Phthalocyanine (Pc) is a promising class of metalloantibiotics with antibacterial properties, akin to many metalloantibiotics, that exerts its effect by disrupting the bacterial respiratory chain. Therefore, it is particularly crucial to develop simple and efficient antibacterial strategies to enhance the activity of antibiotics. The construction of metal–organic frameworks (MOFs) helps to improve the electron transfer ability of phthalocyanine antibacterial drugs and enhance their antibacterial activity. In this study, we report the synthesis of a two-dimensional (2D) NiPc-Cu MOF using a modified liquid–liquid interfacial method, offering a facile, scalable, and stable approach. The excellent electron transfer properties of the MOF significantly enhance the ability of NiPc to disrupt the respiratory chain, thereby boosting its antibacterial activity. Compared to NiPc alone, NiPc-Cu MOF demonstrated a 1000-fold reduction in the minimum inhibitory concentration (MIC 50 ) against Escherichia coli ( E. coli ), reaching 4 ng/mL—a level surpassing most reported metalloantibiotics and comparable to clinically used antibiotics. Furthermore, NiPc-Cu MOF selectively targets bacteria with minimal cytotoxicity to animal cells. Based on this, we have developed NiPc-Cu MOF as a safe antibacterial coating for catheters, characterized by excellent stability and superior antibacterial activity. This study provides a straightforward and effective strategy for enhancing the activity of molecular drugs that exert antibacterial effects by interfering with the respiratory chain.

Room-temperature plasma-assisted catalysis represents an important pathway for CO 2 valorization. Rational design of catalysts tailored to plasma environment holds significant potential for improving catalytic efficiency. Unprecedentedly, we report a coordination-engineering strategy to fabricate the Fe/Cu mix-metal organic framework (Fe/Cu-MOF) catalysts for plasma-driven CO 2 dissociation into CO. Precise modulation during synthesis revealed an optimal Fe:Cu ratio of 0.44:0.56 to generating synergistic active sites favorable for CO production. The in situ-formed FeCu-based catalyst exhibited exceptionally high CO space-time yield of 32.3 mmol·gcat-1·h-1 under room-temperature plasma conditions. The coordination-tailored electronic structure enables the dynamic variations in the oxidation states of Fe/Cu upon plasma activation, thus facilitating sustained CO 2 activation. This work establishes atomic-level control of bimetallic sites as a powerful paradigm for plasma-catalytic systems. Graphical For the first time, Fe-Cu bimetallic metal-organic frameworks (MOFs) synthesized via a one‑pot solvothermal method were used for efficient decomposition of CO 2 into CO with excellent stability under nonthermal plasma (NTP). This integrated approach offers fundamental insights and technical support for the development of robust catalysts under plasma conditions.

The Cu-MOF’s susceptibility to easy hydrolysis impairs its utility. A one-pot method was used to encapsulate nanoporous hydrophobic Im-COF on the surface of Cu-MOF. The hybrid Cu-MOF@Im-COF exhibited a water contact angle (WCA) of 100.9°. Cu-MOF/G@Im-COF was obtained by a grooming process (G) with 1H,1H,2H,2H-perfluorooctanetriethoxysilane and integrated with epoxy resin (E51) in two ways. The Cu2+ release rate from the coatings, as determined by atomic absorption spectroscopy tests, was reduced to 0.01037 μg·cm–2·d–1. In antimicrobial experiments with E. coli, the killing time was extended for 12 h. The Bode value increased to 1.4 × 1010 Ω when immersed in a 3.5% NaCl solution for comparison. The self-cleaning and anti-icing test performance of the coatings was significantly improved with increasing WCA. Cu-MOF/G@Im-COF will have an even greater impact in more areas than just antimicrobial and corrosion resistance.

In this study, activated biochar (ABC) sourced from solid biowaste was prepared using wheat straw as the carbon source. The ABC was then used as a carrier for the in-situ growth of Cu-MOF-74, which was subsequently pyrolyzed at high temperatures to prepare Cu-MOF derivative-modified porous biochar composites Cu/ABC-T (T = 700–1000 °C) with a uniform distribution of Cu species on the biochar surface. The effect of pyrolysis temperature on the as-prepared Cu/ABC was investigated. The experimental results showed that Cu/ABC-900 exhibited the optimal adsorption performance for DBT, confirming that the uniform distribution of Cu on the biomass carbon surface after high-temperature pyrolysis effectively enhanced the desulfurization performance. Specifically, the as-prepared Cu/ABC-900 achieved an adsorption efficiency of nearly 90 % for 1000 ppm DBT, with an adsorption equilibrium time of only 5 min and a maximum adsorption capacity of 19.70 mg S·g −1 . The adsorption process of DBT by Cu/ABC followed the pseudo-second-order kinetic model and Langmuir adsorption model. The adsorption performance of Cu/ABC-900 for different sulfides followed the order: DBT > BT > TH. Furthermore, the adsorption efficiency of Cu/ABC-900 for DBT did not exhibit any significant decline after five regeneration cycles, indicating the excellent regenerability and great potential for practical applications. This work provides a new approach to utilizing carbon-based adsorbents for deep desulfurization, which is beneficial for cost-effective fuel cleaning.

