Metal-Organic Frameworks (MOFs) have been widely used for the antibiotic pollution control. However, it remains a challenge to simple design and synthesis of multifunctional MOFs for sensing and degradation antibiotics. Herein, a multifunctional UiO-66(Zr/Ce)-NH 2 ratiometric fluorescence sensing and photocatalytic degradation platform was rapidly and simply constructed at room temperature by a one-pot method using a dielectric barrier discharge device. The mixed-metal centers and mixed-ligands of this platform enabled effective ratiometric fluorescence sensing of tetracycline (TC), along with a visual fluorescence shift from blue to yellow-green color. The platform demonstrated a detection of TC ranged from 200 nM to 15 μM, with a detection limit of 43 nM. Moreover, the UiO-66(Zr/Ce)-NH 2 exhibited strong light absorption and efficient photogenerated carrier separation, thus offering excellent degradation performance of TC compared with that of MOFs with single metal center, mixed ligands or mixed metal centers. The mechanism of fluorescence detection and potential charge transfer pathways by the UiO-66(Zr/Ce)-NH 2 were analyzed. This work provided a new approach for the simple design and synthesis of multifunctional MOFs platforms.

In this study, UiO-66(Zr) and its derivative (UiO-66-C) are employed as supports to prepare shape stabilized PCM (U/SA-X and UC /SA-X) for resolving the melting leakage and poor thermal conductivity of stearic acid (SA). Thermal storage performance, including phase change enthalpy, supercooling degree, phase change temperature, thermal conductivity, and shape stability of U/SA-X and UC/SA-X, are compared. Preliminary characterization reveals that the physicochemical property evolution of the support impacts the thermal storage performance of SA . UiO-66 with microporous structure is unfavorable to enhance the shape stability of SA. U/SA-X exhibits low thermal storage efficiency and high supercooling degree owing to nanoconfinement and hydrogen bonding. By contrast, UiO-66-C possesses mesopores and graphitic structure that allows for a remarkable thermal storage performance of UC/SA-X. In detail, UC/SA-50 exhibits an ideal thermal storage performance, where the thermal conductivity (0.531 W/(m·K)) increases by 141 % in comparison to SA with a high phase change enthalpy of 93.6 J/g and low supercooling degree of 0.24 °C. It also shows satisfying thermal reliability that the thermal property of UC/SA-50 maintains stability even after 100 thermal cycles. In addition, the photothermal conversion efficiency of UC/SA-50 is up to 83.06 %.

The efficient degradation of emerging pollutants in water, represented by CBZ, is receiving increasing attention from all sectors of society. Although advanced oxidation reactions represented by Fenton reaction can efficiently degrade emerging pollutants, the problem of iron sludge that comes with it is hindering the further promotion of this technology. Herein, UiO-66(Zr)-2OH material was synthesized by hydrothermal method and loaded with Pd 0 NPs on the surface of the material by in situ reduction. The MOFs-H 2 -Accelerated Catalytic Fenton system was constructed by accelerating the regeneration of Fe(II) in the system by activating the [H] produced by H 2 introduced into the system at room temperature and pressure. Within 180 min, the removal of the target pollutant CZB could reach more than 99 % under the condition of only 25 µmol of Fe(II) and 25 mmol of H 2 O 2 .

