Rational design of promising Cu catalyst requires better understanding of the Cu–support perimeter for reactions such as hydrogenation rearrangement of furfural─a pivotal and alternative transformation to produce cyclopentanol. Herein, a series of Cu catalysts with constructed Cu-M-Ox interfaces (M = Zn or Al) have been synthesized. In freshly reduced Cu/ZnO-Alx samples, aluminum species was enriched surrounding Cu. The Cu-Al-Ox contacting interface was formed, and the CuAl2O4 spinal structure was detected as a combining consequence only if Zn and Al species coexisted. The specific metal–support synergistic interaction and Cu-Al-Ox contacting interface simultaneously aroused the enhanced redox property and large number of surface acid sites, facilitating the adsorption/activation of hydrogen and reactants. During the reaction, Al2O3 retreating from the Cu-Al-Ox interface caused the replacement of Cu-Al-Ox by new Cu-Zn-Ox interface, which was directly correlated with the irreversibly changed chemical structure and decreased cyclopentanol yield, although the furfural conversion was well sustained. In this work, we confirmed that supported copper catalysts were competent for the activation and conversion of furfural, with the turnover frequency reaching 28.1 h–1 by the Cu/ZnO-Al3 sample at temperatures as low as 90 °C. The further transformation of cyclopentanone to cyclopentanol was largely depending on the maintenance of a steady Cu-Al-Ox contacting interface.

Furfural is an alternative feedstock and has been used for the production of maleic acid (MA) and fumaric acid (FA) by an oxidation process. Deep eutectic solvents (DESs) were used as the green solvents while sodium chlorate was used as an oxidant and vanadium pentoxide was used as the catalyst at 70–90 °C under atmospheric pressure. It was found that several acidic DESs are valid, such as acetic acid/choline chloride (AA/ChCl) and propionic acid/choline chloride (PA/ChCl), and AA/ChCl DES was selected as the solvent for the conversion. The optimal DES is AA/ChCl, and the effect of the amount of oxidant, time, and temperature on the yield of the MA and FA has been systematically studied, and the conversion of furfural can reach 100% while the yield of the MA and FA reached 66.5% under reaction temperature of 80 °C for 12 h, which provides a new green route to synthesis valuable monomers from furfural.

One-pot conversion of furfural to the target product γ-valerolactone (GVL) is a challenging and meaningful part of biomass exploitation. Development of heterogeneous catalysts with both Brønsted and Lewis acid properties has proved to be promising and useful because they offer an efficient way to tandem cascade reactions from furfural to GVL. Herein, we successfully synthesized sulfated DUT-67(Hf), a novel bifunctional catalyst, via a post-synthetic modification method. The prepared sulfated DUT-67(Hf) was characterized by XRD, SEM, TEM, N 2 adsorption-desorption, Elemental (N, C, H, S) analyses, situ infrared spectra of pyridine adsorptions, XPS, FT-IR, TG, and NH 3 -TPD. The acidity of the catalysts could be adjusted by submersion in different concentrations of aqueous sulfuric acid, giving 0.01 mol/L sulfuric acid for 0.42 mmol/g acidity to 0.1 mol/L sulfuric acid for 2.16 mmol/g acidity. Sulfated DUT-67(Hf) possessed by 0.06 mol/L aqueous sulfuric acid exhibited optimal catalytic activity and showed an 87.1% yield of GVL under the conditions of 180 °C after 24 h of reaction. Moreover, the mechanism of introducing Brønsted acid sites into DUT-67(Hf) and the better hydrogen donors was also investigated through contrasting experiments.

