In this work, lignin-decorated ZnO composite was prepared via an in situ synthesis method using industrial alkali lignin (AL). First, the AL was modified by quaternization to prepare quaternized alkali lignin (QAL). The microstructure and optical properties of the QAL/ZnO composite were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), and UV–vis and photoluminescence (PL) spectroscopy. These results showed that the prepared QAL/ZnO composite possessed a flowerlike structure and showed excellent synergistic UV-absorbent properties. Interestingly, the anti-UV performance and mechanical properties of polyurethane (PU) were significantly improved when it was blended with the resulting QAL/ZnO. In comparison with pure PU film, the UV transmittance of the PU film was rapidly reduced. Furthermore, the tensile strength and elongation at break of PU film blended with QAL/ZnO were significantly improved, which was due to good compatibility between QAL/ZnO and PU matrix. Results of this work provide a significant and practical approach for the high value-added utilization of lignin as a functional material.

Membrane technology for wastewater remediation has aroused wide interest owing to its unique properties and potential applications. However, it remains challenging to explore green, efficient and robust membrane material and technique for complex wastewater treatment. Herein, we proposed using a simple electrospinning and in situ seeding method to fabricate a lignin-based electrospun nanofiber membrane (LENM) decorated with photo-Fenton Ag@MIL-100(Fe) heterojunctions for efficient separation of oil/water emulsions and degradation of organic dye. Thanks to the embedded lignin in LENM, an ultrahigh MIL-100(Fe) loading (53 wt %) with good wettability and high porosity was obtained. As a result, the hybrid Ag@MIL-100(Fe)/LENM exhibited excellent oil/water emulsions separation efficiency (more than 97%) without a compromise of water flux. Moreover, the hybrid membrane showed an excellent dye removal with degradation of 99% methylene blue within 30 min under illumination, which is attributed to a synergy of dye adsorption/enrichment and photo-Fenton catalytic degradation from Ag@MIL-100(Fe). Therefore, the lignin-based photo-Fenton hybrid membrane can lay the foundation for the preparation and application of green, sustainable and versatile membrane materials and technologies for efficient complex wastewater remediation.

As the traditional anode material of lithium-ion batteries, tin dioxide (SnO 2 ) has the characteristics of a high theoretical capacity and stable crystal structure. However, the alloying/de-alloying reaction between tin and lithium ions causes volume expansion and continuously generates an SEI film, which causes the electrode to fall off the current collector and the capacity fade rapidly. Generally, a composite of carbon materials and SnO 2 can alleviate the expansion and pulverization phenomena. However, the microstructure of carbon materials is complex and changeable, which makes it difficult to definitively state the influence mechanism of the microstructure on the lithium storage performance of composite materials. Here, three kinds of lignin-based porous carbons (LPCs) with different microstructural characteristics, along with a high graphitization, high specific surface area and hierarchical porosity, are obtained by regulating the process of gas exfoliation and in situ activation. Furthermore, a series of LPC/SnO 2 composites are obtained by an ultrasonic dispersion and ball milling method. Electrochemical property results show that the hierarchical porous LPCs are more conducive to the dispersion/coating of SnO 2 nanoparticles and that the reversible specific capacity of the electrode material increases from 64 to 620 mA h g −1 , effectively mitigating the expansion and pulverization of SnO 2 during the lithium storage process.

Lignin has been widely used as a high-quality carbon source in the preparation of carbon electrodes. Because the skeleton of lignin molecules is an unordered three-dimensional network structure, it is difficult to obtain high-performance porous carbon electrode materials with regular structures by conventional carbonization methods. To improve the electrochemical performance of lignin-based carbon, green, convenient and mass-produced lignin-based porous hollow carbon shell frameworks (HCSFs) were proposed. With the help of electrostatic forces, lignin/silica nanocomposites were generated by an insitu self-assembly and coprecipitation method using quaternary ammonium lignin and sodium silicate as raw materials. After carbonization and activation, HCSFs with hollow porous frame structures rich in nitrogen were obtained. The prepared HCSFs can maintain a reversible specific capacity of 480 mA h g −1 after 200 cycles at 200 mA g −1 as a lithium-ion battery anode, and they can also maintain a specific capacity of 180.4 mF g −1 after 10,000 cycles at 1 A g −1 as a supercapacitor electrode. Their better energy storage performance is mainly attributed to the special hollow shell structure of HCSFs, which can provide channels for rapid ion transport, and the doping of nitrogen atoms can also provide an increase in the number of storage sites. This work provides a theoretical basis for the preparation of carbon shells from biomass and widens the application field for the high value utilization of industrial lignin.

