As a green and sustainable porous material, wood has attracted more and more attention of researchers, especially in the field of energy storage. However, the poor conductivity of wood limits its application. Herein, a kind of non-carbonized lignin-free wood (LFW)@PANI supercapacitor material is fabricated for renewable energy storage application. The resultant hybrid used as electrode material of supercapacitor shows a good comprehensive electrochemical performance: 1) A high cycle stability of ~96% after experiencing 5000 cycles. 2) A high specific capacitance of ~800 F g −1 and 192 F cm −3 3) Good rate performance. 4) A high energy efficiency of more than 80%. 5) High energy densities of 41 Wh kg −1 (57 Wh L −1 ), meanwhile maintaining high power densities of 43 kW L −1 (68 kW kg −1 ). Compared with the way of carbonization , non-carbonized treatment not only save energy but also be greener. This work is expected to provide more insights and possibilities for application of renewable wood-based materials.

Typically, SiO 2 , Al 2 O 3 , MOF, and polymers are used to prepare solid amine CO 2 adsorbents. In this manuscript, we explored abundant lignin waste to prepare a series of solid amine CO 2 adsorbents via in situ Mannich reactions with commercially available, cheap ethanolamine and polyethyleneimine. Upon optimization of amine loadings and reaction conditions, the novel ethanolamine modified adsorbents showed significantly improved CO 2 capture performance (6.83 mmol/g) compared to native lignin (2.57 mmol/g) under laboratory testing conditions (25 ° C, 1 bar, and 10 vol% CO 2 /Ar). Unfortunately, the captured CO 2 can be regenerated with a maximum limit of 50% under rather harsh conditions, implying likely utilization of the cheap adsorbents loaded with CO 2 as building fillers and adhesives. Elemental analysis, scanning electron microscopy, x-ray photoelectron spectroscopy, thermogravimetric analyzer, CO 2 adsorption isotherm, and Fourier transform infrared spectrometer analysis were applied to characterize the texture properties and CO 2 capture mechanisms.

Lignin valorization is a challenge for chemical and materials scientists due to its complex molecular structure and intra- and inter-molecular assembly. Although catalytic conversion of lignin into small aromatic organic molecules has been widely investigated, it faces the problems of low selectivity and complex products. Herein, we report a direct electrochemical conversion method for the selective oxidation of industrial lignin to produce short-chain carboxylic acids (SCCAs) with a wide range of concentrations. In an electrolytic cell, lignin is chemically converted to SCCAs by H2O2 with titanium silicate-1 (TS-1) as a catalyst. H2O2 is generated in situ by the recombination of H+ and HO2− in a three-compartment cell by separately introducing hydrogen (H2) and oxygen (O2) as the sources of protons and HO2− into the anode and cathode compartments. We have achieved a record-high concentration of SCCAs up to 109.8 mg mL−1 through the catalytic depolymerization of lignin. A high concentration of SCCAs of 80.1 mg mL−1 could also be achieved at a cell voltage of 2.13 V by coupling the 2e−-ORR and water oxidation using air and 1 M aqueous H2SO4 solution as feedstocks. Our approach could eliminate the additional economic consumption and environmental hazards caused by the transportation and storage of commercially concentrated and stabilized H2O2. Aside from the SCCAs produced in this process, the formation of new carboxyl groups in the lignin residue during the oxidation reaction greatly broadens the application potential of industrial lignin.

Bio-based adhesives are becoming increasingly popular due to their environmentally friendly characteristics. However, owing to the hydrophilic nature and low reactivity of biomass, it is still somewhat difficult to attain long-term water resistance. Moreover, achieving flame retardancy and mold resistance poses an even greater challenge. In this work a unique adhesive has been conceived and prepared from epoxy lignin (EL) and polyamide (PA) solving these issues. The covalent cross-linked network, generated by reaction of EL and PA respective epoxy and amino groups, has yielded an adhesive of outstanding water resistance. The plywood bonded with this adhesive met the standards of class I plywood of the Chinese national standards (GB/T 17657–2022), and the wet strength after boiling in water for 72 h reached 0.87 MPa. This adhesive did also show resistance to extreme environments, including strong acids, strong alkalis, seawater, and organic solvents. Moreover, it was shown to be capable of bonding diverse organic and inorganic substrates. Its bonding performance significantly surpassed that of commercial wood adhesives. Furthermore, owing to the formation of a carbon layer that isolated oxygen during the combustion of lignin, this adhesive exhibited excellent flame-retardant properties. Specifically, its Limiting Oxygen Index (LOI) was as high as 39.1%. Simultaneously, the EL-PA adhesive also presented remarkably good anti-mold properties. In the 40-day anti-mold experiment, no mold growth was detected on either the adhesive or its raw materials. This work is expected to offer a promising, partially eco-friendly alternative to traditional formaldehyde-based adhesives.

