A novel HACC/lignin composite film incorporating nisin was successfully fabricated. • Lignin incorporation endows the film with superior ultraviolet-blocking capability. • The addition of nisin significantly improves the mechanical and barrier properties. • Nisin confers potent and broad-spectrum antibacterial activity to the composite film. • The film effectively extends grape shelf life by antibacterial and anti-UV functions. A multifunctional composite packaging film integrating chitosan quaternary ammonium salt (HACC), lignin, and nisin was developed to achieve synergistic UV-blocking and antibacterial performance. Nisin, uniformly dispersed throughout the HACC/lignin matrix via hydrogen bonding, not only imparted potent antibacterial activity but also reinforced mechanical strength, thermal stability, and barrier performance. Of all formulations evaluated, HLN-0.4 delivered the most favorable combination of properties: a tensile strength of 5.99 MPa, an elongation at break of 141.21%, and effective antibacterial activity against Staphylococcus aureus , Bacillus subtilis , and Listeria monocytogenes . In grape preservation trials, HLN-0.4 extended postharvest shelf life to 15 days, curtailed weight loss from 17.9% to 9.0%, and sustained fruit firmness at 29.74 N, approximately 63% above the 18.28 N measured in unpackaged controls. Taken together, these findings position HLN-0.4 as an effective, sustainable, and scalable packaging solution with strong potential for extending postharvest shelf life and maintaining the quality of fresh produce.

Efficient seawater oxygen evolution requires electrocatalysts that combine high activity, chloride tolerance, and long-term durability. Herein, a phosphorus–lignin ligand strategy is developed to construct an activation-prone P-CoMoO 3 @PLC precatalyst. Phosphorylated lignin enables homogeneous Co/Mo coordination, lattice P incorporation, oxygen-vacancy generation, and conductive carbon confinement, producing a metastable CoMoO 3 lattice with perturbed Co-P-Mo/Co-O-Mo coordination environments. P-CoMoO 3 @PLC requires only 180 mV at 10 mA cm −2 in simulated seawater, and sustains 500 mA cm −2 in natural seawater, outperforming commercial RuO 2 in durability. Operando analyses reveal an activation-induced dissolution–reconstruction pathway, in which partial Mo/P leaching converts the precatalyst into a Co(OH) 2 -derived CoOOH-rich interface coupled with residual CoMoO 4 . Co(OH) 2 -like species serve as hydroxylated intermediates, whereas CoOOH-like sites constitute the active OER phase; residual CoMoO 4 and the lignin-derived carbon matrix stabilize the reconstructed layer and promote charge transport. DFT calculations further show favorable *OH formation but thermodynamically unfavorable *Cl adsorption, explaining the preferential OER pathway and suppressed chlorine-related reactions. This work establishes bio-ligand metastability and reconstruction-driven interface engineering as a robust design strategy for seawater electrolysis.

A massive global annual demand exists for elastomers applied in tires, seals, and shock absorbers. Against the backdrop of sustainable development, next-generation damping elastomers are expected to integrate multiple functionalities, notably high biobased content and recyclability. Nevertheless, the fabrication of such advanced elastomers remains fraught with challenges. This work designs and synthesizes pyridine-functionalized biobased elastomers (polar rubber matrix) using the biobased monomer diethyl itaconate in conjunction with partially petroleum-derived butadiene and 4-vinylpyridine via environmentally benign emulsion polymerization. Subsequently, damping elastomer composites (VPx-L-DIH) with a substantial bio‑based fraction are constructed by employing lignin as a biobased reinforcing filler and 1,6-diiodohexane (DIH) as a crosslinking agent. Due to the energy dissipation mechanism of the dynamic network (hydrogen bonds and Zn 2+ -based coordination bonds), VPx-L-DIH composites show excellent mechanical properties (tensile strength of 16.8 MPa) and a broad, adjustable damping temperature range (96.9 ° C, tan δ > 0.3). By virtue of the exchange reaction through C–N transalkylation in quaternized pyridine units, the VPx-L-DIH composites show good reprocessability. Furthermore, utilizing the photothermal effect of lignin, these materials exhibit significant photothermal responses under NIR irradiation. This work offers a viable sustainable approach for the structural design of damping elastomers and lignin-based multiple functional composites.

