The electrochemical oxidation of HMF (HMFOR) to FDCA presents a promising alternative to the anodic oxygen evolution reaction (OER) in water electrolysis, offering reduced energy consumption and enhanced safety. However, achieving efficient FDCA production is hindered by the instability of HMF in alkaline media and the critical challenge of generating and stabilizing the high-valence metal active centers required for oxidizing the less reactive alcohol group in HMF at practical rates and potentials. This study addresses this challenge by constructing a Co(OH)2/Cu(OH)2 heterostructure on copper foam (CF) via a facile two-step synthesis. Comprehensive characterization, including in situ Raman spectroscopy, reveals significant electron transfer from Co to Cu within the heterostructure. This electronic interaction elevates the oxidation state of Co, thereby facilitating the generation of high-valence CoO2 and enhancing its stability compared to that of pure Co(OH)2. Consequently, the Co(OH)2/Cu(OH)2/CF electrode exhibits a high current density of 200 mA·cm–2 at 1.4 V vs RHE in 20 mmol/L (mM) HMF, along with nearly 100% carbon balance within 60 min. Mechanistic studies confirm that the stabilized CoO2 centers promote strong adsorption of HMF, particularly activating the alcohol group for efficient oxidation to FDCA. This work provides a viable electronic structure modulation strategy for stabilizing high-valent metal centers through interfacial electronic modulation toward efficient biomass electrooxidation.

Sunlight-driven conversion of biomass into value-added chemicals is crucial for building a sustainable energy future. However, this process often suffers from inefficient light utilization and unclear regulation of reactive oxygen species in photocatalysis. An Fe-doped graphitic carbon nitride (CNFe) photocatalyst was synthesized via a thermal polymerization method and 71.53% conversion of 5-hydroxymethylfurfural (HMF) with 55.56% selectivity to 2,5-furandicarboxylic acid (FDCA) were achieved under visible light. The catalyst was reused for at least four consecutive cycles without significant activity loss, demonstrating good recyclability and stability. Fe doping created a porous sheet-like structure with uniformly embedded Fe 3 O 4 nanocrystals and active Fe-N x sites, which enhanced visible-light absorption and charge separation. The Fe 3 O 4 /g‑C 3 N 4 Z‑scheme heterojunction, synergizing with the redox‑active Fe 3+ /Fe 2+ sites, facilitates efficient O 2 activation to generate selectively superoxide radicals (•O 2 - ). This work demonstrates a feasible strategy for designing efficient non-noble-metal photocatalysts and provides deeper insight into ROS regulation for the sustainable upgrading of biomass-derived feedstocks.

The function to induce dynamic-phase shifts between mono/biphasic systems is crucial to separation processes. Switchable (pH driven) ATPS composed of DESs and salts are here disclosed to act as integrated platforms for the production-separation processes. The catalytic carbohydrate conversion to 5-hydroxymethylfurfural (5HMF) was conducted in a homogeneous acidic aqueous-DES medium. Then, the formation of the biphasic region was induced by tailoring the pH of the aqueous homogeneous medium, leading to the complete separation of 5-HMF from the carbohydrate. Herein, the effects of the phase-forming DES species (composed of ethanol/n-propanol and [N 4444 ]Cl), the K 3 C 6 H 5 O 7 concentration and pH on the distribution of 5-HMF and fructose in DES-ATPSs were investigated. The optimal composition of the DES-ATPS system was 30 wt% [N 4444 ]Cl:ethanol (1:2) or [N 4444 ]Cl:n-propanol (1:2) and 35 and 40 wt% K 3 C 6 H 5 O 7 , respectively. The results showed that the integrated platforms have good catalytic effect, and the conversion rate of fructose reached 87.21%, with a 5-HMF yield of 46.76% and 0.1 g of apple peel produced 15.43 mg 5-HMF. The extraction efficiency of the DES-ATPS composed of [N 4444 ]Cl:ethanol (1:2) and [N 4444 ]Cl:n-propanol (1:2) were the highest within 20 min (5-HMF extraction efficiency 98.53% and 98.59%, respectively), which has economic benefits and comprehensiveness.

BACKGROUND The conversion of glucose into 5-hydroxymethylfurfural (5-HMF) involves the isomerization of glucose to fructose catalyzed by Lewis acid and subsequent dehydration of fructose catalyzed by Brönsted acid. In this work, in order to obtain a high yield of 5-HMF, a series of Sn-Al-Beta catalysts containing both Lewis and Brönsted acid sites were prepared by a convenient solid state ion exchange (SSIE) method using partially dealuminated Beta zeolite and tin(II) acetate. RESULTS The obtained bifunctional catalysts were investigated for one-pot production of 5-HMF from glucose in the ionic liquid (IL) [C 4 mim]Cl. Among various catalysts, Sn-Al-Beta- 4 - 8 exhibited the best catalytic performance, giving a 5-HMF yield of 54% under optimal reaction conditions (393 K, 2 h), along with a glucose conversion of 81%. The Sn-Al-Beta- 4-8 catalyst and IL were regenerated by the extraction of 5-HMF, and the reactivity was reserved after five runs of recycling. In addition to glucose, the Sn-Al-Beta- 4-8 /[C 4 mim]Cl system was also proven to have the potential to effectively convert other carbohydrates into 5-HMF. CONCLUSION The results suggested that the catalyst is convenient to prepare and has preferable efficiency and stability in the conversion of carbohydrates into 5-HMF. © 2022 Society of Chemical Industry (SCI).

