCl4 by CuxO@Cu3(BTC)2, which was obtained by reducing Cu3(BTC)2 with hydrazine hydrate. The oxidase-mimic activity of CuO/Au@Cu3(BTC)2 can be enhanced by Hg2+ through forming a Au–Hg alloy. Therefore, a colorimetric method was designed for Hg2+ detection with a linear relationship in the 0.05–25 μM range and a limit of detection of 9.7 nM. This strategy exhibited a strong selectivity to Hg2+ and was applied in a real water sample with reliable recoveries. This work provides a possibility for the rapid detection of Hg2+.

In situ interfacial growth of nanoparticles induced by the Pickering emulsion is a novel and convenient method for preparing hybrids/composites with specific tasks. For the first time, magnetic PMMA@Fe3O4/Cu3(BTC)2 hollow microspheres were produced by one-pot Pickering emulsion using Fe3O4 nanoparticle (NP) stabilizer. The Fe3O4 Pickering emulsion provided a large oil/water interface area for the in situ growth of Cu3(BTC)2 nanocrystals and further interfacial polymerization of polymethyl methacrylate (PMMA). The hollow hybrid microspheres showed synergetic multi-functions, including the magnetic separation property caused by Fe3O4 NPs, the reverse thermal expansion by PMMA, and the adsorption enhanced permeation by porous Cu3(BTC)2 NPs. When it was used as the drug carrier for ibuprofen, the good loading capacity and the controllable release duration confirmed its good properties. Moreover, all the realized synergetic advantages further reveled the potential promising applications of the interfacial synthesis by Pickering emulsion method.

The advancement of non-enzymatic glucose sensors is essential for enhancing the cost-effectiveness and continuous monitoring capabilities of glucose detection systems. Employing innovative materials and device structures constitute key strategies to achieve this objective. Herein, an in-situ growth method of laser-induced graphene (LIG) using dye-stained polyimide colloids formed films on various substrates was introduced. The cost-efficient, rapid, and portable glucose sensor was developed based on LIG patterned via direct laser writing (DLW), combining with a layer-by-layer growth method to deposit Cu 3 (HHTP) 2 (HHTP, 2,3,6,7,10,11-hexahydroxytriphenylene) onto the surface of LIG. By utilizing the first-principles density functional theory (DFT) calculations, the results shows that the LIG result in an upward shift of the d-band of Cu 3 (HHTP) 2 , hindering electrons from filling into the anti-bonding orbitals and improving the adsorption ability of the intermediate product on the surface, enhancing electrode catalytic activity. The glucose sensor has achieved a wide detection range (0.01–22 mM), a low detection limit (3 μM) and an excellent sensitivity (5276 μA mM −1 cm −2 ) in the low concentration range. This work provides novel insights into the growth of LIG on various substrates and offers a non-enzymatic sensor capable of accurate glucose measurements, while demonstrating exceptional reliability, stability and precision.

Propyl gallate (PG) as one of the most important additives has been widely used to prevent or slow the oxidation of foods in the food industry. In this work, Cu 3 (PO 4 ) 2 /BiVO 4 composite is synthesized through two hydrothermal processes. With visible light irradiation, the Cu 3 (PO 4 ) 2 /BiVO 4 composites modified PEC platform displays a superior anode photocurrent signal. The PEC sensor showed a wide linear range from 1 × 10 −10 to 1 × 10 −3 mol L −1 with a detection limit as low as 0.05 × 10 −10 mol L −1 . The Cu 3 (PO 4 ) 2 /BiVO 4 photoelectrochemical (PEC) sensor is designed and characterized by electrochemical impedance. Compared with GCE/BiVO 4 and GCE/Cu 3 (PO 4 ) 2 , the GCE/Cu 3 (PO 4 ) 2 /BiVO 4 has a higher photocurrent response. In addition, the sensor is highly selective for samples containing other antioxidants. Furthermore, the sensor can be used to detect PG in edible oil samples with satisfactory results. The recoveries of propyl gallate in edible oil ranged from 95.5 to 101.8%. The results show that Cu 3 (PO 4 ) 2 /BiVO 4 composites can be used to analyze PG in different edible oil samples, which are beneficial for food quality monitoring and reduce the risk of PG overuse in food.

