Petroleum-based monomers, such as terephthalic acid (TPA), are extensively utilized in the manufacture of disposable packaging materials. In light of the rapid depletion of fossil fuel resources and the escalating environmental challenges, the development of bio-based monomers and polymers have gained significant momentum. Among them, 2,5-furandicarboxylic acid (FDCA) is widely recognized as a sustainable substitute for TPA. However, FDCA-based polyesters often suffer from limitations in toughness. Herein, we report the synthesis of poly(hexamethylene furandicarboxylate-4-hydroxy-N-(2-hydroxyethyl)pentanamide) (PHHFx) through the integration of 4-hydroxy-N-(2-hydroxyethyl)pentanamide (HHPA) into the polymer chain. The incorporation of HHPA facilitates the formation of hydrogen-bonded crosslinked network in PHHFx, effectively enhancing the mechanical performance (i.e., ε b and σ b are 382.9% and 38.2 MPa) and gas barrier properties (i.e., O 2 0.008 barrer, CO 2 0.024 barrer, and H 2 O 1.53×10 -14 g·cm·cm -2 ·Pa -1 ·s -1 ). In addition, PHHFx exhibit efficient chemical recyclability under mild conditions, achieving high monomer recovery yields. This work demonstrates a viable strategy for designing high-performance, chemically recyclable bio-based polyesters, addressing both the pressing energy crisis and environmental pollution challenges.

The electrocatalytic oxidation of 5-hydroxymethylfurfural (HMF) to 2,5-furandicarboxylic acid (FDCA) is considered to be the most promising way to achieve green conversion of biomass resources in industrial production. Herein, a series of CuxCo3–xO4 (0 ≤ x ≤ 1) nanofibers are obtained using an electrospinning method, with discovering the role of Cu/Co interactions in modulating the electronic structure of reaction sites and acidic sites for enhancing the intrinsic activity of HMF electro-oxidation (HMFOR). According to the characterizations and theoretical calculations, the reasonable ratio of Cu/Co affects the structure of active sites and the exposure of Lewis adsorption sites in the spinel and thus finally determines an outstanding catalytic activity. An appropriate amount of Cu occupying the tetrahedral sites in the Co-based spinel promotes significantly the electrocatalytic property; specifically, Cu0.5Co2.5O4 shows the best performance of HMF with a selectivity of 93% and Faraday efficiency of 91% for FDCA. This work offers a strategy to design highly active catalysts by adjusting the metal composition and provides an insight into the modulation of multimetal active site structures at the atomic scale.

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.

Poly(butylene 2,5-furandicarboxylate) (PBF) is a typical semi-aromatic polyester derived from biomass, synthesized from 2,5-furandicarboxylic acid (FDCA) and 1,4-butanediol (BDO). PBF exhibits excellent mechanical strength and thermal stability, making it a promising eco-friendly alternative to petroleum-based plastics. In this study, trans-1,4-cyclohexanedicarboxylic acid (CHDA) was introduced to modulate the structure and properties of PBF. A series of poly(butylene 2,5-furandicarboxylate- co -cyclohexanedicarboxylate) (PBFC) random copolyesters were successfully synthesized via two-step melt polymerization. The results show that PBFC random copolyesters possess high thermal stability. More importantly, the crystallization behavior, crystal structure, and micromorphology of PBFC can be systematically tuned by varying the CHDA content. Notably, PBFC can realize the transformation from crystalline polyester to amorphous polyester by adjusting the content of CHDA. This tunable crystallinity endows PBFC with a wide range of mechanical properties, from rigid plastics to elastomers, making them suitable for diverse applications such as rigid packaging, flexible packaging, and high-performance bio-based elastomers.

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.

Renewable electricity-powered electrooxidation of 5-hydroxymethylfurfural (HMFOR) to FDCA offers a green and sustainable approach to producing an essential monomer for bio-polymers, provided that a highly efficient electrocatalyst is present. Herein, we show that the doping of scandium (Sc) into an NiFe-LDH electrocatalyst (Sc-NiFe-LDH) considerably promotes HMFOR by enhancing the formation of high-valence NiIII–O active sites, facilitating electron transport and HMF adsorption and suppressing the oxygen evolution reaction. In the presence of the Sc-NiFe-LDH electrocatalyst, an FDCA faradaic efficiency and selectivity of 96.5% and 99.5%, respectively, were achieved at a current density of >600 mA cm−2. The high performance of the Sc-NiFe-LDH electrocatalyst is the best among those of other reported electrocatalysts for this reaction, showing great promise in upgrading biomass to valuable chemicals. This work would inspire further studies on the rational design of novel and efficient electrocatalysts for green and sustainable energy transformations.