TtHSF2β-I regulates lignin transformation across multiple substrate levels. • Multi-scale framework links natural biomass to defined lignin systems. • TtHSF2β-I may relieve TtHSF2a-mediated repression by interfering with oligomerization. • TtHSF2β-I improves aromatic compound transformation and utilization. White-rot fungi are the primary biological decomposers of lignocellulosic biomass owing to their powerful lignin-modifying enzyme (LMEs) system. Here, we analyzed the regulatory role of TtHSF2β-I, an alternatively spliced variant of heat shock transcription factor (HSF) in Trametes trogii S0301, at three levels of substrate complexity: native poplar wood, synthetic lignocellulosic media, and specific lignin-derived monomers. Overexpression of TtHSF2β-I resulted in extensive disruption of poplar wood lignocellulose, whereas its deletion impaired fungal growth and substrate degradation. Transcriptomic analysis revealed that overexpression of TtHSF2β-I enhanced the expression of numerous genes encoding key lignocellulose-degrading enzymes. Using synthetic lignocellulose media and specific lignin-derived compounds, we further demonstrated that TtHSF2β-I controls the degradation and transformation of lignin-related compounds. Structural modeling and protein interaction assays suggested that TtHSF2β-I lacks direct DNA-binding activity, in contrast to TtHSF2α. Instead, it modulates transcription via protein–protein interactions, possibly interfering with TtHSF2α oligomerization to de-repress ligninolytic genes. In summary, our results indicate that alternative splicing plays a significant role in regulating ligninolysis in fungi. TtHSF2β-I, in particular, could be a useful target for engineering fungi with improved efficiency in biomass conversion or bioremediation.

In this study, an amorphous carbon-rich carbon nitride photocatalyst was prepared by nitric acid treatment of pyrolyzed melamine followed by nitrogen annealing. The resulting semiconductor material exhibited an up-shifted valence band that enhances the oxidizing power of photogenerated holes, enabling selective C α −C β bond cleavage of 2-phenoxy-1-phenylethanol (2-POE). Using 1.5 g L −1 of the optimized photocatalyst in acetonitrile, 2-POE underwent first-order conversion with a reaction rate of 2.55 h −1 under a 9 W blue LED light source. Product analysis showed the formation of benzaldehyde as the major product, confirming C−C bond scission with 93.1% selectivity. In addition, ring-opening reactions were observed, producing fumaric and maleic acids as the by-products. Photocatalytic depolymerization of organosolv lignin further demonstrated ring opening of the β-O-4 linking motifs, forming dicarboxylic acids analogous to those generated from 2-POE. These demonstrate a metal-free photocatalytic platform capable of promoting β-O-4 bond cleavage in lignin model compounds and inducing photocatalytic structural modification of organosolv lignin, accompanied by the formation of low-molecular-weight aliphatic dicarboxylic acids.

Sodium-ion batteries (SIBs) represent promising alternatives to lithium-ion batteries for grid-scale energy storage owing to abundant sodium reserves. Nevertheless, the large ionic radius of Na + results in sluggish ion diffusion and poor sodium compatibility with graphite, which hinders the development of high-performance SIB anode materials. In this work, N, P co-doped soft-hard carbon nanofiber (PLCFP) are fabricated through electrospinning and subsequent pyrolysis. After systematic carbonization temperature optimization, PLCFP-700 treated at 700 °C delivers a reversible capacity of 339.5 mAh g −1 after 100 cycles at 25 mA g −1 and 224.3 mAh g −1 over 1000 cycles at 500 mA g −1 with outstanding cycling durability. The enhanced electrochemical performance originates from multiple synergistic advantages. N/P co-doping introduces structural defects and widens carbon interlayer spacing to 0.387 nm to facilitate Na + adsorption and intercalation. The one-dimensional nanofiber network accelerates electron transfer and shortens sodium ion diffusion paths. Additionally, the hybrid soft-hard carbon structure suppresses excessive graphitization of petroleum coke and optimizes carbon microcrystalline textures. This study offers a resource-efficient strategy to realize high-value utilization of petroleum coke industrial byproducts and lignin biomass waste, and provides a novel structural design concept for carbon-based anodes in high-performance SIBs.

Hydrogel is a kind of polymer material with water absorption performance, which can absorb and fix a large amount of water. Such materials are usually composed of cross-linked polymers whose cross-linked structure can form a three-dimensional network that allows water molecules to be absorbed and stored. After a variety of preparation processes, lignin hydrogel microspheres have played an important role in improving soil quality, promoting plant growth and improving environmental quality, and have broad market prospects. The hydrogel prepared by sodium alginate and lignin has excellent performance, mild reaction conditions, and can effectively avoid the deactivation of active substances. In this study, sodium alginate extracted from kelp and lignin extracted from wheat straw were innovatively used to prepare hydrogels. The results of thermogravimetric analysis (TG), Fourier transform infrared spectroscopy (FTIR) and nuclear magnetic resonance (NMR) confirmed the successful extraction of sodium alginate and lignin. Lignin@SA-PVA (SPL)microspheres were prepared by dropping method, and the expansion rate was 302.58 g/g. In this study, lignin hydrogel microspheres were applied to wheat seed germination experiments to verify its promoting effect on wheat seed germination and growth, which provided new ideas for the development of new hydrogel microsphere materials and laid a theoretical foundation for the popularization and application of such materials in the field of agriculture.