Background Phosphorus in wastewater is a major environmental concern. Very small phosphorus inputs in the environment can cause algal blooms that can deplete the dissolved oxygen and decrease the water quality, leading to eutrophication. Furthermore, some algal blooms produce toxins and bacterial growth that can cause human illness through exposure to contaminated water. Therefore, It is necessary to remove phosphorus before it is discharged to the environment. Methods adsorbent enhanced adsorptive ultrafiltration (UF) has recently emerged as an advanced ion recovery technology with membrane filtration function and adsorption function, and is very effective in removing cationic bisphosphate and anionic phosphate. Significant findings Herein, a novel defect-rich and covalently-crosslinked octanoic acid (OA)-UiO-66(Zr)-NH 2 /PVC adsorption ultrafiltration membrane are designed for removal of phosphate ions in water. The OA-UiO-66-NH 2 /PVC-33 membrane achieved the adsorption capacity (∼30 mgg −1 ) and higher removal efficiency (∼90%). The OA-UiO-66(Zr)-NH 2 /PVC ultrafiltration membrane exhibited a higher water flux of 266.9 L/(m 2 ·h·bar) compared to those of pristine PVC and UiO-66-NH 2 /PVC. Filtration and cyclic stability experiments reveal that OA-UiO-66(Zr)-NH 2 /PVC membrane can maintain a high retention capacity and exhibit excellent regeneration performance after 5 cycles.

The non-destructive, real-time, and visual assessment of fish freshness is crucial for maintaining food quality and safeguarding public health. In this study, a pH-sensitive and colorimetric enhancement film was developed using a carboxymethyl cellulose/anthocyanin/metal-organic framework (CMC-BA-UIO). The concentration of UIO-66 in the film-forming solution significantly influences the mechanical properties and ammonia responsiveness of the indicator film, with the CMC-BA/2.5%UIO-66 variant exhibiting optimal performance. When utilized for real-time fish freshness monitoring at 4 °C, the CMC-BA/2.5%UIO-66 indicator film demonstrated a distinct color transition from purple to yellow, which exhibited a strong correlation with the rot index (TVB-N) of the fish. These findings indicate that the developed indicator film has potential applications in intelligent packaging for monitoring food shelf life, providing a visual alert to producers and consumers regarding food spoilage.

Abstract Catechol-functionalized UiO-66(Zr) holds considerable promise for targeted catalytic transformations owing to its distinctive electronic and structural properties. However, the direct synthesis of such frameworks has remained a persistent synthetic challenge. Herein, we report a rational, solvent-free, one-pot synthetic strategy enabling precise control over catechol functionalization in UiO-66(Zr) (UiO-66(Zr)-(OH)2) with well-defined hierarchical porosity. The optimized UiO-66(Zr)-0.25(OH)2 displays markedly improved catalytic performance in the esterification of levulinic acid (LA) with primary alcohols to yield alkyl levulinates. This superior activity arises synergistically from three key features: (i) increased Brønsted acidity imparted by the ortho-dihydroxyphenyl groups; (ii) a hierarchical pore architecture that enhances mass transport and substrate accessibility; and (iii) strong adsorptive affinity for both LA and alcohol substrates. Under standardized 12 h batch reactions with an alcohol-to-LA molar ratio of 20 and 50 mg of catalyst, UiO-66(Zr)-0.25(OH)2 achieves LA conversions of 98.9, 97.9, 95.6, and 94.3% with methanol, ethanol, 1-propanol, and 1-butanol, respectively, while maintaining >99.9% selectivity for the corresponding products of alkyl levulinates at optimally tuned reaction temperatures (60, 70, 80, and 100 °C). This work establishes a practical and environmentally sustainable synthetic strategy for the rational design of functionalized metal–organic frameworks, enabling high-efficiency, heterogeneous catalysis in targeted reactions.