A serials of fully bio-based poly(ethylene dodecanedioate-2,5-furandicarboxylate) (PEDF) were synthesized from Dodecanedioic acid (DDCA), 2,5-Furandicarboxylic acid (2,5-FDCA), and ethylene glycol through a two-step procedure consisted of transesterification and polycondensation. After their chemical structures were confirmed by Nuclear Magnetic Resonance and Fourier Transform Infrared Spectroscopy, their thermal, mechanical, and biodegradation properties were investigated in detail. Results showed that the chemical composition of PEDFs could be easily controlled by the feeding mole ratio of DDCA to FDCA and they possessed the characteristic of random copolyester with the intrinsic viscosity ranged from 0.82 to 1.2 dL/g. With the varied mole ratio of DDCA to FDCA, PEDFs could be changed from semicrystalline thermoplastic to the completely amorphous elastomer, indicated by the elongation at break ranged from 4 for poly(ethylene 2,5-furandicarboxylate) to 1500% for amorphous PEDF-40. The amorphous PEDF-30 and PEDF-40 showed satisfactory shape recovery after cyclic tensile test, which was the typical behavior for elastomer. Enzymatic degradation test indicated that all the PEDFs were biodegradable and the degradation rate was heavily affected by their chemical compositions. © 2017 Wiley Periodicals, Inc. J. Appl. Polym.

A series of poly (propylene naphthalate-co-propylene 2,5-furandicarboxylate)s (PPNFs) were synthesized by the melt polycondensation method from 2,5-furandicarboxylic acid (FDCA), 2,6-naphthalenedicarboxylic acid (2,6-NDCA) and 1,3-propanediol (1,3-PDO). Their composition and sequence distribution were analyzed by 1 H NMR and 13 C NMR. Crystallization behaviors , thermal and mechanical properties were investigated. The weight-average molecular weights of PPN, PPF and PPNFs were higher than 28 000 g mol −1 and the polydispersity index was between 2.1 and 2.7. DSC and XRD results show that poly (propylene 2,5-furandicarboxylate) (PPF) and poly (propylene naphthalate) (PPN) are semi-crystalline polymers, but all PPNFs are amorphous polymers. With increasing the content of FDCA, the initial temperature of α-relaxation rose significantly. When the content of FDCA was 74 mol%, PPNF74 exhibited the high bio-based content (77.6 wt%) and good mechanical properties ( σ m = 71 MPa and ε b = 146%).

The electrocatalytic oxidation of 5-hydroxymethylfurfural (HMF) represents a promising pathway for producing biomass-derived value-added chemicals. Nevertheless, the use of extremely expensive ion exchange membranes (IEMs) as separators significantly sacrifices the economic benefit in large-scale applications. Herein, we report a cost-effective non-fluorine cation exchange membrane (CEM) by grafting sulfonic acid (-SO 3 - ) groups onto the aromatic side chain of the polyethersulfone (PES) polymer. By tuning the content of –SO 3 - groups, the physicochemical properties of the resulting CEMs can be easily adjusted. Impressively, the optimal HBS-PES-1.0 CEM with fully grafted –SO 3 - groups can achieve a high HMF conversion of 100 %, FDCA selectivity of 98.0 %, and Faradaic efficiency of 98.3 % when used as the separator for electrocatalytic oxidation of HMF, surpassing that of the commercial Nafion 117 membrane (100 % HMF conversion, 98.1 % FDCA selectivity, and 97.4 % Faradaic efficiency). This study provides a cost-effective and high-performance CEM as a substitute for the expensive commercial membrane, paving the way to large-scale commercial applications of biomass upgrading through the electrolysis process.

Hydrolysis of cellulose into C 6 sugars is the starting point and entry point for biomass refining and is an important pathway for biofuel production. However, biomass-based 2,5-furandicarboxylic acid (FDCA) is a highly catalytic promising but underutilized organic carboxylic acid. In this paper, we investigated the use of easily recoverable FDCA as a catalyst for the hydrolysis of cellulose to produce C 6 sugars in a γ-valerolactone/water (GVL/H 2 O) green solvent system. FDCA has high inherent acidity (pKa = 2.76) and stability with unique solubility in aqueous solutions and many solvents. These properties allows it to meet both high temperature solubility for efficient homogeneous hydrolysis reactions and low temperature crystallization catalysts for high purity recovery. This process not only solves the problem of solid-solid mass transfer between solid acid and cellulose which limits the hydrolysis rate, but also eliminates the problem of difficult separation and recovery of liquid acid catalysts. The results showed when initial concentration of microcrystalline cellulose was 0.7 wt%（equivalent to 7 g/L）, and the initial dosage of FDCA was 2.0 wt%, the maximum yield of C 6 sugars reached 72.9% (40.1% glucose and 32.8% fructose) in GVL/H 2 O (60/40, V/V) with a reaction at 200 °C for 30 min. More importantly, FDCA can achieve 80% recovery and ＞99% spectroscopic purity recovery. This study reveals the potential of FDCA as a catalyst in the catalytic conversion of biomass, which provides a new pathway for the green and efficient conversion of biomass resources.

Dense CuO x -CoO y nano-heterostructures were uniformly assembled on the surface of graphene via surfactant induced assembly and hydrolysis with the presence of PVP and NaBH 4 . As-prepared CuO x -CoO y -PVP/G composite exhibited excellent performance for selective oxidation of 5-HMF to FDCA in aqueous solution with NaClO as oxidant at 30 °C, which is comparable to noble metal catalysts. The outstanding performance can be attributed to fascinating synergetic contributions from the CuO x -CoO y heterostructure on graphene substrate, giving improved interfacial contact, increased active sites and accelerated electron transfer process to promote the catalytic reaction. This work provides a high-performing catalyst for oxidation of 5-HMF to FDCA, as well as an ideal design of metal-oxide heterostructures/graphene composite catalysts for more broad applications.

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.
