Deciphered lignin-derived aromatic catabolism in Myceliophthora thermophila . • Mapping a convergent pathway converting H- and G-type aromatic monomers into 3,4-DHB. • Redirected metabolic flux to achieve up to 95.8% molar yield of 3,4-DHB. • Conversion of raw corncob into 3,4-DHB by the engineered strains. • Established a fungal platform for lignin valorization toward aromatic chemicals. Lignin accounts for up to one-third of plant biomass, making it the second most abundant biopolymer on Earth. The thermophilic ascomycete Myceliophthora thermophila is a well-established platform to produce chemicals from plant biomass. However, its capacity for lignin metabolism remains largely unexplored. This study demonstrates that M . thermophila can remodel lignin and metabolize a broad spectrum of lignin-derived aromatic monomers. By integrating transcriptomic profiling with targeted gene deletions, we mapped the key metabolic pathways for these aromatic compounds. Specifically, we found that M. thermophila funnels diverse p -hydroxyphenyl (H) and guaiacyl (G) aromatic monomers into the 3,4-dihydroxybenzoic acid (protocatechuic acid, 3,4-DHB) branch of the β-ketoadipate pathway. Disrupting the protocatechuate hydroxylase and 3,4-dioxygenase genes successfully redirected metabolic flux, achieving 42.5‒95.8% molar yields of 3,4-DHB from H- and G-type monomers. Notably, the engineered strains achieved direct 3,4-DHB production from raw corncob. These findings provide new insights into the metabolism of lignin-derived aromatic compounds in M. thermophila and establish a foundation for integrated lignocellulose biorefineries and aromatic bioprocessing.

Design and synthesis of heterostructured carbon nanofibers is significant for applications in the field of optoelectronics , conductors and catalytic devices. Although lignin has been widely used as building blocks for fabricating nanofibers , it is still very challenging to synthesize conducting heterostructured carbon nanofibers without using additional catalysts. Herein, we first in-situ grew graphene grafted carbon nanofibers (G/CNFs) using calcium lignin sulfonate as starting materials without addition of catalysts. Through the electrospinning, pyrolysis and washing procedure, the as-spun nanofibers are converted into the flexible G/CNFs films. The in-situ formed CaS nanoparticles serve as catalysts for the growth of graphene on the surface of the CNFs, when the carbonization temperature is over 1100 °C. The as-prepared G/CNFs films exhibit superior electronic conductivity of 2377.9 S m −1 , which is comparable to the values reported in the literature. As a proof-of-concept, the as-fabricated lithium-sulfur battery exhibits a high discharge of 808.7 mAh·g −1 after 600 cycles at 0.2 C by using the G/CNFs membrane as stand-alone and flexible sulfur cathode scaffolds. This work represents a promising new approach for designing heterostructured graphene/CNFs using low-cost lignin precursors, and provides significant insights for the sustainable development of CNFs in numerous applications.

Lignin nanoparticles (LNPs) address the challenges associated with the complex chemical structure and high molecular weight of lignin, thereby facilitating green value-added transformations. However, the heterogeneity of lignin significantly influences the self-assembly behavior of LNPs. To obtain lignin with optimal performance for the preparation of LNPs, a novel deep eutectic solvent (DES) featuring a robust hydrogen bond network (choline chloride/tartaric acid-FeCl3, CC/TA-FeCl3) was developed in this study. Extracted lignin exhibited a higher phenolic hydroxyl content and lower molecular weight. Specifically, the phenolic hydroxyl content (2.90 mmol g−1) increased by 15.54% compared to that extracted using (CC/lactic acid-FeCl3 (CC/LA-FeCl3)). Amphiphilic nanoparticles were synthesized via layer-by-layer self-assembly utilizing van der Waals forces and π–π interactions. They had a narrow particle size distribution (21–76 nm) and a small average particle size (35.33 nm). They exhibited a highly negative zeta potential of −31.25 mV and demonstrated effective free radical scavenging efficiency (79.87%). The water dispersion stability over 72 h was improved by 200%. The LNPs significantly enhanced the UV resistance (80%), tensile strength (72%), and hydrophobic characteristics (125%) of PVA films. LNPs/PVA film provides the feasibility for the high-quality development of green agriculture. These results provide a new approach for the green transformation of lignin through the preparation of efficient extraction and preparation of high-performance LNPs.

Titanium carbide (Ti 3 C 2 T x ) MXene combines exceptional conductivity, mechanical robustness, and multifunctionality, positioning it as a promising material for diverse applications. However, its industrial deployment remains hampered by the inability to precisely control redispersibility and oxidative stability. Herein, an interlayer chemical modulation strategy is reported, mediated by amphiphilic lignin-containing nanocellulose (LNC). Competitive interactions between the hydrophilic and hydrophobic segments of LNC within MXene interlayers enable precise tuning of spacing and interfacial chemistry. This approach allows rapid, industrial-scale spray drying to produce semi-solid MXene with long-term reversible redispersibility and outstanding oxidative stability. The resulting material can be fully redispersed into monolayer MXene even after 180 days of storage while maintaining high conductivity (≈7000 S cm −1 ). Moreover, by adjusting the post-drying time-dependent window, MXene powders can be programmably switched from a dynamically reversible to a permanently fixed structure, broadening their utility across multiple domains. This approach is expected to resolve the long-standing industry bottlenecks of MXene, including its susceptibility to oxidation, high transportation costs, and challenges in reprocessing, thereby opening a new path for the rapid transition of MXene from laboratory to commercial application.

