Membrane fouling is one of the major blockages toward the further sustained development of membrane technology . In this work, PVDF/NH 2 -MIL-88B(Fe) (PVDF/NM88B) membranes were prepared for the first time via one-step simple non-solvent induced phase conversion method. The PVDF/NM88B membrane shows an excellent separation performance (above 99.4%) and permeation flux (340–1970 L m −2 h −1 bar −1 ) towards different oil/water emulsions. Moreover, PVDF/NM88B membrane exhibits excellent antifouling performance with flux recovery ratio of almost 100% attributing to hydrophilicity and high photo-Fenton activity of NM88B. In addition, the membrane with good mechanical properties and recyclability shows great application potential in wastewater treatment . This work may shine a new light on the promising photo-Fenton self-cleaning prospect of Fe-based MOFs in constructing antifouling membranes for wastewater remediation and potential applications.

Solvent vapor-driven soft actuators have been seen as promising devices for human-environment interaction and gained considerable attention in recent years. Considering the limited types of response solvent and the lack of quantification, MOF/polymer intelligent soft actuators may be a potential candidate of the fabrication of the bio solvent-driven actuators. Thus, this paper present a multiple solvent-driven soft actuator based on MIL-88B/PVDF asymmetric film, and also the comparison to the analogs based on other MIL-88(Fe) series flexible MOFs (including MIL-88A, 88C and 88D) was made for the deformation-structure relationship and the solvent-driven mechanism investigation. The deformation behavior to various organic solvent (including methanol, toluene and chloroform) of the MIL-88(Fe)/PVDF composite films have been investigated, and the structure and composition of the MIL88(Fe) fillers and the composite films were also characterized by SEM, FT-IR, and XRD. Based on the above results, the MIL-88B/PVDF composite which shows the diversity of response objects and the fast deformation response to most of the organic solvents through the solvent swelling/adsorption of the MOF skeleton, was used to fabricate a monolayer soft film composed by MIL-88B, carbon black (CB) and PVDF, namely MIL-88B/CB/PVDF. The MIL-88B/CB/PVDF film not only realizes the excellent deformation-discolor dual-responsive to methanol atmosphere with the visible deformation which could being quickly achieved within 1s under 10 vol % methanol atmosphere and the maximum crimp angle being up to 558o within about 50 s, and also a wide color change range including six view angle-dependent high saturation color (red, orange, yellow, green, blue and purple), but also shows an approximate linear relationship to three of the organic solvents (methanol, toluene and chloroform) between the maximum curl angle and the solvent concentration. Furthermore, several smart devices have also been fabricated, including the methanol-driven bionic petals, worm robot, alertor and LIG sensor. Therefore, such soft composites of flexible MOF and polymer have great potential in bio-robot and this work may provide new design strategy for the MOFs/polymer smart materials.

Kanamycin (KANA) is a veterinary drug residue that is highly scrutinized in food safety testing. In this study, a metal-organic framework-based aptamer-nanoenzyme (NH 2 -MIL-88B(Fe)/CDs-Apt) was introduced for the dual-mode detection of KANA. NH 2 -MIL-88B(Fe) catalyzes the oxidation of 3,3′,5,5′-tetramethylbenzidine (TMB) by H₂O₂ to form blue ox-TMB, thereby enabling colorimetric detection. As a fluorescence quencher, NH 2 -MIL-88B(Fe) quenches the fluorescence of CDs via photogenerated electron transfer (PET) or fluorescence resonance energy transfer (FRET) mechanisms. The detection limits were 0.716 fM (fluorescent) and 0.709 fM (colorimetric), respectively. The proposed aptasensor was successfully applied to the detection of KANA in eggs, honey, and lake water. This aptasensor demonstrates high sensitivity and accuracy, as well as broad application potential.

