2,5-Diformylfuran (DFF) is an important biomass-derived platform chemical, widely recognized as a key intermediate building block in the synthesis of biodegradable polymers and pharmaceutical compounds. The mild and sustainable nature of photocatalysis has attracted considerable attention for such valorization processes, highlighting the need for in-depth exploration of heterostructure-based photocatalysts to enhance catalytic performance. In this study, we report the fabrication and photocatalytic application of a Nb2CTx MXene/ZnIn2S4 (ZIS) Schottky heterojunction with intimate interfacial contact. This heterostructure significantly enhances the separation efficiency of photogenerated charge carriers while prolonging their lifetime. The observed enhancement is attributed to the synergistic interaction between the n-type ZIS semiconductor and the two-dimensional metallic conductor MXene, which induces favorable band bending in ZIS and facilitates the formation of a Schottky barrier at the MXene–ZIS interface. This barrier effectively inhibits electron backflow, thereby promoting charge carrier separation and enhancing interfacial charge dynamics. Compared to pristine ZIS, the Nb2CTx/ZIS heterojunction catalyst achieves a significantly higher DFF yield under ambient temperature and pressure, without the need for additional oxidants. This finding not only demonstrates a highly efficient route for DFF production under mild conditions but also offers a new design strategy for MXene-based Schottky heterojunctions in biomass valorization via photocatalysis.

5-Hydroxymethylfurfural (5-HMF) is a toxic compound formed during the improper processing or storage of honey, endangering human health. Thus, rapid and accurate detection of 5-HMF is essential. In this study, we fabricated uniform gold nanorod (AuNR) array surface-enhanced Raman spectroscopy (SERS) substrates with high-density plasmonic hot spots by optimizing the AuNR aspect ratio and employing a novel three-phase self-assembly technique, significantly enhancing detection sensitivity and reproducibility. The AuNR array (aspect ratio of 3.5) showed the strongest signals due to the close match between its 781 nm longitudinal LSPR wavelength and the 785 nm excitation laser wavelength, enabling efficient resonant coupling. Leveraging the dual-resonance of the AuNR arrays, tip-induced field focusing and nanogap-mediated plasmon coupling synergistically produced ultrahigh electromagnetic enhancement for SERS detection. Using AuNR array-3.5 as the SERS substrate, the signal intensity demonstrated a positive correlation with a concentration of 5-HMF in the range of 1–50 mg/L, with a limit of detection (LOD) as low as 0.093 mg/L. The substrate revealed excellent uniformity (relative standard deviation, RSD = 3.86%), reproducibility (inter-batch RSD = 2.51%), reusability (RSD = 13.2%) and stability (stored at 4 °C for 30 days). In spiked honey samples, this method achieved an LOD of 35.4 mg/kg, well below the international maximum residue limit (40 mg/kg), and recovery values ranging from 73.32% to 95.92%, confirming its high sensitivity and accuracy. This work provided a rapid, efficient approach for detection of 5-HMF in honey and highlights its application potential in SERS-based food safety monitoring technologies.

Mn incorporation into Co 3 O 4 induces Jahn–Teller distortion and Co 3+ spin-state transition ( t 2 g 6 e g 0 → t 2 g 5 e g 1 ). • Such electronic modulation weakens Co O bonding and lowers Co 3+ → Co 4+ kinetic barrier. • Mn-Co 3 O 4 achieves ∼100% HMF conversion, 97.8% FDCA yield, and 96.0% Faradaic efficiency at 1.4 V vs. RHE. • DFT reveals that Mn incorporation reduces the PDS free energy from 4.05 eV to 2.11 eV by facilitating α-C–H cleavage. The electrooxidation of 5-hydroxymethylfurfural (HMF) to 2,5-furandicarboxylic acid (FDCA) is a key transformation for sustainable polymer production, yet its efficiency is hampered by the kinetically demanding cleavage of the α-C–H bonding in the hydroxymethyl group. Herein, we demonstrate that Jahn–Teller distortion serves as an effective strategy to overcome this limitation. By incorporating Mn 3+ ( t 2g 3 e g 1 ) into Co 3 O 4 , we induce a spin-state transition of Co 3+ from low-spin ( t 2g 6 e g 0 ) to intermediate-spin ( t 2g 5 e g 1 ), which weakens Co O bonding and lowers the kinetic barrier for Co 3+ → Co 4+ oxidation. Compared with that of Co 3 O 4 , Mn-Co 3 O 4 achieves a complete HMF conversion with 97.8% of FDCA yield and 96.0% of Faradaic efficiency at 1.4 V vs. RHE, representing a 3.72-fold enhancement in intrinsic activity. Computational and theoretical analysis corroborates that Mn-induced Jahn–Teller electronic modulation not only benefits the adsorption and activation of HMF molecules but also facilitates the cleavage of α-C–H bonding, thereby lowering the reaction barrier. This work establishes Jahn–Teller-distortion-mediated Co 3+ /Co 4+ redox regulation as a focused electronic-structure strategy for promoting high-valence-Co-driven HMF electrooxidation. The Jahn-Teller-driven generation of high-valence Co 4+ species in pristine Co 3 O 4 by the incorporation of Mn 3+ ( t 2g 3 e g 1 ) accelerate the rate-determining initial oxidation of hydroxymethyl groups, markedly enhancing reaction kinetics of HMF to FDCA.