The accelerating rise of atmospheric CO 2 remains a central driver of global climate change, highlighting the urgent need for scalable and energy‐efficient carbon capture technologies. Porous carbons are among the most promising solid adsorbents due to their high surface area, chemical stability, and tunable pore structures, which facilitate efficient CO 2 adsorption and low regeneration energy. Lignin is a renewable aromatic by‐product of the pulp and paper industry, which offers exceptional promise as a sustainable carbon source due to its abundance (50–70 Mt/year), high carbon content (>60 wt%), and rich aromatic structure. Unlike previous reviews broadly covering biomass‐derived carbons, this review focuses on recent advances in lignin‐derived porous carbons for CO 2 capture, correlating preparation strategies with structural evolution and adsorption performance. Chemical activation, templating, and hybrid methods enable precise control of ultramicropores (<0.7 nm), mesoporous channels, and heteroatom functionalities, which synergistically determine adsorption capacity, selectivity, and regeneration energy. Emerging approaches such as amine functionalization introduce strong chemisorption sites for post‐combustion and direct‐air capture, while AI‐assisted design accelerates understanding of synthesis–property–performance relationships. Despite remarkable progress, remaining challenges in feedstock variability, scalability, and greener process development are discussed along with future prospects for sustainable CO 2 capture using lignin‐derived porous carbons. Lignin‐derived porous carbons offer a sustainable and scalable route for high‐performance CO 2 capture. By tailoring ultramicroporosity, hierarchical pore networks, and heteroatom functionalities through chemical activation, templating, and hybrid methods, adsorption capacity and selectivity can be optimized. This review correlates. synthesis–structure–performance relationships to enable the rational design of scalable, energy‐efficient carbon capture materials for circular carbon technologies.

Herein, a novel indole-modified cross-linked lignin aerogel (INAALGA) was successfully designed and fabricated. The uranium(VI) extraction performance and mechanism of INAALGA were comprehensively investigated. The results demonstrate that INAALGA exhibits excellent extraction capabilities for uranium(VI), reaching equilibrium within 240 min, with kinetics well described by the pseudo-second-order model. At 298 K, the extraction capacity of INAALGA for uranium(VI) reached 694 mg g ‐ 1 , and it maintained a high extraction efficiency of over 83.3 % after three consecutive adsorption-desorption cycles. Practical validation using simulated uranium-containing wastewater confirmed that INAALGA is a highly promising material for uranium(VI) extraction and enrichment. The extraction process involves multiple mechanisms, including complexation, electrostatic interaction and cation-π interactions. In brief, INAALGA demonstrates considerable potential for uranium(VI) remediation and recovery from wastewater. Furthermore, this work not only presents an applicable approach to alleviate the increasingly serious energy crisis via recycling uranium from nuclear wastewater, but also enriches the method of synthesizing N-doped materials for uranium(VI) adsorption.

In this study, a self-healing lignin-based polyacrylamide/polyvinyl alcohol (SL-cPAM/PVA) hydrogel featuring excellent high temperature and salt resistance was successfully synthesized via a two-step method. Sodium lignosulfonate (S-Lignin) was first incorporated into a chemically crosslinked polyacrylamide (cPAM) network, followed by the formation of dynamic boronate ester linkages among polyvinyl alcohol (PVA), catechol groups, and borax to construct a dual crosslinked structure. The rheological, thermal, and mechanical properties of the hydrogel were comprehensively characterized. The results indicate that the introduction of S-Lignin improved the initial decomposition temperature from 150 °C to 178 °C, and enabled the hydrogel to achieve self-healing behavior at 130 °C, supported by reversible borate ester bonds, hydrogen bonding, and ionic interactions. The hydrogel maintained structural integrity in high-salinity environments (up to 21 × 10 4 mg/L) and demonstrated remarkable recovery in mechanical strength and microstructure after damage. Even after 30 days of thermal aging at 130 °C, brine-healed hydrogel remained intact without signs of hydrolysis. These findings indicate the excellent potential of SL-cPAM/PVA hydrogel as a water-plugging material in high-temperature, high-salinity oilfield environments, providing a sustainable and functional approach for enhanced oil recovery.