The development of efficient strategies to promote spatial charge separation is a promising way for the improvement of photocatalytic performance. Herein, a novel surface oxygen vacancy (OVs) modified Bi 2 MoO 6 /MIL-88B(Fe) heterostructure (BMO/M88) was exemplified by a facile two steps solvothermal method to demonstrate synergistic promotion of bulk & interface charge separation. Due to the existence of OVs and the construction of heterostructure, the Bi 2 MoO 6 /MIL-88B(Fe) composites exhibited significant enhancement of visible-light responsive range and possessed more efficient bulk & interface charge separation. This novel Bi 2 MoO 6 /MIL-88B(Fe) composites exhibited high visible light photocatalytic performance toward dye pollutant rhodamine B (RhB) and model colorless pollutant bisphenol A (BPA) photodegradation , and the possible Type II heterojunction mechanism of photocatalysis process was investigated. This work not only provides a novel pathway for design of MOFs-based heterojunction with surface OVs defect modification but also offers a strategy for significantly enhanced bulk & interface charge carriers separation.

TiO 2 @NH 2 -MIL-88B(Fe) heterostructures (TMFe-x) were successfully synthesized and used in an efficient sunlight-driven reduction towards Cr(VI) in a neutral aqueous media. Further, the prepared TMFe-x heterostructures exhibited higher photocatalytic activity when compared with those exhibited by pure TiO 2 and NH 2 -MIL-88B(Fe) under simulated sunlight irradiation. The optical TiO 2 modification content was determined to be 10 wt.% (TMFe-b), with 98.6% Cr(VI) being converted to Cr(III) within 35 min using ammonium oxalate as the hole scavenger at pH = 7. In neutral conditions, the kinetic rate constant (0.0878 min −1 ) was five times larger than the published values. Additionally, the photocatalytic performance of TMFe-b was maintained and Fe leaching was observed to be negligible after the completion of four reaction cycles. The superior photocatalytic property can be attributed to the high photoelectron-hole separation and migration efficiency. Subsequently, TMFe-b achieved Cr(VI) reduction under neutral conditions by capturing hydrogen from the water molecules or the hole scavengers. The photoelectrons and superoxide radicals were the main active species. Furthermore, TMFe-b was able to efficiently eliminate various pollutants through photocatalytic oxidation and reduction. This study suggests a novel strategy for the preparation of environmentally stable and efficient MOF-based photocatalysts to efficiently eliminate various pollutants. Further, there is a huge potential for the practical application of this technology to water purification .

Herein, a highly efficient Z-scheme SnS 2 /MIL-88B (Fe) (SnSFe) heterojunction was successfully synthesized to use both as photocatalysts and persulfate (PS) activator for ibuprofen (IBP) degradation. Flower-liked SnS 2 was uniformly loaded on MIL-88B (Fe), and SnSFe retained the original polyhedral morphology of MIL-88B (Fe). The highest removal of IBP was achieved in the presence of SnSFe with 0.5% SnS 2 (SnSFe0.5). Characteristic results and density functional theory calculations demonstrated that the enhanced degradation of IBP was due to the difference in Fermi energy levels of SnS 2 and MIL-88B (Fe) leading to electrons transferred from SnS 2 to MIL-88B (Fe), and Sn O bond was formed in SnSFe. , OH and O 2 − were the main active species in SnSFe0.5/PS/visible light system. Z-scheme heterojunction of SnSFe was constructed to propose the degradation mechanism. This research revealed that the synergism of photocatalysis and PS activation using SnS 2 /Fe-based MOFs composites possessed great potentials in wastewater remediation.

A magnetically recyclable and efficient catalyst for biodiesel synthesis was fabricated by confining the Brønsted ionic liquid 1,4-butanediyl-3,3′-bis(3-sulfopropyl) imidazolium dihydrogensulfate in an amino-functionalized magnetic metal–organic-framework composite (Fe3O4@NH2-MIL-88B(Fe)) through a simple and efficient strategy via the amino groups. The catalyst was systematically characterized, proving ionic liquid was grafted in the amino-functionalized carrier, and the catalyst was spindle-shaped with superparamagnetism (7.2 emu/g). The prepared catalyst with high acidity (1.76 mmol H+ g–1) exhibited good catalytic activity in biodiesel synthesis from oleic acid and ethanol with a yield of 93.2%, optimized by Box-Behnken response surface methodology. The fine catalytic performance of the catalyst was mainly due to the combination of the characteristics of the ionic liquid and the structure of Fe3O4@NH2-MIL-88B(Fe). Moreover, the catalyst was recycled without significant loss of activity after being used for six runs and could be magnetically separated in magnetic force without obvious mass loss.