Lignin catalytic hydrogenolysis offers a promising route to yield aromatic and alkane fuels for sustainable aviation. However, its widespread application is hindered by the reliance on high-pressure hydrogen and aggregation of metal catalysts during hydrogenolysis processes. Self-transfer hydrogenolysis is an attractive method to depolymerize without exogenous hydrogen, but suffers from low catalytic activity and poor stability. In this study, a nickel catalyst confined on cerium dioxide (CeO 2 ) nanocrystals with oxygen vacancy (O V ) is reported for efficient hydrogenolysis of both native and technique lignin into aviation fuel precursor under a nitrogen atmosphere. The O V in CeO 2 acts as electron-deficient sites, promoting the reduction of neighboring Ni atoms to a lower valence state. These low-valent Ni species efficiently cleave C─O bonds in lignin, while the oxygen vacancies serve as anchoring sites to suppress aggregation of metallic Ni nanoparticles. The confined Ni/CeO 2 with oxygen vacancies exhibits top-level hydrogenolysis performance with an exceptional aromatic monomer yield of 42% from eucalyptus lignin and ≈20% from technical lignin, comparable to that of commercial noble metal catalysts. This work opens up new possibilities of designing efficient catalysts to depolymerize both raw wood powder and technical lignin toward aviation fuel precursor.

Traditional pesticide formulations exhibit low utilization rates due to poor foliar deposition and instability under UV irradiation during application, which limits their efficacy in enhancing agricultural productivity. This study developed a lignin-based nanocarrier system through solvent-antisolvent precipitation and coordination-driven self-assembly of lignin with Fe³ ⁺-tannic acid (TA) complexes to address these challenges. A nanoherbicide (called PMT@AFT) was prepared using prometryn (PMT) as a model drug. Different preparation conditions of the lignin-based nanocarrier system were systematically investigated to regulate the particle size of the microspheres, as well as the four main properties of the nanopesticide: stability, adhesion, slow-release, and efficacy, to assess its effect on non-target crops. The results showed that the chelating coordination of Fe³ ⁺-TA constructed a cross-linking stabilization layer on the surface of lignin microspheres and formed a typical core-shell structure. This endows it with excellent UV resistance, high blade adhesion performance, and good sustained-release performance, with a long duration of effect, releasing only about 60 % after 70 h. Furthermore, PMT@AFT demonstrated excellent herbicidal efficacy against barnyard grass while significantly reducing phytotoxicity to non-target crops. This study establishes a novel strategy for developing eco-friendly and safer nanopesticide formulations.

Regulating electron transfer through defect engineering to selectively catalyze the cleavage of lignin C–O bonds is of significant scientific importance for the directed conversion of biomass into high-value chemicals. However, the precise dissociation of chemical bonds remains challenging. In this study, a 2D nanoflower-like NiAl-MMO catalyst was successfully constructed via a hydrothermal in situ pyrolysis synergistic strategy. An Al doping strategy was employed to fabricate Ni and Al3+-Ov (Ov denotes oxygen vacancy) synergistic dual active centers in NiAl-MMO. The research results indicate that the introduction of Al significantly enhances the catalytic performance. When an appropriate amount of Al is doped, it not only effectively increases the specific surface area of the catalyst and optimizes its pore structure but also enables the formation of moderate-strength interactions between metallic Ni and Al. Meanwhile, the presence of Al induces an increase in the concentration of Ov in the catalyst. Ov can regulate the electronic state of Ni active sites by modulating electron density while also enhancing the Lewis acidity of the catalyst, thereby improving its adsorption capacity for reactants. This electronic regulation optimized the electronic coupling environment of bimetallic sites and significantly strengthened the synergistic effect between Al3+-Ov and Ni sites, improving the hydrogen activation capability and directed C–O bond cleavage performance of the catalytic system. The catalyst exhibited excellent C–O bond dissociation selectivity in the lignin hydrodeoxygenation (HDO) process with a total liquid yield of 45.7 wt % (68.4% selectivity for C6+ cyclohexanol), providing a new approach for the synthesis of aviation fuel precursors. This work offers a novel strategy for the directed conversion of lignin through the synergistic regulation of interfacial defects and electronic structures.

