The persistent accumulation of organic pollutants in aquatic environments poses serious risks to ecosystems and public health. In this study, a double Z-type photocatalyst BiOBr/BiOI/MIL-53(Fe)-min was successfully fabricated by a two-step solvothermal-hydrothermal synthesis method. Characterization revealed tightly stacked BiOBr/BiOI nanosheets uniformly coating rod-like the 2-methylimidazole-modified metal–organic framework MIL-53(Fe) (MIL-53(Fe)-min), forming a core-shell structure with intimate interface contact. The formation of a unique double Z-type heterojunction significantly inhibited the recombination of photogenerated electron-hole pairs and optimized the charge carrier transfer pathway. Meanwhile, the surface stacked catalyst nanosheets not only improve the utilization efficiency of photons, but also greatly increase the contact area between active radicals and reactants. Under visible light irradiation, BBF-20 composite photocatalyst demonstrated a tetracyclines (TC) degradation rate of 90.6% within 100 min, with 80.3% of its activity retained after five cycles. Notably, polyethylene terephthalate (PET) microplastics achieved 56% weight loss after being treated by BBF-20 for 8 h. The main active species during degradation process were determined through quenching experiment and EPR tests. HPLC-MS analysis proposed the possible degradation pathways for TC and PET microplastics. Based on experimental results, a double Z-type heterojunction mechanism was proposed. This work presents a novel strategy for designing efficient photocatalysts to degrade antibiotics and microplastics in complex aquatic environments.

Fluorinated MOFs material F-MIL-101 simply synthesized by hydrothermal method. • A gel polymer electrolyte that can fully dissociate LiTFSI. • The t Li + of FM-10 is 119% higher than M-10. • The FM-10 formed a LiF-rich SEI layer on the lithium anode. • LFP||Li cells achieve excellent rate and cycling characteristics. Development of an attractive inorganic filler plays a vital role in effectively enhancing the comprehensive performance of a polymer electrolyte. Herein, a fluorine-functionalized metal organic framework (fluorinated MIL-101, F-MIL-101) is intentionally designed as filler for fabricating a novel composite polymer electrolyte (FM-10). Spectroscopic analysis and density functional theory calculations reveal that F-MIL-101 exhibits high effective dissociation and transportation of Li + for LiTFSI salt. Notably, the F functional group hinders anion transport, thereby giving the FM-10 GPEs a high transfer number of 0.81 for a uniform deposition of Li + on the Li anode surface. Furthermore, the F group of F-MIL-101 is greatly favorable for the formation of a stable LiF-rich solid electrolyte interface (SEI) on the Li anode surface during cycling to hinder the uninterrupted reaction. Consequently, the FM-10 GPEs demonstrates an excellent stable Li anode with a long cycle-life of 600 h in Li||Li cell at 2 mA cm −2 . More importantly, the FM-10 GPEs assembled LiFePO 4 (LFP) || Li cell exhibited an initial discharge capacity of 120.5 mAh g −1 at a high 6C-rate and a retention of 98.68% after 300 cycles, implying that the F-MIL-101 filler shows great potential as a strategy for fast charging, long cycle life, and high safety SSLMBs.

The bifunctional photocatalyst CDs@NH 2 -MIL-125(Ti), carbon nanodots (CDs) encapsulated in NH 2 -MIL-125(Ti), was constructed in situ by a simple and convenient low-temperature calcination approach, which exhibited great capacity in NO removal (at air level) and H 2 evolution simultaneously under visible-light irradiation. The NO removal rate of CDs@NH 2 -MIL-125(Ti) (10 mM) reached 53%, which was 28.4% higher than pristine NH 2 -MIL-125(Ti). Moreover, the H 2 production rate was 5820.95 μmol g −1 , which was 5.34 times higher than that of original NH 2 -MIL-125(Ti). The corresponding optical and electrical performances of CDs@NH 2 -MIL-125(Ti) characterized by UV–Vis, UCPL, ESR, and in situ DRIFTS , etc. indicated that the encapsulated CDs uniformly dispersed in the pores of NH 2 -MIL-125(Ti) could improve the visible light utilization via the up-conversion effect and photosensitization, and serve as an electron-receiver to significantly prolong the lifetime of the photogenerated charge carriers, thus enhancing the photocatalytic performance. The results revealed that fabricating CDs with metal-organic frameworks (MOFs) could be an available strategy for us to boost the photocatalytic NO elimination and H 2 evolution activity simultaneously.

