High glass transition temperature polymers are extensively used in many fields such as packaging, electronic products, and automobiles. However, most of them are expensive as synthesized in polar aprotic solvent with low solid percent. The task of effectively synthesizing high glass transition temperature polymers faces at least three important challenges: the need for a solvent-free process to reduce cost and pollution, the requirement for a thermoplastic process with a high glass transition temperature above 150 °C, and the use of monomers derived from renewable resources. Traditional polyesters can be prepared via melt polycondensation, but achieving a glass transition temperature above 130 °C while maintaining good mechanical properties remains challenging. In this work, we developed a strategy to synthesize a new high glass transition temperature polyesters by employing rigid bulky diol of 9,9-bis [6-(2-hydroxyethoxy)naphthyl]fluorene (BNEF) and bio-based 2,5-furandicarboxylic acid (FDCA) which derived from fructose or furfural, as the main monomers. The new copolyesters exhibit a glass transition temperature of up to 164.2 °C, a number-average molecular weight of 24,600 g/mol, along with tensile modulus and strength values of 3030 MPa and 134 MPa, respectively. Furthermore, the copolyesters exhibit excellent transparency properties of 88.4 % by cutoff at 700 nm and well solvent resistance, which could serve as new low-cost, high-performance engineering plastics with ultra-high glass transition temperature and transparency.

Membrane separator that is highly ionic conductive and alkaline stable is essential for the efficient, scalable electrocatalytic oxidation of HMF to FDCA, a key process for sustainable development. Drawing inspiration from the microstructural design of Nafion, we developed a series of side-chain imidazolium-functionalized anion exchange membranes (AEMs), employing the chemically stable polyethersulfone (PES) as the base polymer. Functionalization of PES side chains with chloromethyl groups, followed by C2-substituted imidazolium modification, enabled precise tuning of the membrane's physicochemical properties and structural characteristics. This tailored approach yielded an optimized DIM-PES-1.0 AEM exhibiting complete HMF conversion, with 94.0 % selectivity for FDCA and 94.1 % Faradaic efficiency, outperforming the commercial Fumasep FAA-3-PK-130 AEM, which achieved only 85.5 % FDCA selectivity under similar conditions. Notably, the DIM-PES-1.0 AEM demonstrated high alkaline stability, substantially retaining its electrocatalytic activity across 15 cycles, in contrast to the rapid degradation observed in FAA-3-PK-130 AEM after only three cycles. Our findings showcase a scalable, efficient strategy for producing high-performance AEMs under mild conditions, highlighting their potential for advancing sustainable electrocatalytic processes.

Graphical A green and sustainable −COOH & −OH condensation solution polymerization method for FDCA-based polyesters. A green and sustainable −COOH & −OH condensation solution polymerization method was hereby reported for FDCA-based polyesters to avoid discoloration and toxic solvents. First, taking poly(ethylene 2,5-furandicarboxylate) (PEF) as the representative of FDCA-based polyester, enabling good white appearance PEF with M n =6.51×10 3 g mol −1 from FDCA and ethylene glycol in green solvent γ-valerolactone (GVL), catalyzed by 4-dimethylaminopyridine (DMAP) and N-(3-dimethylaminopropyl)-N’-ethylcarbodiimide hydrochloride (EDC). Additionally, the molecular weight of PEF was rapidly improved ( M n >2.5×10 4 g mol −1 ) via remelting polycondensation within minutes, with the dispersity still kept relatively low dispersity ( Đ <1.40). Importantly, the −COOH & −OH condensation solution polymerization method was successfully applied for the synthesis of various FDCA-based polyesters, including diols with varying carbon chain lengths (3 to 11 carbons) and cycloalkyl diols, especially the applicability of this method to diols containing C=C double bonds, which was found to exhibit low heat resistance. Lastly, assisting with 13 C labeled 1,4-succinic acid and in-situ 13 C-NMR, an in-depth study of the possible catalytic mechanism was proposed, by which, EDC activated FDCA, and then DMAP catalyzed it with diol to yield macromolecular chain of polyester. Overall, the results provided a green and sustainable strategy for the synthesis of FDCA-based polyesters.

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.

Heat-resistant semi-aromatic poly (decamethylene terephthalamide) acid (PA10T) and a series of poly (decamethylene terephthalamide/decamethylene furanamide) (PA10T/10F) with a high content of bio-based carbon were synthesized by a cost-effective high-pressure solution polycondensation method. The chemical structures of the obtained samples were evaluated by Fourier infrared spectroscopy (FT-IR). Moreover, the effect of the addition of copolymer 2,5-furandicarboxylic acid (FDCA) and the copolymerization ratios of FDCA for PA10T on thermal performances, crystallization behaviors, and mechanical properties of PA10T and PA10T/10F were studied in detail. In addition, the results of DSC indicate that the melting points of PA10T/10F copolyamides can be adjusted appropriately by varying the feed ratios of FDCA, suggesting the improvement of processabilities. Besides, with increasing the copolymerization ratios of FDCA, the sizes of spherulites decreased gradually analyzed by POM. Furthermore, the results of XRD showed that the PA10T homopolymer and PA10T/10F copolyamides possess similar shapes around 2θ = 21°. In addition, compared with pure PA10T, the tensile strength, breaking elongation, bending strength, bending modulus, and izod impact strength all increased obviously when the feed ratio of FDCA and terephthalic acid (PTA) was 5:95. Therefore, the crystallization behaviors, processing performances, and mechanical characteristics of PA10T can be improved significantly by introducing FDCA, to improve the bio-based carbon content of PA10T and meet the increasing demand for environmentally friendly materials all over the world.

