The development of efficient electrocatalysts for biomass-derived furfural hydrogenation is crucial for sustainable chemical production. Herein, we report a systematic study of transition metal catalysts for electrocatalytic furfural reduction to furfuryl alcohol (FA) synthesized by precisely controlled magnetron sputtering. Monometallic thin films (Cu, Ni, Co, Ag, Cr, Mo and W) on Ti substrates reveal a volcano-shaped correlation between the d-band center position and catalytic activity, establishing fundamental binding energy-activity relationships. Building on these insights, we designed bimetallic CuNi alloys with tunable compositions, where the Cu 40 Ni 60 variant demonstrated exceptional performance, achieving twice the FA formation rate of pure Ni while maintaining 100% selectivity. Mechanistic studies reveal that the Cu 40 Ni 60 catalyst exhibits intermediate behavior between Cu (preferring the Langmuir–Hinshelwood pathway) and Ni (favoring the proton-coupled electron transfer pathway), with enhanced contributions from both pathways synergistically boosting the overall reaction rate. Alloying induces synergistic electronic effects that optimize furfural and H adsorption energy to regulate surface coverage and balance the reaction pathways. This work establishes a standardized platform for evaluating composition-activity relationships in furfural hydrogenation and provides fundamental design principles for non-precious metal alloy catalysts, highlighting electronic structure engineering as a key strategy for optimizing hydrogenation performance.

Furfural is a prominent biomass-derived platform compound.
Catalytic
transfer hydrogenation enables the hydrogenation of furfural without
external hydrogen. In this regard, alumina microspheres combining
unsaturated aluminum sites, surface acid–base sites, and hierarchical
pore structure represent potential catalysts for this process. Herein,
hierarchically structured flower-like alumina microspheres (FAMS)
with precisely modulated surface properties were synthesized via a
surfactant-directed strategy. A comparative study of microspheres
synthesized with structurally different surfactants revealed that
flower-like alumina microspheres prepared using the double-hydrophobic
tail surfactant AOT exhibited expanded mesopores, an enriched penta-coordinated
aluminum (Al V ), and superior acidic site density. Meanwhile,
the linear cationic CTAB can generate more basic sites on FAMS. In
the CTH of furfural to furfuryl alcohol, FAMS-AOT achieved a maximum
overall reaction rate and complete furfural conversion to furfuryl
alcohol within 2 h at 150 ° C. Comparisons with other surfactant-derived
FAMS indicate that a higher absolute Al V relative content
drives the macroscopic reaction rate, while the surface basic sites
prompted acid–base synergy to improve TOF. This work provides
a facile and promising pathway for the surface modulation of alumina
microspheres toward the conversion of furfural into furfuryl alcohol.

Sulfur incorporation facilitates in situ oxygen-vacancy formation in TiO 2 . • S–O formation and S–V O coupling regulate the electronic structure of TiO 2 . • Oxygen vacancies promote furfural adsorption and activation. • Sulfur-mediated defect engineering enables selective furfural hydrogenation. • S 0.75 -TiO 2 achieves 44.0 mmol FA ·g cat. −1 ·h −1 with 99.5% FA selectivity. Photocatalytic transfer hydrogenation (PTH) of biomass-derived furfural (FF) to furfuryl alcohol (FA) using methanol as a green hydrogen donor represents a sustainable route for producing value-added chemicals, yet developing robust noble-metal-free catalysts remains challenging. Herein, we present a sulfur-doped TiO 2 photocatalyst exhibiting exceptional activity and selectivity for FF hydrogenation. The optimized catalyst delivers an impressive space-time FA yield of 44.0 mmol FA ·g cat. −1 ·h −1 with 99.5% selectivity under 500 mW·cm −2 irradiation, surpassing most state-of-the-art systems. Comprehensive characterizations and theoretical calculations reveal that lattice-substituted sulfur atoms form surface S–O species, driving oxygen vacancy formation and modulating the electronic structure of TiO 2 . The synergistic interaction between S species and V O sites regulates the electron density at active sites, thereby markedly promoting FF adsorption/activation, charge separation, and targeted hydrogenation. This work establishes a strategy for constructing high-efficiency, non-precious photocatalysts through sulfur-mediated oxygen-vacancy engineering.

