The efficient biosynthesis is important for the sustainable development of lignocellulosic ethanol industry, but it is limited by furfural stress produced with cellulose pretreatment. Collagen peptide (CP), as an affluent protein resource, considerably improved the tolerance of Saccharomyces cerevisiae against furfural stress. When the furfural concentration was 2 g/L, the residual sugar concentration was reduced from 122.39 to 8.90 g/L, and the final ethanol yield increased from 30.69 to 87.27 g/L in the presence of CP. In addition, the ethanol yield in CP containing media was higher than those in other peptides. Transcriptome analysis showed CP can improve the expression of genes ( FBA1 , PDC1 , PDC6 , and ENO1 ) associated with glycolysis to promote sugar utilization, and enhance ethanol biosynthesis under furfural stress, which were further verified by quantitative real-time PCR. These results indicated that CP is a promising protectant and accelerator for bioethanol biosynthesis. Graphical abstract

A green and sustainable one-pot paired electrolysis method is introduced for the conversion of furfural (FAL), a biomass-derived platform compound, into gamma-butyrolactone (GBL). A novel approach was developed that integrates the electrochemical oxidation of FAL to furoic acid (FA) at low potential and the subsequent transformation of FA to 2-furanone (2-FO), followed by its reduction to GBL—all within a single, membrane-free cell. By optimizing reaction parameters, over 98.5% selectivity was achieved for the conversion of FAL to FA, and a 60.5% yield of GBL was obtained from FAL. This mild, membrane-free paired electrosynthesis offers an eco-friendly alternative for GBL production and enables the valorization of biomass platform compounds for high-value applications. The potential of renewable biomass to replace petrochemical feedstocks is underscored by the findings presented, aligning with sustainable chemistry principles and supporting a circular economy. This work marks a significant advancement in electrochemical synthesis and renewable chemistry, providing a practical pathway for GBL production from renewable resources.

The hydrogenative rearrangement of biomass-derived furfural offers a sustainable pathway to produce cyclopentanol (CPL) and cyclopentanone (CPO), which are traditionally obtained from fossil resources. Achieving selective synthesis of either product requires precise control over catalyst electronic structure and adsorption behavior, yet it still remains challenging. Herein, we report that both doping and tuning the spatial distance between Pt clusters effectively regulate the d -band center of active sites, enabling selective synthesis of CPO and CPL with high yields of 97.2 % and 96.0 %, respectively. Mechanistic studies suggest that reducing the spatial distance between Pt nanoclusters elevates the d -band center, thereby reducing the occupancy of antibonding states and strengthening the Pt-O bond between Pt and CPO, thus favoring CPL formation. By contrast, doping Pt with NiP lowers the d -band center, thus weakening CPO adsorption and promoting its selective synthesis. These results highlight d -band center regulation as a promising strategy for achieving selective hydrogenation.

The high energy requirements of water electrolysis, driven largely by the sluggish kinetics of the oxygen evolution reaction (OER), hinder its widespread application for hydrogen production. This study presents an innovative alternative by replacing OER with the thermodynamically favorable furfural oxidation reaction (FOR), utilizing a CuPt nanowire (NW)/Cu electrocatalyst. The incorporation of Pt into Cu NWs significantly enhances FOR activity, enabling the production of value-added furoic acid alongside hydrogen gas at reduced voltages. The CuPt NWs/Cu catalyst also exhibits excellent hydrogen evolution reaction (HER) performance in alkaline media. By employing CuPt NWs/Cu as both the anodic and cathodic catalyst, we develop a two-electrode electrolyzer that integrates FOR and HER, allowing simultaneous hydrogen production at both electrodes. Operating at a current density of 10 mA cm −2 , the system requires an exceptionally low cell voltage of 0.39 V and an electricity consumption of 0.47 kWh per m 3 H 2 , demonstrating its efficiency for energy-saving bipolar hydrogen generation.

