In this study, two counterexamples of lignin preoxidation-hydroconversion were reported. First, two lignin feedstocks were preoxidized with 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) in acetonitrile with various dosages (15%, 30%, and 60%). Then, these preoxidized lignins (HELOs and MWLOs) were hydroconverted in supercritical ethanol catalyzed by Cu/CuMgAlO x . Total yields from HELOs were all higher than those from HEL , indicating the good promotion of DDQ preoxidation on the subsequent hydroconversion of HELOs, especially with the DDQ dosage of 15%. Differently, the promotion effect of DDQ preoxidation on the hydroconversion of MWLOs depended on the DDQ dosage as well as the reaction time. Through the comparison of two counterexamples, this work bursted the myth that preoxidation can always promote the subsequent hydroconversion of lignin, revealed the influence of lignin property, preoxidation degree, and reaction conditions on the subsequent hydroconversion of preoxidized lignin, and presented the new insight into the preoxidation-hydroconversion strategy for lignin.

At present, using biomass materials to modify graphene oxide (GO) to enhance the anticorrosion performance of coatings meets the requirements of future sustainable development. In order to endow lignin/GO coatings with self-healing function to reduce maintenance costs and avoid accidents caused by material corrosion failure, this work utilized electrostatic interactions to load zinc ions onto lignin/GO (Zn@LGO). Experimental results indicated that the cured coating exhibited both self-healing anticorrosion and photothermal conversion properties. When the content of Zn@LGO was 0.4 wt%, the surface temperature of the cured coating rose to 139.2 °C after 180 s of near-infrared radiation. The cured coating was left for 100 days in salt water, the Z0.01Hz value of coating VER-3 was up to 1.3 × 109 Ω cm2, which was two orders of magnitude higher than that of pure resin coating, and fewer corrosion products were observed on the metal surface. The scratch test showed that the damaged coating was soaked in 3.5 wt% sodium chloride for 72 h; the charge transfer impedance of coating VER-3 was 2.61 × 104 Ω cm2, which was one order of magnitude higher than that of pure resin coating. This was mainly because during metal corrosion, the hydroxide generated by the combination of hydroxide ions at the cathode and zinc ions covered the damaged area of cured coating, hindering the penetration of the corrosive medium. All in all, this research promoted the application of lignin, and also provided a reference for the design of composite coatings with both photothermal conversion and self-healing anticorrosion properties.

Eco-friendly, renewable and green biomass materials are considered as the superior carbon precursors for producing carbon quantum dots (CQDs) in large scale. A major challenge is the limited contents of fluorophores in biomass, which then results in low quantum yields (QYs) and inferior fluorescence emission ability of the obtained CQDs. Herein, lignin with amounts of unsaturated aromatic and carbonyl fluorophores was employed as the carbon precursors to prepare CQDs through a green, facile approach. The magnesium and nitrogen elements were successfully introduced into CQDs with the aim of enhancing their QYs and extending their emission wavelengths. The prepared magnesium, nitrogen-doped CQDs (Mg, N-CQDs) could emit green fluorescence with a quantum yield (QYs) up to 46.38 %. The mechanism of their fluorescence ability was discussed extensively. More interestingly, the Mg, N-CQDs displayed a fluorescence transition between green and yellow color at pH value of 5.4, indicating their potential application as a probe to detect pH values of complicated environments. The findings in this paper would provide a viable strategy to converse lignin biomass waste into high-quality fluorescence nanomaterials.

