The involvement of peroxymonosulfate (PMS) in advanced oxidation processes represents a promising technology that can effectively reduce recalcitrant pollutants. In this study, taking advantage of the abundant and flexibly tunable terminal μ3-O groups of UiO-66, the high-efficient Mn modified UiO-66(Mn@UiO-66) was were prepared by direct complexation between μ3-O groups and Mn ions. It was optimized that the Mn@UiO-66 exhibited excellent catalytic performance to activate PMS for bisphenol A (BPA) degradation. Quenching experiment and electron paramagnetic resonance (EPR) showed that the non-free radical pathway was dominant in BPA degradation, and singlet oxygen (1O2) was the main active species. In addition, an abnormal pollutant dependent PMS activation behavior was revealed; UiO-66 enriched with μ3-O promotes PMS activation via the μ3-O-mediated Zr-O-Mn electron transfer pathway, boosting performance for selective degradation of target pollutants from water. Interestingly, the presence of multiple coexisting cations and anions have little effect on the BPA degradation rate and PMS decomposition. The Mn@UiO-66/PMS system could also degrade effectively various organic pollutants, indicating its potential practical application value.

Heavy metal contaminated soil remediation methods are mostly chemical washing, fixed stabilization, and bioremediation techniques. However, chemical drenching can cause secondary pollution; fixation stabilization remediation is incomplete and may fail; and bioremediation has a long time period. Therefore, in this study, we synthesized a stable millimeter-scale gel spherical adsorbent, UIO-66-NH 2 @SA, to remove the pollutants from the soil contaminated with high concentrations of heavy metals by a combination of aqueous leaching and adsorption without the addition of additional chemical leaching agents. The UIO-66-NH 2 @SA can be recovered by sieving, and it still has the capacity of removing the heavy metals after four adsorption–desorption cycles. The analysis of soil properties before and after adsorption proved that the remediation process would not affect the physicochemical properties and fertility of the soil, and the characterization of x-ray diffraction, Fourier transform infrared, and XPS proved that the adsorption mechanism was mainly ion exchange and functional group complexation.

Biodiesel is being deemed a kind of important renewable energy source and also shows the great potential to replace fossil fuels to respond to global primary energy demands. However, by-product water generated during the esterification reaction of biodiesel production is not conducive to the forward progress of the reaction, and even affects the pristine structure and activity of the employed catalytic material. In this work, the hydrophobic polymeric bio-based solid acid catalyst FDCA/SA-UiO-66(Zr) was prepared by a facile grinding method using biomass-derived stearic acid (SA) and 2,5-furandicarboxylicacid (FDCA) as hydrophobic ligand and green organic linker, respectively. Accordingly, the corresponding characterization results showed that the relevant material had a good particle shape along with a highly hydrophobic network (136.4°), wherein the significant hydrophobic environment was determined to promote the adsorption of lipophilic acid and the desorption of water on the Lewis acid site. Compared with traditional heterogeneous and homogeneous acid catalysts, just at a low temperature (60.2 °C, 98.4% yield), FDCA/SA-UiO-66(Zr) exhibited superior or equivalent catalytic performance in the esterification of FFAs for biodiesel manufacture. More importantly, thanks to the stable skeleton structure of UiO-66(Zr), the catalyst demonstrated a stable structure and good reusability during 6 consecutive recycles (92.5% biodiesel yield).

A universal strategy is developed to construct a superhydrophobic and superoleophilic metal-organic framework (MOF) by an amidation reaction between amino group and acid chloride of octadecanoyl chloride. The introduction of long alkyl chain reduced the surface free energy, yielding a superhydrophobic Zr-MOF (UiO-66-NH-C18) with a high water contact angle (WCA) of 151.7°. The adsorbed amount of water on the UiO-66-NH-C18 was only 5.59 mmol/g, which was just 28 % of that on the UiO-66-NH 2 . More importantly, the hydrophobic modification improved the stability of Zr-MOFs under strong alkaline conditions (e.g., pH = 13). Furthermore, the UiO-66-NH-C18 can selectively absorb organic solvent from water and achieve continuous oil-water separation. The oil-water separation efficiency could reach up to 99.9 %. In addition, the UiO-66-NH-C18@sponge was also prepared through dip-coating of UiO-66-NH-C18 on the melamine sponge in the presence of PDMS solution. The resulting composite shows high adsorption capacities for various oils and organic solvents ranging from 32.3–66.1 g/g. The superhydrophobic UiO-66-NH-C18@sponge has potential as a promising absorbent for treatment of oily wastewater.

