As climate change exacerbates the global water crisis, desalination is becoming vital for acquiring clean water from plentiful brackish and seawater sources. Notably, interlayer thin-film nanocomposite membranes used in reverse osmosis and nanofiltration stand out as key innovations. These advanced membranes are drawing interest due to their remarkable performance, attributed mainly to their capability to create thinner selective layers in thin-film composite structures. This study introduces a novel methodology combining UiO-66-(COOH) 2 with tannic acid complexes as an interlayer to enhance filtration performance for reverse osmosis application. Various characterization methods were employed to validate this innovative approach. The techniques confirmed both the unique morphology of the membrane and the impact of tannic acid UiO-66-(COOH) 2 complexes on the polyamide membrane. Additionally, filtration tests showed notable enhancements in membrane performance, with salt permeance dropping from 0.47 LMH for the control membranes to an impressive 0.28 LMH for the membrane with tannic acid UiO-66-(COOH) 2 complexes. Permeance also increased substantially from 1.08 to 1.65 LMH/bar. A five-day stability test conducted under high-pressure conditions highlighted the durability and excellent properties of the membranes. This research showcases a promising and inventive strategy for improving the efficacy of desalination membranes, which has the potential to transform water purification technologies.

Heterogeneous catalysis is highly desirable for the self-condensation of cyclohexanone, an important step in producing intermediates for fine chemicals and polymers. Conventional methods often rely on toxic reagents and long reaction times, limiting their industrial viability. In this study, Zr- and Hf-based metal–organic frameworks (UiO-66 and NUS-6) were developed as efficient, environmentally friendly catalysts for the self-condensation of cyclohexanone. Their high surface area and hierarchical porosity, combined with bifunctional Brønsted and Lewis acid sites introduced through partial linker substitution, enable excellent catalytic performance. UiO-66(Zr) achieved 81 % conversion in 6 h and 98 % in 48 h, while NUS-6(Zr) reached 85 % and 86 % under the same conditions, with high selectivity toward the desired dimer products. The catalysts also showed strong thermal stability and reusability, maintaining activity at elevated temperatures. This work demonstrates a sustainable catalytic pathway for cyclohexanone dimerization, avoiding corrosive chemicals while offering both efficiency and selectivity.

CNF biomacromolecules were developed as green MOF modulators. • Defective nanosized MOF with enhanced fluorescence activity was successfully prepared. • ICT effect modulation enables sensitive organophosphorus pesticide detection. • Food-grade multifunctional fruit coating was constructed via cellulose self-assembly. • The work offers new insight into cellulose high-value use in food & agricultural safety. Biomass-derived polysaccharide macromolecules have emerged as sustainable, biocompatible functional materials for green agricultural and food applications, owing to their tunable surface groups, self-assembly properties and environmental friendliness. MOFs hold great sensing potential for their superior structural properties, while pure MOFs have critical flaws (severe agglomeration, low mass transfer, poor specificity/stability) in practice, limiting their broader deployment. To address this challenge, a general strategy for structural regulation of UiO-66-OH using green and sustainable carboxylated cellulose nanofibrils (CNFs, a typical linear polysaccharide biomacromolecule) as the sole biogenic modulator and nano-template was proposed. Driven by the competitive coordination and nano-templating effects of CNFs, the defective nanosized UiO-66-OH features abundant active sites and amplified fluorescence signals, modulating the intramolecular charge transfer (ICT) effect for sensitive pesticide detection. In the presence of the target analyte, a distinct fluorescence enhancement was achieved, with an LOD of 1.40 μg/kg (far below the international glyphosate MRL of 0.1 mg/kg in grains) and robust anti-interference against 17 common interferents. Additionally, leveraging the self-assembly properties of CNFs polysaccharide, a food-grade multifunctional fruit coating was fabricated via spray coating, enabling in-situ visual monitoring of pesticide residues and fruit freshness, pesticide degradation, and long-acting fruit preservation. This work offers a rational material design insight and technical support for high-value utilization of cellulose-based biomacromolecules, as well as the green governance of agricultural pesticide residues and high-efficiency fruit preservation.

Lactoferrin (LF) is widely used in healthcare and food industry as an antibacterial and functional additive. Its complex structure makes rapid detection challenging. Here, an antibody-free molecularly imprinted (MIP) electrochemical sensor was developed using Ti 3 C 2 MXene and UiO-66-NH 2 nanomaterials to construct an imprinted layer for the rapid and efficient detection of LF in dairy products. The incorporation of Ti 3 C 2 MXene@UiO-66-NH 2 @PPy (TiPU) enhanced the surface area and conductivity of the material, and MIP provided specific cavities that were precisely matched to LF in terms of size, shape, and chemical functional groups. Molecular docking simulations confirmed the reliability of LF MIP compound formation. The synthesized nanocomposites (MIP-TiPU) were characterized by various methods, including their morphology, structure, and electrochemical properties. The MIP-TiPU modified electrochemical sensor displayed an outstanding sensing performance for LF detection, with a wide linear response range from 5 ng/mL to 500 ng/mL and a low detection limit (0.98 ng/mL).