Supercapacitors, known for their long cycle life and high-power density, are pivotal in various industrial and everyday applications. Addressing the dual challenges of green chemistry and the high-value utilization of lignin, this study introduces a novel synthesis process of carbon aerogels. These aerogels incorporate temperature-responsive carbon nanotubes (CNTs), synthesized via a one-pot method using magnesium lignosulfonate as precursor. Notably, the optimized carbon aerogel (AC-600) demonstrates a specific capacitance of 369 F g −1 at a current density of 1 A g −1 and retains 100 % capacitance after 20,000 charge/discharge cycles at 10 A g −1 . It also achieves an energy density of 17.6 Wh kg −1 and a power density of 489.9 W kg −1 . This paper proposes a novel strategy of replacing randomly dispersed carbon nanoparticles with self-synthesized, temperature-responsive CNTs, enhancing the structural integrity of honeycomb lignin-based carbon aerogels. This innovative approach opens new avenues for the efficient use of lignin-based aerogels in energy storage technologies.

Bamboo, as a natural and sustainable biomass materials has garnered significant attention due to its wide distribution, rapid growth, and considerable economic value. However, bamboo is composed of fibers (F) and parenchyma (P) cells with different anatomical structures and chemical compositions, which present challenges for efficient deconstruction and high-value conversion. Herein, we used microwave-assisted maleic acid (MA) treatment to effectively deconstruct the main components of different bamboo tissues (bamboo powder, F and P), further achieved the preparation of lignin-containing cellulose nanofibrils (LCNFs)-based separators and lignin-based electrode materials. Then, their differences in physicochemical properties and application performance were comprehensively analyzed and compared. The results showed that the prepared LCNFs separators exhibited excellent mechanical strength and stable thermal properties. Specially, the LCNFs separator prepared from bamboo powder (B-LCNF-S) had the highest diameter size (15.7 ± 1.8 nm), porosity (69 %), and electrolyte absorption rate (296 %), which effectively promoted the ion transport. In addition, the lignin-based carbon materials derived from F exhibited the highest specific surface area (1373.31 m 2 g −1 ) and total pore volume (0.99 cm 3 g −1 ), and specific capacity. Finally, LCNFs separators and the corresponding lignin-based electrodes were further assembled into symmetrical supercapacitors, which showed significant differences in electrochemical performance. This study provides valuable insights into the efficient deconstruction and targeted conversion of different bamboo tissues, offering a pathway to harness bamboo's unique structural and chemical properties for advanced energy storage applications.

In light of the depletion of petrochemical resources and increase in environmental pollution, there has been a significant focus on utilizing natural biomass, specifically lignin, to develop sustainable and functional materials . This research presents the development of a lignin-based polyurethane (DLPU) with photothermal-responsiveness by incorporating lignin and oxime-carbamate bonds into polyurethane network. The abundant hydrogen bonds between lignin and the polyurethane matrix, along with its cross-linked structure, contribute to DLPU's excellent mechanical strength (30.2 MPa) and toughness (118.7 MJ·m −3 ). Moreover, the excellent photothermal conversion ability of DLPU (54.4 %) activates dynamic reversible behavior of oxime-carbamate bonds and hydrogen bonds, thereby endowing DLPU with exceptional self-healing performance. After 15 min of near-infrared irradiation, DLPU achieves self-healing efficiencies of 96.0 % for tensile strength and 96.3 % for elongation at break. Additionally, DLPU exhibits photocontrolled solid-state plasticity as well as an excellent phototriggered shape-memory effect (70 s), with shape fixity and recovery ratios reaching 98.8 % and 95.3 %, respectively. By exploiting the spatial controllability and photothermal-responsiveness of DLPU, we demonstrate multi-dimensional responsive materials with self-healing and shape-shifting properties. This work not only promotes the development of multi-functional polyurethanes but also provides a pathway for the high-value utilization of lignin.