The construction of metal–organic frameworks (MOFs) with desirable structures for high-performance photocatalysis is attractive but remains challenging. Here, a hierarchically meso- and microporous sc Cu-MOF-74 was synthesized in supercritical CO 2 ( sc CO 2 )/methanol solution. Compared with the conventional microporous Cu-MOF-74, the meso- and microporous sc Cu-MOF-74 has more exposed and accessible Lewis acid sites derived from the missing-linker defects. The unique structure endows sc Cu-MOF-74 with superior molecular accessibility, enhanced separation, and transfer efficiency of photogenerated charges. High catalytic activity and reusability can be achieved in photo-oxidative coupling of amines, reaching a maximum N-benzylbenzaldimine yield rate of 4.80 mmol g −1 h −1 under mild conditions, that is, air atmosphere and room temperature. This study provides a new idea for improving the intrinsic photocatalytic activities of MOFs.

A non-enzymatic electrochemical sensor for glucose detection is executed by using a conductive metal–organic framework (MOF) Cu-MOF, which is built from the 2,3,6,7,10,11-hexahydroxytriphenylene (HHTP) ligand and copper acetate by hydrothermal reaction. The Cu-MOF demonstrates superior electrocatalytic activity for glucose oxidation under alkaline pH conditions. As an excellent non-enzymatic sensor, the Cu-MOF grown on Cu foam (Cu-MOF/CF) displays an ultra-low detection limit of 0.076 μM through a wide concentration range (0.001–0.95 mM) and a strong sensitivity of 30,030 mA μM−1 cm−2. Overall, the Cu-MOF/CF exhibits a low detection limit, high selectivity, excellent stability, fast response time, and good practical application feasibility for glucose detection and can promote the development of MOF materials in the field of electrochemical sensors.

In this study, a colorimetric detection system for Cr(III) was established by leveraging the laccase-mimicking activity of two-dimensional Cu-based metal-organic frameworks (Cu-MOFs) modified with polydopamine (PDA) nanomaterials (Cu-MOF@PDA), through which Cr(III) specifically inhibits the catalytic performance. The Cu-MOF@PDA composite exhibited significant laccase-mimicking activity, enabling the oxidation of 2,4-dichlorophenol (2,4-DP) and 4-aminoantipyrine (4-AP), leading to the generation of a red-colored compound. Notably, the laccase-like activity of Cu-MOF@PDA was substantially enhanced under ultrasonic (US) stimulation. Free-radical trapping experiments revealed that the levels of singlet oxygen ( 1 O 2 ) and hydroxyl radicals ( OH) were markedly increased, while the electron transfer rate was accelerated, thereby boosting catalytic efficiency under US exposure. The research confirmed that Cr(III) binds to Cu-MOF@PDA, leading to the suppression of its catalytic activity. A strong linear correlation (R 2 = 0.995) was observed between the absorbance at 505 nm and Cr(III) concentrations ranging from 0.67 to 54.17 μg/L, with a low detection limit (LOD) of 0.26 μg/L (S/N = 3). The developed approach was effectively utilized for the analysis of Cr(III) and total Cr in cigarette tipping paper samples, yielding highly satisfactory results.

Poly(ethylene oxide) (PEO)-based electrolytes have been extensively studied for all-solid-state lithium-metal batteries due to their excellent film-forming capabilities and low cost. However, the limited ionic conductivity and poor mechanical strength of the PEO-based electrolytes cannot prevent the growth of undesirable lithium dendrites, leading to the failure of batteries. Metal–organic frameworks (MOFs) are functional materials with a periodic porous structure that can improve the electrochemical performance of PEO-based electrolytes. However, the enhancement effect of MOFs with different metal centers and the interaction mechanism with PEO remain unclear. Herein, MOF-74s with Cu or Ni centers are prepared and used as fillers of PEO-based electrolytes. Adding 15 wt % of Cu-MOF-74 to the PEO-based electrolyte (15%Cu-MOF/P–Li) effectively improves the ionic conductivity, lithium transference number, and mechanical strength of the PEO-based electrolyte simultaneously. Furthermore, the ordered pore channels of Cu-MOF-74 provide uniform Li-ion transport pathways, facilitating homogeneous Li+ deposition. As a result, the lithium symmetric cell with 15%Cu-MOF/P–Li shows stable cycles for 1080 h at 0.1 mA cm–2 and 0.1 mAh cm–2, and the Li | 15% Cu-MOF/P–Li | LFP full cell exhibits a long cycle life up to 200 cycles at 60 °C and 0.5 C, with a capacity retention rate of 89.7%.