Electrocatalytic reduction of biomass-derived furan compounds provides a green and sustainable approach to produce value-added fuels and chemicals. Despite the achievements in unimolecular transformation, C–C coupling which holds great promise to yield precursors for high-density fuels has not received extensive attention. Herein, we report a Cu2O-derived nanowire array material with switchable selectivity to electrocatalytic reduction of furfural depending on the electrolyte pH. Besides a high selectivity of 98.4% to furfuryl alcohol via hydrogenation at pH 9.5, the Cu2O-derived array structure also exhibits a high selectivity of 83.5% to hydrofuroin via C–C coupling at pH 14. Upon control experiments and detailed characterization of the electrodes, the array architecture is proposed to decrease the diffusion of ketyl radicals which are the key intermediates for C–C coupling. The confined diffusion results in a high local concentration of the radicals in the array and facilitates their collision for enhancing the formation of hydrofuroin.

Traditional phenol-formaldehyde resin involves the use of petrochemical-based phenol and formaldehyde as feedstocks, raising environmental and health concerns. Herein, renewable biobased substances, i.e., lignin and furfural, were employed to partially replace petroleum-based phenol and formaldehyde for developing greener adhesives by batch copolymerization method. The substitution rates of phenol by acetonitrile-extracted lignin and formaldehyde by furfural can reach 80 and 15%, respectively. The application of these greener raw materials can effectively decrease the emission of toxic content, increasing the viscosity and thermal stability without any sacrifice in the binding performance. The resin with 40% phenol substitution rate and 15% formaldehyde substitution rate displayed superior trade-off between bonding strength (a wet tensile strength of 1.68 MPa) and free formaldehyde content (0.21%) among all biobased resins, much superior to those of commercial adhesive (0.7 MPa and 5%) and those prepared with industrial lignin (0.66 MPa and 0.38%). By using two major biomass-derived feedstocks, this work provides a sustainable strategy to develop a green adhesive featuring superior adhesive properties, enhanced environmental compatibility, and improved thermal stability that shows a broader application potential in the adhesive field.

Yolk-shell nanoreactors feature numbers of advantages in promoting catalytic performance. This work demonstrates the fabrication of yolk-shell Fe 3 O 4 @SiO 2 /Al 2 O 3 - T ( T = 500–900 °C) from metal-organic framework. Characterizations indicate the Fe 3 O 4 yolk and SiO 2 /Al 2 O 3 shell of the obtained nanoreactors. Fe 3 O 4 @SiO 2 /Al 2 O 3 –800 showed excellent performance in furfural acetalization to 2-(dimethoxymethyl)furan, achieving a 97% yield at 60 °C, atmospheric pressure within 5 h. Control experiments reveal the high reactivity of Fe 3 O 4 yolks for furfural acetalization, and acidic Al species are favorable for reactivity promotion. Besides, porous SiO 2 /Al 2 O 3 shells facilitate mass transfer and increase the accessibility of active sites, also contribute to the high performance and stability.

The direct conversion of furfural (FA) from biomass to pentanediols (PeDs), including 1,2-PeD and 1,5-PeD, is important for replacing fossil resources and developing bio-based polyesters from renewable sources. However, achieving high selectivity for the C–O hydrogenation of the furan ring remains a significant challenge. In this study, we synthesized a series of trimetallic CuCoLa catalysts, using a coprecipitation method with various metal ratios. The reduced CuCoLa catalyst with a metal ratio of 1/3/1, exhibited the highest activity for the selective hydrogenolysis of FA to PeDs. Under optimal reaction conditions (160 °C, 4 MPa H 2 for 9 h), CuCoLa(1/3/1)-R achieved yields of 21.7% for 1,2-PeD and 50.1% for 1,5-PeD. Furthermore, the catalyst remained stable after five cycles of FA conversion to PeDs. The high selectivity for PeDs is attributed to the synergistic interaction between Cu and Co and the appropriate number of basic surface sites. Graphical Abstract