In order to improve the activity and reusability of β-xylosidase, the β-xylosidase mutant S160N-R333H (R333H) which could convert notoginsenoside R1 to ginsenoside Rg1 and xylose was immobilized on the metal-organic framework (MOF) UiO-66-NH 2 . The physical and biochemical properties of immobilized β-xylosidase ( [email protected] 2 ) were studied in detail. The results showed improved performances, i.e. the high immobilization yield of 93% and recovery activity of 192.8%, better stability under acidic or trypsin-containing conditions, the higher activity in the reaction containing ions , and the improved catalytic efficiency (was 1.37-fold than that of free R333H). Importantly, the ginsenoside Rg1 yields remained more than 80% after six recycles in McIlvaine buffer and pure water. The UiO-66-NH 2 could catalyze xylose dehydration to produce furfural and the yield reached 69%. Thus this study provides a promising method for production of bioactive or platform chemicals via continuous conversion of xyloylated substrates using nanocatalyst synthesized by β-xylosidase and MOF.

Benzydamine hydrochloride (BDH) is a kind of nonsteroidal anti-inflammatory drugs for the treatment of inflammation. However, research on removing BDH from the environment has not attracted attention. Herein, a green deep eutectic solvent (DES) as functional monomer and magnetic metal organic frameworks (MUiO-66-NH 2 ) as supporter help to form more effective recognition sites and easy separation properties in polymerization procedure of the surface imprinted polymer (DES-MMIP). The performance of novel DES-MMIP for the selective removal of the template (BDH) in water was characterized and evaluated. The equilibrium experiment results showed that the maximum adsorption capacity of BDH can reach 41.18 mg g −1 , and fast adsorption equilibrium was obtained within 30 min. Due to the participation of magnetic MUiO-66-NH 2 and DES, the prepared DES-MMIP had excellent separability, and the adsorption capacity towards template (BDH) was 1.4–2.6 times that of other commercial adsorbents (PS-DVB, HLB, silica and zeolite). The DES-MMIP combined with UV-via was successfully applied to remove BDH from eight environmental samples. Additionally, the DES-MMIP adsorbent can be reused 5 times and still maintain excellent recovery. This work provides a promising method for preparing an efficient adsorbent for the fast separation and selective removal of BDH in the environmental field.

In order to enhance the photoelectric conversion efficiency of a photoanode and broaden its light absorption range, a ZnIn 2 S 4 /UiO-66/TiO 2 /Ti composite photoanode was developed. The maximum photocurrent density of the prepared photoanode is 2.56 mA cm −2 at 1.2 V (versus SCE), which is 1.79 times higher than that of ZnIn 2 S 4 /TiO 2 /Ti. The rhodamine B (RhB) removal rate, short-circuit current density and maximum power density of a photocatalytic fuel cell (PFC) constructed with the ZnIn 2 S 4 /UiO-66/TiO 2 /Ti photoanode and a Cu cathode are 98.01%, 0.22 mA cm −2 and 16.97 μW cm −2 respectively. The enhancement of the PFC performance is mainly attributed to the extremely good energy band matching and nano-size interface contact between ZnIn 2 S 4 and UiO-66. The existence of UiO-66 can be as an electronic transmission bridge, which not only facilitates the rapid transfer and utilization of photogenerated electrons, but also improves the adsorption ability of the photoanode for RhB molecules.

A novel BiOI-incorporated NH 2 -UiO-66 composite photocatalyst, NH 2 -UiO-66@BiOI, was prepared using an in-situ successive ion-insertion method. The in situ grown BiOI nanosheets exhibited an ultrathin structure and were uniformly dispersed on NH 2 -UiO-66. The formation of tight heterojunctions, characteristics of enhanced visible light absorption and availability of abundant exposed active sites facilitated the efficient activation of peroxymonosulfate and the rapid degradation of Bisphenol A in water (12 min). Surprisingly, the photocatalyst maintained a fast degradation rate of Bisphenol A under the interference of different conditions. The research explored the charge transfer pathways and radical species between the heterojunction components, indicating that the heterojunction type of the NH 2 -UiO-66@BiOI was Z-scheme. In addition, the degraded intermediate components and high mineralization rate indicated that Bisphenol A was deeply degraded. In conclusion, this study synthesized metal–organic framework-based photocatalysts through a simple preparation method, which has potential application value in the rapid degradation of bisphenol A.

