Water scarcity and water pollution are two major environmental issues facing all over the world. Membrane technology is an efficient and advanced wastewater treatment technology that has unique advantages in removing particulate matter, organic matter, microorganisms, and other pollutants. The present work report a high performance nanofiltration membrane for recycling and utilization of energy resources. The membrane was prepared by co-deposition dopamine and PEI in the PES based membrane as the intermediate layer, then spraying with different content of MOF-801. Subsequently, interfacial polymerization was carried out through piperazine and 1,3,5-benzenetricarbonyl trichloride. The obtained membrane was evaluated by testing the separation performance of Na 2 SO 4 , MgSO 4 , MgCl 2 and NaCl aqueous solution. FTIR, CA, XPS, SEM, AFM were carried out to analysis the physical and chemical structures of membranes. The effects of dopamine co deposition, nanomaterial content, salt type, stability and anti-pollution were investigated. Results shown that the membrane exhibits excellent water flux and rejection after modified with MOF-801. The addition of 2% nanofiller could achieve the optimum performance. The water flux for Na 2 SO 4 , MgSO 4 , MgCl 2 and NaCl were 21.19 L m −2 h −1 bar −1 , 21.11 L m −2 h −1 bar −1 , 22.18 L m −2 h −1 bar −1 , 25.74 L m −2 h −1 bar −1 , respectively. The membrane present great stability for the continuous test of 70 h. Additionally, the performance of membrane maintain a high water flux after three rounds of pollution and cleaning. This is the first time that MOF-801 has been used as an intermediate layer to prepare nanofiltration membranes, which providing new route for the preparation of high performance membrane.

Accurate and sensitive detection of pesticide residues is crucial for environmental safety and human health. Herein, a self-powered metal–organic framework nanozyme-based immunoassay was developed for selective and sensitive detection of isoprocarb by encapsulating calcium peroxide and heme into a Zn-MOF to construct the CaO2/heme@Zn-MOF composite. The prepared nanozyme exhibits intrinsic peroxidase-like activity and enables in situ H2O2 generation under acidic conditions, effectively eliminating the need for external oxidants. By coupling antibody–antigen specific recognition with catalytic signal amplification of CaO2/heme@Zn-MOF, a competitive nanozyme-linked immunosorbent assay was established for selective detection of isoprocarb. The fluorescence signal originating from o-phenylenediamine oxidation gradually decreases with an increase in isoprocarb concentration, allowing quantitative analysis with a detection limit of 0.017 μM. The entire competitive immunoassay can be completed within an optimal detection time of 90 min. Furthermore, the proposed method demonstrates excellent practical reliability and anti-interference capability in real water and agricultural products, achieving quantitative recovery rates ranging from 92.85% to 107.14% with relative standard deviations of less than 5.91%. Furthermore, a portable immunomagnetic bead with paper devices was fabricated for on-site analysis. This work provides a general strategy for integrating self-powered nanozymes with immunoassays, thereby expanding their potential for portable environmental monitoring.

In-situ growth of Ti-MOF@rGO improves dispersion, reduces agglomeration, and facilitates electron transport. • 0.3–400 μM linear range, 0.114 μM LOD (S/N=3), selective vs UA/AA, stable/reproducible. • Synergistic Ti-MOF@rGO boosts DA adsorption and electron transfer via 2e - /2H + redox. Electrochemical detection of dopamine (DA) is critically important for the diagnosis and monitoring of neurological disorders. In this study, we present a novel composite material, Ti-MOF@rGO, synthesized in-situ through the integration of titanium-based metal-organic frameworks (Ti-MOFs) with reduced graphene oxide (rGO). This hybrid material effectively combines the abundant redox-active sites of Ti-MOF with the excellent electrical conductivity and large specific surface area of rGO, thereby facilitating efficient charge transfer and enhanced DA adsorption. The Ti-MOF@10%rGO-modified glassy carbon electrode demonstrated outstanding electrocatalytic performance for DA oxidation, exhibiting a wide linear detection range of 0.3–400 μM and a low detection limit of 0.114 μM (S/N = 3). The sensor exhibited high selectivity against common interferents such as uric acid and ascorbic acid, along with excellent repeatability, reproducibility, and cycling stability. This work presents a promising strategy for the rational design of MOF-based composites and offers a robust platform for ultrasensitive and selective electrochemical biosensing applications.