Graphical Hydrogenation of furfural to furfuryl alcohol under H 2 and N 2 atmosphere are studied over PdCu/ZrPO with metal and Lewis acid sites. The PdCu metal active sites of PdCu/ZrPO involve both direct hydrogenation and transfer hydrogenation activities, and the Zr 4+ −O 2− Lewis acid-basic pairs of ZrPO have transfer hydrogenation activity. Hydrogenation of furfural to furfuryl alcohol under H 2 and N 2 atmosphere was studied over zirconium phosphonate (ZrPO)-supported PdCu (PdCu/ZrPO) catalysts. The direct hydrogenation and transfer hydrogenation activities of PdCu metal active sites and the transfer hydrogenation activity of Zr 4+ −O 2− Lewis acid-basic sites were investigated, respectively. The size and the distribution of Cu particles could be adjusted by altering the P/Zr molar ratio. Bimetallic PdCu could enhance the acidity of the PdCu/ZrPO catalysts, and improve the ratio of Lewis/Brønsted acid, which led to an increase in the transfer hydrogenation activity of Lewis acid-basic pairs. The electronic effect between Pd and Cu promoted furfural to absorb onto electron-deficient Cu through η1(O)-aldehyde configuration, which contributed to the direct hydrogenation and the transfer hydrogenation at metal active sites. Especially, the adsorption and dissociation of H 2 in electron-rich Pd were promoted, which significantly improved the direct hydrogenation activity.

Preparing porous carbon electrode materials for high-performance supercapacitors using green, low-cost, and well-sourced renewable resources is increasingly becoming an important research area. This paper highlights the possibility of furfural residue (FR) as a precursor to porous carbon for utilization as supercapacitor electrode materials. We propose a simple method to prepare FR-based nitrogen-doped porous carbon through H 3 PO 4 hydrothermal pretreatment and KOH/melamine synergistic activation. The obtained carbon material (NFRPC-700) displays a large specific surface area(3259.4 m 2 g -1 ), high pore volume(1.67 cm 3 g -1 ), and excellent nitrogen doping. In the three-electrode system, NFRPC-700 demonstrates great electrochemical performance (specific capacitance value of 337 F g −1 at 0.5 A g −1 ). Assembly into a symmetric supercapacitor provides superior cycling stability (the capacitance retention remained essentially unchanged after 20,002 cycles at a current density of 5 A g −1 ) and high energy density(11.81 Wh kg −1 at 275 W kg −1 power density). This study provides an effective method to achieve high-value utilization of FR waste.

Experiments were carried out to investigate cellulose and furfural from catalytic hydrolysis of corncob. This process improved the comprehensive utilization of hemicellulose and cellulose in biomass resources. Influence of factors (temperature, reaction time, concentration of catalysts, liquid to solid ratio (LSR)) on hydrothermal characteristics, furfural yield, properties and retention of cellulose were investigated through orthogonal and parameter tests. Acetic acid (6 wt%) and FeCl 3 (40 mM) achieved the highest furfural yield (47.60%) and relatively high cellulose retention ratio (71.84%) at 180 °C, 45 min, and 3 mL/g of LSR. While AlCl 3 and citric acid obtained low furfural yield and the lowest cellulose retention ratio (8.38%). Furfural was dominant in distillated organics (GC-MS areas ≥97.9%), by contrast furfural, 5-hydroxymethyfurfural and vanillin were main organics in residual liquors. The peak of furfural yield switched to shorter reaction time as temperature increased. Combination of AlCl 3 with acetic acid and citric acid accelerated cellulose degradation. NaCl inhibited furfural yield and promoted lignin decomposition. Higher temperature and greater concentration of FeCl 3 contributed to reduced crystallinity of cellulose during hydrothermal treatment.

Exploring low-cost green catalysts to achieve green organic chemicals and fuels from biomass is one of the crucial ways to solve the energy crisis. The 20 wt% Co-CoO x /AC catalysts were prepared to achieve the one-pot conversion of furfural to 2-methylfuran under milder reaction conditions (120 °C, 2.5 MPa H 2 ), shorter reaction time (5 h) and less catalyst dosage by regulating the ratio of metal to oxide species. The yield of 2-methylfuran reached 87.4 % is achieved under 20 wt% Co-CoO x /AC catalyst conditions, and there was no significant degradation of all catalyst properties after five cycles. Characterization results showed that the active components in the catalyst were present as Co 0 species with CoO x species. The reaction mechanism was explained by combining the characterization results, experimental data and DFT calculations. The formyl group of the furfural side chain is first adsorbed on the Co 0 species, and furfuryl alcohol is produced in the presence of the Co 0 species. Subsequently, the CoO x species adsorbs the C O bond on the side chain, which is broken in the presence of the CoO x species to form 2-methylfuran. The excellent catalytic activity of the 20 wt% Co-CoO x /AC catalyst provide a promising application for preparing 2-methylfuran by hydrodeoxygenation of furfural.

