Selective ring-opening hydrogenolysis of furfural (FF) to 1,5 pentanediol (1,5-PeD) is crucial for biomass valorization. However, achieving accurate bond-breaking is challenging. Herein, we report a facile method to synthesize layered double hydroxide nanoflake (ZnCo-LDH) mediated via Co 2+ etching ZIF-8 with NaBH 4 in water at ambient temperature. The structure, morphology, and chemical properties of synthesis catalysts with different concentrations of Co 2+ were characterized. The results indicated a partial ZIF-8 structure in ZnCo-LDH, with increased Co 2+ concentrations leading to catalyst agglomeration. Furthermore, the constitutive relationships between the catalyst’s properties and 1.5-PeD yields were established. Moreover, Co introduction altered the catalyst surface’s Brønsted and Lewis acids content. Density functional theory (DFT) indicated enhanced H 2 adsorption and dissociation due to electro-transfer between Co and Zn species, with a tilted configuration favoring ring opening. Finally, a possible reaction mechanism was proposed. This work provides valuable insights for preparing ultrathin nanoflake ZnCo-LDH catalysts for biomass-derived furfur compound upgrading.

Reliable power supplies at extremely high temperatures are urgently needed to broaden the application scenarios for electric devices. Aqueous zinc metal batteries (ZMBs) with intrinsic safety are a promising alterative for high-temperature energy storage. However, the reversibility and long-term cycling stability of aqueous ZMBs at extremely high temperatures (≥100 °C) have rarely been explored. Herein, we reveal that spontaneous Zn corrosion and severe electrochemical hydrogen evolution at high temperature are vital restrictions for traditional aqueous ZMBs. To address this, a crowding agent, 1,5-pentanediol, was introduced into an aqueous electrolyte to suppress water reactivity by strengthening O–H bonds of H2O and decreasing H2O content in the Zn2+ solvation sheath, while maintaining flame resistance of the electrolyte. Importantly, this electrolyte enabled reversible Zn deposition with a Coulombic efficiency of 98.1% and a long cycling life of Zn//Zn batteries for over 500 cycles (at 1 mA cm–2 and 0.5 mAh cm–2) at 100 °C. Moreover, stable cycling of Zn//Te full batteries at 100 °C was demonstrated.

Graphical The CoO@Co core-shell catalyst, 7Co-0.2Fe/CeO 2 , efficiently catalyzes the hydrogenation and ring-opening of furfural to 1,5-pentanediol, with a high productivity of 54.76 mmol/g Co /h, representing the top activity level among the reported catalysts. The addition of Fe optimizes the Co 2+ /Co 0 ratio, improves substrate adsorption, and prevents the formation of tetrahydrofurfuryl alcohol, a saturated furan byproduct. In the conversion of furfural using non-noble metal catalysts, preferential cleavage of the C2−O bond followed by hydrogenation of the C=C bond facilitates selective access to valuable 1,5-pentanediol (1,5-PeD). Herein, we developed CeO₂ loaded core-shell CoO@Co nanoparticle catalysts. Adjusting Co loading, Fe doping, and reduction temperature improved reaction efficiency. 7Co-0.2Fe/CeO₂ catalysts reduced at 500 °C demonstrated optimal performance. 1,5-PeD produced at 54.76 mmol/g Co /h, representing the top activity levels among the reported catalysts. H₂-TPR, XRD, HAADF-STEM, FT-IR, XPS, and XANES were employed to investigate the catalyst structure-activity relationship. Co 2+ cleaves furan ring C−O bond, Co⁰ promotes double-bond hydrogenation. The CoO@Co structure favors the desired 1,5-PeD production route. Trace Fe species optimize the Co 2+ /Co⁰ ratio, enhance the substrate adsorption, and inhibit the furan ring saturation. These findings emphasize the importance of fine-tuning catalyst structure and composition for selectivity improvement.

Direct hydrogenolysis of biomass-derived furfural to produce 1,5-pentanediol, an essential precursor for polyesters and polyurethanes, plays a significant role in biomass utilization. In this work, using the carbothermal shock strategy, 1.5PtCo1Ce1-CTS ternary metal oxides were successfully prepared, containing abundant oxygen vacancies (Ov) and Co2+ species that are favorable for hydrogen transfer and ring-opening of furan, thereby enhancing catalytic activity and 1,5-pentanediol selectivity. Under an optimized condition (170 °C, 3 MPa of H2, 4 h), the 1.5PtCo1Ce1-CTS catalyst achieved furfural conversion at 99.3% and 1,5-pentanediol selectivity at 59.2%. During recycling tests, the 1.5PtCo1Ce1-CTS catalyst exhibited high resistance to deactivation with a simple and rapid regeneration process. This work offers an alternative, versatile, and eco-friendly strategy for designing efficient heterogeneous catalysts for the hydrogenolysis of furfural into 1,5-pentanediol in the future.