en This link goes to a English section zh This link goes to a Chinese section A facile coprecipitation-pyrolysis strategy was employed to fabricate Cu/Co nanoparticles (NPs) embedded in nitrogen-doped carbon matrices (Cu/Co@N-C) through the carbonization of CuCo-MOF precursors. Moreover, monometallic counterparts of Cu@N-C and Co@N-C were also prepared via carbonization of bimetallic CuZn-MOF and CoZn-MOF, respectively. Electrochemical tests confirm that Cu acts as the key active center for nitrite oxidation. By adjusting the Cu/Co molar ratios, a series of cubic Cu/Co@N-C composites with tunable sizes of 200–500 nm were achieved. The synergistic interaction between metallic Cu/Co NPs and the conductive N-C framework enhances catalytic activity and reduces overpotential compared to the monometallic Cu counterpart. The optimized Cu/Co@N-C/glass carbon electrode (GCE) sensor delivered a superior sensitivity as high as 0.461 μA μM −1 cm −2 and wide detection range of 2–10000 μM. The Cu/Co@N-C/GCE sensor also demonstrated superior selectivity, long-term stability of 92.5% retention after 21 days, and reproducibility. This work establishes a versatile approach for engineering various MOF-based catalysts, demonstrating promising potential for applications in environmental monitoring and food safety analysis. 摘要 en This link goes to a English section zh This link goes to a Chinese section 采用一种简便的共沉淀–热解策略 , 以 CuCo-MOF 前驱体为碳源进行碳化 , 成功制备了氮掺杂碳基质负载的 CuCo 双金属纳米颗粒复合材料(Cu/Co@N-C)。此外 , 还分别基于双金属CuZn- MOF和CoZn-MOF碳化制备了Cu@N-C和Co@N-C。电化学测试表明Cu是亚硝酸盐氧化的关键活性中心。通过调控 Cu/Co 摩尔比 , 获得了粒径可调、尺寸范围为 200–500 nm 的立方体 Cu/Co@N-C 复合材料。与单金属Cu@N-C相比 , 金属Cu/Co NPs与导电N-C框架之间的协同作用增强了催化活性并降低了过电位。优化后的 Cu/Co@N-C/玻碳电极(GCE) 传感器表现出优异的电化学传感性能 , 其灵敏度高达 0.461 μA μM −1 cm −2 , 检测范围宽达 2–10000 μM。Cu/Co@N-C/GCE 传感器还展现出优异的选择性、良好的重复性以及长期稳定性 , 在存放21天后仍可保持 92.5% 的电流响应。该工作为构筑各种MOF 基催化材料提供了一种通用策略 , 显示出其在环境监测与食品安全分析领域的广阔应用前景。

The continuous contamination of ciprofloxacin (CIP) pharmaceutical residues poses a potential risk to the ecological environment and human health. Using semiconductor materials with optimized heterojunctions for photodegradation is an effective way for the CIP removal. In this study, Fe-ZnO/CdS Z-type heterojunction was synthesized, and used for the photodegradation of organic pollutants. The Fe-doping brought abundant surface oxygen vacancies to ZnO, which could effectively promote interfacial electron transfer. In addition, the valence transition of Fe (II)/Fe (III) could effectively participate in the redox cycle and improve the carrier transfer efficiency. The construction of Z-type heterojunction facilitated the separation of photogenerated carriers, and the photogenerated electrons in the conduction band of CdS reduced oxygen to produce superoxide radicals as the main active radicals. A series of photoelectric characterizations had proved that the introduction of CdS could effectively improve the visible light utilization rate and photogenerated carrier separation efficiency. The Fe-ZnO/CdS system achieved 90.0% degradation efficiency of CIP within 120 min under visible light. Impressively, Fe-ZnO/CdS heterojunction showed practical degradation capability in complex aqueous environments and excellent reusability. This study provided an effective strategy for the design of metal oxide-based photocatalysts and offered a new idea for the removal of drug residual contaminants.