To mitigate the ecological risks of trifluralin (TFL) from volatilization, photolysis, and leaching, a stimuli-responsive composite, TFL/CMC-GEL/MIL-101(Fe), was developed by encapsulating MIL-101(Fe) within a carboxymethyl cellulose–gelatin semi-interpenetrating hydrogel. The composite enhanced light stability of TFL by 1.5 times, reduced leaching by 17.8%, and extended soil retention beyond 14 days, minimizing groundwater contamination. In addition, the herbicidal activity of TFL/CMC-GEL/MIL-101(Fe) against Portulaca oleracea L. and Setaria viridis (L.) P. Beauv. were 95% and 94%, respectively, which was equivalent to TFL technical. Meanwhile, this herbicidal delivery system markedly enhanced crop safety, with rice seed germination rising from 13% under TFL technical alone to 36%. The dual-network design enables on-demand herbicide release by integrating MIL-101(Fe)-mediated protection with hydrogel-based stimuli responsiveness, effectively mitigating herbicide migration in the environment and offering a sustainable plant protection platform.

This study develops a visible-light-driven heterogeneous Fenton-like system for the efficient degradation and detoxification of the persistent fluoroquinolone antibiotic gatifloxacin (GAT) in water. Three Fe-based metal–organic frameworks (MIL-53(Fe), MIL-88A(Fe), and MIL-101(Fe)) were synthesized and systematically evaluated as catalysts in a visible-light/H2O2process. The three MOFs were systematically characterized, and a comparative analysis was conducted to elucidate how their structural differences influence catalytic performance. Among three MOFs, MIL-88A(Fe) exhibited superior photocatalytic activity, stability, recyclability, and low energy consumption in the visible-light-driven photo-Fenton process, which was attributed to its favorable structural and photo-induced redox properties. Under the optimal conditions (pH 7.2, H2O2dosage of 1.2 mL·L−1, and catalyst loading of 0.1 g·L−1), 95.6% of GAT was degraded within 90 min. Radical scavenging experiments demonstrated that hydroxyl radicals (•OH) dominated the oxidation process. Based on intermediate identification, plausible degradation pathways were proposed, accompanied by a pronounced reduction in the ecological risks of transformation products. Furthermore, toxicity assays revealed that both the antibacterial activity and acute toxicity of the treated solutions were significantly alleviated. Overall, the Light/MIL-88A(Fe)/H2O2system offers an effective and sustainable strategy for the removal and detoxification of fluoroquinolone antibiotics from aquatic environments.

Catalytic tar reforming is a pivotal technology for upgrading syngas quality during sewage sludge gasification. In this study, a series of Ni-modified carbon-based catalysts (x%NiFe/C) were synthesized using MIL-100(Fe) as a precursor to investigate the impact of Ni-loading on the catalytic performance for tar reforming. Detailed characterizations, including XRD, XPS, Raman, and NH 3 -TPD, revealed that the introduction of Ni species significantly tailored the physicochemical properties of the catalysts. Specifically, the 3.3%NiFe/C catalyst exhibited the optimal specific surface area and pore structure, facilitating efficient mass transfer. Characterization results confirmed the formation of Ni-Fe alloy, which not only modulated the surface electronic density to optimize acidity but also enhanced the dispersion of active sites. The interaction between Ni and Fe species effectively promoted the cleavage of C-C and C-H bonds in tar molecules while suppressing carbon deposition. Consequently, the 3.3%NiFe/C catalyst demonstrated superior catalytic activity and stability in the two-stage microwave-assisted gasification reforming process, achieving a syngas yield of 555 mg/g·SS, a tar conversion rate of 82.9%, and an H 2 concentration of 73.8 vol%. After ten cycles, the H 2 yield and concentration remained as high as 28.0 mmol/g·SS and 68.2 vol%, respectively. This work provides mechanistic insights into the design of MOF-derived carbon-supported catalysts for efficient SS gasification.