In this paper, the as-prepared metal-organic frameworks material UiO-66 and other Zr-MOFs were directly used as catalytic transfer hydrogenation (CTH) catalysts to catalyze furfural (FF) to furfuryl alcohol (FAL) with 2-propanol (IPA) acted as both solvent and hydrogen donor. The results showed that the as-prepared UiO-66 had satisfactory catalytic activity and selectivity in yielding FAL (97 %) from the CTH of FF at 140 °C within 5 h. Moreover, the as-prepared UiO-66 exhibited relatively stable catalytic activity over five cycles and easy regeneration. Interestingly, UiO-66 was also applicable for the CTH of the other aldehydes such as 5-hydroxymethyfurfural, 5-methylfurfural, 4-methoxybenzaldehyde, and n-hexanal to the corresponding alcohols, affording high product yields up to 98 %. This work provides a green, simple and sustainable process for the catalytic production of FAL from biomass-based furfural, which has certain significance for the sustainable utilization of biomass.

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.

Dual-functional interface isolates ADH and Rh mediator for enhanced stability. • In situ FT-IR captures Rh H formation during electrochemical NADH regeneration. • DFT confirms CoTPP promotes Rh-mediated NADH regeneration. • Integrated cascade enables efficient, selective, and durable furfural reduction. The efficient utilization of biomass resources is a key driver of green and sustainable development. Although electroenzymatic cascade catalysis combines the energy supply of electrocatalysis with the selectivity of enzymatic catalysis, its application is limited by factors such as coenzyme regeneration efficiency, electron mediator stability, and enzyme activity retention. To address these issues, an efficient electroenzymatic catalytic system was constructed for the reduction of furfural to furfuryl alcohol in this work. A hydrophilic polyethyleneimine/dopamine hydrochloride layer was formed on carbon cloth to firmly anchor the rhodium complex mediator (M), thereby reducing the adverse influence of free mediator on enzyme activity. Cobalt porphyrin-modified 3%CoTPP@ZIF-8 was used as the immobilization matrix for alcohol dehydrogenase (ADH), where the confined pore environment improved enzyme stability and promoted substrate enrichment. Structural characterization and electrochemical testing indicate that 3% CoTPP@ZIF-8 exhibits a good balance between charge transfer, active site exposure, and NAD + reduction efficiency. Under −0.8 V (vs. Ag/AgCl), the NADH conversion reached 86% within 2 h. Based on ADH, the calculated TON enzyme and TOF enzyme for furfuryl alcohol production were approximately 21,053 and 3509 h −1 , respectively. The electrode maintained a stable current over 45 h of continuous operation, and the yield of NADH remained around 80% after eight cycles, demonstrating favorable performance in the cascade reaction. In-situ electrochemical FT-IR spectroscopy and DFT calculations revealed that CoTPP optimized the electronic structure, lowered the energy barrier for Rh H intermediate formation and NAD + adsorption, and cooperated with M to accelerate in situ NADH regeneration. Ultimately, coupling this system with immobilized ADH can drive the conversion of furfural to furfuryl alcohol. This provides an experimental foundation for developing systems that couple electrochemical coenzyme regeneration with enzymatic conversion.

Hierarchical Zr-Beta zeolite is realized by the alkali treatment. • Alkali treatment facilitates the conversion of closed Zr sites to open Zr sites. • The open Zr sites are characteristic of Lewis acidity. • Hierarchical Zr-Beta zeolite possess high activity and selectivity in furfural hydrogenation. The catalytic hydrogenation of furfural (FF) into furfuryl alcohol (FAL) is one of the key reactions in the valorization of biomass-derived platform compounds into value-added chemicals and fuels. The present study demonstrates that hierarchically modifying Zr-Beta zeolite (h-Zr-Beta zeolite) via alkali treatment can promote the activity and selectivity in the catalytic transfer hydrogenation (CTH) of FF to FAL, with the FAL formation rate of 8.8 mmol FAL g −1 h −1 . Comprehensive experimental and characterization studies reveal that alkali treatment, not only increases mesoporous within Zr-Beta zeolite, promoting the accessibility of internal active sites within the zeolite, but also increases the proportion of open Zr sites (11.6–54.5%). The consequently enhanced Lewis acidity (4.2 mmol g −1 to 8.8 mmol g −1 ) promotes the selective hydrogenation of FF to FAL. This work provides an efficient strategy for the fabrication of open sites within heteroatom zeolites, which could be of great help for the design of Lewis acid zeolite for Meerwein-Ponndorf-Verley (MPV) reactions in biomass catalysis.