Lignin-based porous carbon, a derivative of lignin, is acknowledged for its cost-effectiveness, stability, and environmental sustainability. It exhibits significant adsorption capacity for the removal of heavy metals and in wastewater treatment, rendering it a highly esteemed adsorbent material. However, the potential of lignin-derived porous carbon for the capture of iodine in environmental contexts has yet to be thoroughly investigated. This research aims to examine the iodine capture capabilities of lignin-derived porous carbon in both iodine vapor and iodine/cyclohexane solution. Initially, lignin derivatives (ADL) (Mn = 2.85 × 10 4 , Mw / Mn = 1. 73) were synthesized through the graft copolymerization of lignin (Mn ≈ 2500), 4-acetoxystyrene, and dienopropyl terephthalate in ethylene glycol, utilizing azobisisobutyronitrile (AIBN) as the initiator. Subsequently, ADL was transformed into layered lignin-based porous carbon (ADLC) by one-step carbonization and zinc chloride activation. The iodine adsorption capacity of ADLC was determined to be 2340 mg/g in an iodine vapor environment and 354 mg/g in a 500 mg/L iodine/cyclohexane solution. These findings indicate that the layered porous carbon (ADLC) derived from lignin represents a promising material for iodine capture, providing an economical, stable, and environmentally friendly approach to nuclear waste management.

Despite potential of layered double hydroxides (LDHs) in photocatalytic wastewater treatment was demonstrated, their practical applications remain constrained by inherent limitations including sluggish charge separation kinetics and insufficient stability. To overcome these critical challenges, we engineered a boron-doped porous lignin carbon loaded with copper-iron layered double hydroxides (B-PLC/CuFe LDH) photocatalyst through hydrothermal synthesis. The dual-modification strategy overcomes inherent limitations of conventional LDH systems through boron-induced electronic coupling and interfacial engineering. Boron doping modulates the electronic structure of the porous lignin carbon (PLC), strengthening interfacial interactions with CuFe LDH layers, while the hierarchical carbon framework enhances LDH dispersion and charge transfer efficiency. Systematic characterization (UV-DRS, Mott-Schottky) revealed that boron doping synergistically widened the composite's bandgap from 1.54 eV (pristine PLC) to 1.83 eV (B-PLC-3/CuFe LDH), while maintaining strong visible-light harvesting. According to Electrochemical impedance spectroscopy (EIS), boron doping reduced electrochemical impedance, and increased photogenerated radical formation (·O 2 - and ·OH), collectively enabling efficient arsenic pollutant degradation. The optimized B-PLC-3/CuFe LDH achieved 84.7% roxarsone (ROX) degradation within 60 min under visible light, outperforming pristine PLC by 2.05 times. This work establishes a new paradigm for overcoming LDH's intrinsic limitations through defect-engineered carbon hybridization, opening avenues for sustainable heavy metal remediation.

Local electric fields of the electrocatalysts can modulate adsorbate binding energies based on their polarizability and dipole moment, which directly influence the catalytic performance. Nevertheless, implementing the prevailing strategy remains challenging due to the scarcity of active sites and sluggish catalytic kinetics. Herein, a continuous heterogeneous-curvature nanoreactor (HeterC-LCS) is created to enhance local electric fields by optimizing the uniform-nanocurvature with tip effects. The H + concentration and H 2 O transmission rate of HeterC-LCS are improved by about 2.1 and 1.7 times that of the homogeneous curvature structure (HomoC-LCS) during the hydrogen evolution reaction (HER) process. Besides, HeterC-LCS demonstrates a rapid kinetics of intermediate transformation and an extremely low energy barrier. Such HeterC-LCS depicts a lowest overpotential of 9.2 mV at 10 mA cm −2 , which outperforms all known carbon- and Ru-based electrocatalysts. And the mass activity is approximately 60 times that of commercial Pt/C. This work proposes a novel strategy of uniform-nanocurvature optimized by tip effects toward industrially electrocatalytic HER.