The removal of indoor/outdoor toluene by photocatalysis has drawn much attention due to its low energy consumption and easy availability. However, light inevitably generates heat, and pollutants desorb from catalysts as the temperature rises, which is not beneficial to degradation. Contrast to the frequently occurred phenomena, we firstly found that the adsorption capacity of UiO-66 (Zr) on toluene increased with increasing temperature as adsorption isotherms and in-situ Fourier transform infrared spectra (in-situ FTIR) showed. The optimum temperature was 30 °C. This stage in which adsorption capacity was positively correlated with temperature was called heating-induced adsorption, which achieved a toluene removal efficiency of 69.6 %. By density functional theory (DFT) calculations and changing the metal centers and organic ligands of UiO-66 (Zr) respectively, we disclosed that the heating-induced adsorption was mainly related to the π-π stacking interaction of MOF ligands and toluene. The analysis of samples before and after adsorption showed that the interaction between UiO-66 (Zr) and adsorbed toluene facilitated the charge transfer and prolonged the carrier lifetime, leading to the increase of hydroxyl radicals (•OH) in photocatalysis. Therefore, a synergistic effect between heating-induced adsorption and photocatalysis was proposed by analyzing the adsorption of toluene on UiO-66 (Zr) in detail. This work provided new viewpoint to understand the role of concomitant heat contributed to the adsorption and degradation of toluene during photocatalysis.

The abuse and persistent use of Lomefloxacin (LOM) produces residues that deteriorate the ecological environment and endanger human health. Therefore, it is highly urgent to establish a simple and reliable method for the determination of LOM to guarantee food safety. Herein, a sensitive voltametric sensor based on bimetallic UiO-66(Zr/Ce) MOF/reduced graphene oxide (UiO-66 (Zr/Ce)/rGO) was fabricated for the determination of trace LOM residues in milk. The UiO-66(Zr/Ce)/rGO increased the electroactive surface area and lowered the charge transfer resistance. Due to the synergistic interactions between UiO-66(Zr/Ce) MOFs with good electrocatalytic activity and rGO nanosheets with high electrical conductivity, the UiO-66(Zr/Ce)/rGO/GCE exhibited the highest peak current response of LOM, 4.2-fold higher than the bare GCE. Consequently, the UiO-66(Zr/Ce)/rGO showed remarkably electrocatalytic activity for LOM oxidation with two broad linear detection ranges (0.03 – 2.0 μM and 2.0 – 30 μM), high sensitivities (5.1254 and 0.2198 μM μA −1 ), and a low detection limit (5.0 nM). The UiO-66(Zr/Ce)/rGO exhibited strong anti-interfering ability against potential interfering species even at high concentration, and maintained robust voltametric responses up to 25 days. Moreover, the UiO-66(Zr/Ce)/rGO/GCE achieved accurate determination of trace LOM residues in liquid milk with good recovery (96.11 − 103.2 %) and highly consistent sensitivity with that in PBS.

The great challenge in capturing harmful volatile organic compounds (VOCs) using Metal-Organic-Frameworks (MOFs) materials still rely on rationally modifying its appreciable microporous character in hydrostable structure. Defected structure in MOFs might be very beneficial for creating expected engineering adsorbent. In this study, defect-engineering UiO-66 via imparting acetic acid (HAc) as an interfering agent was successfully fabricated by a simple hydrothermal method. The physicochemical properties of the obtained materials were intensively ascertained and identified through a series of applicable characterizations. By the proper participation of tuning concentration of HAc (HAc/TAc = 24, molar ratio), the obtained adsorbent UiO-66–1.0HAc was endowed with the highest adsorption capacity for benzene (367.13 mg g −1 , 25 °C) in the known UiO-66 materials, which was 41.9% higher than that of the non-defected UiO-66. With a higher optimized added amount of HAc (HAc/TAc = 48, molar ratio), the adsorption capacity of UiO-66–2.0HAc to toluene achieved the highest capture values (410.21 mg g −1 , 25 °C), which boosted 93% compared with the original counterpart. This demonstrated improvement was ascribable to the imparted structural defect-engineering derived from the missing-linkers of MOFs increasing the unsaturated adsorption site and concomitant enlarged structural properties of the resultant material. By identifying the DIH (Difference in adsorption heat), the obtained maximum adsorption selectivity of UiO-66–1.0HAc to toluene/water was further enhanced to 64.4, which was 3.7 times the original UiO-66, owing to the existed defect-engineering in adsorbents, indicating the potential differential competitive adsorption effect for benzene and toluene under humid conditions.