The catalytic conversion of biomass-derived furfural (FAL) to cyclopentanone (CPO) via hydrogenation-rearrangement is a promising route for sustainable fine chemicals. Pt-based catalysts exhibit superior performance but suffer from limited control over hydrogenation behavior and reaction selectivity. To overcome these challenges, we designed a synergistic metal and metal oxide catalyst (1Pt3Ni/MCM-41). Introduction of NiO triggers strong electronic interaction with Pt, tuning both metal active sites and acidic centers. This interfacial electron transfer improves Pt dispersion on the mesoporous MCM-41 support, inhibits aggregation, and stabilizes the catalyst against sintering and leaching. Meanwhile, electron transfer from NiO modulates the electronic structure of Pt, promoting hydrogen dissociation and the formation of active hydrogen species. The charge redistribution also optimizes surface acidity, enhancing selective adsorption and activation of the C=O bond in FAL. Under mild conditions, the catalyst achieves 97.5% FAL conversion, 90.6% CPO selectivity, and a high activity of 883•h -1 . This work provides a rational strategy for designing high-performance bifunctional catalysts for efficient, selective upgrading of FAL to CPO.

High-entropy alloys (HEAs), as new catalytic materials, reveal excellent catalytic performance in numerous reactions. However, how to rationally design high-entropy alloy catalysts with high hydrothermal stability for the efficient hydrogenation of biomass in the presence of water remains a challenge. In this work, we successfully synthesized FeCo3NiCu0.5Zr HEA catalyst by precisely designing the metal composition and adjusting the metal ratio. The catalyst achieved near-complete conversion (>99%) of furfural with up to 98% selectivity toward the target product furfuryl alcohol in the presence of 8% water. Even if the water content increased to 20%, the selectivity of furfuryl alcohol remained above 90% with furfural conversion exceeded 99%. H2-TPR and H2O-TPD characterizations results revealed that the HEA nanoparticles not only possessed excellent hydrothermal stability but also dissociated surface free water molecules to generate H* and *OH. Further, the surface oxygen vacancies are generated through the combination of bridging hydroxyl and terminal hydroxyl groups on the HEA surface, accompanied by releasing of H2O. The carbonyl group of furfural molecule preferentially adsorbs on the surface oxygen vacancy in the catalyst, which effectively shortens the distance between the active hydrogen and the carbonyl group thereby promoting the hydrogenation reaction. This study not only broadens the application of high-entropy metal compounds, but also promotes the directional conversion of biomass to high value-added chemicals in the presence of water.Green foundation1.This work realizes the highly efficient conversion of furfural in the presence of water by delicately designing HEAs. It not only broadens the application range of abundant transition metals in catalysis, but also helps to improve the utilization efficiency of biomass resources and reduce the generation of waste. 2. The designed hydrothermally stable high-entropy catalyst achieved near-complete conversion of furfural with up to 98% selectivity toward the target product furfuryl alcohol in the presence of 8% water. Moreover, the catalyst can maintain high conversion and high selectivity after five consecutive cycles. 3. Future work will focus on finding simpler and more efficient methods to achieve large-scale preparation of high-entropy catalysts for efficient conversion of biomass or biomass platform molecules in the presence of water.