Carbon dots endowed MIL-53(Fe) with four synergistic functions. • A dual-mode aptasensor enabled accurate pathogen detection. • A closed-loop strategy integrated detection with safe pathogen elimination. • A paper-based assay achieved rapid visual food safety screening. The increasing prevalence of foodborne pathogens has created an urgent need for integrated strategies on combining rapid on-site detection with safe inactivation. In this study, a multifunctional aptamer-modified CDs@MIL-53(Fe) nanocomposite was developed to construct a closed-loop management platform integrating target recognition, dual-mode signal transduction, and in situ photothermal-chemodynamic sterilization. This nanocomposite uniquely combined four functionalities within a single material: fluorescence emission, oxidase/peroxidase-mimicking activity, photocatalytic reactive oxygen species generation, and efficient photothermal conversion. After aptamer functionalization, the platform enabled both colorimetric and fluorescence dual-mode detection. Using Listeria monocytogenes as a proof-of-concept model, detection limits of 6.01 CFU/mL (colorimetric) and 61.38 CFU/mL (fluorescence) were obtained with the proposed method, within a linear range of 10 1 –10 6 CFU/mL. Importantly, the sensing mechanism allowed easy adaptation to other pathogens by simply replacing the aptamer. After detection, the same platform achieved in situ synergistic sterilization (>99.5%), and the used test strips could be safely discarded. Validation in chicken breast and milk samples, along with successful translation to a paper-based device, demonstrated the practical application potential of this universal pathogen management strategy in food safety supervision and disease prevention.

Although MIL-101(Fe) has a homogeneous distribution of active metal sites, the relatively low stability of its coordination bonds limits its potential for application, especially in harsh environments. Here, a novel lanthanum-doped MIL-101(Fe)-NH 2 @mesoporous SiO 2 yolk-shell (LMFN-YS) material, synthesized by green water-etching, has effectively improved the adsorption capacity and stability of MIL-101(Fe)-NH 2 . Compared to traditional acid-base etching methods, water etching offered a more co-friendly and cost-effective approach to producing yolk-shell structures. Due to the mesoporous protective shell of mesoporous SiO 2 and more exposed active sites, the yolk-shell materials showed a faster adsorption rate (30 min) and a larger uptake capacity (240.0 mg P/g) than those of MIL-101. The material also exhibited broad range of pH stability from 2 to 10 and displayed good cyclic regeneration ability, with a removal efficiency of 75.9 % after three cycles. Additionally, it demonstrated excellent selectivity towards various coexisting anions such as Cl − , NO 3 − , SO 4 2− , CO 3 2− and HCO 3 − at diverse ionic strengths ranging from 0.001 to 1 M. The superior performance of L 1 MFN-YS (yolk-shell materials of La: Fe = 1:1) was attributed to a combination of factors, including ligand exchange between La(Fe)-OH and phosphates, Lewis acid-base interaction and electrostatic attraction. Additionally, high phosphate removal performance was observed in the real petrochemical wastewater (initial concentrations of 5.48 mg P/g) with a residual effluent concentration of 0.05 mg P/L, which was below the A-level standard of phosphate effluent in China (0.5 mg/L). This work provides a green method for preparing yolk-shell materials with improved ability to treat phosphate wastewater.