The treatment of oil spill and the separation of oil-water mixture have been widely concerned in recent years. In this work, a one-pot synthesis strategy is developed to prepare fluorine functionalized zirconium-based metal organic framework (Zr-MOFs) (denoted as UiO-66-1F) by using 4-fluorobenzoic acid as modulator and modifier and p-phthalic acid (PTA) as ligand. 4-fluorobenzoic acid can participate in the formation of frameworks structure and cause structural defects, causing larger surface area and hierarchically porous structure. The hydrophobicity of UiO-66-1F increases with increasing of the ratio of 4-fluorobenzoic acid to zirconium chloride and when the ratio is 10, the synthesized UiO-66-1F(10) shows high hydrophobicity with a water contact angle (WCA) of 122° while the WCA of original UiO-66 is only 21°. UiO-66-1F(10) also has good chemical stability over a wide pH range (pH 1∼11) and good hydrothermal stability. In addition, a superhydrophobic sponge (UiO-66-1F(10)@PDA@sponge) with a WCA of 150° was prepared via in situ growth of UiO-66-1F(10) on a polydopamine modified sponge (PDA@sponge). The resulting composite shows high absorption capacities for various oils and organic solvents ranging from 50.5 g/g (n-hexane)– 107.8 g/g (dichloromethane) and good recyclability.

The nanocomposite materials are highly promising candidates for adsorption applications in dyed wastewater due to their distinctive structural properties. In this work, the nanocomposite hybrids of UiO-66@GO were first synthesized by specifically anchoring Zr-based metal organic framework (MOF) of UiO-66 onto graphene oxide (GO) nanolayer through solvothermal method. Then the composite matrix microspheres (CMMs) of UiO-66@GO were subsequently prepared by embedding the obtained UiO-66@GO nanocomposite into sodium alginate (SA) microspheres through self-assembly cross-linking process. Finally, the prepared UiO-66@GO CMMs were applied for the adsorption of organic dye pollutant and showed efficient water purification performance. As a result, the UiO-66@GO CMMs exhibited selective cationic dye adsorption for Rhodamine B (RhB + ). The experimental results revealed that the adsorption kinetics followed by the pseudo-second-order (PSD) model with rate constant k 2 = 0.95 × 10 –3 g mg −1 min −1 , and the thermodynamics followed by the Langmuir model with adsorption capacity of 345.66 mg mg −1 . Notably, the UiO-66@GO CMMs demonstrated excellent adsorption removal of a significant removal efficiency of 98% towards 10 ppm Rh-B and a rapid adsorption response time of ~ 5 min. Meanwhile, the UiO-66@GO CMMs maintained long-term stability with adsorption efficiency > 95% over 30 days and effective reuse with resorption efficiency > 90% using DMF-H₂O as eluent. In this study, SA has served as a porous supporting matrix to immobilize UIO-66@GO nanoparticles, having mitigated issues of aggregation and leaching common to nanoscale adsorbents while improving reusability. The synergistic effect between UIO-66 and GO has further enhanced pollutant adsorption capacity, demonstrating significant potential for dye wastewater treatment applications.

Vapor-phase deposition for the preparation of metal–organic framework (MOF) membranes is of great interest in its scalable and sustainable manufacturing. Nevertheless, there remains no report on vapor-assisted conversion (VAC) for preparation of zirconium-based MOF membranes to date. Here, we established a VAC protocol for preparing UiO-66 membranes on the porous α-Al 2 O 3 tube. It was found that the substrate surface modification, metal-to-ligand ratio and concentration of the modulator are crucial parameters to control the quality of the resulting membrane microstructure. The obtained UiO-66 membrane exhibited excellent dye rejection rates (>99.5 %) and reliable operation stability (no reduction in separation performance during 96 h). In addition, the VAC approach also can be adopted to synthesis of high-performance UiO-66-NH 2 and MOF-801 membranes. Therefore, the VAC protocol might open new horizons in sustainable production of water-stable MOF membranes for practical applications.

We developed a new core-shell ratiometric fluorescent nanoprobe simply prepared by a seeded growth method. The strong luminescence arising from the shell formed by coordination self-assembly of an alkaline phosphatase (ALP) substrate, l -ascorbic acid 2-phosphate (AAP), and Tb 3+ , together with the weak fluorescence of the core-a metal-organic framework, UiO-66-NH 2 , constitutes an ideal dual-emission characteristic. Since AAP can be specifically cleaved by ALP, the well-formulated core-shell nanostructure was destroyed upon exposure to ALP. In this case, the luminescence of Tb 3+ was quenched due to the inefficient antenna effect, while the fluorescence of UiO-66-NH 2 was strengthened by the synergistical enhancement of dual hydrolysates to inhibit the ligand-to-metal charge transfer (LMCT) process. Using the dual signal response, this nanoprobe was employed for ratiometric fluorescence detection of ALP activity in the range of 0.05–0.6 U mL −1 with a detection limit of 0.018 U mL −1 , accompanied by a discernible fluorescence color evolution from turquoise to blue. In virtue of good properties in accuracy, sensitivity, selectivity and simplicity, this assay enabled quantitative detection of ALP activity in human serum and efficient screening of ALP inhibitors. More Importantly, a smartphone-assisted paper-based sensing platform was designed for on-site visual analysis of ALP activity in human serum, which may be very promising as a facile, portable, and robust format to facilitate relevant biological and clinical applications.