Dual-mode sensor integrates fluorescence/colorimetric detection for cross-validated acetamiprid monitoring. • Synergistic recognition by MIP and aptamer enhances specificity in complex food matrices. • The MIL-88B (Fe) was used as a dual-signal probe triggered by PPi. • The integration of smartphone-based colorimetric readout and machine learning enhances field applicability. • Achieves ultra-sensitive detection with high recovery in real samples. This work presents a smartphone-integrated, fluorescence/colorimetric dual-mode sensing platform that combines fluorescence and colorimetric detection with support vector regression (SVR) for monitoring of acetamiprid in food. The system employs a sandwich-structured mechanism using MIPs/Fe 3 O 4 as capture probes and aptamer-functionalized MIL-88B(Fe) as bifunctional signal probes. Uniquely, pyrophosphate (PPi) triggers the disassembly of MIL-88B(Fe), synchronously releasing fluorescent 2-aminoterephthalic acid ligands and Fe 3+ ions, which subsequently catalyze Prussian blue formation for colorimetric readout. Furthermore, the integration of smartphone imaging and a SVR mode allows for intelligent translation of RGB color features into precise acetamiprid concentrations, facilitating rapid analysis. The biosensor demonstrates exceptional performance with detection limits of 41.0 pg mL −1 (fluorescence) and 45.0 pg mL −1 (colorimetric), maintaining high specificity in complex matrices. Successful application in fruit and vegetable extracts confirmed its practical utility, offering a sensitive, cross-validation, and field-deployable strategy for food safety monitoring.

A one-pot PEG-modified MIL-88B(Fe) coating was developed for breath aldehydes. • The 10% PEG/Fe³⁺ ratio gave the highest responses for all five aldehydes. • Detection limits were 0.018–0.030 ng mL⁻¹ with precision below 10%. • The coating retained 87.9–93.9% response after 110 extraction cycles. A polyethylene glycol (PEG)-modified MIL-88B(Fe) composite was synthesized by a one-pot route and evaluated as a coating for headspace solid-phase microextraction (HS-SPME) coupled with gas chromatography–mass spectrometry (GC–MS) for the determination of five C6–C10 aldehydes. Among the materials prepared at PEG/Fe 3+ molar ratios of 0, 5, 10, and 15%, PEG 10 @MIL-88B(Fe) produced the highest peak areas for all five aldehydes. Characterization by powder X-ray diffraction, Fourier-transform infrared spectroscopy, scanning electron microscopy, thermogravimetric analysis, X-ray photoelectron spectroscopy, and N 2 adsorption–desorption analysis supported PEG modification while retaining the structural characteristics of MIL-88B(Fe). Under the optimized conditions, the developed method provided enrichment factors of 2563–15,562. Calibration curves were linear over 0.1–500 ng mL –1 (R 2 = 0.9911–0.9988), with LODs of 0.018–0.030 and LOQs of 0.059–0.099 ng mL –1 of calibration solution (liquid-standard-equivalent). Intra-day, inter-day, fiber-to-fiber, and batch-to-batch RSDs were 3.9–5.9%, 4.2–8.2%, 4.0–9.8%, and 5.3–10.1%, respectively. The method showed limited interference from representative breath volatile organic compounds, with relative responses of 89.30–92.02%, while matrix effects ranged from 94.7% to 104.1%. After 110 extraction/desorption cycles, the coating retained 87.9–93.9% of its initial response. The PEG 10 @MIL-88B(Fe)-coated SPME fiber was applied to exhaled-breath samples, with spike recoveries of 87.2–105.5%, supporting its applicability to the trace determination of C6–C10 aldehydes in exhaled breath.

