Developing a green and economically viable approach for the direct synthesis of metal-organic frameworks (MOFs) catalysts with multifunctional active sites remains the key step for their applications in heterogeneous catalysis field. Herein, we report a green (aqueous solutions), mild (90 °C, atmospheric pressure), and modulated hydrothermal (MHT) approach to synthesize UiO-66-type MOFs catalysts with acid–base bi-functional sites, which were obtained via the coordination of monosodium 2-sulfoterephthalate and 2-aminoterephthalic with zirconium (Zr) ions. More importantly, a series of acid, base and acid–base catalysts with varied acid–base strengths can be readily prepared, by simply varying the ratio of organic ligands for preparing MOFs. The synthesized catalysts were characterized and their performances in glucose dehydration to produce 5-hydroxymethylfurfural (5-HMF) have been evaluated. The developed approach in this work has clearly depicted a roadmap for the facile synthesis of MOFs catalysts to facilitate their potential use in acid–base catalysis.

A series of ordered mesoporous Nb x W (8 − x) oxides with tunable Nb/W ratio were successfully synthesized by evaporation-induced self-assembly method. The mesoporous structure, morphologies, surface chemical state, and acidic properties of these catalysts were fully characterized by low-temperature sorption of N 2 , small-angle and wide-angle XRD, TEM, Raman, XPS, and Py-IR. It was shown that the Nb x W (8 − x) oxides created large amounts of Lewis as well as Brønsted acid sites, which promoted the isomerization of glucose to fructose followed its dehydration to 5-hydroxymethylfurfural (HMF). Mannose was also formed via the epimerization of glucose. Of them, the mesoporous Nb 4 W 4 exhibited the best catalytic activity with a comparatively low E a about 90.2 kJ/mol and good stability in aqueous medium. The kinetic behavior revealed that Lewis acid sites facilitated to glucose-to-fructose isomerization while Brønsted acid sites promoted the dehydration of fructose to form HMF.

The catalytic transformation of furfuryl alcohol and hexose into value-added chemicals have been investigated with a series of polymer-based catalysts including poly(styrenesulfonic acid) (PSS), graphite oxide-doped poly(styrenesulfonic acid) (PSS-GO), and graphite-doped poly(styrenesulfonic acid) (PSS-C). It is found that the selective conversion of furfuryl alcohol to methyl levulinate (MLE) was successfully performed with PSS as the catalyst, in which a 96.4% yield is attained in methanol solvent. Moreover, the efficient dehydration of d -fructose to produce 5-hydroxymethylfurfural (HMF) has also been achieved using PSS-GO as the catalyst, where a 76.5% yield of HMF was obtained in N -methylpyrrodinone solvent. The effects of reaction temperature, time and solvent were investigated. Furthermore, the used catalysts have been respectively characterized by XRD, TG, FTIR, SEM and TEM techniques to reveal the physical properties and structures of these polymeric catalytic materials.

Solid phosphoric acid (SPA) catalysts with different carriers were prepared and used for catalytic fast pyrolysis of poplar wood to produce levoglucosenone (LGO), a valuable anhydrosugar derivative that can be used in various organic synthesis applications. Pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS) experiments were performed to evaluate the catalytic capabilities of these catalysts under different reaction conditions. The results indicated that SPA catalyst prepared with the SBA-15 carrier exhibited the best catalytic capability for selectively producing LGO. Both the catalytic pyrolysis temperature and catalyst-to-biomass ratio affected the pyrolytic products greatly. The maximal LGO yield reached as high as 8.2 wt% from poplar wood, obtained at the pyrolysis temperature of 300 °C and the catalyst-to-biomass ratio of 1. The by-products during the catalytic pyrolysis process were mainly acetic acid (AA) and furfural (FF). In addition, the SPA catalyst possessed better catalytic capability than the liquid phosphoric acid (H 3 PO 4 ) catalyst to produce LGO.

