Background The conversion of 5-Hydroxymethylfurfural into high value-added 2,5-furandicarboxylic acid is of great significance for industrial production and people's life. Rationally regulation of oxygen vacancy and reactant adsorption are keys to developing an efficient metal oxide catalyst for aerobic oxidation of 5-hydroxymethylfurfural to 2,5-furandicarboxylic acid. Method In this research, nitrogen-doped porous carbon-supported Bi-doped CeO 2 (x%Bi-CeO 2 /N-PC T ) catalysts were successfully prepared by co-calcination method. Significant findings Oxygen vacancy concentration of CeO 2 can be effectively enlarged by Bi-doping, which was strongly related to the catalytic performance. In-situ FTIR and adsorption experiment results showed that the introduction of N-PC T can enhance the HMF adsorption performance of catalyst. Density functional theory calculation and XPS results proved that the HMF adsorption performance depend on content of graphitic N in N-PC T , thus effecting the catalytic performance of HMF oxidation. Synergistic effect of oxygen vacancy and HMF adsorption ability can enhance the catalytic performance, the FDCA yield of 10%Bi-CeO 2 /N-PC 800 was about 70 times higher than that of pure CeO 2 . 10%Bi-CeO 2 /N-PC 800 as support for Au nanoparticles demonstrated an excellent yield of FDCA (92.8%). This study provides a novel idea for design of CeO 2 -based catalyst for oxidation of HMF to high value-added downstream chemicals.

Designing low-cost, high-performance electrocatalysts for the electrocatalytic oxidation of 5-hydroxymethylfurfural (HMF) to produce 2,5-furandicarboxylic acid (FDCA) remains a significant challenge. Herein, we report a novel post-pyrolysis phosphidation method for preparing Nb- and Fe-doped CoP-based catalysts. Nb-CoP@NC delivers a current density of 91.79 mA cm⁻² at a potential of only 1.50 V vs. RHE, achieving nearly 100 % HMF conversion, 98.3 % FDCA selectivity, and 95.6 % Faradaic efficiency (FE). Structural and surface analyses via XRD and XPS reveal that Nb doping significantly modulates the electronic structure of CoP, generating Nb 5+δ active species, which show superior catalytic activity for HMFOR compared to Fe 3+δ . This work not only highlights the pivotal role of Nb doping in enhancing catalytic performance but also provides a general and facile strategy for constructing efficient bimetallic CoP-based catalysts for biomass-derived HMF oxidation.

Nine metal-doped titanium dioxide (TiO2) catalysts (Ti, V, Cr, Zr, Nb, Mo, Hf, Ta, W) were synthesized via a gel precipitation method, and their catalytic performance for the dehydration of glucose to 5-hydroxymethylfurfural (5-HMF) in a biphasic system was systematically investigated. Using characterization techniques such as XRD, BET, NH3-TPD, TGA, and XPS, the regulatory mechanisms of metal doping on the crystal structure, surface acidity, and oxygen species distribution of TiO2 were elucidated. Experimental results demonstrated that niobium-doped TiO2 (Nb-TiO2) exhibited the highest 5-HMF yield (25.1 %), attributed to the synergistic exposure of {101}, {210}, and {201} crystal facets, an optimized ratio of Lewis to Brønsted acid sites, and a high concentration of active oxygen species. Furthermore, by comparing the catalytic performance of different metal-doped systems, it was confirmed that the synergistic effect between the electronic structure of the metal and the lattice oxygen activity of TiO2 was the key factor in enhancing catalytic efficiency.