Conventional eutectic quasi-solid electrolytes (EQSEs), despite their intrinsic safety and sustainability, are fundamentally limited by the mechanical-conductivity trade-off, severely restricting practical deployment. Here, a lignin-engineered double-cross-linked EQSE is reported that overcomes these challenges through synergistic dual-dynamic networks: (1) an organic polyacrylamide/poly(acrylic acid) (PAM/PAA) framework establishing continuous ion-transport channels and (2) Fe3+-coordinated cross-links coupled with hydrogen bonding resolving the mechanical-conductivity trade-off. The resultant DES–LN–Fe3+ electrolyte simultaneously achieves a high ionic conductivity of 0.031 S cm–1 at 25 °C and exceptional ductility (851% strain). When deployed in flexible supercapacitors, it delivers a high specific capacitance of 310.6 F g–1 (0.1 A g–1) with exceptional low-temperature resilience (45.8% capacity retention at −40 °C) and cycling stability (95.7% after 10,000 cycles). Notably, the electrolyte doubles as a high-sensitivity strain sensor (gauge factor = 3.183), enabling real-time monitoring of biomechanical motions. This work establishes a dynamic dual-cross-linking paradigm to design multifunctional quasi-solid electrolytes for integrated energy storage and sensing platforms in extreme environments.

Lignin, as a green and environmentally sustainable natural material, is indispensable to be reasonably developed and utilized. Herein, lignin macromolecules are used as raw materials of polyhydroxyl structure to synthesize polyurethane macromolecules. It is found that the optimal mass ratio of lignin to isocyanate group in the synthesis of polyurethane is 95/5. The lignin-based polyurethane putted the lignin as a fulcrum to form a hydrogen bond with the polyurethane macromolecular chain to form a hydrogen bond network structure, so that its elastic recovery rate attains 94.7%. Meanwhile, its tensile strength and breaking elongation rate reach 16.2 MPa and 1049.5% respectively. Furthermore, the lignin-based polyurethane synthesized in this work still maintain excellent mechanical properties after thermal reprocessing. Moreover, the lignin-based polyurethanes prepared by this approach also possess excellent transparency and UV resistance, and the average ultraviolet protection factor (UPF)value of the lignin-based polyurethane hot-pressed fabrics obtained by hot pressing is greater than 50. This work provides an innovative and sustainable strategy for the further application of lignin, a pure natural material, as a bio-based multifunctional additive to packaging, textiles, automotive trim and other fields.

The traditional polyvinyl alcohol composite hydrogel exhibited poor swelling and mechanical properties, which limited its application. To solve these issues, we use biomass lignin as raw material, PVA as matrix template and epichlorohydrin as cross-linker to prepare the Lignin-PVA super-absorbent hydrogels with the swelling ratio of up to 456 g/g under mild condition. When the lignin concentration was increased from vacancy to 5%, the swelling ratio of the Lignin-PVA hydrogels was increased from 92 g/g to 456 g/g. The lignin-based hydrogel synthesized by the higher molecular weight PVA showed better swelling performance. Softwood lignin, hardwood lignin and corncob lignin could also be used to fabricate the Lignin-PVA super-absorbent hydrogels with the swelling ratio of higher than 500 g/g. However, the optimum amount varied from different lignin types, which was related to the molecular weight and phenolic hydroxyl content of lignin. The structural mechanism of the Lignin-PVA hydrogel was proposed to clearly certify the enhancing role of lignin. The adsorption capacity of the Lignin-PVA hydrogel with respect to rhodamine 6G, crystal violet and methylene blue dyes was up to 196, 169 and 179 mg/g, respectively. The Lignin-PVA hydrogel presents great potential applications in the fields of soil water retention and seed cultivation in agriculture, and dye pollutant removal.

It is still a great challenge to prepare lignin/polyolefin composites with good strength and toughness. Inspired by the energy sacrificial mechanism from biomaterials, dynamic hydrogen bonds (H-bonds) are incorporated into the lignin/ethylene-propylene-diene monomer (EPDM) composite system to improve the interfacial interactions between lignin and EPDM. Such H-bonding interactions are demonstrated to be able to simultaneously improve the modulus, strength, and toughness of lignin/EPDM composites without sacrificing the extensibility. This work provides a facile method for the high-valued utilization of lignin in the preparation of high-performance elastomer composites using bio-renewable resources as reinforcing agent.

With the gradual global standardization of carbon emission policies, the development of renewable resources to replace traditional fossil resources is assuming increasing importance. Lignin is the most abundant natural source of aromatic compounds and has the potential to replace petroleum-based aromatic hydrocarbons . In this work, the rigid benzene ring structure and excellent photothermal properties of lignin were exploited to produce light-driven lignin-based shape memory polymers (ELEPs) that contain high proportions of lignin and have good mechanical properties. Enzymatically hydrolyzed lignin (EL), epoxy soybean oil (ESO) and polyethylene glycol (PEG 400) were copolymerized and cured to form ELEPs, which have a disordered three-dimensional network. An increase in the proportion of EL from 40 to 60 wt% enhanced the mechanical properties, as reflected by an increase in tensile strength from 11.3 to 30.8 MPa and in the glass transition temperature (T g ) from 93 to 115.7 °C. Under simulated solar irradiation (2000 W m −2 ), ELEP50, which contains 50 wt% lignin and has a T g of 105 °C, reached a surface temperature as high as 105 °C and achieved shape memory within 20 s. The shape fixation ratio (R f ) and shape recovery ratio (R r ) were stably >98 % and >97 %, respectively, over eight cycles in a bending-recovery experiment. The unique light-driven shape memory properties of ELEPs provide a method for high value utilization of EL, and the design strategy offers new ideas for producing novel intelligent materials.