The core–shell FeNPs@Pt shows excellent catalytic activity and stability. • Selective detection via thiol–Michael addition without enzymes or aptamers. • The color development is rapid and convenient, taking only 150 s to complete. • The suppression–recovery mechanism amplifies the signal and enhances sensitivity. In this study, we propose an innovative Acrylamide (AA) detection platform based on platinum-coated magnetic iron nanoparticles (FeNPs@Pt). The introduction of a platinum shell not only preserves the intrinsic catalytic properties of FeNPs but also significantly enhances their structural stability and catalytic activity. Compared with traditional antibody–aptamer-based detection methods, this platform employs a thiol–Michael addition reaction combined with a nanocatalyst-mediated cascade colorimetric process. This approach overcomes key limitations of antibody–aptamer technologies, such as high cost and operational complexity, enabling rapid and low-cost detection of AA. The mechanism involves a specific Michael addition reaction between AA and 2,2′-(ethylenedioxy)diethanethiol (EDT), which mitigates the inhibitory effect of EDT on the catalytic activity of FeNPs@Pt. Subsequently, the addition of 3,3′-dimethylbenzidine (TMB) triggers a colorimetric reaction within 150 s, rendering the result visible to the naked eye. This sensing platform exhibits a linear response over the range of 1–200 μM, with a detection limit as low as 0.63 μM. Notably, the FeNPs@Pt–EDT–TMB-based colorimetric detection platform not only provides an efficient and low-cost method for acrylamide detection but also offers an innovative solution for on-site food safety monitoring, demonstrating significant application potential.

The inherent flammability and insufficient ultraviolet (UV) protection of regenerated cellulose fibers limit their functional applications. Inspired by the natural polyphenol–polysaccharide synergy in plants, a lignin-derived boron-containing phenolic network (Lig-BPF) was incorporated into a cellulose spinning system and then coordinated with Zn 2+ to fabricate Cellulose/Lig-BPF@Zn fibers. Compared with pristine cellulose fibers, Cellulose/Lig-BPF@Zn increased the char residue at 800 °C from 13.72% to 30.35% under N 2 atmosphere, and reduced the peak heat release rate by 43.03%. The limiting oxygen index increased from 17.2% to 31.5%, and still remained 29.1% after 20 laundering cycles. TG-FTIR analysis showed an 88.56% reduction in total volatile release intensity, while Raman analysis confirmed an increased degree of graphitization, as evidenced by a decreased I D /I G value from 3.59 to 2.55. Furthermore, the UV protection factor increased from 11.42 to 128.82, and remained 109.74 after durability testing. Mechanistic analyses demonstrate that lignin-derived aromatic domains, boron-containing structures and Zn-coordinated species regulate cellulose pyrolysis and promote the char formation. This work develops a sustainable strategy for converting natural lignin into a bio-based flame retardant that simultaneously improves the flame retardancy and UV protection performance of regenerated cellulose fibers, providing a phosphorus-free and eco-friendly approach for preparing multifunctional carbohydrate-based fibers.

The precise regulation of Fe spin states and correlation with catalytic activity remain a challenging frontier in heterogeneous catalysts. Herein, we report an Fe-based spinel oxide with iron atoms solely occupying octahedral sites, prepared from layered double hydroxide (MgFe-LDH) precursor. The Fe spin configuration has been precisely regulated from low- to high-spin states by controlling the calcination temperature. The catalyst prepared at 700 °C (MgFeO-700) exhibits a medium-spin Fe state, which optimally balances reactant activation and six-member-ring transition state formation, delivering superior catalytic transfer hydrogenation (CTH) performance with a stable 95% yield in the transformation of furfural (FF) to furfuryl alcohol (FOL). Combined in situ DRIFTs and density functional theory (DFT) calculations reveals that the hybridization strength of Fe 3d and O 2p orbitals governs the spin-dependent reaction kinetics. The moderate d-p orbital coupling in the medium-spin state reduces the six-membered-ring transition state barrier, driving higher catalytic efficiency This work uncovers a direct structure–activity correlation between Fe spin state and catalytic performance, providing a general strategy for spin-state engineering of Fe-based oxides toward economical and robust catalysts.

The changes in metabolic profiles of honey during long-term room temperature storage were studied. • Untargeted and targeted metabolomics approaches reveal changes in components of stored honey. • Phenolic acids decrease and furfurals increase during long-term room temperature storage. The performance stability during honey processing and storage is critical to evaluating honey quality and safety. Previous research mainly focused on the impact of heat processing on honey quality, while the molecular changes in chemical composition and the underlying mechanisms of honey during long-term room-temperature storage are unclear. Herein, the honey samples stored at 25 °C–30 °C for 0–24 months were prepared, and the differential metabolite profile of the prepared honey was analyzed using an HPLC-QTOF-MS-based untargeted metabolomics. Changes in characteristic compounds are presented as the degradation of six phenolic acids (gallic acid, p -hydroxybenzoic acid, vanillic acid, syringic acid, p -coumaric acid, and ferulic acid) and the generation of four furfurals (5-hydroxymethylfurfural, 2-furaldehyde, 2-furyl-methyl ketone, and 5-methylfurfural). The variations in characteristic compounds of eight randomly selected batches of honey samples with different storage durations are consistent with the above. This study comprehensively investigated the changes in chemical composition during 24-month storage of acacia honey, demonstrating the significant impact of room-temperature storage on honey quality and providing a reference for honey quality control.