A novel all-in-one electrochromic device from viologen-based Cu-MOF was demonstrated successfully for the first time. The viologen-based Cu-MOF was dispersed in a photochemical eutectic solvent and directly used as an electrochromic material with the outstanding advantage of good modulation ability in a wide range of visible light. The electrochromic device's (ECD) color changed from transparent and light lime green to blue during the change of potential from 0 V to −3.5 V. The bistability of the ECD was demonstrated by the transmittance degradation of less than 10 % over 1.79 h when the power was turned off. This showed that the ECD could maintain its optical state long without a continuous power supply.

The misuse of antibiotics leads to the emergence of a variety of drug-resistant bacteria, which poses a serious threat to human life. Novel antimicrobial strategies are urgently needed. Herein, peroxidase-like enzyme material of Cu 2 O/NPC/Pal was prepared from Cu 2 O/nanoporous carbon (Cu 2 O/NPC) derived from Cu-MOF in the presence of palygorskite (Pal) by the pyrolysis-etching-pyrolysis strategy. Cu 2 O/NPC/Pal could catalyze the production of ·O 2 − from H 2 O 2 to cause the oxidative stress and cell membrane damage to bacteria. The antibacterial rates against Staphylococcus aureus and Pseudomonas aeruginosa reached 98.99 % and 92.70 %, respectively. In addition, Cu 2 O/NPC/Pal can promote the oxidation of glutathione and the consumption of intracellular effectively. Introduction of Pal into Cu 2 O/NPC significantly enhances the binding affinity and forms a highly concentrated substrate microenvironment. The study provided the pyrolysis strategy for the synthesis of carbon-based metal oxide nanomaterials in combination with mineral-based materials for the enhancement of peroxide-like activity in antimicrobial application.

A copper metal-organic framework composite nanozyme (Cu-MOF) with peroxidase-like activity was prepared using an improved room temperature method. Cu-MOF can catalyze H 2 O 2 to release (•OH), thereby oxidizing the colorless chromogenic substrate 3,3′,5,5′-tetramethylbenzidine (TMB) into a blue oxidized product (oxTMB), which has a maximum UV absorption peak at 652 nm. Nicosulfuron can regulate the electronic balance of the redox pair (Cu 2+ /Cu + ) on the Cu-MOF surface, thereby enhancing its peroxidase activity and promoting the deepening of the TMB blue color. Based on this principle, a colorimetric detection method for nicosulfuron was established. The linear range of this method is 0.2–10 μg/mL −1 , and the detection limit is 0.02 mg/kg. This method has been applied for the detection of nicosulfuronin corn samples, with recovery rate ranging from 90.88% to 117.33%, and all relative standard deviation being less than 4%.

In this paper, a heart-shaped nanocomposite (MXenen@Cu-MOF, MC) has been prepared by hydrothermal method . This material can effectively prevent the accumulation of MXene , improve the material's electrical conductivity and antibacterial properties. In addition, it is loaded into Polyvinyl alcohol/Poly-dopamine hydrogel wound dressings (PPMC), which can effectively destroy bacterial biofilms and provide a new pathway for internal electrical currents, helping to repair internal electric fields and promote wound healing. Through the concentration gradient experiments of hydrogel such as antibacterial, conductive, hemolysis and cell migration, we believe that the addition of MC can improve the basic properties of hydrogel. Among them, PPMC0.2 is the hydrogel with the best performance under the premise of meeting bio-compatibility. Its resistance, between 500 and 1000 Ω, is lower than the skin resistance at the wound site and provides the basis for the passage of current through the body. In addition, the cell mobility (24h) of PPMC0.2 reached 58%, and the wound healing rate (6day) was 81.84%, which was much higher than that of other experimental groups. The experimental results proved that PPMC hydrogel can promote wound healing, and this study also provided a new therapeutic idea for chronic wound healing.