Caffeine, a central nervous system stimulant ubiquitously present in many plants such as coffee and tea, is conventionally quantified using chromatographic and electrophoretic techniques. Despite the advantages of rapid response, simple instrumentation, and low cost, photoelectrochemical (PEC) sensing remains underdeveloped for caffeine analysis. In this study, a novel PEC sensor was constructed by integrating BiVO 4 nanoparticles with Co-TCPP MOF on ITO (BiVO 4 /Co-TCPP MOF/ITO), with the aim of caffeine detection. A series of structural, morphological, optical and photoelectrochemical analyses were conducted on the BiVO 4 /Co-TCPP MOF/ITO electrode. The results demonstrated that the incorporation of Co-TCPP MOF significantly enhanced the photoelectrochemical performance of the material attributable to their extensive π-conjugated system, achieving a photocurrent density of 2.01 mA/cm 2 at 0.6 V (vs. Ag/AgCl), approximately 3.3-fold higher than pristine BiVO 4 (0.59 mA/cm 2 ). After optimization of key parameters including Co-TCPP MOF dosage, electrolyte, applied bias, the sensor exhibited a robust linear response to caffeine in the range of 0.5–120 μM, with a detection limit of 0.12 μM. Moreover, it displayed excellent selectivity, reproducibility (RSD < 3.5%), and long-term operational stability. Application to real tea and coffee samples achieved satisfactory recoveries (95.8–103.2%), with results consistent with HPLC-MS/MS, confirming its reliability. This work provides an efficient PEC caffeine sensing platform and new insights for designing MOF-semiconductor hybrids for advanced optoelectronic sensing.

The food packaging films with tunable multiple functionalities like sustained antibacterial activity, good light blocking and suitable water vapor permeability present significant practical implications for food preservation. Herein, metal-organic framework (MOF) based nanozyme with oxidase-like activity was constructed simply by chelating platinum ions, named as MOF-Pt. MOF-Pt was then incorporated into the chitosan (CS) film to form the CS-MOF-Pt composite film. Compared to the pure CS film, CS-MOF-Pt film possessed extra excellent antibacterial effect and light blocking abilities in addition to enhanced hydrophobicity with water contact angle from 52.19° to 80.38°. When the CS-MOF-Pt film was used to pack blueberries and cherries, the shelf life of these fruits was obviously prolonged by 4–6 days, with good appearance and minimum weight and polyphenol loss, demonstrating the suitability of the CS-MOF-Pt film for fruit preservation. This study provides a new way for constructing antibacterial food packaging film with multiple functionalities.

Solid polymer electrolytes (SPEs) are promising solutions to address insufficient energy density along with the safety risks brought by liquid electrolytes in commercial lithium-ion batteries. Nevertheless, SPEs are still limited by low room-temperature ionic conductivity and weak mechanical properties, which greatly restrict their practical application. In this work, a poly(ethylene oxide) (PEO)-based SPE composed of rigid substrates was proposed, which showcased a high Young’s modulus of 3.38 MPa. Meanwhile, with the inorganic MOF filler and organic succinonitrile (SN) plasticizer, the Z@MEL/PEO-SN SPE demonstrated a high ionic conductivity of 5.5 × 10–5 S·cm–1 and lithium transference number of 0.46 at 25 °C. The Li|Z@MEL/PEO-SN|Li symmetric cell could cycle stably for over 2000 h at a current density of 0.025 mA·cm–2 at ambient temperature. The Li|Z@MEL/PEO-SN|LiFePO4 full cell maintained a capacity retention of 94.2% after 100 cycles at room temperature at 0.2 C. These results suggest that this SPE is a promising candidate for the next generation of solid-state lithium-ion batteries with a high energy density and improved safety.

Recent advances in flexible metal-organic framework (MOF) films have injected momentum into the development of wearable gas sensors. However, current MOF-based wearable sensors suffer from mutual interference and often compromise in power consumption and wearing comfort, limiting their suitability for skin-interfaced applications. Here, we report a wireless, battery-free, wearable gas sensor patch based on a flexible inductance-capacitance (LC) resonator. This sensor features a bilayer flexible film composed of a 2D bimetallic Cu/Co-HHTP conjugate MOF (c-MOF) sensing layer and a Pd/SSZ-13 zeolite overlayer. Specifically, the zeolite overlayer functions as an NO2-adsorbing interface that captures incoming NO2 molecules, thereby preventing them from reacting with the underlying 2D c-MOF sensing layer. Accordingly, the wireless sensor achieves linear and interference-resistant detection of low concentrated NH3 even in the presence of NO2, while maintaining excellent mechanical flexibility, cyclic stability, and negligible baseline drift, exhibiting less than 6.2% response attenuation after repeated bending at 120°. The performance of the device is further validated through a skin-adherent, wireless, passive sensing system capable of continuous NH3 monitoring in complex environments. The proposed wireless wearable MOF-based sensor patch is highly transformative, offering benefits for various wearable applications. Device performance under high-humidity conditions is still constrained, indicating that further optimization is necessary.