Sulfadiazine (SDZ), as a broad-spectrum pharmaceutical antibiotic, has drawn extensive attention owing to its wide application and persistence. Photocatalytic oxidation has been considered as a high-efficiency and environment-friendly technology for degrading organic contaminants. A novel BiOI/UiO-66 p-n heterojunction (BiU- x ) was fabricated via the in-situ deposition of p-type BiOI nanoplates on n-type UiO-66 octahedrons with the aid of a controlled precipitation method. The optimizing BiU-9 heterojunction exhibited a remarkably enhanced photocatalytic efficiency in removing SDZ, in which the SDZ (5 mg/L) removal efficiency over BiU-9 (0.5 g/L) reached nearly 100 % within 90 min of visible light irradiation. The influence of some important environmental factors (e.g., photocatalyst dosage, pH, co-existing inorganic anions and real sunlight irradiation) were systematically investigated. Such improvement mechanism should be assigned to the following three factors. Firstly, the introduction of narrow gap semiconductor BiOI effectively improved photo adsorption capacity. Secondly, benefiting by the large specific surface area, the involvement of UiO-66 contributed to boost the surface active sites. Most importantly, an internal electric field at the contact interface between UiO-66 and BiOI accelerated the separation of photo-generated electrons and holes. Furthermore, · O 2 − and photo-generated holes were identified as the dominating reactive species accounting for the SDZ removal. The decomposition pathways of SDZ and ecotoxicities of the intermediates were analyzed via combing with LC-MS/MS and T.E.S.T theoretical calculation. This work may provide an alternative way for enhanced photocatalytic performance of MOF-based materials through construction of p-n heterojunction with bismuth-based semiconductors.

Metal-organic frameworks (MOFs) have been considered as promising nanofillers to fabricate mixed matrix membranes for water treatment. However, manipulating distribution of MOFs nanoparticles in the membrane matrix remains a great challenge. In this study, UiO-66 was firstly coated by magnetic Ni via an in-situ reduction reaction, and then incorporated into polyethersulfone (PES) membrane matrix to prepare PES-Ni@UiO-66 membrane. The magnetic Ni allowed to manipulate the distribution of magnetic Ni@UiO-66 in the phase-inversion process by an external magnetic field. The hydrophilic Ni@UiO-66 can be pulled onto membrane surface by the magnetic force, endowing the prepared membrane with rather higher hydrophilicity. The prepared membrane exhibited superior water permeability with a pure water flux of 611.5 ± 19.8 L·m −2 ·h −1 and improved antifouling performance. Moreover, benifiting from photocatalytic activity of the exposed Ni@UiO-66 on membrane surface, the obtained PES-Ni@UiO-66 membrane demonstrated excellent photocatalytic self-cleaning ability with a flux recovery rate (FRR) higher than 95% under UV irradiation. Analyzing by extended Derjaguin-Landau-Verwey-Overbeek (XDLVO) theory indicated that the improved antifouling performance could be attributed to less attractive or even repulsive interaction between the prepared membrane and pollutants. This work provided valuable guidance for structural regulation and development of high-performance MOFs-based membranes for water treatment.

Zirconium-based metal–organic frameworks (Zr-MOFs) have been considered as prospective materials for the degradation of nerve chemical warfare agents (CWAs) but show poor catalytic performance toward blister agents. Moreover, the powder issues and the poor adsorption capability also remain as the major challenges for the application of Zr-MOFs in practical CWA detoxification. Herein, a series of defected granular UiO-66-NH2 metal–organic gels are synthesized via adjusting the amount of added concentrated hydrochloric acid for the decontamination of 2-chloroethyl ethyl sulfide (2-CEES), a sulfur mustard simulant. The half-life of 2-CEES decontaminated by defected granular UiO-66-NH2 metal–organic gels can be shortened to 7.6 min, which is the highest reported value for MOFs under ambient conditions. The mechanism of decontamination is that the amino group on the linkers in UiO-66-NH2 MOGs undergoes a substitution reaction with 2-CEES to yield 2-(2-(ethylthio)ethylamino)terephthalic acid, which is less toxic and fixed in the frameworks. The recycling test corroborates that the granular UiO-66-NH2 xerogels possess good stability and reusability. Static adsorption and desorption tests show that UiO-66-NH2 xerogels possess a high 2-CEES vapor adsorption capacity of 802 mg/g after exposure for 1 d and only 28 wt % desorption capacity after air exposure for 7 d. The dual function of ultrafast degradation and high adsorption capability provide a firm foundation for using UiO-66-NH2 xerogels as a future protection media.