Membrane fouling is a persistent and crippling challenge for oily wastewater treatment due to the high susceptibility of membranes to contamination. A feasible strategy is to design a robust and stable hydration layer on the membrane surface to prevent contaminates. A hydrogel illustrates a distinct category of materials with outstanding antifouling performance but is limited by its weak mechanical property. In this research, we report a reinforced hydrogel on a membrane by in situ growing ultrasmall hydrophilic Cu3(PO4)2 nanoparticles in a copper alginate (CuAlg) layer via metal-ion-coordination-mediated mineralization. The embeddedness of hydrophilic Cu3(PO4)2 nanoparticle with a size of 3–5 nm endows the CuAlg/Cu3(PO4)2 composite hydrogel with enhanced mechanical property as well as reinforced hydrate ability. The as-prepared CuAlg/Cu3(PO4)2 modified membrane exhibits a superior oil-repulsive property and achieves a nearly zero flux decline for separating surfactant stabilized oil-in-water emulsions with a high permeate flux up to ∼1330 L m–2 h–1 bar–1. Notably, it is capable of keeping similar permeate flux for both pure water and oil-in-water emulsions during filtration, which is superior to the currently reported membranes, indicating its super-antifouling properties.

H 2 O 2 sensor is widely used in biomedicine, environmental governance and food processing. However, it is limited by the complex preparation processes and high cost of raw materials. In this work, we develop a facile, simple and cost-effective method to fabricate H 2 O 2 sensor based on a screen-printed electrode via in-situ growth method. The copper was first electrodeposited on the working electrode of screen-printed electrode (SPE) as a sacrificial layer, subsequently, the SPE was immersed in horseradish peroxidase (HRP) containing phosphate buffer saline (PBS). The Cu ions formed by oxidation of the copper layer combined with HRP and phosphate ions to construct HRP-Cu 3 (PO 4 ) 2 hybrid nanoflowers on its surface. The fabrication process is straightforward, without complex reaction conditions and dangerous drugs, which is conducive to mass production. This sensor showed a good linear response to H 2 O 2 with a detection limit of 1.8 μM and a sensitivity of 263.3 μA∙mM −1 ∙cm −2 . Additionally, it possessed excellent selectivity and long-time stability. The performance of this sensor was investigated in various beverages such as milk, beer, and juice, showing reliable detection of H 2 O 2 which highlights the potential practical applications of the sensor.

The Fenton reaction is one of the most effective methods for treating organic wastewater, which is extremely harmful to humans but difficult to treat. However, finding simple, low-cost, and efficient catalysts for the Fenton reaction remains a challenge. In this study, a BSA-Cu 3 (PO 4 ) 2 hybrid nanoflower (NF) was synthesized to investigate its peroxidase-like activity for the treatment of organic wastewater. Its morphology, composition, and crystallization had been fully studied and the results confirmed that the NFs were successfully prepared. Subsequently, the origin of the peroxidase-like activity of the NFs was further analyzed, with the results suggesting two reasons: (i) the transformation between Cu(I) and Cu(II) and (ii) nano-effects. Additionally, Congo red was selected as the organic pollutant to simulate the decolorization of wastewater. After 3 h, the decolorization efficiency reached 96%. Furthermore, the NFs exhibited good storage performance, maintaining approximately 90% relative activity after storage for 30 days. In summary, the NFs have great application prospects in the treatment of organic wastewater. Graphical abstract

Membrane fouling is a key challenge to the sustainable operation of oil–water separation membranes. Constructing a stable hydration layer on the membrane surface as an oil-fouling resistance barrier by modulating the physicochemical structure of the membrane is one of the most effective strategies. Herein, inspired by the petal structure in nature, Cu 3 (PO 4 ) 2 and UiO-66-NH 2 particles were combined by a self-assembly strategy to construct CUP (Cu 3 (PO 4 ) 2 /UiO-66-NH 2 /PVA) composite membranes with anti-fouling capability against viscous crude oil. Benefiting from the petal structure and abundant polar groups within the membrane, the as-prepared membrane could easily combine with water molecules to form a stable hydration layer, which acted as a barrier to hinder the oil contamination of the membrane. Further, the hierarchical flower-like structure was conducive to the improvement of the emulsion breaking rate and permeation flux of oil-in-water emulsions. After 60 min continuous cross-flow separation, the obtained CUP composite membrane still remained prominent separation efficiency (99.6 %) and permeate flux (4685.96 LMH/bar). In addition, the CUP composite membranes showed outstanding resistance to acid and alkali as well as abrasion. This study provides an effective method for the advancement of high-performance membranes with high flux and anti-fouling capability in the flied of oily wastewater treatment.