Natural fiber reinforced polylactic acid (NF/PLA) composites are attractive sustainable materials, yet their broader engineering use is limited by weak interphase load transfer and rapid, dripping combustion. A lignin migration driven interphase phosphorylation strategy was proposed to construct a continuous phosphate-rich interphase on reed fibers, enabling simultaneous reinforcement and flame retardancy in PLA. A mild and efficient solvent activation step induces in- situ lignin deposition and generates a reactive, adhesive fiber surface, followed by aqueous phosphorylation to covalently introduce phosphate functionalities. Crucially, this strategy preserves the intrinsic structural integrity of the macroscopic fibers while simultaneously tailoring the interface for enhanced adhesion and flame retardancy. As a result, the reconstructed interphase strengthens fiber matrix adhesion and promotes condensed phase charring while improving melt resistance to dripping. At a 30 wt% modified fiber loading, the composite reaches a limiting oxygen index of 33.0% and achieves a UL-94 V-0 rating with no cotton ignition. Cone calorimetry shows 38% and 27% reductions in peak heat release rate and total heat release relative to neat PLA. Meanwhile, tensile strength increases by about 15% and notched impact toughness by about 270%, evidencing effective load transfer. The lignin enriched, phosphate functionalized interphase synchronizes rapid melt stabilization with the formation of a compact protective char, thereby reconciling reinforcement with fire safety. This scalable interphase-engineering strategy offers a sustainable route to high performance PLA composites for transportation, electronics, packaging, and related applications.

ETA/SW pretreatment fractionated reed into fermentable sugars and N-containing lignin. • Achieved 82.20% lignin removal under optimized pretreatment conditions • Glucose and xylose hydrolysis efficiencies reached 84.72% and 66.70%, respectively. Exploring low-cost, low-energy-consumption methods to efficiently disassemble waste biomass and achieve full utilization of multi-components in lignocellulose has always been a significant challenge in the field of biomass pretreatment. In this study, a new strategy of high-solids inorganic salt-driven seawater/ethanolamine pretreatment was proposed. During pretreatment, inorganic salt ions in seawater induce cell wall swelling, which enhances the diffusion of ethanolamine into the fiber matrix. Acting as a basic nucleophile, ethanolamine promotes lignin depolymerization while simultaneously enabling amination modification. This process effectively suppresses lignin condensation and redeposition, resulting in improved cellulose preservation. Consequently, the treated biomass exhibits enhanced cellulose accessibility and significantly improved enzymatic hydrolysis efficiency. Under the favorable conditions, the glucan retention rate and lignin removal rate reached 94.29% and 82.20% respectively. Subsequent hydrolysis with cellulase (25 FPU/g) and hemicellulase (120 IU/g) gave glucose and xylose hydrolysis efficiencies of 84.72% and 66.70%, respectively. This strategy enabled the concurrent production of fermentable sugars and N-containing lignin. Moreover, the idea of using seawater instead of freshwater to pre-treat waste biomass and realize the productization of all components provides a promising route for the advancement of biomass pretreatment technologies.

Suppressing lignin condensation is crucial for the efficient deconstruction and utilization of lignocelluloses. However, the distinct stabilization behaviors of macromolecular lignin framework and low-molecular-weight lignin fragments remain unclear. How nucleophiles affect residual lignin–cellulase nonproductive adsorption has not been clearly elucidated. In this work, a cysteine-assisted formic acid (FA–Cys) pretreatment was used to separate lignin and improve the saccharification performance of bamboo biomass. Cysteine acted as a sulfur-based nucleophile to intercept reactive benzylic carbocations within the macromolecular lignin framework and aldehyde intermediates generated from β–O–4 cleavage of low-molecular-weight lignin fragments, thereby suppressing lignin condensation. The β–O–4 retention of recovered lignin increased from 25.9% to 89.6%, and the condensed structure decreased from 12.5 to nearly zero per 100 aromatic units. Cysteine decreased the maximum cellulase adsorption capacity of residual lignin from 10.5 to 4.5 mg/g, while excessive cysteine addition increased the adsorption capacity. High lignin removal (92.6%) and mitigated nonproductive adsorption of residual lignin resulted in an increase in glucose yield of FA–Cys-pretreated bamboo from 58.7% to 98.9%. This study advances the understanding of how nucleophiles suppress lignin condensation, providing a theoretical basis for the efficient separation of noncondensed lignin and enhanced cellulose saccharification of bamboo.