Metal organic frameworks (MOFs) possess excellent post-modification characteristics, high specific surface area, diversity of skeleton composition and pore tunability, have been increasingly applied in membrane modifications. In this work, NH 2 -MIL-88B(Fe) (NM88B) was first fixed onto polyvinylidene fluoride (PVDF) membrane by polyethyleneimine (PEI) through a vacuum-assisted self-assembly process, and the deposited NM88B was subsequently grafted with perfluoroalkyl polyethoxyacetic acid (FPEOAA) via a condensation reaction to realize the surface modifications. The modified membranes (named as N1F x ) showed improved hydrophilicity and underwater-oleophobicity. In addition, very high pure water flux (up to 9403 L‧m −2 ‧h −1 ) was obtained for the N1F x membranes due to the high porosity of introduced NM88B. In the dead-end filtration experiments of n -hexadecane-water emulsion, the optimum membrane N1F20 showed a good oil rejection rate (98.3%) and high permeation flux (667 L‧m −2 ‧h −1 ) which is approximately seven times of the pure PVDF membrane, indicating that the surface-modified membranes had excellent permeability and good separation performance. Even after four filtration cycles of oil-water emulsion, the rejection rate maintained higher than 97%, showing good reusability. Furthermore, the study found that N1F20 had certain acid and alkaline resistance and great potential for engineering applications.

The presence of the antibiotics in the wastewater has posed a huge risk to aquatic life and human health. It is a great significance to develop an effective technology to treat the antibiotics-containing wastewater. In this study, a series of g-C 3 N 4 /NH 2 -MIL-88B(Fe) composite photocatalysts are synthesized through a simple one-step method. The structure and optical properties of prepared photocatalysts are detected by X-ray diffraction (XRD), field emission scanning electron microscope (FESEM), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), UV–Vis absorption spectra (UV–Vis DRS), photoluminescence (PL) spectroscopy and transient photocurrent techniques, respectively. FESEM and TEM show that MOF is uniformly dispersed in petaloid g-C 3 N 4 . The uniform dispersion of Fe-MOFs in the heterojunction composites increases the specific surface area ( S BET ) of g-C 3 N 4 , which results in a great adsorption property for the nanocomposite. The capture experiment shows that • O 2 − and h + are the main active substances in ciprofloxacin (CIP) degradation. These prepared composite photocatalysts exhibit excellent CIP photodegradation activity under visibly light irradiation with an apparent rate constant of 0.0127 min − 1 (3.74 times as the rate of single component). The remarkable catalytic performance can be ascribed to the fact that the g-C 3 N 4 /NH 2 -MIL-88B(Fe) heterojunction inhibits the recombination of photoinduced electron–hole pairs and improved the visible light absorption.

In this study, magnetic biochar bead ((AB + MIL-88)-C) was prepared by pyrolyzing MIL-88B(Fe) loaded alginate beads. The Fenton-like activity of (AB + MIL-88)-C was then investigated through activating peroxymonosulfate (PMS) for bisphenol A (BPA) degradation in water. The results demonstrated that (AB + MIL-88)-C exhibited superior BPA degradation capability (k = 0.160 min −1 ) than pristine MIL-88B(Fe) and alginate bead derived catalysts (k = 0.089 & 0.008 min −1 ), in which non-radical mechanisms including singlet oxygen ( 1 O 2 ) and electron transfer process contributed over 98 % of BPA degradation. Moreover, PMS consumption rate by (AB + MIL-88)-C during whole BPA degradation process was very low. Consequently, the non-radical pathway dominated oxidation system with low PMS consumption rate could maintain its activity regardless of the fluctuation of environmental parameters and water matrices. Besides, it was further demonstrated that the reaction system exhibited high degradation selectivity in which those pollutants with electron donating groups were more inclined to be degraded. Meanwhile, the degradation rate (ln k ) of respective pollutant in the reaction system correlated well (R 2 = 0.97) with their highest occupied molecular orbital position. This study provides a strategy for the development of non-radical oxidation systems with high pollutant degradation efficiency, stability and selectivity.