Metal-organic frameworks (MOFs), particularly UiO-66, offer advantages in biomass catalytic conversion due to their good thermal stability, tunable porosity and abundant active sites. However, agglomeration limits their catalytic efficiency. To address this, a series of acid-base bifunctional UiO-66-type catalysts supported on biochar (BC) was developed in green solution through a one-pot method. BC prepared by pyrolyzing cotton stalks (CS) under N 2 atmosphere at high temperature and activated before use. The physico-chemical properties of materials were studied by various characterization methods, and their catalytic performance for converting cellulose to 5-hydroxymethylfurfural (5-HMF) in [BMIM]Cl ionic liquid was evaluated. Reaction parameters such as catalyst type, catalyst loading, temperature and time were optimized. Under the optimized conditions, achieving a 5-HMF yield of 46.58 %. The BC-supported catalyst NH 2 -UiO-66-SO 3 H/BC exhibited significantly higher catalytic activity than its unsupported counterpart and increased the 5-HMF yield by 23.78 %. This performance improvement is attributed to the grafted sulfonic/amino groups, which enhance the catalytic performance by improving the dispersion of UiO-66 upon the introduction of BC. This work demonstrates biochar-supported UiO-66 as an effective strategy for enhancing catalytic efficiency in sustainable biomass valorization to platform chemicals.

The electrocatalytic oxidation of 5-hydroxymethylfurfural (HMF) offers an eco-friendly route to produce 2,5-furandicarboxylic acid (FDCA). Coupling this anodic reaction with the hydrogen evolution reaction provides a sustainable alternative to oxygen evolution reaction in water electrolysis, enhancing energy efficiency while generating green hydrogen. However, conventional nickel-based catalysts suffer from weak substrate adsorption and limited active-site utilization. Here, we introduce a ligand-engineered charge-transfer complex, Ni(TCNQ) 2 (H 2 O) 2 , in which π-conjugated TCNQ ligands enable strong π–π stacking with the furan ring of HMF to enrich substrate adsorption, while the electron-accepting nature of TCNQ mediates metal-ligand charge transfer to regulate the Ni 2+ /Ni 3+ redox couple. This dual function significantly accelerates reaction kinetics and stabilizes intermediates, enabling Ni(TCNQ) 2 (H 2 O) 2 to deliver 100 mA·cm −2 at 1.38 V and nearly 100 % FDCA yield. Mechanistic insights from X-ray photoelectron spectroscopy, operando Raman, and density functional theory (DFT) confirm that ligand-driven adsorption and electron interactions accelerate the catalytic process. DFT free-energy profiles further demonstrate that Ni(TCNQ) 2 (H 2 O) 2 smooths the reaction energy landscape, lowering the thermodynamic barriers compared with Ni(OH)₂. This work underscores the pivotal role of ligand engineering in tuning catalytic interfaces for efficient biomass electrooxidation and green hydrogen co-production in integrated renewable energy systems.