Issues with separation and recycling of suspension powder samples in wastewater hinder the practical application of hybrid enzyme materials for environmental pollution control. In this work, for the first time, laccase–Cu3(PO4)2 hybrid microspheres with hierarchical structure were successfully prepared and loaded on a treated copper foil surface. First, Cu8(PO3OH)2(PO4)4·7H2O nanoflowers (CPN) were synthesized on the copper foil surface by a solution-growth method. Then the laccase–Cu3(PO4)2 hybrid microspheres were loaded on the CPN surface via an immersion reaction method using a laccase-containing phosphate buffer solution (PBS) solution. The formation mechanisms of CPN and La–CPN (laccase–Cu3(PO4)2 hybrid microspheres on the CPN surface) are discussed in detail and mainly contain the following processes: crystal growth, coordination effect, in situ growth, and self-assembly. Compared with free laccase, the as-obtained La–CPN has a higher decoloration efficiency (more than 95%) and decoloration rate (nearly 3.6 times higher than that of free laccase) on Congo red dye (CR) solution in the short time of 3 h. Cyclic voltammetry results demonstrated that the oxidizability of immobilized laccase could be enhanced as a result of the presence of Cu2+. Meanwhile, the utilization of the CPN carrier and the unique nanostructure gave the laccase–Cu3(PO4)2 hybrid microspheres high and stable decoloration efficiency and improved the tolerance toward pH and temperature changes. La–CPN still maintained about 85% relative activity after storage for 10 days. The concept presented herein can be further expanded to the preparation of other hybrid enzyme materials for environmental control, medical treatment, and more applications.

Graphical Cu catalyzed hydrogenation : An in situ hybridization of metal organic framework Cu 3 (BTC) 2 and titania route is constructed to acquire a highly dispersed and robust CuO#TiO 2 catalyst, which enables a superior high activity (∼20.8 mol FUR /mol Cu h) with sound furfural alcohol yield (>99 %) toward furfural hydrogenation. Production of value-added chemicals sourced from biomass platform molecules has tremendous significance for sustainable chemical engineering. Herein, we reported a successful fabrication of a highly dispersed copper nanoparticles catalyst, CuO#TiO 2 , via a facile route of in situ homogeneously hybridizing the metal organic framework Cu 3 (BTC) 2 with titania, and subsequent calcination. Distinctly from the copper catalysts prepared by the conventional routes (impregnation or co-precipitation), this novel CuO#TiO 2 catalyst has a small particle size (∼5 nm), easy-reducible copper species, and weakened Lewis's acidity. As a result, it shows superior high activity (∼20.8 mol FUR /mol Cu ⋅ h) as well as high furfural alcohol yield (>99 %) at 140 °C and 2 MPa for furfural hydrogenation. Moreover, the CuO#TiO 2 can be conveniently regenerated by calcination at 200 °C in the air, with no appreciable changes in its structure or activity, a test that we repeated 8 times. Through comprehensive structure characterizations, it has revealed a significant interaction between the CuO and TiO 2 originated from the in situ hybridization, which enables a bi-functional effect on the resulted CuO#TiO 2 catalyst: one is to generate more copper active sites by promoting the copper dispersion and reducibility; the other is to hinder the side reactions by decrease the support Lewis acidity. This work demonstrates a practical strategy to rationally design a highly efficient catalytic system in furfural hydrogenation catalysis.

Monitoring small amount of dopamine (DA) and acetaminophen (ACOP) in biological samples is of great significance for the early prevention of neurological diseases and safe use of medicines in clinical research. A novel electrochemical sensor based on conductive metal organic framework Cu 3 (HITP) 2 (HITP=2,3,6,7,10,11-hexaiminotriphenylene) and electrochemical reduced graphene oxide nanocomposite (denoted as Cu 3 (HITP) 2 /ERGO) was designed for simultaneous determination of DA and ACOP with enhanced sensitivity and selectivity. The Cu 3 (HITP) 2 /ERGO nanocomposite was characterized by scanning electron microcopy, energy dispersive spectroscopy and Fourier infrared spectroscopy. The oxidation potential separation of DA and ACOP achieved 226 mV. The Cu 3 (HITP) 2 /ERGO/GCE exhibited excellent electrochemical response towards the oxidation of DA and ACOP due to the superior conductivity and synergistic catalytic activity of Cu 3 (HITP) 2 /ERGO nanocomposite. The detection limits were 9 nM and 14 nM (S/N=3) for DA and ACOP with wide linear range of 0.05-150 μM and 0.1-100 μM, respectively. Furthermore, the proposed sensor has been successfully applied in the simultaneous detection of DA and ACOP in serum sample.