Tetrahydrofurfuryl alcohol, a cost-effective biomass derivative, offers a sustainable path for synthesizing 1,5-pentanediol through hydrogenolysis. To develop the efficient production of 1,5-pentanediol from this alcohol, we have prepared a series of MgAl2O4-modified Pt/WOx/γ-Al2O3catalysts with varying compositions via impregnation–calcination methods. The physicochemical properties of these catalysts were subsequently characterized using diverse techniques. Characterization revealed that magnesia–alumina spinel modification enhanced Pt particle dispersion, CO adsorption on Pt/WOx/γ-Al2O3, reduced Pt particle reduction temperature, diminished the acid content in the catalysts, and increased the surface oxygen vacancy concentration. These alterations appear to influence the catalyst performance, though other factors cannot be ruled out. Catalytic activity tests demonstrated that magnesia–alumina spinel modification improved tetrahydrofurfuryl alcohol hydrogenolysis activity and the 1,5-pentanediol selectivity of Pt/WOx/γ-Al2O3. Optimal performance was achieved at 12% magnesia–alumina spinel loading, with a tetrahydrofurfuryl alcohol conversion of 47.3% and 1,5-pentanediol selectivity of 88.4%.

The ability to effectively control furan ring opening is the key to transforming furfural into 1,5-pentanediol. Herein, a series of Co-based catalysts modified with rare-earth metals (Y, Pr, La, and Ce) were synthesized. It was found that Y-modified Co-based catalyst with a Co/Y molar ratio of 3.5/0.5 exhibited the highest selectivity for 1,5-pentanediol (53.7%) at 150 °C and 4 MPa H2 in isopropanol (time = 5 h). Coordination between Co and Y in the catalyst resulted in more CoOx and oxygen vacancies, which are vital factors for cleaving the C–O bond of the furan ring. In addition, highly dispersed small-sized Co0 particles on the catalyst surface could boost the dissociation of H2 molecules, which attacked the carbonyl group in the furan ring of furfural to afford 1,5-pentanediol. Density functional theory calculations revealed that the presence of CoOx/Y2O3 oxide interfaces promoted adsorption of furfural (especially via the furan ring) and hydrogenolysis during the hydrogenation process. Modifying a Co-based catalyst with rare-earth metals offers a novel approach for producing 1,5-pentanediol from furfural.

The utilization of 1,4-butanediol (BDO) spans across numerous sectors, underscoring its significance as a pivotal chemical. However, the separation of crude BDO still presents great challenges. Ethylene glycol (EG) and 3-methyl-1,5-pentanediol (MPD) are classical impurities in BDO crude products. In this paper, the pressure and temperature data of MPD components under high vacuum pressure were measured, and Antoine constant was obtained by fitting to supplement the basic data. The isobaric vapor-liquid equilibrium (VLE) data for the EG-BDO and BDO-MPD mixtures were experimentally measured at pressures of 1.0, 10.0, and 50.0 kPa. Meanwhile, the thermodynamic consistency of the experimental binary data was examined using the Herington area test. The experimental VLE data for binary systems were analyzed using the nonrandom two-liquid (NRTL) universal quasichemical (UNIQUAC) and Wilson activity coefficient models, demonstrating that the predicted outcomes showed excellent agreement with the measured data. Finally, the interaction energy between the components was calculated by molecular simulation to explain the gas-liquid equilibrium behavior. Therefore, this work provided guidance and basis for the separation of EG-BDO and BDO-MPD in high vacuum separation.

Several aliphatic long chain polyesters with intrinsic viscosity of 0.80-1.47 dL/g were synthesized from biobased 1,5-pentanediol and long chain α,ω-diacids with 10-16 carbon atoms. Their chemical structure was characterized, and thermal, mechanical and gas barrier properties were assessed. These long chain polyesters have a melting temperature higher than poly( ε -caprolactone) and manifest polyethylene-like rapid crystallization, good thermal stability and ductile tensile behavior. Their melting temperature, crystallizablity, tensile modulus and oxygen and water vapor barrier performance all increase with increasing the chain length of diacid. In comparison with the widely used biodegradable poly(butylene adipate-co-terephthalate) copolyester, these potentially biodegradable polyesters show comparable tensile strength, ductility and oxygen barrier performance, but obviously superior crystallizability, tensile modulus and water vapor barrier performance.