Lignin, a major component of plant cell walls, is the most abundant source of natural aromatic polymers. Efficient production of its valuable degradation products requires highly selective catalysts. This study introduces a spin-state-modulated nanozyme system for precise lignin depolymerization into targeted biobased chemicals. Precise copper spin state control in two-dimensional (2D) copper-based metal organic framework (MOF) nanozymes, achieved via redox treatment and ligand exchange modulation, replicates natural laccase multicopper center spin synergy. Integrated experiments and theory reveal a volcano-shaped spin state-activity correlation, enabling synthesis of optimized nanozyme Cu(OH) 2 BDC-LA-OAc (COHBLO). This material demonstrates exceptional laccase-mimicking activity, with a peak reaction rate 70 times higher than natural laccase and a 5.14-fold specific activity increase. Through laccase-like catalysis, it selectively cleaves lignin β-O-4 linkages, directionally yielding fragments rich in phenolic hydroxyl groups. Their efficient reaction with epoxy groups produces a nanolignin-based epoxy adhesive. Featuring a three-dimensional cross-linked network, this adhesive delivers superior bonding under varied conditions. Its shear strength significantly surpasses commercial phenolic resins while eliminating conventional adhesive formaldehyde emissions. This study advances 2D MOF nanozyme design and establishes an integrated pathway from controlled lignin depolymerization to high-performance adhesive production, providing key theoretical and practical foundations for biomass valorization and sustainable adhesive development.

Development on sustainable and inexpensive polymer fibers with high mechanical and water resistance properties has garnered significant attention in infrastructure application. Herein, lignin nanoparticles (LNP) were used as a modifier, boron nitride nanosheets (BNNS)@hyperbranched polylysine (HBPL) obtained were regarded as the cooperative modifier, and then polyvinyl alcohol (PVA)/LNP/BNNS@HBPL composite fibers were fabricated successfully by wet and dry spinning. Vast free hydrophilic hydroxyl groups in PVA decreased due to hydrogen bonding interactions among LNP, BNNS@HBPL, and PVA, thereby attenuating intramolecular and intermolecular hydrogen bonding within PVA. Thus, significant improvements on mechanical properties for PVA/LNP/BNNS@HBPL composite fibers were achieved simultaneously, which maintained excellent water resistance in air. Notably, with only 0.5 wt% LNP and 0.3 wt% BNNS@HBPL, the tensile strength and initial modulus reached 12.2 cN/dtex and 153.8 cN/dtex, respectively, representing improvements of 74.2 % and 44.8 % compared to pure PVA fibers. Furthermore, the contact angle was 107.3°, 41.2° higher than pure PVA fiber. The remarkable enhancements make the prepared PVA/LNP/BNNS@HBPL a promising candidate for inexpensive fiber-reinforced concrete.

In this study, we successfully fabricated biocomposite monoliths using a facile, cost-effective, and friendly method via the thermally induced phase separation method using Polystyrene, Lignin, and OV-POSS. The properties of the prepared composites were estimated using Fourier transform infrared measurement (FTIR), scanning electron microscopy (SEM), and thermogravimetric analyzer (TGA). Furthermore, wettability properties were studied using water and oil. FTIR analysis indicates Polyester, Lignin, and OV-POSS were physically blended. The investigation by SEM showed the successful merging of components. Moreover, it revealed that OV-POSS nanoparticles acted as a support for reduced surface roughness. TGA measurements revealed that thermal stability was much better with increased OV-POSS loading. OV-POSS modified monolith exhibited hydrophobic with water contact angles of more than 130°. Results indicate that the produced monolith has a good sorption behavior to oils and organic liquids, whereas PL10L-0.3P showed higher sorption capacities followed by PL10L-0.1P, PL10L, and PL, respectively. The performance of the monoliths on oil/water separation was investigated through the selective removal of oil or organic solvent from water. Hence, the monoliths showed high separation efficiency above 90% and good reusability. The analysis showed that the adsorption for the oil and solvent process followed the pseudo-second-order model with a linear regression coefficient ( R 2 ) of > 0.999. The equilibrium data fit well with the Langmuir model. Besides, thermodynamic parameter analysis results showed that the adsorption was spontaneous and endothermic. An economic study examining the obtained resulted in a rate of investment (ROI) of 38.12%, a breakeven point (BEP) of 44.70%; this research is expected to be useful for the monolith industry that has attractive potential in practical industrial water treatment.
