Low conductivity and slow reaction kinetics are partly responsible limiting the sensing performance of metal-organic-framework (MOF) derived metal oxides, which can be overcome by rational composition and novel microstructural design. In this study, hollow dandelion-like Ce-Zn MOF/reduced graphene oxide (rGO) nanosheets precursor were synthesized by solvothermal reaction and the precursor was annealed to obtain CeO 2 -ZnO/rGO (CZO/rGO). The effects of polyvinylpyrrolidone (PVP), rGO and annealing temperature on its morphology and sensing properties were investigated. The unique morphology of CeO 2 -ZnO provides abundant active sites and large specific surface areas which can improve the ion diffusion efficiency, and the high conductivity of rGO reduces the interfacial resistance and improves the electron transfer rate. The optimized CZO/rGO/ITO electrode achieves a high sensitivity of 17.67 μA·μM -1 ·cm -2 and a limit of detection of 2.1 nM (S/ N = 3) for dopamine (DA) detection. This study broadens the application of MOF derivatives in DA sensing.

The large-scale production and disposal of polyethylene terephthalate (PET) and antibiotics pose significant environmental challenges. Thus, the high-value utilization of PET to degrade antibiotics is of great significance. Zn-MOF-X catalysts were fabricated via a two-step hydrothermal approach, with waste PET plastic flakes and zinc metal salt serving as the initial materials. Notably, Zn-MOF-2.5 exhibited remarkable effectiveness for peroxymonosulfate (PMS) activation to degrade oxytetracycline (OTC), reaching a removal rate of 93.01 % within 90 min under visible light. This catalyst demonstrated stable pH adaptability, strong resistance to interference and excellent stability across diverse and complex aqueous environments, retaining a 70 % OTC removal efficiency after eight cycles. To investigate the OTC degradation process via HPLC-MS and toxicological studies, the toxicity profiles of resulting intermediates were evaluated. This study investigated the properties of OTC using density functional theory calculations, assessed the application potential of the Zn-MOF-2.5/PMS system with economic analysis, and ultimately proposed a novel method for preparing efficient environmental pollutant removal catalysts from waste PET.

An intelligent and active hydrogel was developed by incorporating alizarin and a zinc-gallic acid metal-organic framework (Zn-MOF) into a polyvinyl alcohol matrix for simultaneous shrimp freshness monitoring and preservation. Zn-MOF imparted enhanced mechanical strength (1.3-fold tensile and 2.9-fold compressive modulus increases), greater amine gas adsorption (evidenced by an 11 rise in euclidean distance, ED), and strong antimicrobial and antioxidant activities, including 100 % antibacterial efficacy and radical scavenging rates of 81.09 %, 94.56 %, and 70.54 % for DPPH, ABTS, and OH radicals. The hydrogel showed a distinct yellow-to-purple transition across pH 6–12, serving as a visual indicator of shrimp spoilage, with ED values nonlinearly correlated with total volatile basic nitrogen (TVB-N) levels (R 2 = 0.9847). A smartphone-based portable device enabled rapid freshness evaluation via color changes. The hydrogel also reduced total viable count (TVC), TVB-N, and pH levels, extending shrimp shelf life by at least 3 days, demonstrating its industrial potential.

A promising double-ligand strategy for the delivery of active corrosion inhibitors by a Zn(II)-based metal–organic framework (Zn-MOF) is developed. Zn-MOF compounds were synthesized by a facile one-pot solvothermal method and characterized. The Zn-MOF is based on the corrosion inhibitor benzotriazole (BTA) and 2,5-furandicarboxylic acid (H2FDA) ligand, which is a promising renewable building block alternative to terephthalic or isophthalic acid. The crystal structure and morphology are characterized by single-crystal X-ray diffraction analysis, powder X-ray diffraction analysis (PXRD), Fourier transform infrared spectroscopy (FT-IR), and scanning electron microscopy (SEM). The synthesized MOF crystallites are in the trigonal space group R3c with the cell parameters in a three-dimensional (3D) anionic framework. Their ability to inhibit the corrosion process of aluminum alloy 2A12 in NaCl solution was also evaluated by immersion tests in solutions with and without a MOF. The postcorrosion analysis was performed by SEM and X-ray photoelectron spectroscopy (XPS). Additional information about the inhibition efficiency was obtained by electrochemical impedance spectroscopy (EIS). The results suggest that the as-synthesized MOF can release the inhibitors and form protective layers effectively on the surface of the aluminum alloy. The use of inhibitor-loaded MOF nanocontainers provides promising opportunities for the smart delivery of inhibitors and effective corrosion protection of 2A12 aluminum alloys.