Rational design of highly efficient non-noble-metal catalysts for the selective hydrogenolysis of biomass platform compounds to produce fuels and fine chemicals is a key pursuit for the sustainable chemical industry. In this work, we report for the first time the synthesis of a Ni-supported germanosilicate zeolite (Ni-SCM-14) catalyst by a simple grinding method, showing both satisfactory yield (90.3%) and good stability in eight cycles for the hydrogenolysis of 5-hydroxymethylfurfural (HMF) to 2,5-dimethylfuran (DMF). Characterization revealed that Ni nanoparticles were highly dispersed on the SCM-14 zeolite with strong interactions. The synergistic effect of highly dispersed Ni hydrogenation sites and the weak acidity activation of the C–O bond provided by SCM-14 is considered to be the key to the efficient hydrogenolysis of HMF. This discovery opens up a new avenue for germanosilicate zeolite to activate the C–O bond.

Converting carbohydrates to 5-hydroxymethylfurfural (HMF) is an important goal for biorefinery. Although various deep eutectic solvents (DESs) have been reported for HMF production, the field lacks systematic research on the effect of cations and anions and an effective catalytic system for converting concentrated carbohydrates. Here, 12 kinds of DESs containing four cations and six anions were systematically evaluated and tetraethylammonium bromide (TEAB) was confirmed as the most effective DES, which provided HMF yields of 90 and 76% from fructose and glucose, respectively. The stable bromide-substituted intermediate may explain the positive effect of bromide based on the results of density functional theory calculation. A high concentration substrate has an adverse impact on the selectivity of HMF due to the HMF concentration caused by glucose, CrCl3·6H2O, and concentrated HMF. To inhibit the condensation, a biphasic system of TEAB/THF is developed to convert a highly concentrated glucose of 62.5 wt % (83.3 wt % with respect to TEAB), providing an excellent HMF yield of 72%. This study has revealed the impact of cations and anions of DESs on HMF production, which will serve as a base for designing task-specific DESs. Moreover, an efficient catalytic system to produce HMF from concentrated glucose was also provided.

Furfural derivatives like 5-hydroxymethylfurfural (HMF) are potent fermentation inhibitors whose selective removal remains a bottleneck in biorefining due to limited pore-level mechanistic understanding. Here, we deploy five metal-organic frameworks with graded pore apertures to elucidate pore-size effects on HMF adsorption. Integrated kinetic, thermodynamic, and dynamic breakthrough studies reveal a volcano-type trend governed by a dual trade-off between steric accessibility and spatial confinement. MIL-53(Al)-TDC, with an optimally matched 8.1 Å pore balancing rapid intracrystalline diffusion with strong host-guest affinity, synergizes π-π stacking and hydrophobic microenvironments to deliver an HMF capacity of 579.58 mg·g-1 and mass transfer coefficient of 22.36 L·g-1·h-1. Breakthrough experiments demonstrate its potential for continuous purification of simulated hydrolysate. A technoeconomic assessment confirms 33-50% lower equipment investment and 47-51% lower annualized cost vs conventional distillation. This work establishes a predictive framework coupling pore commensurability with interfacial interactions, guiding rational design of adsorbents for biorefinery separations.

Simultaneous production of value-added 2,5-furandicarboxylic acid (FDCA) and H 2 from the integrated 5-hydroxymethylfurfural (HMF) oxidation and hydrogen evolution reaction by electrocatalysis has drawn tremendous attention due to the significantly improved energy efficiency. However, HMF is not thermally and chemically stable enough to often cause heavy degradation, impeding its storage and industrialization. In this work, a more stable furan molecule, 2,5-bis(hydroxymethyl)furan (BHMF), was employed as the reaction substrate into the coupling system for the first time. By means of facile electrodeposition and subsequent oxidative activation, the standing CoOOH nanosheet electrocatalyst was fabricated to realize a complete BHMF conversion with 90.2 % FDCA yield and 100 % current efficiency for H 2 evolution. The reaction path and apparent activation energies were therefore discussed. Scalable properties and electrochemical durability of CoOOH were evaluated in a continuous flow reactor to harvest gram-level solid FDCA, highlighting the prospect of green coupling electrolysis for industrial application.

