Adsorption, as a widely used water treatment method, has gradually revealed many drawbacks. Advanced oxidation processes, as emerging water treatment technologies, address some of the limitations of adsorption. However, designing bimetallic catalysts that are easy to synthesize and prevent metal ion leaching is crucial for activating peroxymonosulfate (PMS). To address these issues, this study designs a biochar reactor structure made by simple treatment and composite formation using wood as the base material. Biochar serves as an adsorbent to concentrate PMS and pollutants while preventing metal leaching. Additionally, Co Cu nitrogen-doped graphite carbon derived from metal-organic frameworks (MOFs) is encapsulated within the structure to efficiently activate PMS. The system achieved 100 % methylene blue degradation within one minute. Even after five cycles, it maintained a 95 % removal rate and exhibited excellent degradation performance across a wide pH range, proving its practical applicability. Furthermore, the synergistic pathway and transfer channels involved in adsorption-PMS activation were elucidated through various characterizations to reveal the underlying mechanism. This study aims to provide a novel material with adsorption and catalytic capabilities for the removal of organic pollutants through a simple and easily scalable synthesis method.

Odor–induced saltiness enhancement has become an effective way of reducing salt consumption, as recommended for health purposes, without compromising consumer acceptability. In this study, the odorants in fried white mushrooms were investigated using solvent-assisted flavor evaporation, chromatography–mass spectrometry, and gas chromatography–olfactometry. A total of 40 odorants were identified, with 27 exhibiting relative odor activity values ≥0.1. Among them, 8 compounds were considered relating to saltiness by gas chromatography–olfactometry/associated taste analysis. Sensory analysis revealed that 2,5-dimethylpyrazine, 2-ethyl-3,5-dimethylpyrazine, 3-(methylthio)propanal, and 1-octen-3-one significantly enhanced the saltiness perception of 0.3 % NaCl solution ( p < 0.05). The electroencephalography confirmed compared with NaCl solution (0.3 %), the brain response energy values were increased significantly by adding 3-(methylthio)propanal and 1-octen-3-one ( p < 0.05). This research explored the possibilities of mushroom-derived odorants in enhancing perceived saltiness and provided methodological supports for odor-induced taste enhancement research.

Electrocatalytic production of 2,5-furandicarboxylic acid (FDCA) from 5-hydroxymethylfurfural (HMF) is a sustainable and clean pathway for harvesting both value-added chemicals and green hydrogen (H 2 ). Herein, B, N doped porous carbon supporting Co (Co/BN-C) with abundant pyridinic N-B species was constructed via a one-pot method using chitosan as precursors, which was further applied for the paired electrocatalysis of an HMF oxidation reaction (HMFOR) and H 2 evolution reaction (HER). H 3 BO 4 as a templating agent could increase the specific surface area of the catalyst and expose more active sites for the HMFOR. Meanwhile, H 3 BO 4 also acted as a B source to dope heteroatoms in the carbon matrix, creating surface defects and thus improving electrical conductivity. Besides, B, N-doped carbon substrate induced the electron deficiency of Co nanoparticle, resulting in the strong adsorption of HMF on the catalyst surface via the interactions between the aldehyde group/furan ring of HMF and the catalyst. Consequently, the Co/BN-C catalyst exhibited remarkable performance with a high HMF conversion (> 99%) and selectivity to FDCA (> 98%) and remained high activity after 8 cycles.

Milk tea, a cultural convention in part regions of the United Kingdom, India, Sri Lanka and China, modulates polyphenol-induced astringency and bitterness while improves flavor. Existing studies mainly focused on the health impacts of milk protein-tea polyphenol interaction, with less attention on the flavor modulation. The present study systematically investigated the impact of milk proteins on aroma compound release in black tea infusions. After adding milk, the release of volatile compounds in the black tea infusion was significantly suppressed, among which the release of aroma compounds such as benzaldehyde is particularly obvious. Multi-spectroscopic analyses combined with molecular docking revealed that volatile compounds, such as benzaldehyde would bind to the hydrophobic regions of casein and be stabilized by hydrogen bonds, which induced static quenching of casein fluorescence. Furthermore, competitive binding assays demonstrated that theaflavins occupied the binding sites of benzaldehyde and (E,E)-2,4-heptadienal, facilitated the aggregation of milk protein and thereby promoted the release of aroma substances. The experimental results provided a theoretical basis for the mechanism of milk tea aroma and established a framework for the preservation of milk tea flavor.