Six highly unsaturated diimidazole ionic liquids (ILs) were synthesized and applied to catalyze the condensation of furfural into furoin. The effects of solvents and reaction conditions on the reaction were also investigated. Results showed that the δH(C-2) chemical shift of the imidazolium ring could reflect the catalyst’s catalytic performance. CH2Cl2 facilitated the deprotonation of the ILs and product separation, leading to the highest furoin yield. While the presence of 10% acetone could enhance contact between the catalyst and furfural, thereby increasing the yield. RSM, ANN, and SVR demonstrated the reliability and accuracy of the experimental results. The kinetic calculation was consistent with the observed rapid completion of the reaction under mild conditions. What’s more, energy-level calculations revealed that the nucleophilic reaction with the second furfural molecule to form furoin constitutes the rate-determining step. This work is expected to provide valuable guidance for catalyst design and process optimization.

Lignocellulosic biomass, which consists primarily of
cellulose,
hemicellulose, and lignin, is a promising renewable feedstock for
producing high-value biobased amines. In this study, an integrated
chemobiocatalytic strategy was developed to synthesize furfurylamine
from corncob using a newly formulated deep eutectic solvent, [Bet][FA][LA],
that provides both catalytic and solubilizing functions. Under optimized
conditions, corncob was efficiently converted into furfural, which
was subsequently aminated by recombinant Escherichia coli BM-AlaDH coexpressing an ω-transaminase
and alanine dehydrogenase. The whole-cell catalyst enabled in situ
regeneration of L -alanine, thereby reducing amine-donor
requirements and improving biocatalytic efficiency. Integration of
[Bet][FA][LA]-mediated chemocatalysis with whole-cell biocatalysis
converted corncob into furfurylamine in [Bet][FA][LA]. The biocatalytic
amination system could convert biomass-derived 5-hydroxymethylfurfural
(320 mM) and vanillin (20 mM) into the corresponding amines in yields
of 95.4% and 91.0%, respectively. This work establishes a sustainable
route for converting lignocellulose-derived aldehydes into value-added
biobased amines and advances the comprehensive valorization of lignocellulosic
biomass.

A three-channel sensor array based on Au@Pt NPs was constructed. • Au@Pt NPs with dual-function characteristics was designed. • Discrimination of light aroma-type Baijiu (LAB) was achieved. • Different years, production processes, price gradients, and adulterated were analyzed. • This method highlighted simple to operate, rapid in detection. The development of light aroma-type Baijiu (LAB) industry proposes a growing need for developing rapid and accurate discrimination method for the quality control of LAB. This study innovatively constructed a dual-mode three-channel sensor array based on the gold/platinum nanoparticles (Au@Pt NPs) with surface engineering. In this case, two colorimetric sensor channels based on ascorbic acid/para-aminophenol-chloroauric acid-nanozyme (AA/ pAP-HAuCl₄-Au@Pt NPs) and one fluorescent sensor channel based on nanozyme‑hydrogen peroxide- o -phenylenediamine (Au@Pt NPs-H₂O₂-OPD) were established. Experimental results demonstrate the colorimetric and fluorescence mode can accurately quantify four organic acids and three aldehydes in Baijiu, respectively. Samples including 17 different years and 9 different production processes of basic liquors of LAB, 48 different price gradients of commercial LAB, and adulterated LAB were analyzed. Discrimination with an accuracy exceeding 96% by Linear Discriminant Analysis, Hierarchical Cluster Analysis, and leave-one-out cross-validation was achieved. The dual-mode three-channel sensor array is characterized by simplicity, rapidity and accuracy, providing a new idea for the quality discrimination and market regulation of Baijiu.

Modulating the electrocatalytic interface is key to efficiently converting 5-hydroxymethylfurfural (HMF) into 2,5-furandicarboxylic acid (FDCA). Herein, a NiCo( OH ) x /NiCoMoO 4 heterojunction electrocatalyst is constructed. The high-valence Mo 6+ substrate acts as an electron regulator, creating electron-deficient Ni sites and promoting the formation of active Ni 3+ species for HMF oxidation. Operando analysis and distribution of relaxation times (DRT) studies confirm that the Mo 6+ substrate enhances charge transfer and mass transport. This special electronic structure directs selective aldehyde group activation, steering the reaction along the HMFCA pathway. The obtained catalyst achieves a 91.4% FDCA yield with 96% Faradaic efficiency at 1.4 V vs. RHE. This work demonstrates a dual modulation strategy via high oxidation state substrate for efficient biomass conversion.