The construction of a tightly contacted heterojunction consisting of multi-components is proven to be one of the effective strategies to promote the photogenerated charges separation and to develop high-efficient photocatalysts in hydrogen evolution . Herein, a ternary hollow heterostructure of ZnS/ZIS/In 2 S 3 has been fabricated by using a binary MOF@MOF (ZIF-8@MIL-68(In)) as the precursor, and an in-situ sulfurization of ZIF-8@MIL-68(In) is controlled to optimize the photocatalytic performances. The resulting samples are signed as Z@M- t , where the t is pointed to the sulfurization time being varied from 4 h to 48 h. It’s shown that the hierarchical and hollow architecture is formed for Z@M- t , and with the reinforced light harvest ability in both UV and visible light regions. In the subsequent visible-light-induced photocatalytic hydrogen generation, the optimized Z@M-24 manifests significantly improved hydrogen evolution rate of 607.34 μmol g -1 h −1 , which values are evidently higher than that by the single MOF and binary ZIF-8@MIL-68(In) heterostructure. The electrochemical analyses and the electron paramagnetic resonance (EPR) spectrum were analyzed to clarify the charge transfer routes and the enhanced photocatalytic mechanism, in which the contribution of each metal sulfide is also discussed. Finally, the good photocatalytic stability and reusability of Z@M-24 heterostructure are also represented, which define the structure superior brought by the effective heterojunction based on the in-situ sulfurization strategy of binary ZIF-8@MIL-68(In), and determine their prospect applications in the efficient H 2 production under visible light irradiation.

Concerns about food safety have been arisen due to the improper use of chemicals in aquaculture. Malachite green (MG) has attracted attention because of its illegal usage and its potential negative impacts on the environment and public health. Surface-enhanced Raman scattering (SERS) platforms coupled with different SERS substrates have been employed for rapid analysis of MG residues in food. However, the most commonly used SERS substrates were non-reusable and showed limited detection sensitivity. In this study, a novel SERS substrate with a good recyclability and a high sensitivity was prepared by electrostatically assembling together a metal–organic framework material called materials of institute lavoisie-100(Fe) (MIL-100(Fe)) and Au NPs. The lowest detectable concentration of MG was 10 −13 M based on the optimal substrate. The SERS sensor was applied for the detection of the trace MG in fish pond water, which was accomplished with the correlation coefficients R 2 = 0.991–0.996 in a concentration range of 10 −6 –10 −13 M. Moreover, MIL-100(Fe)/Au was recycled at least five times, realizing a “detection to degradation”, showing great potential for food contamination monitoring due to its distinguished performance.

Lithium metal batteries are considered promising contenders for the next generation of high energy density batteries. However, lithium metal anode with inhomogeneous lithium deposition in liquid electrolyte causes the uncontrolled growth of lithium dendrites. Owing to the high dielectric constant, thermal stability and electromechanical stability of polyvinylidene fluoride, we design a novel gel polymer electrolyte consisting of porous polyvinylidene fluoride polymer matrix, liquid electrolyte, ethylene carbonate and MIL-125 (Ti) (Ti8O8(OH)4(BDC)6, BDC = 1,4-benzene dicarboxylate) for facilitating Li+ transfer and alleviating the growth of lithium dendrites. The high dielectric constant environment facilitates the dissociation of Li+, and the porous polymer matrix structure accommodates more Li+ for fast transfer. Ethylene carbonate reduces the crystallinity of the polymer matrix and improves the ionic conductivity. MIL-125 (Ti) nanoparticles with surface area and uniform micropores improve toughness for enhancing mechanical property, and synergistically promote the Li+ transfer for building stable interfacial phase to alleviate the growth of Li dendrites. Therefore, the gel polymer electrolyte has high ionic conductivity of ∼1.50 × 10−3 S cm−1 at 25 °C, and quasi-solid-state Li/LiFePO4 battery has high discharge capacity of 153.5 mAh g−1 after 250 cycles at 25 °C and 0.3 C.