Electrocatalytic 5-hydroxymethylfurfural oxidation (HMFOR) is a sustainable route for biomass valorization to 2,5-furandicarboxylic acid (FDCA), yet balancing the competitive adsorption of HMF and OH− at the electrode−electrolyte interface is pivotal for boosting catalytic activity and selectivity. Herein, we report a terephthalic acid (PTA) modification strategy to tailor Cu-Ni(OH)2 with tunable metal valence and controllable surface charge, fabricating positively charged Cu-Ni(OH)2 and negatively charged Cu-Ni(OH)2-PTA. PTA functionalization elevates the Ni oxidation state and reinforces HMF adsorption on the catalyst surface. In situ surface-enhanced Raman spectroscopy and electrochemical impedance spectroscopy confirm that the negatively charged surface of Cu-Ni(OH)2-PTA efficiently mitigates the steric hindrance of hydrated ions and preserves a fully hydrated Cs+ interfacial microenvironment. This synergy optimizes the adsorption equilibrium of HMF and OH− via efficient and persistent HMF capture, enabling continuous enhancement of HMFOR activity. Consequently, Cu-Ni(OH)2-PTA delivers superior HMFOR performance in CsOH electrolyte, including a high FDCA Faradaic efficiency (98.2%), large current density, excellent cycling stability over 10 cycles, and stable operation for 120 h in a membrane electrode assembly (MEA) system. Notably, a high FDCA Faradaic efficiency of ∼86% is retained even in a pH 13 electrolyte with 1 M Cs+. This work elucidates the coupled effects of metal valence, surface charge, cation hydration, and interfacial water structure on HMFOR, providing a universal interfacial engineering principle for designing advanced electrocatalysts for efficient biomass electrooxidation.

In this paper, water-in-oil (W/O)-type Pickering high-internal phase emulsions (Pickering HIPEs) were stabilized using the modified SBA-15 with appropriate wettability as the stable particle. After thermal polymerization and subsequent sulfonation, we obtained hierarchical porous nitrogen-doped carbon catalysts (SNCs) with acid–base bifunctional active sites. The as-prepared catalysts have hierarchical porous structures, and acidic and basic catalytic activity centers, which can significantly improve the catalytic activity of the conversion of glucose to 5-hydroxymethylfurfural (HMF). The results showed that the highest HMF yield of 61.3% can be obtained, and the recovered catalyst still has a significant catalytic activity after four consecutive cycles. This work offers a versatile strategy for developing nitrogen-doped carbonaceous catalysts for a wide range of biomass transformation to platform chemicals.

The biomass electrochemical oxidation has attracted worldwide attention owning to its carbon-neutral and sustainable nature. Here, different morphologies of CoCu-carbonate hydroxides (CH) electrodes are prepared through one-step hydrothermal method for 5-hydroxymethylfurfural electrocatalytic oxidation (HMF-ECO) to high-valued 2,5-furandicarboxylic acid (FDCA) for the first time. The results illustrate that Cu can regulate CoCu–CH morphologies from 1D nanorods to 2D ultra-thin nanosheets besides modulating the catalytic compositions . The optimal Co 1 Cu 1 –CH exhibits hybrid nanostructures containing the 1D nanorods and 2D ultra-thin nanosheets , which has the largest ECSA and specific surface area, as well as the smallest Tafel slope and impedance. The oxidation potential of HMF-ECO is 1.42 V vs RHE with the conversion of HMF 99.57%, the selectivity for FDCA 99.91%, and the FE 98.88%. In addition, Cu can promote the conversion of Co 2+ to the favorable Co 3+ for HMF-ECO on the catalyst surface . Density functional theory calculation indicates that Cu can improve charges transfer to HMF and lower its adsorption energy . In situ Raman spectra tests indicate that cobalt species is the active site for HMF-ECO. Furthermore, at 1.42 V vs RHE, the coupling of HMF-ECO and hydrogen evolution reaction shows that the cathodic hydrogen evolution rate is 92.33 L h −1 m −2 , which is 3.69 times more than water splitting. This work provides a special structures material to process intensification of HMF electrooxidation coupling hydrogen production .

Hydrothermal treatment of cellulose is a promising green route for bioenergy and biochemical production, yet requiring investigations of the mechanisms. In this study, the effects of cellulose crystallinity and decoupled temperature and pressure conditions on cellulose conversion and product distribution were investigated. Microcrystalline cellulose was ball-milled for varying durations, leading to a reduction in crystallinity, with 4 h of milling sufficient to achieve near-complete amorphization. Unlike concurrent recrystallization and hydrolysis observed under autogenous pressure, decoupled conditions significantly accelerated hydrolysis of cellulose. Notably, lower crystallinity cellulose exhibited significant improvements in glucose and 5-HMF yields, with 4-hour ball milling showing optimal performance among all samples. Furthermore, carbon sub-micron spheres were largely produced, which were confirmed via PTFE encapsulation experiments to primarily consist of secondary char deriving from re-polymerization and condensation reactions of the liquid phase. Overall, this study demonstrates that lower crystallinity not only facilitates hydrolysis but also accelerates the carbonization processes under decoupled pressure conditions, highlighting its potential for efficient biomass conversion into valuable products.