Although lignin is the second most abundant forest biomass polymer, it has been largely neglected in hydrogel electrolytes due to its insolubility and inflexibility. In this study, a double-crosslinked hydrogel was prepared using aspartic acid-modified lignin and sodium alginate, significantly improving the mechanical properties. The hydrogel exhibited an exceptional strain of 3008% and a tensile strength of 0.03 MPa, demonstrating its remarkable mechanical properties. In addition, high ionic conductivity (11.7 mS·cm −1 ) was obtained due to the abundant presence of hydrophilic groups in the hydrogel. The hydrogel-assembled supercapacitor manifested an impressive specific capacitance of 39.46 F·g −1 . Notably, the supercapacitor showed a wide potential window of 0–1.5 V and achieved a maximum energy density of 5.48 Wh·kg −1 at the power density of 499.9 W·kg −1 . The capacitance retention remained at 115% after 10000 charge-discharge cycles. Finally, the coulombic efficiency was almost 100% during the cycles. Upon reaching a bending angle of 90°, the specific capacitance retention remained impressively high at 94%. These results suggest that the supercapacitor cans maintain normal electrochemical performance under extremely harsh conditions.

Graphical Sticky trees : Reusable, self-healable, removable, and strong lignin-containing polyurea adhesives were successfully prepared via introducing polyetheramine-grafted lignin and a chain extender containing disulfide bonds. Lignin contributed to the enhanced adhesion via constructing intensive hydrogen bonding interactions whereas the dynamic disulfide bonds played a key role for reuse performance and self-healing ability. Reusable, self-healable, removable, and strong bio-based polyurea adhesives were successfully synthesized via partially substituting polyetheramine with polyetheramine-grafted lignin and introducing a chain extender containing dynamic disulfide bonds. The polyetheramine-grafted lignin endowed the polyurea adhesives with significantly enhanced adhesion strength on either metal or wood substrates by introducing intensive hydrogen bonding interactions; the dynamic disulfide bonds played a key role in the excellent self-healing and reusable performance. The thermostability of polyurea adhesives was also improved by introducing lignin. This work provides a novel approach for the high-value utilization of low-cost lignin in recyclable adhesives with excellent comprehensive performance.

The enzymatic hydrolysis of lignocellulose continues to be encumbered by elevated production costs and diminished cellulase efficiency. In this work, modified DES recovered lignin was obtained by grafting acrylamide and acryloyl chloride to enhance glucose release. At a cellulase dosage of 5 FPU/g-cellulose and pH of 5.5, modified lignin promoted glucose yield of dilute-acid-pretreated wheat straw by 158% compared with control. The mechanism by which modified lignin promotes enzymatic hydrolysis was further explored. The binding constant was reduced from (3.3510±0.8361)*10 4 to (2.7600±0.6027)*10 3 L•mol -1 after modification. Modified lignin could make α-helix content enhancement so that cellulase had a compact and stable spatial structure. Lignin binds within the catalytic tunnel of cellulase and that the modified lignin interacts with cellulase with increased hydrogen bonding, resulting in a more compact cellulase structure. The modified lignin might reduce the unproductive adsorption of cellulase, and increase stability and cellulose accessibility to reduce cellulase cost.

Solar-driven interfacial evaporation technology has emerged as a promising solution for heavy metal-containing wastewater treatment, owing to its environmentally friendly and sustainable energy input advantages. However, the development of low-cost, high-efficiency photothermal agents with enhanced heavy-metal ion tolerance remains a significant challenge for advancing practical solar-powered wastewater treatment. Herein, we developed a series of metal-lignin composites, through a one-pot reaction involving lignin and heavy metal-contained wastewater, which demonstrated outstanding light-harvesting efficiency and photothermal conversion properties. The resulting metal-lignin composites can be efficiently fabricated into evaporators via 3D printing technology for wastewater treatment. The optimized evaporator achieves an exceptional water evaporation rate of 2.88 kg m − 2 h −1 under 1-sun irradiation while demonstrating outstanding performance in both seawater and heavy metal-containing wastewater systems. Moreover, the evaporator exhibits no significant decline in evaporation rate during continuous wastewater treatment over 7 days, highlighting its exceptional durability and long-term stability. Finally, techno-economic analysis estimates the production cost of clean water by the evaporator at 0.372 $ m − 3 , below the industry average and even approaching the globally reported lowest threshold for reverse osmosis desalination. This work is believed to offer valuable insights into achieving cost-effective and highly efficient solar-driven wastewater purification technologies from lignin.

