Natural binders play attractive roles in stabilizing lithium–sulfur (Li–S) battery systems due to their polymeric skeleton and abundant functional structures, but the complex extraction and modification hinder the practical use. Here, lignocellulose, the unbleached product of the pulp industry, is directly developed as a robust binder in Li–S batteries. Benefiting from various oxygen-containing functional groups woven strong hydrogen-bonded network framework, robust mechanical stability, lithium polysulfide anchoring capacity, and high-speed Li + transport channel. The Li–S cell battery delivers an initial discharge capacity of 996 mAh·g⁻¹ at a current density of 0.5 C and can stably run 500 cycles. Moreover, an Ah-scale pouch cell is constructed and delivers notable gravimetric and volumetric energy densities of 322 Wh·kg⁻¹ and 432 Wh·L⁻ 1 , respectively. This work expands the application boundaries of bulk lignocellulose pulp in advanced energy storage systems.

Oxidative catalytic fractionation (OCF) represents an efficient approach to valorize lignocellulose for coproduction of monophenols and cellulose. To achieve an adequate monophenol yield, lignin oxidation, typically, requires high O2 pressure and an excess of Cu catalysts (the Cu dosage is approximately 3–5 mol equiv relative to the aromatic units in lignin). However, these conditions are relatively harsh for cellulose, resulting in severe decomposition to aliphatic acids. To address the trade-off between the monophenol yield and cellulose production, we develop an enhanced OCF using a CuMnCeO2 solid solution as the catalyst. Under relatively mild conditions (specifically, 0.1 MPa O2), 28.7 wt % monophenols were released from birch, using catalytic amounts of Cu (the Cu dosage was about 0.03 mol equiv relative to the aromatic units in lignin). Meanwhile, up to 83.9% of cellulose was collected as a solid pulp. The synergistic effect between doped metals (Cu and Mn) and oxygen vacancies was found to be crucial for enhanced lignin oxidation under mild conditions with minimized cellulose loss. The abundant surface oxygen vacancies facilitated oxygen activation by well-dispersed Cu and Mn species, while the strong interaction between these metals enhanced the catalyst’s reducibility. Key intermediates such as β-vinyl aryl ethers and byproduct glycolic acid were identified by model experiments, confirming that lignin oxidation primarily followed a 1,2-dioxetane homolysis mechanism. Overall, this enhanced OCF demonstrates the potential viability of lignin oxidation in practical biorefinery applications.

The reductive catalytic fractionation (RCF) of lignocellulose, considering lignin valorization at design time, has demonstrated the entire utilization of all lignocellulose components; however, such processes always require catalysts based on precious metals or high-loaded nonprecious metals. Herein, the study develops an ultra-low loaded, atomically dispersed cobalt catalyst, which displays an exceptional performance in the RCF of lignocellulose. An approximately theoretical maximum yield of phenolic monomers (48.3 wt.%) from lignin is realized, rivaling precious metal catalysts. High selectivity toward 4-propyl-substituted guaiacol/syringol facilitates their purification and follows syntheses of highly adhesive polyesters. Lignin nanoparticles (LNPs) are generated by simple treatment of the obtained phenolic dimers and oligomers. RCF-resulted carbohydrate pulp are more obedient to enzymatic hydrolysis. Experimental studies on lignin model compounds reveal the concerted cleavage of C α –O and C β –O pathway for the rupture of β-O-4 structure. Overall, the approach involves valorizing products derived from lignin biopolymer, providing the opportunity for the comprehensive utilization of all components within lignocellulose.

Lignocellulosic nanofibers (LCNF), blending nano-scale cellulose and lignin, were carboxylated and integrated with PVA and baicalin to create a molecularly imprinted membrane (CLCNF-MINM). This innovation, leveraging reactive deep eutectic solvent technology and electrospinning, boosts adsorption capacity by 12.3–21.5 % and resolution by 31.6 %, achieving a max capacity of 142.1 mg·g −1 . The high surface area, layered structure and tunable surface chemistry of carboxyl lignocellulose nanofibers (CLCNF), along with chemisorption and multimolecular adsorption mechanisms, significantly improve adsorption efficiency and selectivity. The membrane's mechanical strength is quadrupled and it retains 96.4 % of its absorption capacity after eight cycles of use. CLCNF-MINM significantly enhances the efficient utilization of biomass resources while exhibiting exceptional performance in the separation and purification of natural products. This study provides valuable insights into the development of advanced materials for improved natural product purification.