Oxygen vacancies play an important role in the oxidation of biomass-derived alcohols and aldehydes using ceria-based catalysts. In this study, a highly oxygen vacancy-defective Pt/H-CeO 2 catalyst was synthesized by a straightforward strategy that involved the control of the addition of ascorbic acid and nitric acid. The addition of ascorbic acid, which acted as a pore-forming agent, promoted the hydrolysis, crystallization, and subsequent growth of Ce precursor salt, resulting in the synthesis of H-CeO 2 with abundant oxygen vacancy defects and a porous thin sheet-like morphology. However, the addition of nitric acid significantly inhibited the generation of oxygen vacancy defects. The obtained H-CeO 2 exhibited significantly increased oxygen vacancy content, active oxygen species, and specific surface area compared with CeO 2 with lower oxygen vacancy defects (L-CeO 2 ). These remarkable features led to enhanced catalytic activity of Pt/H-CeO 2 for the oxidation of 5-hydroxymethylfurfural (HMF) compared with Pt/L-CeO 2 . This can be mainly attributed to the enhanced adsorption and activation of O 2 molecules by abundant oxygen vacancies, allowing more active oxygen species to participate in the dehydrogenation of HMF. This work provides an example of oxygen defect engineering for ceria-based catalysts to boost the catalytic selective oxidation performance.

Graphical Saving face : Catalytic performance of Au/CeO 2 with different exposed CeO 2 crystal faces for oxidation of 5-hydroxymethlfurural to 2,5-furandicarboxylic acid is dependent on the oxygen vacancy (V O ) concentration. Higher V O concentration of Au/rod-CeO 2 (110) is more beneficial for adsorption of oxygen and formation of active oxygen species than Au/cube-CeO 2 (100) and Au/oct-CeO 2 (111). Developing an efficient catalyst to upgrade 5-hydroxymethylfurfural (HMF) to high-value-added downstream chemicals is of great significance in biomass conversion. Nanorod (110)-, nanocube (100)-, and nanooctaheron (111)-CeO 2 -supported Au nanoparticles were prepared to investigate the intrinsic effect of CeO 2 crystal faces on the oxidation of HMF to 2,5-furandicarboxylic acid (FDCA). The experimental results and density functional theory calculation revealed that the concentration of oxygen vacancy (V O ) for exposed specific crystal faces was crucial to the oxygen adsorption ability, and Au/nanorod-CeO 2 with the highest V O concentration promoted the formation of more oxygen active species (superoxide radical) on CeO 2 (110) crystal face than (100) and (111) crystal faces. Besides, the higher V O concentration could provide a strong adsorption ability of HMF, greatly boosting the activation of HMF. Thus, these results led to a superior catalytic activity for HMF oxidation over Au/nanorod-CeO 2 (FDCA yield of 96.5 %). In-situ Fourier-transform (FT)IR spectroscopy uncovered the HMF oxidation pathway, and the possible catalytic mechanism was proposed. The deep insight into the role of regulation for crystal faces provides a basis for the rational design of highly active facets for the oxidation of HMF and related reactions.

5-Hydroxymethylfurfural (HMF) serves as an important bridge connecting biomass resources with fossil fuels. Its downstream product, 2,5-furandicarboxylic acid (FDCA), is a renewable alternative to terephthalic acid (TPA) in the synthesis of various polymer materials. In this study, we successfully synthesized four ruthenium-based catalysts with varying valence states supported on carbon nanotubes (CNTs) and compared the performance of HMF electrooxidation. Among these, the Ru+2.9catalyst demonstrated the highest activity for the electrochemical oxidation of HMF to FDCA in the neutral medium (0.1 M K2SO4). Notably, the FDCA yield reached 90.2% under an applied potential of 0.95 V (vs. Ag/AgCl) after 24 h. Mechanistic analysis revealed that the superior specific capacitance of the Ru+2.9catalyst significantly facilitated the reaction process. This work represents a more cost-effective approach to avoid the need for excessive alkaline additives during catalyst preparation and the HMF oxidation process, and FDCA separated easily after cooling the reaction solution down.