Sulfur dioxide (SO 2 ) emissions present significant environmental and health risks, yet efficiently capturing SO 2 remains challenging due to its corrosive nature and the limited performance of conventional adsorbents. In this study, we developed multivariate metal-organic frameworks (MTV-MOFs) based on UiO-66(Zr) for effective SO 2 capture. Through systematic ligand functionalization with -OH, -NH 2 , -SO 3 H, and -(NH 2 ) 2 groups on terephthalic acid linker, we developed a series of MTV-UiO-66 materials with tailored pore environments and adsorption characteristics. UiO-66-NH 2 exhibited superior performance with an SO 2 uptake of 252.9 mL g −1 at 298 K and 1 bar. Ideal adsorbed solution theory (IAST) calculations demonstrated improved selectivity for SO 2 over N 2 (847) and CO 2 (31), surpassing that of the parent UiO-66. Dynamic breakthrough experiments further confirmed the practical viability of MTV-UiO-66 materials for SO 2 capture under both dry and humid (50 % RH) conditions, with UiO-66-NH 2 retaining a capacity of 30.73 mL g −1 in dry settings and exhibiting robust performance in moisture-rich environments. Grand Canonical Monte Carlo (GCMC) simulations and density functional theory (DFT) calculations provided molecular-level insights into the adsorption mechanisms, revealing that functional groups play a crucial role in modulating binding interactions through hydrogen bonding, dipole-dipole interactions, and spatial confinement effects. The computational binding energies corroborated the experimental isosteric heats of adsorption, validating the integrated experimental-computational approach.

Photocatalytic extraction hydrogen from water has been identified as a promising strategy for clean energy production. Constructing heterostructured photocatalysts is a prospective strategy to address the inherent problems of single semiconductor, including sluggish photogenerated charge/electron separation/transfer, fast recombination and interferior light adsorption, thereby contributing to enhanced photocatalytic hydrogen production from water splitting. Herein, NH 2 -UiO-66/Zn 0.5 Cd 0.5 S (NU/ZCS) heterostructured photocatalysts were prepared by growing NH 2 -UiO-66 (NU) on Zn 0.5 Cd 0.5 S (ZCS) for effective photocatalytic hydrogen generation. The optimized 20-NU/ZCS displays a distinguished photocatalytic hydrogen generation rate of up to 27.17 mmol g −1 h −1 , representing 1.71 times that of pure ZCS and exceeding most ZCS-based photocatalysts. The boosted photocatalytic activity can be stemmed from the intimate contact and the synergistic effect of NU and ZCS, which accelerate the separation/delivery and suppress the recombination of photogenerated electron/proton, and reinforce the light absorption. This study puts forward a promising method for fabricating ZCS-based heterostructured photocatalysts for efficient hydrogen generation.

The widespread use of acetaminophen (AP) has resulted in its frequent presence in pharmaceutical waste, posing ecological and health risks. To address this, a voltametric sensor based on a bimetallic UiO-66-NH 2 metal-organic framework incorporating Zirconium (Zr) and Cerium (Ce) was developed for sensitive AP detection. The incorporation of Ce 3+ not only introduced redox active sites but also reduced the particle size from 495-650 nm in (Zr)UiO-66-NH 2 to 230–365 nm in (Zr/Ce)UiO-66-NH 2 , increasing surface area and enhancing electrocatalytic activity. The combined synergistic effect of Zr and Ce significantly improved charge transfer and enhanced oxidation current response compared to the unmodified GCE. The sensor exhibited excellent electrocatalytic performance with a wide linear range (0.072–680 μM), high sensitivity (0.496 μAμM −1 cm −2 ), and a low limit of detection (0.024 μM). In addition, the sensor exhibited excellent selectivity against interfering species and maintained stable performance over 21 days. The sensor's practical applicability was validated by testing real environmental samples, achieving recovery rates of 97–103 %, and the results were consistent with those obtained using high-performance liquid chromatography (HPLC).

In this study, UiO-66/Cotton composite adsorbents with varied UiO-66 loadings were fabricated via a coupling strategy and applied for the adsorption of quinolone antibiotics (QNs)—including norfloxacin (NOR), ciprofloxacin (CIP), pefloxacin (PEF), and moxifloxacin (MFX)—from aqueous media. Under optimal conditions ( T = 298 K, pH=8.0, dosage=1 g/L, contact time=2 h, C 0 =100 mg/L), the maximum adsorption capacities followed the order: PEF (106.29 mg/g) > MFX (85.30 mg/g) > NOR (83.64 mg/g) > CIP (75.53 mg/g). Adsorption was enhanced by increased UiO-66 loading, though utilization efficiency decreased. Optimal performance was observed under pH 6.0–10.0 and in the presence of divalent cations. The process followed pseudo-second-order and Freundlich models, involving coordination, hydrogen bonding, electrostatic attraction, and π–π interactions. The UiO-66/Cotton composite (18.63 % loading) exhibited excellent reusability, maintaining 81.25 % removal efficiency for PEF after five cycles. Moreover, its solid–liquid separation and washing efficiency improved by approximately 40.1-fold and 44.3-fold, respectively, compared to pristine UiO-66. This work highlights the potential of MOF-based composite materials for effective QNs removal in water treatment applications.