For building complexes in low-latitude regions, the efficient storage and conversion of high-intensity solar energy remain a significant challenge. Although building energy-efficient phase change materials (BEE-PCMs) offer a potential solution, their practical application is often limited by component leakage and poor material compatibility, which typically necessitate high packaging costs. In this work, a low-cost packaging strategy is proposed by physically entangling cross-linked phase change polymers (PCPs), lignocellulose (LE) and low density polyethylene (LDPE), resulting in a green modified PCP (MPCP). Among these, MPCP-6 with 6 wt% LE exhibits excellent mechanical properties, with a tensile strength of 3.9 MPa, compressive strength of 62.4 MPa, and toughness of 30.7 kJ/m 3 —equivalent to 487.5 %, 515.7 %, and 874.6 % of the unmodified PCPs, respectively. Furthermore, MPCP-6 possesses intrinsic anti-leakage capability and demonstrates remarkable thermally induced flexibility, achieving 720° curl deformation at 50 °C. Compared to commercial machine-made concrete blocks (CMB) and epoxy-enhanced PCM (EPCM) modules, MPCP-6 exhibits superior thermal responsiveness. The peak indoor temperature is reduced to 37.6 °C, which is 2.2 °C and 3.0 °C lower than that of EPCM and CMB modules, respectively. This work provides a promising strategy for improving thermal comfort in buildings located in low-latitude regions.

Transformation of accessible and renewable biomass resources into functionalized chemicals and polymer monomers has been one of the significant research fields in biorefinery. The key bottleneck is the lack of green technologies to synthesize those products traditionally manufactured from fossil feedstock. Herein, a sustainable route for the synthesis of naphthalenedicarboxylic acid derivatives has been developed via an integrated process consisting of Diels–Alder, dehydroaromatization, and hydrogenation with lignocellulose-derived dimethyl trans, trans-muconate and p-benzoquinone as raw reactants. The Lewis acid sites of Sn-Beta with porous structure promoted the efficient Diels–Alder reaction, and the excessive p-benzoquinone induced the dehydrogenation of the cycloadduct to dicarboxylate-substituted naphthoquinone. A hydrogenation reaction under mild conditions has been conducted to produce dimethyl 5,8-dihydroxynaphthalene-1,4-dicarboxylate, and the overall yield could reach 50% based on the input amount of muconate via the two-step process. This work has exploited a template method to prepare the naphthalene ring product with multiple oxygen-containing functional groups and might also inspire more design thoughts on synthesizing green aromatic monomers.

High product concentration in aerobic biorefining fermentation requires high lignocellulose feedstock loading. However, the high solids content and the consequent high viscosity of the lignocellulose hydrolysate severely limit oxygen transfer and thus lead to low aerobic fermentation rate. This study first investigates the experimental measurement and the computational fluid dynamics (CFD)-based simulation of oxygen transfer properties in the high solids loading and highly viscous lignocellulose hydrolysates. The oxygen mass transfer coefficients kLa values vary with various biorefining processing parameters. A minimum threshold kLa value was required for aerobic fermentation of glucose oxidation into gluconic acid. The rheological properties of the slurry were experimentally determined, and a CFD model was established for the design of aerobic fermentation bioreactors. The kLa values between the CFD calculation and the experimental determination were in good agreement for the high solids loading and highly viscous hydrolysate slurry. The study provided important information and useful tools for achieving efficient aerobic fermentations in high solids loading and highly viscous lignocellulose hydrolysates. The measured kLa value could be applied to general aerobic fermentation using lignocellulose feedstock.

Phosphoric acid-assisted pyrolysis (PAAP) is a pyrolysis technique with potential for the engineered and environmental application. Nevertheless, the volatilisation, immobilisation, and dissolution of phosphorus (P) species have been neglected during PAAP of lignocellulose. Therefore, we compared the transformation of P species with direct-pyrolysis and PAAP system, using multiple techniques including gas chromatography tandem mass spectrometry (GCMS) and 31 P nuclear magnetic resonance (NMR). It was also investigated that the properties of pyrogenic and modified carbons obtained from lignocellulose pyrolysis at 200–650 °C. As the temperature increased, volatile P species evolved into gas-phase during PAAP, inhibiting the formation of the macromolecular volatile components. Compared with pyrogenic carbons, modified carbons with more aromatic structures experienced a higher degree of dehydration and cyclisation via catalytic crosslinking reaction. PAAP system facilitated more generation of persistent free radical (PFR) below 500 °C and the attenuation of PFR signals was observed at 500–650 °C, which may be associated with the sequestration and elimination of P species between carbon matrix. Notably, three configurations of C 3 P O, C P O, and C O P were the major combinations of P and C elements on modified carbons. Increased gaseous P and decreased soluble P were observed with elevated temperatures in PAAP system. The species proportion of immobilised P clearly demonstrated the transformation of partial P species from inorganic to organic through pyrolysis. The immobilised P could serve as a potential sustained-release source participating in P biogeochemical cycles . These findings are fundamental for the technical design of lignocellulose pyrolysis.