Electrocatalytic 5-hydroxymethylfurfural oxidation reaction (HMFOR) enables sustainable high-value chemical production and carbon neutrality, but its kinetics are impeded by sluggish dehydrogenation arising from multi-step proton-coupled electron transfers (PCET). Herein, a built-in electric field (BEF) is rationally engineered via a CuCo 2 O 4 /CeO 2 heterostructure. The BEF drives interfacial charge redistribution to optimize Lewis acid sites and enrich oxygen vacancies. Consequently, CuCo 2 O 4 /CeO 2 exhibits superior performance (10 mA cm −2 @ 1.30 V RHE ), achieving complete HMF conversion at 1.45 V RHE , with both FDCA yield and Faradaic efficiency reaching 98 %. It also demonstrates excellent practical applicability in an MEA reactor and generality for various organic substrates. Electrochemical analysis, in situ characterization and DFT calculations collectively confirm: BEF optimizes the electronic structure of Lewis acid sites, enhancing the selective adsorption of Lewis bases (OH - /HMF and other intermediates), triggering CuCo 2 O 4 surface reconstruction into CoOOH, simultaneously accelerating the cyclic turnover of CoOOH after chemically oxidizing HMF, promoting PCET, and thus enabling an efficient indirect oxidation pathway with lowered energy barriers. This work reveals the crucial role of rational BEF design in modulating Lewis acid sites and optimizing the “adsorption-activation-desorption” of substrates, providing a novel universal strategy for accelerating the PCET kinetics of the oxidation reactions of HMF and other complex nucleophiles.

Porous Bi-doped ceria (Ce1−xBixO2−δ solid solution) was prepared by the easy citrate method and then used as a supporting material for Au nanoparticles (NPs) obtained by deposition–precipitation. In the presence of O2, Ce1−xBixO2−δ (0.08 ≤ x ≤ 0.5) efficiently catalyzed the conversion of 5-hydroxymethylfurfural (HMF) to 5-hydroxymethyl-2-furancarboxylic acid (HFCA) and 2,5-bishydroxymethylfuran (BHMF) in alkaline aqueous solution without degradation of HMF. The excellent catalytic activity was attributed to the oxygen activation and hydride transfer enhanced by Bi doping and the large amount of oxygen vacancies. After Au NPs were supported on Ce1−xBixO2−δ (x ≤ 0.2), the presence of Auδ+ facilitated the activation of the C–H bond in the hydroxymethyl group and then the production of 2,5-furandicarboxylic acid (FDCA) as an end product, inhibiting the generation of BHMF.

Supported metal catalysts play a significant role in the selective organic synthesis and valorization of bio-derived platform molecules, and the development of catalyst preparation method is an important research topic. The facile in situ reduction synthesis strategy was investigated to prepare gold catalysts on Ti3AlC2-derived nanofibrous materials, using “as-produced H2” during hydrothermal synthesis as a reductive agent. The results of catalyst characterizations revealed that the metallic Au NPs (gold nanoparticles) were loaded with high efficiency. The new series of Aupre/Ti3AlxC2Tycatalysts as prepared by the in situ reduction method generally exhibited higher conversions in the selective oxidation of biomass-derived HMF (5-hydroxymethylfurfural) and aromatic alcohols, outperforming the traditional series of Audp/Ti3AlxC2Tycatalysts as made by the deposition–precipitation method. The HMF conversion was 96.9% over 2%Aupre/Ti3AlxC2Tyand was 76.9% over 2%Audp/Ti3AlxC2Ty. The HMFCA (5-hydroxymethyl-2-furan carboxylic acid) selectivity over these two catalysts was almost identical, whereas it was 96.3% over 1%Aupre/Ti3AlxC2Tyand 84.3% over 1%Audp/Ti3AlxC2Ty. The catalyst reusability tests proved that the typical catalyst Aupre/Ti3AlxC2Tymaintained reaction rates and product selectivity in at least three cycles, whereas the reusability of Audp/Ti3AlxC2Tycatalyst was relatively weaker in both reactions. Finally, the plausible catalytic mechanism was discussed according to peer studies and the research results.

A simple solid base catalyst, ammonium aluminum carbonate hydroxide (AACH), was prepared and its structure was characterized by many technologies, including XRD, FT-IR, SEM, BET and Elemental Analysis. The prepared catalyst was used to catalyze the conversion of glucose into 5-hydroxymethylfurfural (HMF) in ionic liquid 1-butyl-3-methylimidazolium chloride ([Bmim]+Cl–) and dimethyl sulfoxide (DMSO) mixtures. Various reaction conditions, including catalyst loading, reaction temperature, reaction duration and solvent, were investigated. A moderated HMF yield of 52.17 % was obtained at the mild reaction conditions (120°C for 4 h). More importantly, the catalyst could be reused for several times without the loss of its significant catalytic activities. After five reaction runs, a HMF yield about 49.34 % was also obtained.
