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.

This study investigated the effects of moderate germination (4°C, 65%–75% RH, sprout length less than 1 cm) on the physicochemical properties and antioxidant capacity of raw and aged black garlics. Moderate germination significantly increased the contents of fructose, glucose, alliin, allicin, total flavonoids in raw garlic, which improved by 33.68%, 31.47%, 5.61%, 38.21%, and 90.91%, respectively. It also resulted in the obvious rise in alliin, total polyphenols, and total flavonoids in black garlic aged from germinated raw garlic, and rose by 29.01%, 26.96%, and 51.22%, respectively. The antioxidant capacity of germinated raw garlic and its aged black garlic was also significantly improved. While germination promoted the formation of 5-hydroxymethylfurfural (5-HMF) (increased by 55.47%) and inhibited the production of acrylamide (decreased by 49.91%) in aged black garlic. It did not significantly affect the color of raw and aged black garlics. Moderate germination is an excellent strategy to improve the nutritional contents and antioxidant capacity of raw and aged black garlics, which displays a promising alternative for developing functional foods from moderately germinated raw garlic and its aged product.

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 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.

A highly conjugated biobased liquid HPE monomer was fabricated from HMF. • The benzimidazole motif HPE contributes to a relatively mild curing behavior. • The HPE endows the resin with favorable mechanical properties and dimensional stability. • The HPE networks showed good solvent resistance and shape memory. • This strategy provided a tractable biocomposite fabrication. A novel bio-based epoxy monomer (HPE) bearing a rigid benzimidazole-furan skeleton was synthesized from 5-hydroxymethylfurfural (5-HMF). The activation energy for HPE-derived networks was relatively lower than that of the DGEBA counterparts, indicating favorable curing conditions. The cured HPE-thermosets exhibited exceptional mechanical properties. For instance, HPE/APB achieved good tensile strength (105.67 ± 13.43 MPa), flexural strength (125.43 ± 16.65 MPa), and impact strength (17.99 ± 1.10 kJ m −2 ). Moreover, the thermomechanical investigation also suggested its advantageous storage modulus of 3.55 GPa at 30 °C, which surpassed the petroleum-based DGEBA counterparts. Notably, HPE-networks displayed unique dimensional stability with a thermal expansion coefficient ranging from 87 to 115.4 ppm °C −1 below 200 °C. In contrast to DDM-cured thermoset, APB-cured networks also favored decreasing dielectric constant and loss. On the whole, the APB hardener outperformed the DDM in most cases. Furthermore, glass fiber-reinforced HPE composites demonstrated 90.8% peeling off in DMF under microwave-assisted conditions, making sustainable fiber recycling possible. This work provides a promising strategy for HMF-related renewable epoxy resins. Download: Download high-res image (147KB) Download: Download full-size image

ZnIn 2 S 4 -based photocatalysts have attracted considerable attention in biomass valorization owing to their tunable band structures and abundant surface reaction sites. However, the aqueous-phase selective photooxidation of 5-hydroxymethylfurfural (HMF) to 2,5-diformylfuran (DFF) remains highly challenging due to the insufficient O 2 activation, substrate mineralization, and competitive coupling side reactions. Herein, a single-atom Sn-doped ZnIn 2 S 4 photocatalyst (Sn-ZIS) was constructed. Systematic characterizations confirm that Sn species are atomically dispersed and incorporated into the ZnIn 2 S 4 lattice through Sn-S coordination. Under aqueous-phase reaction conditions, Sn-ZIS achieves 88.7% HMF conversion, 80.5% DFF selectivity, and 93.3% C equilibrium, higher than those of ZnIn 2 S 4 and many reported aqueous-phase photocatalytic systems. The better performance of Sn-ZIS is mainly attributed to the synergistic regulation of the band structure and local electronic structure induced by Sn incorporation. The optimized band structure moderately weakens the oxidative ability of photogenerated holes, thereby reducing HMF mineralization to CO 2 . While the regulation of the local electronic structure promotes O 2 adsorption and activation to generate superoxide radicals, it simultaneously facilitates DFF desorption from the catalyst surface. Synergy between the two functions drives the selective conversion of HMF into DFF. This work demonstrates the potential of single-atom doping for enhancing aqueous-phase biomass photooxidation and provides a rational strategy for designing efficient ZnIn 2 S 4 -based photocatalysts.