Lignocellulosic biomass possesses significant potential as a carbon-based renewable energy source. Fast pyrolysis can convert biomass into valuable derivatives, though achieving high selectivity for target compounds remains a challenge. In this study, acid-leached slag (ALS) derived from spent Al 2 O 3 -based catalysts was employed as a catalyst to investigate its effect on the pyrolysis products of water hyacinth (WH). Under optimal conditions of a WH/ALS ratio of 1:3 at 500 °C, the bio-oil yield reached 70.81 wt%, and furfural yield achieved 97.37 area% with a concentration of 83.96 mg/mL. This enhancement is attributed to the synergistic catalytic activity of Brønsted and Lewis acid sites on ALS, which substantially improves the directional selectivity toward furfural. Concurrently, biochar undergoes aromatization, forming aromatic ring structures that promote graphitization, while the proportion of combustible syngas rises to 99.84%. Additionally, N-containing heterocyclics from the bio-oil are redistributed into the biochar (as graphitic-N, pyrrolic-N, and pyridinic-N) and syngas. This study demonstrates an effective strategy for simultaneously valorizing WH and ALS, offering a novel approach for producing high-value chemicals through catalytic pyrolysis of lignocellulosic biomass.

Context The application of Raman spectroscopy for detecting furfural dissolved in transformer oil represents a highly promising approach for online monitoring for assessing the aging process of transformer insulating paper. Combining density functional theory (DFT) computational simulations with experimental measurements, the characteristic Raman spectra of the furfural molecule were analyzed, and the assignments of its key vibrational modes were determined. Furfural molecular clusters of varying sizes were constructed to investigate the effect of intermolecular hydrogen bonding forces on the Raman signals. The Raman spectra of furfural in solvents with different dielectric constants were measured. Comparison with simulation results indicates that enhanced solvent polarity induces a rearrangement of the electron cloud around the C=O bond, an increase in dipole moment, and a narrowing of the band gap. These changes thereby result in a red shift of the Raman peak position and an enhancement of scattering intensity. This work deepens the understanding, at the microscopic level, of the aggregation behavior of furfural in transformer oil and the influence of the solvent environment on its Raman characteristics. Methods All quantum chemical calculations were conducted using the Gaussian 16W program, and molecular structures were built using GaussView 6.0. The ground-state geometry of furfural was optimized using DFT with the B3LYP functional. The solvent effect caused by solvents with different dielectric constants was simulated and calculated using the polarized continuum model (PCM) of furfural. For all computations, the 6-311+G (2d, p) basis set was employed for C, H, and O atoms.

Cyclopentanone (CPO) as a key raw material has been widely applied in spices, pharmaceuticals, and sustainable fuels. The catalytic conversion of biomass-derived furfural (FAL) to CPO meets the requirements of sustainable development goal but still be challenging because of the relatively low selectivity of CPO in the complex tandem catalytic processes. Herein, a Ni/WO 3 -H 2 catalyst presents a cooperative interface that possesses hetero-valent interface of Ni 0 (metallic) and Ni 2+ (interfacial NiWO 4 ), oxygen vacancies (O v ), and acid sites simultaneously was prepared and applied in the tandem hydrogenative ring-rearrangement of FAL to CPO. Under 160 °C and 3 MPa of initial hydrogen pressure, the catalyst achieved 90.3 % furfural conversion and 96.9 % selectivity to CPO, with a turnover rate of 4.26 mmol·g cat ⁻¹ ·h⁻¹ . Moreover, the Ni/WO 3 -H 2 catalyst demonstrated excellent stability and recyclability. Further investigation on reaction mechanism shows that the synergy of each active site, Ni 0 , Ni 2+ (NiWO 4 ), oxygen vacancies (O v ), and acid sites, promotes the conversion of FAL to CPO and effectively avoids the undesired side reaction. Accordingly, a multi-site cooperative mechanism is proposed: FAL hydrogenates to FOL on Ni 0 sites; acid sites rearrange FOL to HCP, which dehydrates at O v sites to CPE; ultimately, CPE is hydrogenated to CPO on Ni hetero-valent interface.

In this paper, a mode-mismatched photothermal lens liquid sensing system using a distributed feedback quantum cascade laser (DFB-QCL) as the excitation source for the detection of furfural in insulating oil. The mid-infrared absorption spectrum of furfural in an insulating oil matrix was characterized by Fourier transform infrared (FTIR) spectroscopy, identifying the optimal absorption peak at 1703 cm⁻¹ . Temperature and current tuning of the DFB-QCL were performed on pure oil and a 500 mg/L furfural/insulating oil sample to determine the optimal temperature and current values, ensuring maximum sensitivity during light excitation of the oil samples. Frequency-domain investigation of the PTL signal response revealed an exponential decrease in signal amplitude with increasing modulation frequency. The PTL signal amplitude exhibited a linear correlation with furfural concentration in the insulating oil. The sensing system has a low limit of detection (LOD) for furfural in insulating oil down to 5.9 mg/L, with a linear concentration range extending up to 500 mg/L. This method does not require pretreatment of the oil sample and can be used for real-time in-situ monitoring.