Interface engineering is a significance strategy to afford efficient selective oxidation for supported catalysts. Herein, constructing of frustrated Lewis pairs (FLPs) sites on CeO 2 and supporting Au-Pd nanoparticles to provide a highly selective production of 2,5-furandicarboxylic acid (FDCA) from 2,5-bis(hydroxymethyl)furan (BHMF). Mechanism investigations illustrate that the FLPs active sites enhance the adsorption and activation of catalyst for BHMF, decreasing the activation energy of rate-determining step. Simultaneously, the FLPs sites induce the electron transfer of the catalyst, generating a novel Au-Pd-CeO 2 interface that promotes the adsorption of molecule oxygen and the formation of the superoxide radical. Thereby, the Au x Pd y /P T -CeO 2 catalysts enable superior catalytic performance, achieving a satisfactory turnover frequency of 55.29 h −1 and a highly FDCA yield of 94.0 %. Such interfacial FLPs sites exhibit the great potentials for the selective oxidation of various unsaturated compounds.

Graphical This study develops a solid-state thermal (SST) synthesis method for the one-step preparation of MOF-derived Mn x @NC catalysts. Among these, the optimal catalyst (Mn 2.5 @NC) exhibits excellent activity, remarkable stability, and good recyclability for HMF oxidation to FDCA, achieving an FDCA yield of 94 % within 4 h at room temperature and maintaining its catalytic performance for five cycles without activity decay. Transforming the bio-based 5-hydroxymethylfurfural (HMF) into its oxidation product 2,5-furandicarboxylic acid (FDCA) offers an attractive route for synthesizing bioplastic monomers. However, significant challenges remain in developing efficient and stable non-precious metal catalysts. Here, we employed a solid-state thermal synthesis (SST) method to design and synthesize a series of metal-organic framework (MOF)-derived metal-nitrogen-carbon (M@NC) materials with gradient metal contents and low metal loadings, labeled as Mn x @NC, for converting HMF into FDCA through oxidation. Further investigations revealed that the amount of metal doping significantly influenced the catalyst structure, particularly in terms of defect quantity and specific surface area. The optimal catalyst, Mn 2.5 @NC, exhibited the largest specific surface area and the highest number of defects, achieving a 94 % FDCA yield within 4 h. Experimental results demonstrated that the recovered catalyst could be reintroduced into the reaction system and maintained selectivity comparable to that of the fresh catalyst for at least five cycles. Moreover, various characterizations of both fresh and recovered catalysts confirmed the great stability of Mn 2.5 @NC. This study provides advanced insights into the effective catalytic conversion of HMF to FDCA and highlights the importance of structural design and regulation in optimizing M@NC catalysts.

A comprehensive investigation was conducted to explore the adsorption behaviors of CH 4 over N 2 on ultra-microporous Al/Zr-FDCA frameworks, which were synthesized specifically using the eco-friendly and bio-sourced 2,5-furandicarboxylic acid (FDCA). Characterization results revealed that both Al-FDCA and Zr-FDCA exhibited similar specific surface area and surface groups, leading to comparable methane uptake per-unit mass at atmospheric pressure. However, the presence of Zr nodes generated ultra-micropores around 0.43 nm in size, leading to a pronounced affinity for CH 4 . Zr-FDCA demonstrated a higher CH 4 /N 2 selectivity (8.90) calculated from the isotherms compared to Al-FDCA (3.86). Furthermore, breakthrough experiments indicated that under the same dynamic conditions, Zr-FDCA exhibited 1.5 times higher CH 4 uptake per unit volume and 2.5 times higher CH 4 /N 2 selectivity when compared to Al-FDCA. Initially, a four-step VPSA process was simulated to investigate the separation of CH 4 /N 2 mixture, in which the effects of feed-gas flow rate, adsorption time, adsorption pressure, and desorption pressure in VPSA cycle were extensively evaluated to enhance the purity and recovery of methane. Subsequently, a six-step process was employed for further optimization, achieving a purity of 95.9 % and a recovery of 99.1 %. The obtained results demonstrated the reliability of the established model and highlighted the significant potential of Zr-FDCA for CH 4 /N 2 separation.

Electrooxidation of 5-hydroxymethylfurfural (HMF) to 2,5-furandicarboxylic acid (FDCA) is a promising strategy for biomass valorization. However, a significant challenge arises from the substantial carbon loss due to spontaneous HMF degradation in alkaline electrolytes, particularly at high concentrations. In this study, we present a straightforward approach to mitigating carbon loss during the electrochemical conversion of HMF to FDCA by suppressing non-Faradaic degradation through low-temperature electrolysis. Notably, under conventional room temperature conditions, carbon losses of up to 25 % can occur, whereas our low-temperature electrolysis method reduces carbon loss to negligible levels (< 1 %) even at high HMF concentrations (up to 500 mM) in highly alkaline electrolyte (2.0 M KOH). This strategy effectively addresses the long-standing challenge of balancing the enhanced kinetics of HMF electrooxidation with the accelerated degradation of HMF as its concentration increases in alkaline media. Our findings highlight the critical role of suppressing non-Faradaic degradation in the efficient conversion of HMF and demonstrate that low-temperature electrolysis offers a viable solution to the challenges of industrial-scale electrochemical biomass valorization.