Oral treatment of inflammatory bowel disease (IBD) faces significant challenges of poor targeting, low bioavailability, and systemic toxicity, necessitating intelligent stimuli-responsive delivery systems. Here, we design and synthesize a pH/hypoxia dual-responsive pendant azobenzene-functionalized MOF (Azo-MOF). The uniformly distributed azobenzene pendants serve as intrinsic gating sites, forming “snap-top” encapsulation with β-cyclodextrin through host-guest interactions that prevent premature 6-mercaptopurine leakage while enabling rapid stimuli-triggered release, creating a postmodification-free supramolecular gated delivery nanosystem (CAMM). CAMM exhibits hypoxia-triggered burst release and alkaline-sustained release, with <5.0% drug leakage during gastrointestinal transit and >90.0% cumulative release at inflammatory sites. Notably, the Azo-MOF carrier scavenges reactive oxygen species through synergy between its conjugated π -system and metal coordination environment, providing antioxidant protection alongside drug delivery. In dextran sulfate sodium-induced colitis models, CAMM outperformed free drug, achieving near-complete weight recovery, downregulating proinflammatory cytokines, restoring intestinal barrier integrity, and rebalancing gut microbiota by enriching Lactobacillus and Bifidobacterium while suppressing opportunistic pathogens. This study integrates targeted delivery, antioxidant therapy, and microbiota modulation, offering an effective strategy for precision IBD treatment.

Industrial wastewater discharge and oil spills pose significant threats to both ecological systems and human health. However, conventional hydrophobic materials with a single functional capability are often inadequate for addressing the diverse challenges associated with complex oil–water mixtures encountered in oily wastewater treatment. Herein, two-phase material with ethanol-triggered, switchable surface wettability was successfully fabricated. Cotton balls were Co-modified with a hydrothermally synthesized cobalt-based metal-organic framework and polydimethylsiloxane, a low-surface-energy polymer. The surface wettability of the modified cotton balls reversibly transitions from a hydrophobic and oleophilic state to a hydrophilic and underwater oleophobic state upon ethanol impregnation, and is fully restored to the original hydrophobic state after drying. Benefiting from this unique switching mechanism, the modified cotton balls enable the on-demand separation of diverse oil-water mixtures. Beyond two-dimensional cotton substrates, the hydrophobicity of three-dimensional cotton fabrics was significantly enhanced via surface coating with a cobalt-based metal-organic framework and hexadecyltrimethoxysilane. The resulting three-dimensional cotton fabrics exhibit a high water contact angle of 142.3 ± 2°, along with excellent self-cleaning performance and mechanical stability. This work demonstrates the effective application of cobalt-based metal–organic frameworks in regulating surface wettability across multidimensional materials.

Two-dimensional metal–organic framework (MOF) membranes have emerged as competitive candidates for efficient gas separation owing to their ultrashort diffusion pathways and highly tunable nanochannels. However, unavoidable linker rotation within 2D frameworks constrain accurate molecular sieving. Herein, heteroleptic Zn(bim)(OAc) nanosheets are employed for constructing high-performance membranes, where cooperative 2D-3D linkers coupling regulates framework motions. The 3D acetate (OAc − ) linkers limit the amplitude of motion, whereas planar 2D benzimidazolate (bim) linkers introduce locally rotational freedom through weaker M−N coordination bond, generating precise angstrom-level, dynamically tunable pore window. The heteroleptic membrane achieves considerable H 2 /CO 2 selectivity of ∼ 134, surpassing the upper bounds of traditional polymer membranes. This work demonstrates that cooperative 2D-3D linkers coupling provides a feasible pathway to engineer precise, dynamically tunable apertures in 2D MOF nanosheet membranes, offering a promising avenue for designing high-performance membranes.