The objective of this work is to study the adsorptive separation of the biomass-derived furfural (Fur) and 5-hydroxymethylfurfural (5-HMF). Because Fur and 5-HMF have similar ellipsoidal shapes, the diffusion of the larger 5-HMF may be blocked by the elliptical window of adsorbents. Thus, two zeolitic imidazolate framework (ZIF) materials with the identical chemical composition, MAF-6 and MAF-5, were used as spherical and ellipsoidal pore adsorbents, respectively. In the dynamic column adsorption of a binary-component system (Fur/5-HMF, 5/5 wt %) in an aqueous solution, the adsorption amounts of Fur on MAF-6 display a 13% decrease compared with the single-component system, whereas the adsorption amounts of Fur on MAF-5 are identical to those obtained in the single-component system and the amounts of adsorbed 5-HMF are almost negligible. Thus, the Fur/5-HMF selectivity is only 6.4 for MAF-6, whereas the selectivity reached 115.8 for MAF-5. The results show that the narrow elliptical window/ellipsoidal tile of MAF-5 enhanced separation selectivity compared with the larger circular window/spherical cage of MAF-6. In addition, the general rate model and density functional theory calculations further verify that the elliptical window of MAF-5 exhibits a strong mass-transfer barrier that must be overcome for the diffusion of the larger 5-HMF molecules.

The development of renewable polymers as alternatives to the petroleum-based ones has received significant attention due to the increasing depletion of fossil oil and the associated environmental concerns. In this study, a semi-biomass-based polyimide (PI) film was successfully synthesized, using biomass-derived furfural (HMFA) as one of the raw materials. A two-step approach was first developed for this process: (1) conversion of HMFA to 3,3,4,4-biphenyltetracarboxylic acid dianhydride (BPDA) and (2) polymerization of BPDA with p-phenylenediamine (PPD) to form a PI film. The fabricated PI film demonstrated excellent properties, such as a high thermal decomposition temperature up to 600 °C, a satisfactory glass transition temperature (Tg) exceeding 365 °C, a coefficient of thermal expansion (CTE) of ≈30 ppm/K, a tensile strength greater than 120 MPa, a dielectric constant value below 3.4, a dielectric loss value of less than 0.02, and a 24 h water absorption rate below 0.8%. These performances are comparable to the petrochemical-based PI. This work offers a promising strategy for utilizing biomass-derived materials in polyimide synthesis and would drive a new wave of advancements in polymer science.Keywords:furfural;BPDA;polyimide;biomass;renewable polymer

In this work, the role of Brønsted acid for furfural production in biomass pyrolysis on supported sulfates catalysts was investigated. The introduction of Brønsted acid was shown to improve the degradation of polysaccharides to intermediates for furfural, which did not work well when only Lewis acids were used in the process. Experimental results showed that CuSO 4 /HZSM-5 catalyst exhibited the best performance for furfural (28% yield), which was much higher than individual HZSM-5 (5%) and CuSO 4 (6%). The optimum reaction conditions called for the mass ratio of CuSO 4 /HZSM-5 to be 0.4 and the catalyst/biomass mass ratio to be 0.5. The recycled catalyst exhibited low productivity (9%). Analysis of the catalysts by Py-IR revealed that the CuSO 4 /HZSM-5 owned a stronger Brønsted acid intensity than HZSM-5 or the recycled CuSO 4 /HZSM-5. Therefore, the existence of Brønsted acid is necessary to achieve a more productive degradation of biomass for furfural.

Graphical Rane drops keep fallin’ : Cobalt proved to be the most efficient metal for furfurylamine synthesis by reductive amination of furfural with NH 3 and H 2 . Effect of metal nature on reductive amination was investigated with biomass-based furfural as a typical substrate. Among the tested heterogeneous metal catalysts, cobalt proved to be the most effective metal for the synthesis of the corresponding primary amine. Under a relatively mild reaction condition, 98.9 % yield of furfurylamine was obtained over Raney Co and it can be reused more than eight times without a significant decrease in the catalytic performance. By extensively studying the catalytic pathways and reaction mechanism, it is found that the selectivity to primary amine and secondary amine was governed by the relative rate of hydrogenolysis and hydrogenation of the Schiff base intermediate. The superiority of Raney Co in furfurylamine synthesis can be ascribed to its high efficiency on hydrogenolysis of the Schiff base intermediate and its low performance in the hydrogenation of the Schiff base, carbonyl group and furan ring. Furthermore, ammonia greatly promoted the catalytic hydrogenolysis of the Schiff base intermediate over Raney Co without clear deactivation of the metal active sites.