Effect of the molecular structure of lignin-based polyoxyethylene ether (EHL–PEG) on enzymatic hydrolysis of Avicel and corn stover was investigated. With the increase of PEG contents and molecular weight of EHL–PEG, glucose yield of corn stover increased. EHL–PEG enhanced enzymatic hydrolysis of corn stover significantly at buffer pH 4.8–5.5. Glucose yield of corn stover at 20% solid content increased from 32.8% to 63.8% by adding EHL–PEG, while that with PEG4600 was 54.2%. Effect of EHL–PEG on enzymatic hydrolysis kinetics of cellulose film was studied by quartz crystal microbalance with dissipation monitoring (QCM-D) and atomic force microscopy (AFM). An enhancing mechanism of EHL–PEG on enzymatic hydrolysis kinetics of cellulose was proposed. Cellulase aggregates dispersed by EHL–PEG excavated extensive cavities into the surface of cellulose film, making the film become more loose and exposed. After the maximum enzymatic hydrolysis rate, the film was mainly peeled off layer by layer until equilibrium.

Considering the health and safety effects of the active components in current sunscreens has inspired the enthusiasm for developing biocompatible alternatives, especially from nature. However, natural active ingredients have inherent drawbacks, such as dark-colored lignin and easily oxidized polyphenols, which are difficult to meet the requirements of smart sunscreens. Integrating two or more natural sunscreens in a single unit can overcome the shortcomings of a single active ingredients and synergistically enhance ultraviolet (UV) radiation protection. Herein, a composite microsphere (HCAS) was fabricated by incorporating dopamine modified lignin, silk fibroin, phenylboronic acid modified hyaluronic acid and chlorogenic acid through self-crosslinking of boric acid ester bonds and using genipin as assistant cross-linker. This multi-component coordination strategy imparts HCAS microspheres with superior UV protection performance and photostability under UV exposure. The remarkable properties of HCAS are evidenced by its high sun protection factor (SPF) of 55 when incorporated at 10% into a base cream, representing a significant improvement in color clarity compared to lignin-based formulations. Notably, HCAS exhibited exceptional antioxidant activity, capable of effectively eliminating reactive oxygen free radicals (DPPH•, OH• and O₂• − ). Furthermore, HCAS microspheres demonstrate excellent interfacial activity, functioning as an efficient Pickering stabilizer under various conditions. In vitro biological evaluations confirmed that HCAS not only has good biocompatibility but also shows the potential to promote cell growth. This study demonstrates that integration of multi-component natural ingredients for synergistically enhancing UV performances is an effective strategy for future sunscreens development.

Conventional epoxy asphalt is a thermosetting material that is difficult to reprocess and cannot be easily recycled after disposal. In this study, a lignin-based epoxy asphalt (ELEA) with thermoplastic and thermosetting properties was prepared by introducing a lignin-based vitrimer system, which has a dynamic, covalently bonded, cross-linked ester network, into the asphalt. The mechanical properties (tensile strength, 1.605 MPa; elongation at break, 382.38 %) also meet the requirements of epoxy asphalt for steel bridge deck pavement. The viscosity, thermal properties and high-temperature reversibility of ELEA show that ELEA has good operability, thermal stability and potential for recycling, in line with the trend towards the development of a circular economy. The use of biomass-based derivatives for the epoxy resin and curing agent in ELEA also reduces dependence on non-renewable petroleum resources and provides a useful reference for the high-value and efficient development and utilization of industrial lignin.