The exposed active sites of ZIF-8 is considered as the key to boost the kinetics of photoelectrochemical (PEC) water splitting. However, the terrible stability under irradiation and aqueous conditions significantly limit the practical application for fabricating the efficient photoeletrode. Herein, a novel strategy is employed for solving the stability of Zn-MOF (ZIF-8) by partially replacing Zn 2+ ions by Ni 2+ ions. The TiO 2 photoelectrode is selected as a testing model to study the superiority of TiO 2 –ZnNi MOF for PEC water splitting. TiO 2 –ZnNi MOF exhibits a strong photocurrent density of 1.00 mA/cm 2 (1.23 V vs. RHE), which is 2.7 and 1.7 times that of TiO 2 and TiO 2 –Zn MOF, respectively. More importantly, the photocurrent density of TiO 2 –ZnNi MOF maintains almost 100% for 2 h, while TiO 2 –Zn MOF significantly decays to 81.6% for just 8.3 min, indicating the successful achievement for promoting the stability of Zn-MOF. Therefore, this work proposes a reasonable route to simultaneously enhance the PEC efficiency and stability of TiO 2 –Zn MOF for the first time, which provides a new guidance for the design of highly stable photoelectrode.

Antibiotic-resistant genes (ARGs) and antibiotics were detected in various environmental media. Metal-organic framework materials (MOFs) have great advantages in removing many pollutants in water. However, their microporous structure and poor hydrothermally stability make them difficult to realize efficient adsorption performance of macromolecular pollutants. Therefore, this study is devoted to preparing MOF-derived mesoporous carbon materials with excellent pore structure and stability so as to improve the adsorption performance of macromolecular antibiotics in water. In this study, the surface morphological structure of the MOF material was regulated from the preparation process. Firstly, the template agent formed micelles in the MOF framework, so that self-assembly and crystal growth were carried out under the guidance of cooperative templates. Secondly, the morphological structure of the material surface was modified by high-temperature calcination and surface etching. A series of graphitic carbon material MC-X with tunable mesoporous structure were prepared using Zn-MOF materials as precursors and N-Cetyldimethylamine as template. The pore size and mesoporous ratio of the MC-0.3 material had undergone large changes, the pore size varied from 1.73 nm to 3.94 nm, and the mesoporous ratio transformed from 12.6% to 97.71%. Unexpectedly, the material converted from hydrophilic to hydrophobic, and possessed an ultra-high ceftazidime (CAZ) adsorption capacity of 371.18 mg·g −1 . The adsorption mechanisms of CAZ on MC-0.3 were mainly molecular size matching selection, hydrophobic effect and hydrogen bonding . After 5 adsorption-desorption cycles, MC-0.3 could maintain about 90% of the initial adsorption capacity.

Salmonella is one of the most prevalent pathogens causing foodborne diseases. In this study, a novel electrochemical immunosensor was designed for the rapid and accurate detection of Salmonella typhimurium ( S. typhimurium ) in milk. Platinum nanoparticles and Co/Zn-metal–organic framework @carboxylic multiwalled carbon nanotubes in the immunosensor acted synergistically to enhance the sensing sensitivity and stability. The materials and sensors were characterised using X-ray diffractometry, scanning electron microscopy, Fourier-transform infrared spectroscopy, differential pulse voltammetry, cyclic voltammetry, and other techniques. The optimised immunosensor showed a linear response for S. typhimurium concentrations in the range from 1.3 × 10 2 to 1.3 × 10 8 CFU mL −1 , with a detection limit of 9.4 × 10 1 CFU mL −1 . The assay also demonstrates good specificity, reproducibility, stability, and practical application potential, and the method can be extended to other foodborne pathogens.

Herein, two-dimensional Zn(Bim)(OAc) nanosheets (ZNS) were prepared using ultrasonication and surfactant-assisted methods. Subsequently, it was used as nanocontainer loaded with benzotriazole (BTA) corrosion inhibitor to fabricate BTA@ZNS nanocomposites with pH-controlled release characteristics. The morphology analysis exhibits that BTA@ZNS has a distinct lamellar structure. UV spectrophotometer measurements indicated the release rate of BTA reached 94.38 % in 24 h at pH=1. Adding BTA@ZNS as fillers into epoxy resin (EP) coating can form BTA@ZNS/EP composite coating with active anti-corrosion properties. Electrochemical impedance spectroscopy (EIS) demonstrates that BTA@ZNS/EP coating has superior corrosion resistance than other EP-based coatings. The enhanced anti-corrosion performance is ascribed to the barrier effect and acid-responsive controlled release of BTA@ZNS.