Thermal insulation aerogel holds great promise in the transportation, storage, and use of temperature-sensitive electronic components under different environmental conditions. Due to their low density, high thermal stability, superior UV resistance, and low thermal conductivity , lignocellulose nanofibrils (LCNFs) aerogels meet the thermal insulation needs perfectly. However, the preparation of LCNFs aerogels with customizable size and high precision remains challenging. Herein, we report the following: (1) the preparation of LCNFs with tunable physicochemical properties from unbleached poplar pulp through the 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO)-mediated oxidation and ultrasonication approach, and (2) the 3D printing of customized thermal insulation materials using LCNFs as viscoelastic gelatinous inks. In addition to the chlorine-free bleaching merit, the LCNF inks exhibit much lower yield stress compared to cellulose nanofibrils (CNFs) inks, thereby facilitating the smooth extrusion of filament under a much lower printing pressure. Furthermore, the residual lignin endows LCNFs aerogels with superior moisture tolerance, mechanical protection, UV resistance, and thermal insulation performance for temperature sensitive electronic components such as chips and batteries . This work opens a promising avenue for the rapid manufacturing of customizable thermal insulation materials in a sustainable, cost-effective, and eco-friendly manner.

Lignin, as a main factor inhibiting the enzymatic hydrolysis of lignocellulose, was investigated by comparing lignin isolated from untreated and pretreated lignocellulose to elucidate the differences in the enzyme adsorption ability. The nonproductive adsorption of cellulase on lignin was investigated by using a quartz crystal microbalance with dissipation. The results indicated that more cellulase adsorbed on the lignin isolated from autohydrolysis and green liquor-pretreated lignocellulose than on protolignin. Higher temperature and enzyme concentration increased the initial adsorption rate and the amount of enzyme adsorbed on lignin. A dynamic equation for enzyme adsorption on lignin was established. The adsorption of enzymes on lignin increased as the content of phenolic hydroxyl groups, and β-β and β-5 linkages in the lignin increased, attributed to enhanced hydrogen bonding and hydrophobic interaction. Consequently, inhibition of the enzymatic hydrolysis of cellulose was promoted by a higher phenolic hydroxyl group, β-β, and β-5 content. The adsorption of the enzyme components on lignin followed the order: β-glucosidase > xylanase > endo -glucanase > cellobiohydrolase, as revealed by polyacrylamide gel electrophoresis analysis. Electrostatic interaction increased the adsorption of β-glucosidase and xylanase on lignin, while synergistic hydrophobic interaction and hydrogen bonding increased the adsorption of endo -glucanase and cellobiohydrolase on lignin. The results indicate that the adsorption of enzymes on lignin is affected by the structure of lignin and the composition of the enzymes. The findings of the current study provide fundamental knowledge for improving the enzymatic conversion of lignocellulose.

As a common renewable raw material , lignocellulose had the advantages of high carbon content and rich active groups, however its poor flame retardancy limited the application. In this paper, lignocellulose and zirconium oxide (ZrO 2 ) were employed as raw materials, nano-ZrO 2 -lignocellulose flame retardant composites (LCZ) were prepared by mechanical grinding and hot pressing. The friction between lignocellulose and nano-ZrO2 was increased by pretreatment using mechanical grinding. After hot-pressing, the ZrO 2 particles were attached on the lignocellulose. The results showed that LCZ composites had a better flame retardancy and mechanical strength . The mechanical strength of LCZ composite reached 34.9 MPa and improved by 31.2 % while the lignocellulose was 26.6 MPa. Owing to the existence of ZrO 2 , the heat release rate and total heat release rate of LCZ composite were reduced 61 % and 27 % than that of pure lignocellulose material (LC), respectively. The smoke production rate of LCZ composite decreased by 58 % compared with that of LC composite. Thermogravimetric studies showed that ZrO 2 could promoted the charring of lignocellulose, further formed a carbon protective layer on the lignocellulose surface. Therefore, it provided a better modified method for preparing flame retardant lignocellulose composite.

Paper-based materials from renewable lignocellulosic resources are promising for clean production systems but are often limited by insufficient mechanical strength and poor moisture resistance. Herein, a sustainable strategy is proposed to fabricate high-strength and low-permeability lignocellulose paper-based composites reinforced with lignin-containing lignocellulose nanofibrils (LCNFs). Micro–nano fibrils were prepared directly from unbleached poplar pulp without extensive chemical purification. With an optimized LCNF content of 10%, the resulting composite exhibited markedly improved mechanical properties, achieving a tensile index of 82 N·m/g and a burst strength of 390 kPa, along with substantially reduced water vapor transmission. The enhanced structural integrity improves dimensional stability under humid or aqueous conditions, contributing to prolonged service lifetime of paper-based materials in sustainable applications. In addition to structural reinforcement, the retained lignin enables sustainability-oriented functionalization. Lignin acted as an intrinsic reductant for the in situ immobilization of palladium nanoparticles without external reducing agents. These composites exhibited enhanced barrier properties and outstanding catalytic performance in the reduction of Cr(VI) to Cr(III), demonstrating their potential for environmental remediation applications. This work underscores the value of lignocellulose as a renewable, sustainable material for functional composites with broad environmental and energy-related applications, marking a promising route toward eco-friendly, high-performance polymer composites.