Aiming to address the key challenges of poor enzyme stability, difficult recovery, and difficult synergistic optimization of catalytic efficiency in high-value conversion of biomass, this study utilizes mineralization self-assembly technology to combine laccase with Fe3O4@SiO2-PMIDA-Cu2+composite, constructing magnetic laccase nanoflower (MLac-NFs) materials with a porous structure and superparamagnetism. This synthetic material can efficiently catalyze the selective oxidation of 5-hydroxymethylfurfural (HMF) to 2,5-furandicarboxylic acid (FDCA). The characterization results indicated that MLac-NFs exhibit optimal catalytic activity (63.4 U mg−1) under conditions of pH 6.0 and 40 °C, with significantly enhanced storage stability (retaining 94.26% of activity after 30 days of storage at 4 °C). Apparent kinetic analysis reveals that the substrate affinity and maximum reaction rate of MLac-NFs were increased by 38.3% and 439.6%, respectively. In the laccase–mediator system (LMS), MLac-NFs mediated by 30 mM TEMPO could achieve complete conversion of HMF to FDCA within 24 h. Moreover, due to the introduction of magnetic nanoparticles, the MLac-NFs could be recovered and reused via an external magnetic field, maintaining 53.26% of the initial FDCA yield after six cycles.

The efficient transformation of glucose into 5-hydroxymethylfurfural (5-HMF) is crucial for sustainable bio-refinery processes, but achieving high production efficiency remains challenging. In this study, we presented the preparation of Al-containing metal-organic frameworks (MOFs), specifically MIL-53(Al), MIL-53(Al)-NO2, and MIL-53(Al)-NH2, using different ligands as catalysts to enhance the production of 5-HMF from glucose. Comprehensive characterization provided valuable insights into the properties of the synthesized MOFs. The synthesized MOFs exhibited varied MIL-53(Al) states, morphologies, and thermal stabilities based on the different ligands employed, which in turn affected their catalytic performance. Among the Al-containing MOFs synthesized, MIL-53(Al)-NH2 demonstrated remarkable catalytic capabilities for the conversion of glucose to 5-HMF. This MOF achieved an impressive 5-HMF yield of 53% and a reaction selectivity of 54%. The catalytic efficiency was further enhanced by leveraging the synergistic effect of MIL-53(Al)-NH2 in combination with Amberlyst-36, resulting in a 5-HMF yield of 59% and a reaction selectivity of 60%.

Graphical Magnetic attraction: We have demonstrated an efficient and environmentally benign magnetic catalyst for the aerobic oxidation of 5-hydroxymethylfurfural (HMF) to 2,5-diformylfuran (DFF). A high DFF yield of 89.1 % and an HMF conversion of 100 % were obtained after 4 h at 90 °C. Magnetic γ-Fe 2 O 3 nanocrystallites encapsulated by hydroxyapatite (HAP), HAP @ γ-Fe 2 O 3 , were prepared followed by cation exchange of Ca 2+ on the external HAP surface with Ru 3+ to give the γ-Fe 2 O 3 @ HAP-Ru catalyst. The structure of the as-prepared catalyst was characterized, and its catalytic activity was studied in the aerobic oxidation of 5-hydroxymethylfurfural (HMF). γ-Fe 2 O 3 @ HAP-Ru showed a high catalytic activity for the aerobic oxidation of HMF into 2,5-diformylfuran (DFF). A high DFF yield of 89.1 % with an HMF conversion of 100 % was obtained after 4 h at 90 °C. Importantly, the synthesis of DFF from fructose was realized by two consecutive steps. The dehydration of fructose in the presence of a magnetic acid catalyst (Fe 3 O 4 @SiO 2 SO 3 H) produced HMF in a yield of 90.1 %. Then the Fe 3 O 4 @SiO 2 SO 3 H catalyst was removed from the reaction solution with a permanent magnet, and HMF in the resulting solution was further oxidized to DFF with a yield of 79.1 % based on fructose. The synthesis of DFF from fructose by two steps avoids the tedious separation of the intermediate HMF, which saves time and energy.