The catalytic conversion of biomass-derived furfural and its derivatives such as furfuryl alcohol (FFA) into high value-added chemicals has been the subject of considerable attention within the field of biomass refining. Nevertheless, the selective hydrogenolysis of FFA represents a significant challenge to obtain the goal product such as 1,2-pentanediol (1,2-PeD) or 1,5-pentanediol (1,5-PeD) with satisfactory yield, due to complicated network involved in the FFA hydrogenolysis. Hence, selectivity control is the key to the hydrogenolysis of FFA. In this work, a 45Ni-Pr (45 wt% Ni/PrO x ) catalyst prepared using a facile sol–gel method behaved very well in the hydrogenolysis of FFA, resulting in up to 86.3 % yield of 1,5-PeD under mild reaction conditions. Introduction of PrO x enhanced Ni dispersion and promoted intimate contact between Ni species and PrO x . This created weak and medium-strong basicity and oxygen vacancies on the catalyst surface, which facilitated the adsorption of FFA via the C-O-C bond on the furan ring and C-OH at the side chain. Moreover, the 45Ni-Pr catalyst had the balanced Ni 0 and Ni 2+ sites, which guarantee not only the saturation of the C=C bond on the furan ring in the presence of Ni 0 sites to yield the intermediate tetrahydrofurfuryl alcohol (THFA), but also the subsequent ring-opening hydrogenolysis of THFA at the Ni 0 -O V -Ni 2+ -PrO x interfacial sites to produce 1,5-PeD selectively. This work establishes a viable and environmental benign approach for producing 1,5-PeD from the bio-based furfural derivatives, as well as a reference for the selective ring-opening hydrogenolysis of furan compounds.

Biomass-derived furfural and its derivatives are promising feedstocks for producing valuable C 5 diols by catalytic hydrolysis. However, this process requires selective ring opening of tetrahydrofurfuryl alcohol (THFA) to 1,5-pentanediol, which is challenging. Here we report efficient route for this conversion using Ni-La(OH) 3 catalysts prepared by a green co-precipitation-hydrothermal method. We show that these catalysts can achieve up to 91.7% yield and 94.6% selectivity of 1,5-pentanediol from THFA under mild conditions. We elucidate the key role of the La(OH) 3 phase, the basic sites and the Ni n+ -O-La 3+ structure of the catalysts in promoting the selective hydrogenolysis and ring opening of THFA. We also demonstrate that the co-dehydrogenation of secondary alcohols enables lower reaction pressure and longer catalyst lifetime. Our work provides a sustainable and environmentally benign approach for producing 1,5-pentanediol from biomass-based furfural and its derivatives, which has potential applications in polymer synthesis and green chemistry.

The selective activation of targeted bonds within renewable biomass-derived furanic compounds for the production of high-value alkyl diols holds significant importance for biomass upgrading, necessitating well-defined catalysts and clearly defined catalytically active sites. Herein, 1,5-pentanediol is synthesized through the selective hydrogenolysis of furfural-derived tetrahydrofurfuryl alcohol utilizing Ni-Co/La(OH) x bimetallic catalysts. The La(OH) x with abundant defect sites polarizes Ni-Co alloy for heterocracking of H 2 , as well as leads to expose more interfacial NiCo-O V -La 3+ sites. By harnessing the synergistic interplay between the alloy sites and the interfacial sites, the optimized Ni 4 Co 1 /La(OH) x bimetallic catalyst markedly enhances the adsorption of –OH groups in tetrahydrofurfuryl alcohol and facilitates the selective assault of active H species on the C-O-C bonds within tetrahydrofuran rings. This approach markedly elevates the selective hydrogenolysis of tetrahydrofurfuryl alcohol to 1,5-pentanediol, attaining an exceptional selectivity of 88.6 % with a conversion of 98.1 % for tetrahydrofurfuryl alcohol. Furthermore, the Ni 4 Co 1 /La(OH) x bimetallic catalyst demonstrates exceptional performance in the one-pot hydrogenation-hydrogenolysis of furfural to 1,5-pentanediol, exhibiting a low activation energy of 17.77 kJ/mol and a high turnover frequency of 192.1 h −1 . Notably, the Ni 4 Co 1 /La(OH) x bimetallic catalyst showcases remarkable stability. This outcome provides invaluable insights for the advancement of a sustainable process to produce diol monomers from renewable resources with a low carbon footprint.

Production of alkyl diols from biomass-derived furanic compounds by hydrogenolysis is a promising route to the fabrication of bio-based polyesters and polyurethanes. However, it faces many challenges such as the use of noble metal catalysts, or low hydrogenolysis activity of the furan rings and poor product selectivity with non-noble metal catalysts. In this work, non-noble metal catalysts Cu-Co 3 O 4 (CuCo x ) catalysts were modified by magnesium, obtaining CuCo x Mg y catalysts with tunable surface oxygen vacancies (OV). The CuCo x Mg y catalysts demonstrated greatly improved activity and selectivity (approx. 50 %), comparable to those of noble metal catalysts, in the hydrogenolysis of furfuryl alcohol into 1,5-pentanediol (1,5-PeD). The obtained CuCo x Mg y catalysts are even superior to the noble metal catalysts in terms of production rate or productivity. Extensive characterizations including XAS, EPR and XPS revealed that magnesium significantly promotes the formation of Co 2+ -OV pair sites on the catalyst surface, which simultaneously activate furan ring and hydroxyl group in furfuryl alcohol, leading to the efficient and selective cleavage of the C 2 -O 1 bond to form 1,5-PeD. The CuCo x Mg y catalysts also exhibited high activity and selectivity in hydrogenolysis of various other biomass-derived furanic compounds towards ring-opening products.