Efficient valorization of cellulose is a sustainable route yet a challenging topic to solve the crisis of fossil resources. Although heterogeneous catalysts such as metal oxides have various advantages, the low surface contact area between metal oxides and cellulose is unfavourable for the hydrolysis of cellulose and thus restricts the application of metal oxides in direct conversion of cellulose to 5-hydroxymethylfurfural (HMF). This work presented the utilization of in-situ carbonic acid from CO 2 as a green acid to enhance the conversion of cellulose to HMF in the presence of ZrO 2 and TiO 2 . Combination of in-situ carbonic acid, ZrO 2 and TiO 2 exhibited a distinctive catalysis on the hydrolysis of cellulose and monosaccharide , isomerization of glucose and monosaccharide conversion in tetrahydrofuran (THF)/H 2 O/NaCl system. Especially, in-situ carbonic acid played a significant role in cellulose degradation and accelerated transforming insoluble polysaccharide into soluble oligosaccharide or monosaccharide, and thus promoted the cellulose conversion catalyzed by metal oxides. A high yield of HMF from cellulose (48.4%) was achieved by physically mixing commercial TiO 2 , ZrO 2 , and CO 2 . Due to the significant effects on cellulose degradation and HMF selectivity improvement, in-situ carbonic acid offers a green, low-cost and environmentally friendly co-catalyst for highly effective converting cellulose into HMF.

The concept of converting biowaste to energy is popular worldwide; however, overcoming the trade-off between bio-oil recovery and obtaining functional biochar remains challenging. This study investigated the effects of three transition metal ions (Mn 2+ , Cu 2+ and Fe 2+ ) throughout the entire process of recovering 5-hydroxymethylfurfural (5-HMF) from forestry waste and on the catalytic abilities of biochar derived from the oil-extracted residue. The Cu 2+ , Fe 2+ , and Mn 2+ ions significantly increased 5-HMF yields by 93- to 158-fold compared to the metal-free control. However, only marginal improvements in the catalytic ability of the residue-derived biochar for persulfate activation were observed for Cu- or Fe-doped biochar, despite the general benefit of transition metal doping for biochar functionalization. Interestingly, a dual Mn-mediated promotion was achieved beyond enhancing 5-HMF production. The Mn-doped biochar (Mn-Biochar) exhibited excellent peroxydisulfate (PDS) activation capability, enhancing the degradation of the antibiotic sulfamethoxazole (SMX) by 6.6- to 15.0-fold. Characterizations revealed that incorporated nitrogen was responsible for this enhancement. N-doping transformed the Mn species into MnO, which tripled the Mn loading capacity and enhanced the electrical conductivity of the biochar. The formed Mn-N x structure in the biochar (Mn-N-FBBC) facilitated polarization of the O O bond and cleavage of the S O bond in PDS, generating 1 O 2 for SMX degradation. Life cycle assessment (LCA) indicated that this dual Mn-mediated process for 5-HMF recovery and biochar production offers synergistic benefits, realizing the “waste-resource-material-treatment” paradigm in biomass conversion.

Metals embedded nitrogen-doped carbon (M/NC) materials have garnered substantial attention due to the catalytic active centers provided by their transition metals. Here, the ZIF-67 derived Co/NC hollow structure catalyst (Co/NHC-4) exhibited remarkable performance in the hydrogenation of biomass-based 5-hydroxymethylfurfural (HMF) to valuable 2,5-dihydroxymethylfuran (DHMF). Under mild conditions of 60 °C and 2 MPa H 2 , the conversion of HMF reached nearly 100 %, with DHMF selectivity >99 %. Through the integration of advanced characterization techniques, such as TEM, XPS, XAFS, Raman spectroscopy, vapor adsorption curve, H 2 -TPD and in situ FTIR spectroscopy, it was demonstrated that the superior hydrogenation performance of hollow-structured catalysts primarily stems from unique morphology. Specifically, the hollow morphology facilitates the adsorption and diffusion of HMF on Co surface, which substantially enhances the hydrogenation efficiency. DFT calculation reveals the preferential parallel adsorption geometry of HMF and the energetically favorable hydrogenation pathway.