The escalating economic and ethical concerns associated with camel meat adulteration using cheaper horsemeat necessitate the development of rapid, on-site detection technologies that overcome the limitations of conventional laboratory-based methods. In this study, a portable electrochemical DNA biosensor was fabricated by integrating a polydopamine (PDA)-modified screen-printed carbon electrode (SPCE) with a nucleic acid-functionalized UIO-66(Zr) metal-organic framework (MOF). The PDA coating facilitated stable, covalent immobilization of DNA capture probes through Schiff base reactions, while the UIO-66(Zr) MOF functioned as a high-capacity signal amplifier owing to its large surface area and intrinsic redox activity. This synergistic architecture enabled ultrasensitive detection, achieving a limit of 3.57 pmol/L for horsemeat DNA and 0.5 g/kg adulteration in camel meat blends—significantly surpassing the performance of existing detection methods. The biosensor exhibited excellent specificity by distinguishing single-base mismatches, along with high reproducibility (RSD = 4.12%), operational stability over 15 days, and accurate recovery rates ranging from 91.7% to 112.4% in spiked samples. Its disposable electrode format, cost-effectiveness, and compatibility with portable potentiostats underscore its strong potential for on-site meat authentication. Overall, this work provides a practical and scalable solution to combat meat fraud in resource-limited settings and establishes a versatile MOF-electrode nanoassembly platform for advanced food safety monitoring.

The accumulation of antibiotics in aquatic ecosystems poses a serious threat to the environment and to human health. Tetracyclines (TC) account for a significant proportion of antibiotic residues worldwide. In order to overcome the limitations of conventional degradation methods, we created a three-component S-scheme heterojunction consisting of BiVO 4 /MWCNTs@NH 2 -UiO-66 (Zr) using a two-step solvothermal process. This synergistic integration utilises: (i) MWCNTs as electron transport bridges; (ii) NH 2 -UiO-66 (Zr) for high TC adsorption (surface area of 931.86 m 2 g −1 ); and (iii) BiVO 4 for visible light harvesting. This architecture broadens light absorption, reduces charge recombination and enables dual-pathway Reactive Oxygen Species (ROS) generation. Under visible light, the optimised catalyst achieves 95.2 % TC degradation within 90 min–7.73 times faster than pristine BiVO 4 (k = 0.02721 vs. 0.00352 L mg −1 ·min −1 ). Radical trapping and EPR analyses confirm ·O 2 − and h + as the dominant species, while LC-MS reveals three degradation pathways. With 85.3 % activity retention after five cycles, this work provides a blueprint for the design of efficient, antibiotic-mineralising photocatalysts.

In this study, a series of metal–organic frameworks (MOFs) NH 2 -UiO-66- x HAc catalysts were synthesized by solvothermal method using acetic acid (HAc) as a modulator, and were applied to the cycloaddition of CO 2 and epichlorohydrin (EPIC) under ambient pressure. Influences of the modulation by HAc on morphologies and structures of the MOFs are demonstrated via PXRD, FESEM, FTIR, N 2 adsorption–desorption, XPS and 1 H NMR characterizations. The results show that the MOFs containing mesoporous pores can be prepared by adjusting the concentration of HAc. By optimizing the amount of HAc added, the specific surface area of NH 2 -UiO-66-8HAc is as high as 879.17 m 2 ·g −1 , which is 28.3% higher than that of the original MOFs. And the evaluation of catalytic performance showed that HAc modulation enhanced the activity of NH 2 -UiO-66- x HAc under mild conditions. The exposure of Lewis acid sites, increased specific surface area and porosity via the modulation of HAc defective ligand can be supposed the key factors to determine the enhanced catalytic activities. In addition, considering the influence of gas concentration on the reaction, the concept of TOP (Turnover of Pressure, defined as the mass of conversions of a unit mass catalyst under unit pressure and unit time) was first proposed in this article.