Electrospun micro-/nanofibers with tailor-made specific binding sites are extremely popular due to their tremendous potential in separation applications. In this work, teamed boronate affinity (TBA)-functionalized molecularly imprinted hollow carbon electrospun nanofibers (MI-HCESNFs) derived from ZIF-8/PAN fibers with selective binding sites toward shikimic acid (SA) are presented. Each ingredient used in this strategy plays its own part: HCESNFs with excellent structural characteristics as the highly porous electrospun substrate, KH560 as the grafting material for the follow-up polyethyleneimine (PEI) modification, PEI as the dendritic platform to approach more boronic acid owing to its long chain with abundant amino groups, and TBA molecular group as the functional monomer to specifically bind with SA under the neutral condition. Benefiting from the porous structure, the high density of boronic acid, and the highly accessible imprinted sites on the surface, MI-HCESNFs show strong affinity and selectivity to the SA molecules. The adsorption capacity of MI-HCESNFs can reach 127.8 mg g–1, which is 3.1 times larger than that of the non-imprinted material. Besides, MI-HCESNFs are stable when treated with continuous ultrasonication and can be recycled eight times with a slight loss of 8.615% on the adsorption quantity. This work presents a new strategy to prepare boronate affinity adsorbents based on the electrospinning technique for the capture of SA and also proposes a path for the integration of molecularly imprinted polymers and electrospinning.

Radioactive strontium ( 90 Sr) contamination in water bodies poses one of the most persistent and serious threats to both ecological safety and public health, owing to its long half-life, high environmental mobility, and strong propensity for biological accumulation. However, a rapid and sustainable synthetic route for bimetallic MOF-74 with high Sr 2+ adsorption capacity remains lacking. This study reports a solvent‑free mechanochemical strategy for the synthesis of a bimetallic Cu/Zn-MOF-74 (CZ-M74-11) using a spiral gas-solid flow (S-GSF) method in just 1 min. The material achieves 98.26% Sr 2+ removal within 15 min and exhibits a maximum Langmuir adsorption capacity of 295.13 mg·g −1 at 303.15 K. Kinetic and thermodynamic analyses indicate that the adsorption is spontaneous and exothermic. XPS and FT-IR analyses, together with cyclic desorption data, reveal that Sr 2+ uptake proceeds primarily through outer-sphere complexation, with a minor contribution from inner‑sphere coordination involving carboxylate groups. This work addresses the gap in rapid and sustainable routes for bimetallic MOF-74 synthesis by introducing an S-GSF method that achieves excellent adsorption capacity and ultrafast kinetics for Sr 2+ removal.

Herein, a novel bioinspired radial porous zinc-based metal-organic framework (Zn-MOF) doped sodium alginate/chitosan derivatives/pullulan-based SA/PSCS/Pul/Zn-MOF (SPCP/Zn) composites sponge with excellent antioxidant and antibacterial properties was fabricated by the ice-templating method. Boric acid (BA) and Ca 2+ , which were respectively used as hydrogen- and ionic- bonding cross-linkers, provided strong mechanical properties for sponge matrix composed of SA, PSCS, and Pul. The obtained SPCP/Zn sponge exhibited uniform porous morphology, proper hydrophilicity , and admirable biocompatibility. In addition, the SPCP/Zn sponge achieved a sustained release of Zn 2+ and gallic acid , which displayed powerful antibacterial and antioxidant activities . Importantly, the SPCP/Zn sponge exhibited shorter rapid hemostasis (20.4 ± 2.9 s) and lower blood loss (19.8 ± 4.3 mg). The SPCP/Zn sponge also showed faster wound closure ratio for the rat full-thickness skin defect model. It was revealed that SPCP/Zn sponge could significantly accelerate and enhance wound healing through downregulating inflammatory cytokines (TNF-α, IL-6) and increasing the expression of growth factors (VEGF). Due to its excellent properties, the SPCP/Zn sponge may have promising potential in wound healing applications.

With the increasing environmental degradation, bacterial contamination is threatening human health. Thus, it is crucial to develop an efficient and safe antimicrobial strategy. In this work, the polyacrylonitrile (PAN) nanofiber membranes contained Co/Zn-metal organic framework (Co/Zn-MOF@PAN) were fabricated via electrospinning technique and surface modified method. The optimal preparation condition for nanofiber membranes were further regulated by adjusting 2-methylimidazole (2-MIM) concentration and secondary growth time. The antibacterial activity of Co/Zn-MOF@PAN against Escherichia coli ( E. coli ) and Staphylococcus aureus ( S. aureus ) were determined by turbidimetry and plate colony-counting methods. As the 2-MIM concentration and secondary growth time increased, the hydrophilicity and surface roughness of Co/Zn-MOF@PAN nanofiber membranes increased. In addition, when the 2-MIM concentration was 0.16 mol/L, the Co/Zn-MOF@PAN nanofiber membranes had an antibacterial rate of over 99% against E. coli and S. aureus ., and the minimum inhibitory concentration (MIC) value of Co/Zn-MOF@PAN nanofiber membranes was 0.75 mg/mL. It could be indicated that Co/Zn-MOF@PAN nanofiber membranes exhibited an excellent antibacterial effect. The main antibacterial mechanism of nanofiber membranes was that ROS produced by MOFs could destroy the physiological activities of the bacteria lead to death. The Co/Zn-MOF@PAN nanofiber membranes will have a wide range of applications value in the fields of antibacterial packaging materials and sterilization of water resources.