A series of Brønsted acidic ionic liquids (BAILs) functionalized hollow organosilica nanospheres ([C 3/4 Im][OTs/OTf]-Si( Et )Si, C 3/4 = Pr / Bu SO 3 H) were synthesized by two steps. The process involved the preparation of hollow nanosphere supports via a toluene-swollen sol-gel co-condensation of 1,2-bis(trimethoxysilyl)ethane and 3-chloropropyltriethoxysilane in the presence of F127, and followed by a successive quaternary ammonization and protonation with imidazole , 1,3-propane/1,4-butane sultone and trifluoromethane sulfonic acid/ p -toluenesulfonic acid. The adjustable acid property, hollow inner diameter (5–15 nm) and shell thickness (5–9 nm) of [C 3/4 Im][OTs/OTf]-Si( Et )Si are achieved by introducing different organic acids and controlling toluene concentration, respectively. The [C 3/4 Im][OTs/OTf]-Si( Et )Si were applied in selective conversion of fructose to 5-hydroxymethylfurfural (HMF) and 5-ethoxymethylfurfural (EMF) under microwave heating. Under the optimized conditions, the [C 4 Im][OTs]-Si( Et )Si 3.0 nanospheres with the largest inner diameter and the smallest shell thickness exhibit the highest HMF yield (79.4%, 15 min) in fructose dehydration. And the [C 3 Im][OTf]-Si( Et )Si 0.5 nanospheres with the highest acid strength possess the highest EMF yield (70.4%, 30 min) in fructose ethanolysis. The high Brønsted acid-site density and acid strength of [C 3/4 Im][OTs/OTf]-Si( Et )Si catalysts accompanied by high microwave heating energy lead to excellent dehydration/ethanolysis activity. The product selectivity strongly depended on the BAILs structures and morphological characteristics of the catalyst. More importantly, the [C 3/4 Im][OTs/OTf]-Si( Et )Si can be reused three times without changes in leaching of BAILs, due to strong covalent bond between BAILs and silicon/carbon framework. This work will provide a simple strategy of chemically bonded BAILs on suitable supports as efficient solid acids, and an approach of combining morphology-controlled solid acids with microwave-heating for catalytic conversion of biomass/derivatives to fuels and value-added chemicals.

The Cd x In y S ( x +1.5 y ) catalysts with gradient Cd:In ratios were controllably synthesized via an one-step hydrothermal approach. Particularly, the hydrothermal synthesis conferred those Cd x In y S ( x +1.5 y ) catalysts with Cd:In ratios over 1:2 with a one-dimensional–three-dimensional heterojunction structure composed of CdS nanorods and cubic-phase CdIn 2 S 4 . Our characterization evidences reflected that the CdS nanorods effectively promoted the separation of photoexcited electron–hole pairs in Cd x In y S ( x +1.5 y ) and enabled transboundary transfer of photogenerated carriers. Spectroscopic and experimental results were further employed to develop a detailed catalytic mechanism, in which the superoxide anion (•O 2 − ) plays an important role in the catalytic oxidation of HMF to DFF by Cd x In y S ( x +1.5 y ) . Unlike other photocatalysts with •O 2 − as the main active species, Cd 1.5 In 2 S 4.5 gives an excellent performance in HMF conversion. This shows the great potential of cadmium–indium sulfides as photocatalysts for biomass conversion under ambient conditions.

In heterogeneous catalysis research, a significant challenge is to elucidate how metallic copper (Cu0) and cuprous (Cu+) phases interact with their supporting materials, with a special emphasis on how oxygen vacancy (OV) sites participate in hydrogenation processes. In this work, Cu/CexZr10-x catalysts were prepared by introducing Zr-incorporated Ce-MOF, followed by copper impregnation and calcination. Characterization by TEM, XPS, EPR, H2-TPD, Py-IR spectroscopy, and in situ FTIR revealed that Zr doping enhanced the OV concentration, stabilized Cu+ species, and generated abundant Lewis acid sites. The optimal Zr content effectively balances the Cu0/Cu+ redox couples and acid sites, accelerating desired reactions, while excessive Zr incorporation leads to increased Brønsted acidity and promotes undesirable side reactions. These features synergistically enhance the adsorption of 5-HMF, activate carbonyl groups, and facilitate the sequential hydrogenation and deoxygenation processes, thereby achieving 5-HMF fully converted and achieving a 2,5-DMF selectivity of 98.2% under optimal reaction parameters. This study clarifies the cooperative mechanism among Cu active sites, OV, and acid sites in the conversion of 5-HMF and demonstrates that rational Zr incorporation in MOF-derived Cu/CexZr10-x catalysts can precisely modulate surface properties and significantly improve catalytic performance. These findings offer valuable guidance for the rational design of advanced heterogeneous catalysts aimed at biomass valorization and the production of renewable fuel.