Lightweight and flexible ablative thermal protection materials (TPMs) are critically needed for aerospace vehicles that endure complex dynamic stresses in high-temperature environments. This work presents a lightweight, elastic aluminum silicate fiber/polysiloxane aerogel coated with resorcinol–furfural aerogel (ASF/Si@RFA) composite, fabricated via a facile process involving vacuum impregnation, sol–gel reaction, and atmospheric pressure drying. The composite features a unique multiscale architecture that integrates a macroscopic ceramic ASF felt, a micron-scale flexible and ceramizable SiA, and a nanoporous carbonizable RFA into a highly porous, three-dimensionally interconnected network. This multiscale design yields a low density (∼0.165 g·cm −3 ), superior compressive resilience with full recovery from 60% strain, and excellent thermal insulation (∼34 mW·m −1 ·K −1 ) across both high and cryogenic temperatures, alongside notable hydrophobicity (a water contact angle of 130°). More importantly, exceptional repeatable high-temperature protection performance under a 1300 °C butane flame. A synergistic protective mechanism, arising from the in-situ formation of a silicon oxycarbide barrier, the release of pyrolysis gases for transpiration cooling, the high emissivity of the carbon aerogel, and transverse heat dissipation, results in near-zero surface recession(0.17 μm·s −1 ) and backside temperature below 100 °C throughout 15 heating cycles. This strategy provides a promising pathway for developing advanced lightweight, flexible ablative TPMs.

The electrocatalytic conversion of biomass-derived furfural (FF) into value-added chemicals represents a promising strategy for sustainable chemical synthesis. However, achieving high selectivity toward specific products, particularly C–C coupled dimers for bio-jet fuels, remains challenging due to competing hydrogen evolution and over-hydrogenation reactions. Herein, we developed a non-metallic catalyst derived from lignocellulosic biomass following a facile hydrothermal-pyrolysis process, where the hydrothermally combined heteroatoms by oxygen functionalities are in-situ fixation through high-temperature pyrolysis, together with a hierarchical porous structure that is beneficial for mass transfer. Controlled experiments revealed that pyrolysis temperature proved to be the most critical factor among all synthesis parameters, with 900°C yielding an optimal balance of nitrogen speciation and graphitic framework development that is essential for both activity and selectivity; under optimized conditions, the prepared catalyst (i.e. NC 900 ) achieves 98.7% FF conversion with 50.3% selectivity toward hydrofuroin (HDF) and a Faradaic efficiency of 45.2%. Furthermore, a series of in-situ techniques including the measurement of open circuit potential, hydrogen underpotential deposition, and electron paramagnetic resonance spectroscopy were conducted, which indicated that the electrocatalytic dimerization proceeds through a surface-catalyzed single-electron transfer followed by solution-phase radical coupling. More specifically, FF molecules are first adsorbed and protonated on the nitrogen-doped carbon surface, followed by single-electron reduction to generate carbon-centered radical intermediates, which then rapidly desorb and undergo homocoupling in the solution phase to form the HDF dimer. Nitrogen dopants enhance FF adsorption through electronic modification of the carbon surface, facilitate controlled single-electron transfer at appropriate redox potentials, and promote rapid radical desorption that favors solution-phase coupling over surface-bound side reactions. This work demonstrates the potential of rationally designed metal-free carbon catalysts for selective biomass electroconversion and provides mechanistic insights for developing sustainable C–C coupling strategies. The revealed radical-mediated coupling mechanism lays the foundation for designing mechanism-inspired metallic catalysts with enhanced performance and broadened substrate scope.

Hydrodeoxygenation of furfural (FF) into 2-methylfuran (MF) is a significant biomass utilization route. However, designing efficient and stable non-noble metal catalyst is still a huge challenge. Herein, we reported the N, O co-doped carbon anchored with Co nanoparticles (Co-SFB) synthesized by employing the organic ligands with the target heteroatoms. Raman, electron paramagnetic resonance (EPR), electrochemical impedance spectroscopy (EIS), and X-ray photoelectron spectroscopy (XPS) characterizations showed that the co-doping of N and O heteroatoms in the carbon support endows Co-SFB with enriched lone pair electrons, fast electron transfer ability, and strong metal-support interaction. These electronic properties resulted in strong FF adsorption as well as lower apparent reaction activation energy. At last, the obtained N, O co-doped Co/C catalyst showed excellent catalytic activity (nearly 100 mol% FF conversion and 94.6 mol% MF yield) and stability for in-situ dehydrogenation of FF into MF. This N, O co-doping strategy for the synthesis of highly efficient catalytic materials with controllable electronic state will provide an excellent opportunity to better understand the structure–function relationship.