Graphical New antioxidants were prepared by oxidative depolymerization of lignin followed by aldol condensation to form conjugated structure with benzene ring. Kinetics of aldol condensation between lignin-derived aromatic aldehydes and methyl ethyl ketone was investigated. The increase in the antioxidation ability was confirmed by experimentation and interpreted by density functional theoretical calculation. Novel antioxidants are synthesized by CuSO 4 -catalyzed oxidative depolymerization of lignin to form aromatic aldehydes followed by aldol condensation with methyl ethyl ketone (MEK). Aldol condensation greatly improves the antioxidation ability of lignin depolymerized products. Three lignin monomeric aromatic aldehydes, – p -hydroxybenzaldehyde, vanillin, and syringaldehyde – are further employed for aldol condensation with MEK, resulting in successful synthesis of new antioxidants 1-(4-hydroxyphenyl)pent-1-en-3-one (HPPEO), 1-(4-hydroxy-3-methoxyphenyl)pent-1-en-3-one (HMPPEO), and 1-(4-hydroxy-3,5-dimethoxyphenyl)pent-1-en-3-one (HDMPPEO), respectively. Kinetic modeling illustrates that p -hydroxybenzaldehyde has the highest rate of reaction with MEK, followed by vanillin and then syringaldehyde, which is probably affected by the presence of methoxy groups. The syringaldehyde-derived product (HDMPPEO) displays the best antioxidation ability. As revealed by density functional theory calculations, electron-donating groups, such as methoxy, and conjugated side chains effectively improve the antioxidation ability. A hydrogen atom transfer (HAT) mechanism tends to occur in nonpolar solvents, whereas a sequential proton-loss electron transfer (SPLET) mechanism is favored in polar solvents. This work thus can inspire new pathways for valorization of lignin to produce high value-added products.

Pre-hydrolysis liquor (PHL) of the dissolved pulp production process contains sugar and lignin is paper-making wastewater. Although sugar has the potential for value-added applications, the presence of lignin is problematic for the utilization of PHL. To improve the removal of lignin and maintain a high concentration of sugars in PHL, a novel process was introduced that included a dilute acid treatment, activated carbon (AC), and resin treatment of PHL, respectively. The results confirmed that most of the colloidal lignin and part of dissolved lignin were removed by dilute acid post-hydrolysis and the bonds of lignin-carbohydrate complexes were broken, and the adsorption efficiency of AC and resin was improved. In addition, the research found that high temperature can improve the adsorption efficiency of lignin on AC. In the case of without using PAC, the dilute acid treatment can reduce the dosage of AC from 25 g/L to 12.5 g/L and improve the flow rate of PHL through the resin from 0.1 mL/s to 0.8 mL/s in removing lignin to 90 %, while maintaining sugars in PHL. Also, the particle size of the PHL was significantly reduced by dilute acid-post hydrolysis which is probably because of the broken of β-O-4 aryl ether bond of lignin in PHL indicated by the analysis of 2D-HSQC. This work provides a practical technical process for industrial application of PHL and production of sugar solutions (mainly xylose) with high purity.

In this study, we present an innovative environmental silicon-, phosphorus-, and nitrogen-triple lignin-based flame retardant (Lig-K-DOPO). Lig-K-DOPO was successfully prepared by condensation of lignin with flame retardant intermediate DOPO-KH550 synthesized via Atherton–Todd reaction between 9, 10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO) and γ-aminopropyl triethoxysilane (KH550A). The presence of silicon, phosphate, and nitrogen groups was characterized by FTIR, XPS, and 31P NMR spectroscopy. Lig-K-DOPO exhibited advanced thermal stability compared with pristine lignin supported by TGA analysis. The curing characteristic measurement showed that addition of Lig-K-DOPO promoted the curing rate and crosslink density to styrene butadiene rubber (SBR). Moreover, the cone calorimetry results indicated Lig-K-DOPO conferred impressive flame retardancy and smoke suppression. The addition of 20 phr Lig-K-DOPO reduced SBR blends 19.1% peak heat release rate (PHRR), 13.2% total heat release (THR), 53.2% smoke production rate (SPR), and 45.7% peak smoke production rate (PSPR). This strategy provides insights into multifunctional additives and greatly extends the comprehensive utilization of industrial lignin.