Chemically functional microporous metal-organic frameworks (MOFs) crystals are attractive for catalysis applications, and recent results show that they can be immobilized on high stability substrates, such as carbon materials. In this work, g-C 3 N 4 supported UiO-66-type MOFs catalysts with only acid, base or acid-base bi-functional active sites, have been successfully synthesized via a green (aqueous solutions), mild (90 °C, atmospheric pressure), and one-pot modulated hydrothermal (MHT) method. The physical and chemical properties of the obtained catalysts were systematically characterized by different characterization methods. The results indicated that the synthesized catalysts have microporous structure, excellent thermostability and acid-base bi-functional active sites. One-pot synthesis of 5-hydroxymethylfurfural (5-HMF) from glucose was performed to investigate the activities of synthesized catalysts. Benefiting from the synergistic effects of the acid-base bi-functional active sites, the highest 5-HMF yield of 54.9% was achieved in an isopropanol-mediated DMSO system, under the optimal conditions. Moderate to excellent yields of 5-HMF were also obtained from one-pot conversions of other carbohydrates, including inulin , sucrose, cellobiose, maltose and starch , with our developed catalytic system. The one-pot production of 5-HMF from cellulose was also smoothly processed by the g-C 3 N 4 supported UiO-66-type MOFs catalysts in an IL-based system. This work offers a versatile strategy for developing supported UiO-66-type MOFs catalyst for a wide range of biomass transformation to platform chemicals.

5-Hydroxymethylfurfural (HMF) is a high value-added platform compound, converted into bio-based polyesters and biofuels etc. In this paper, we used two commercially available hexamethylenimine and cetyltrimethylammonium bromide (CTAB) as the structure-directing agents to synthesize HMWW zeolite nanosheets via one step. A series of HMWW zeolite nanosheets with different disorder index ( DI ) were controllably prepared by adjusting the amount of CTAB, operating also as an in situ exfoliating agent, converting fructose into HMF in the tetrahydrofuran/NaCl-H 2 O biphasic solvent with low boiling point. Successful construction of disordered HMWW zeolite nanosheets was verified by PXRD. Further characterizations by BET, SEM and TEM etc. show that HMWW 4.0 with the optimum DI of 0.67 has a disordered network-like arrangement of layers with the external surface area of 224 m 2 /g and the mesoporous size of 3.5 nm. Catalytic evaluations showed that HMF selectivity was closely related to DI of the catalysts. Under the optimized DI , fructose molecules are readily accessible to acidic sites on the external surface while larger external surface area is exposed. The HMWW 4.0 zeolite catalyzed fructose dehydration in the biphasic solvent, producing 90% HMF selectivity with 93% fructose conversion at 140 °C for 6 h. In the reuses of the HMWW 4.0 catalyst, HMF selectivity was around 90% with fructose conversion decreasing by ca. 10% after six runs, indicating that it possesses the promising stability.

This study explores the core-shell structure formation mechanisms of primary carbon nanospheres (PCNs) through hydrothermal carbonization (HTC) of glucose at 200 °C, focusing on key phase-change polymerization reactions. Colloidal carbon nanoparticles in the aqueous phase filtrate self-assembled into secondary carbon nanospheres (SCNs) with intrinsic hollow structures during room temperature storage. FTIR results revealed similar functional groups on the surfaces of PCNs and SCNs due to esterification reactions during HTC cooling. XPS and 13 C NMR analyses identified HMF aldol condensation and etherification as dominant reactions for PCNs, while esterification and aldol condensation with levulinic acid were dominant for SCNs. The hypothesis suggests that PCNs initially formed hollow microframeworks but collapsed due to consumption of encapsulated organics, resulting in hydrophobic cores. These cores grew through aggregation (linear) and surface reactions (exponential), internalizing hydrophilic surfaces into hydrophobic cores, forming the final core-shell structure of PCNs.