The conversion of furfural (FF) to cyclopentanone (CPO) via selective hydrogenation-rearrangement represents a crucial route for sustainable, high-value valorization of renewable biomass feedstocks. In this study, carbon dots (CDs) were utilized as both a reducing and a dispersing agent for the one-pot green photoreduction synthesis of PdAg bimetallic catalysts supported on CDs (Pd x Ag y /CDs) in aqueous phase. Among the catalysts with varying Pd-to-Ag molar ratios, the Pd 0.5 Ag 1 /CDs catalyst demonstrated exceptional performance, achieving 100 % FF conversion and 93.3 % CPO selectivity within 4 h at 200 °C. The superior activity is attributed to a synergistic effect between the acid sites on the CDs and the PdAg alloy, which facilitates the rearrangement of the intermediate furfuryl alcohol (FA). Mechanistic studies, including calculations of the free energy barriers for elementary steps from FA to 4-hydroxy-2-cyclopentenone, revealed a ring-opening pathway for the furan methyl carbocation, which dramatically reduces the reaction energy barrier to 47.1 kJ/mol from 195.8 kJ/mol of the Piancatelli pathway. This work not only presents an efficient and green catalyst for FF upgrading but also highlights the promising application of CDs in advanced catalytic systems for circular economy-driven chemical production.

Utilizing lignin as a complete substitute for petroleum-derived phenol to synthesize non-toxic lignin-based resin adhesives with bio-based aldehydes holds substantial significance for advancing sustainable development in the wood-based panel industry. Nevertheless, the poor bonding strength, toughness, and water resistance of phenol-free lignin-based resins hinder their practical application. Herein, inspired by the hyperbranched structures of loose connective tissue, borate chemistry of plant cell walls, and Fe 3+ -phenol coordination bonds of mussel foot proteins, a tough, strong, water-resistant, and multifunctional lignin-based resin adhesive is fabricated through introducing phenylboronic acid-grafted hyperbranched polyamide (HBPB), Fe 2 (SO 4 ) 3 , and furfural into the lignin matrix to construct lignin-based supramolecular networks. HBPB-induced microphase separation structure disperses mechanical stress and inhibits crack evolution. Meanwhile, hyperbranched phenylboronic ester bonds optimize the crosslinking strength and cohesive force. Furthermore, Fe 3+ -phenol coordination bonds facilitate the formation of hydrophobic structures to prevent moisture intrusion. Consequently, the fracture toughness, bonding strength, and wet bonding strength of the resin are 23.4, 6.1, and 5.4 times higher than those of the unmodified resin. Moreover, the resin exhibits excellent flame retardancy, recyclability, degradability, biosafety, and plant-growth promotion after degradation. This biomimetic design provides an effective approach to develop tough, strong, water-resistant, and multifunctional bio-based adhesives.

Efficient conversion of biomass-based platform molecules into high-value derivatives is recognized as one formidable challenge in biomass upgrading. In this work, a one-pot deep eutectic solvents-assisted solvothermal method was developed for the modification of the commercial Pt/C catalysts by introducing a secondary metal (M = Sn, Bi, Ge, Sb, Pb). The structural and electronic properties of the catalysts were precisely tuned. Among the screened metals, the addition of Sn yielded the most significant improvement in catalytic activity. The optimized PtSn0.5/C-140 catalyst achieved superior furfural (FAL) conversion and furfuryl alcohol (FOL) selectivity under mild conditions (20 °C, 2 MPa H2). Comprehensive characterizations, including XRD, HRTEM, XPS, and H2-TPD, confirmed the formation of Pt-Sn solid-solution phase. Furthermore, Characterization and reaction results revealed that the electronic and geometric effects induced by Sn modulated Pt active sites, significantly enhancing the adsorption of the active H species. Additionally, the SnOxspecies adjacent to the Pt-Sn sites served as hydrogen spillover acceptors, further accelerating the hydrogenation process. The synergy between the Pt-Sn solid-solution phase and SnOxspecies is identified as the origin of the superior performance at room temperature. These findings provide a new strategy for the design of high-performance biomass conversion catalysts by upgrading commercial noble metal catalysts.

Furfural is a pivotal intermediate in the biomass conversion. Therefore, the production of furfural from xylose or xylose-rich biomass has received extensive attention. Herein, a series of boron phosphate solid acid catalysts (BPs) were synthesized by self-assembly and high-temperature calcination, and used for the production of furfural from xylose or xylose-rich biomass. The results showed that the synthesized BPs was spherical nanoparticles and containing both Lewis acid and Brønsted acid sites, which was excellent for xylose conversion to furfural. The maximum furfural yield of this work was 82.8 % and achieved through 95.7 % xylose conversion by using 20 mg BP 1.25 at a reaction temperature of 130 °C for 120 min with a LiBr⋅3H 2 O/dichloromethane (DCM) biphasic system. Noteworthy, the recycling experiments indicated that both the BP 1.25 catalyst and the LiBr⋅3H 2 O can be reused at least four times with a furfural yield remaining ≥61.7 %. Last but not least, the prepared BP 1.25 catalyst also displayed high efficiency for xylose-rich natural biomass such as corncob and bagasse conversion into furfural. The work not only developed a new system for easy conversion of xylose into furfural, but also realized the high yield production of furfural from natural biomass without components separation.