In this study, we present a straightforward synthesis
strategy
to prepare transition metal sulfide electrocatalysts supported on
sulfonated carbon nanotube-chitosan-derived carbon aerogel. Highly
dispersed Ni 3 S 2 @CNT, Cu 7 S 4 @CNT, and Co 4 S 3 @CNT were successfully fabricated
and applied for 5-hydroxymethylfurfural (HMF) electrooxidation to
2,5-furandicarboxylic acid (FDCA). Among them, Co 4 S 3 @CNT exhibited remarkable electrocatalytic activity, delivering
a current density of 100 mA cm –2 at a low potential
of 1.367 V (vs RHE) while attaining 99.82% HMF conversion, 99.97%
FDCA selectivity and a Faradaic efficiency of 83.75%. Electrochemical
measurements revealed that Co 4 S 3 @CNT possesses
an electrochemical active surface area (ECSA) of 0.781 μF cm –2 , which is higher than those of Ni 3 S 2 @CNT and Cu 7 S 4 @CNT, implying an increased
population of active sites and enhanced catalytic activity. In-situ
Raman spectroscopy reveals that Co 4 S 3 @CNT undergoes
a progressive reconstruction from Co(OH) 2 to CoOOH under
anodic conditions, with CoOOH formation being significantly delayed
in the presence of HMF, confirming its role as the active phase. Density
functional theory (DFT) calculations further indicate that the excellent
performance of Co 4 S 3 @CNT originates from the
lowest energy barrier (1.84 eV) for the rate-determining catalyst
activation dehydrogenation step, coupled with its pronounced charge-polarization
capability that facilitates HMF preactivation. This work gives a promising
design approach for developing efficient nonprecious metal electrochemical
catalysts toward biomass valorization.

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.

Developing precious-metal-free catalysts for the selective hydrodeoxygenation of biomass-derived 5-hydroxymethylfurfural (HMF) to 2,5-dimethylfuran (DMF) is critical yet challenging. Herein, a series of non-noble metal Co@CN-T catalysts were designed and fabricated, which can efficiently catalyze the selective hydrogenolysis of HMF to DMF under mild reaction conditions of 140 °C, with the selectivity of the target product reaching as high as 99%. The Co-N x coordination active sites serve as Lewis acid sites, which can preferentially activate the C=O bond in HMF. Such selective activation promotes the effective hydrogenolysis of the intermediate 2,5-bis(hydroxymethyl)furan (BHMF) to 5-methylfurfuryl alcohol (MFA), reduces intermediate accumulation, and thus guarantees high selectivity toward DMF. In addition, the Co@CN-T catalysts also exhibited excellent stability, and their catalytic activity remained stable without obvious attenuation after five consecutive cycles of reaction. This study offers theoretical insights into the use of non-noble metal catalysts for the hydrodeoxygenation of renewable biomass to produce chemical feedstocks.

MOF-templated strategy fabricates highly dispersed Cu x Ni 2-x /CeO 2 catalysts. • Cu 1.2 Ni 0.8 /CeO 2 achieves 100% BHMF yield under mild reaction conditions. • Cu-O V interfacial sites induce vertical adsorption for C=O selective activation. • Ni-promoted H spillover boosts hydrogenation efficiency. Efficient utilization of biomass is a cornerstone of green chemistry and sustainable development. 5-Hydroxymethylfurfural (5-HMF) constitutes a pivotal biomass-derived platform molecule which selective hydrogenation into 2,5-bis(hydroxymethyl)furan (BHMF) plays a crucial role in the development of bio-based materials and fine chemicals. Conventional monometallic catalysts, however, are often constrained by an intrinsic trade-off between activity and selectivity and tendencies toward particle sintering and deactivation. To address these challenges, a metal–organic-framework (MOF) precursor was employed in a self-sacrificial templating route to fabricate highly dispersed, oxygen vacancies-tunable, bimetallic Cu x Ni 2–x /CeO 2 catalysts. By integrating comprehensive physicochemical characterization with in-situ spectroscopies, a systematic investigation was conducted to examine the effects of the Cu/Ni ratio and oxygen vacancy (O V ) concentration on 5-HMF hydrogenation were systematically investigated to elucidate structure–activity relationships. The results demonstrate that the Cu 1.2 Ni 0.8 /CeO 2 catalyst achieves an optimal balance between O V and metal site distribution, enabling nearly complete 5-HMF conversion and exclusive selectivity toward BHMF. Interfacial synergy facilitates Ni-mediated H 2 dissociation and hydrogen spillover to Cu sites, while the O V selectively adsorbs and activates the carbonyl of HMF, suppressing furan-ring hydrogenation and other side reactions. Compared with prior reports, this work highlights the decisive roles of O V and bimetallic interfaces in promoting substrate-selective adsorption, active-hydrogen supply, and side-reaction suppression. This strategy advances the high-value conversion of biomass platform molecules and provides a conceptual foundation for the rational design of green catalysts.