Meerwein-Ponndorf-Verley (MPV) reaction has been widely acknowledged to be a mild catalytic transfer hydrogenation method for selective reduction of biomass-derived furfural to furfuryl alcohol . Herein zirconium-containing mesoporous composite catalyst was developed through the combination of sol-gel process and soft templating method, in which naturally abundant glucose and F127 triblock copolymer were used as the ligand and pore-forming agent, respectively. The hydroxyl groups in glucose molecules were demonstrated to be coordinated with zirconium ion during hydrolysis-condensation of zirconium precursor, leading to the even dispersion of zirconia nanoparticles in the composite catalyst. The composite catalyst was proven to be highly efficient for catalyzing MPV reduction of furfural with the maximum furfuryl alcohol yield of 93.4% at 180 °C within 180 min in 2-propanol, which served as both solvent and reductant . The composite also showed a good reusability . After five consecutive reaction cycles, furfuryl alcohol yield was slightly reduced from 93.4% to 77.7%, but it could be recovered to 92.8% after the reused composite was regenerated with dilute alkali solution. Batch experiments and systematic characterizations demonstrated that the excellent catalytic performance of composite catalyst was determined by multiple factors mainly including the stronger Lewis acidity, a considerable amount of basic site and the rich mesoporous structure. This study provides a facile strategy to prepare multifunctional composite catalysts using naturally abundant carbohydrates as the feedstocks for lignocellulosic biorefinery .

Tertiary amines, currently obtained from fossil resources by a multi-step synthetic method, are important compounds in both chemical industry and organic transformations. Herein, we demonstrated highly efficient and convenient strategy to various biomass-based tertiary amines in excellent yields (85–95%) by a direct and consecutive reductive amination of furfural with various amines in one-pot using rhodium phosphide (Rh 2 P) catalyst. Typically, biomass-based tris (2-furanylmethyl)amine in 92% yield was directly obtained from furfural and HCOONH 4 in one-step. Time-dependent reaction profiles suggested a consecutive amination/hydrogenation pathway with furfurylamine-derived Schiff base and secondary amine as successively detected intermediates. The superiority of Rh 2 P was ascribed to its excellent low-temperature hydrogenation activity, which is structurally attributed to an efficient electron-transfer from P atoms (on the P-terminated Rh 2 P) to their bonded and dissociated H atoms. This research thus highlights a powerful, elegant, and attractive approach to biomass-based tertiary amines for a sustainable extension of amine chemistry.

Functionalized monomers are of utmost importance in producing new polymers and smart materials. Herein, a two-step approach involving heterogeneous catalysis was developed to produce a functionalized monomer (2-vinylfuran) from bio-based furfural, giving an overall yield of 89%. Economic analysis suggests that this facile approach incurs much lower costs, and its practicality improves the availability of 2-vinylfuran. This is due to the delicate structure of the optimized 4Na5Ce/SiO2, where Na species are present at the oxygen vacancies of the ceria that protect the catalyst structure from collapse, and the catalyst consequently displays excellent performance. Density functional theory (DFT) calculations revealed that the reaction occurs on the Na and Ce species. The adsorption of a furan group onto Na led to side reactions, which were suppressed in the presence of Ce, resulting in higher selectivity. Finally, a polymer based on 2-vinylfuran was prepared, which shows good surface properties and thermodynamic stability.

The alkali-soluble hemicelluloses extracted with 10% KOH solution from corn bran were further isolated with different concentrations of aqueous ethanol solutions. Herein 92.2% of the original hemicelluloses can be obtained and the cellulase enzymatic hydrolysis rate of the alkali treated corn bran can reach to 97.2%. The corn bran hemicelluloses were mainly glucuronoarabinoxylan , in which xylose (48.4–53.8%) and arabinose (27.8–33.2%) were the main components. More linear hemicelluloses with high molecular weight tended to be precipitated in low concentration aqueous ethanol solutions. Furthermore, the relationship between the structural features of these alkali-soluble corn bran hemicelluloses and their furfural yield was investigated in MIBK (methyl isobutyl ketone)/H 2 O biphasic system. Results showed that the hemicelluloses with high xylose content are benefit to the furfural production, and the highest furfural yield of 67.7% was obtained.

A bifunctional Ni 3 P/γ-Al 2 O 3 catalyst with both metal site and Lewis acid site was prepared by an electroless plating method, and applied in hydrogenative ring-rearrangement of furfural to cyclopentanone. The obtained catalyst was characterized by XRD, XPS, XAS, N 2 adsorption-desorption, ICP, TEM, CO chemisorption, NH 3 -TPD and Py-FTIR. The ultrafine Ni 3 P nanoparticles (∼3.8 nm) were highly dispersed in the catalyst. The exclusive Lewis acidity of Ni 3 P/γ-Al 2 O 3 was beneficial for the aqueous-phase hydrogenative ring-rearrangement. The effects of DP time, reaction parameters (temperature, H 2 pressure, solvent composition, and reaction time) on the catalytic performance were investigated. The yield of cyclopentanone was 74.6% at furfural conversion of 99.9% at 180 °C in 1 h over Ni 3 P/γ-Al 2 O 3 catalyst using pure water as the solvent. Moreover, the kinetics of hydrogenative ring-rearrangement of furfural catalyzed by Ni 3 P/γ-Al 2 O 3 was investigated.