This study reported a modified hydrothermal solvent method for preparing lignin microspheres (LNSs) with controllable size and morphology by precisely regulating the reaction temperature (160–220 °C). Fourier transform infrared (FTIR) spectroscopy and scanning electron microscopy (SEM) were employed to evaluate the structure, morphological, and dimensional attributes of lignin microspheres, and the synthesis mechanism was discussed. The antibacterial efficacy of the hydrothermally treated lignin microspheres (HTLNSs) was evaluated through phosphate-buffered saline (PBS) culture assays, as well as by assessing nucleic acid and protein leakage, and their inhibitory effect on cell membrane permeability. Among the synthesized samples, HTLNS-180 demonstrated superior bacteriostatic properties, achieving the highest nucleic acid content and bacterial cell permeability post-treatment, suggesting significant bacterial cell wall disruption. Its antibacterial inhibition rate reached 51.0 % against Staphylococcus aureus ( S. aureus ) and 54.3 % against Escherichia coli ( E. coli ). The study provides new insights into the structure-property relationship of lignin-based nanomaterials and their potential in biomedical and antimicrobial applications.

To develop a green solvent for lignin dissolution, the most fundamental aspects of its mechanism must be elucidated. Understanding the thermodynamic behaviors is of significant importance for designing novel deep eutectic solvents (DESs) to dissolve lignin. Herein, the heat of dissolution of lignin in acidic, alkaline or neutral DESs was determined by high-precision solution microcalorimetry, and comprehensively investigated the effect of physicochemical properties of DESs on the heat of dissolution and solubility of lignin. The resulted observed that lignin dissolution in alkaline DESs was more vigorous exothermic than that in acidic and neutral DESs. The thermodynamic parameters for the dissolution of lignin in the DESs were calculated from the heat of dissolution and solubility. The positive free energy change indicated that the process of lignin dissolution was non-spontaneous and unfavorable thermodynamically. By analyzing the changes of enthalpy and entropy of lignin solution systematically, lignin dissolution in DESs was enthalpically favorable and controlled by the entropy term. Especially, the interaction entropy predominantly made the free energy change unfavorable for lignin dissolution. The achieved thermodynamic findings could serve as the basis to construct robust DESs for lignin biorefinery.

Optimizing the durability and degradability of polymers is essential for prolonging their useful life and minimizing their environmental footprint post-use, contributing to a sustainable world; however, durability in many cases conflicts with degradability. In this context, we developed lignin-based waterborne polyurethane (WPU) composites that bypass this dichotomy. Lignin nanoparticles (LNP), derived from enzymatic hydrolysis lignin (EHL), were synthesized using the anti-solvent method and incorporated into WPU emulsions through solution blending. The introduction of 5 wt% LNP notably improved the tensile strength of WPU composites, increasing it from 21.5 MPa to 29.7 MPa, a surge of up to 38 %. Moreover, 5 wt% of LNP significantly enhanced the durability of WPU by reducing creep strain (under a stress of 1 MPa for 3000 s) from 606 % to 70 % with an 88 % decrease, and by increasing molecular weight retention rate from 11 % to 87 % after 15 days of UV exposure. Concurrently, LNP notably accelerated the alkaline degradability of WPU/LNP composites, with weight loss rate increasing from 38 % to 92 % (a 142 % increase) and molecular weight loss from 17 % to 44 % (a 159 % increase), compared to pure WPU. The strategy employed in this study leverages the inherent properties of LNP to offer a promising approach to enhancing polymer sustainability, presenting an effective solution to the significant end-of-life challenge.

Membrane separation technology can efficiently separate contaminants to achieve wastewater resource recovery and purification. Although photocatalytic membranes offer an effective route for self-cleaning, the highly reactive radicals generated during photocatalysis inevitably attack and degrade polymer substrates, compromising long-term stability. To address this limitation, the natural lignin was coordinated into photocatalytic membranes, serving dual functional roles. First, lignin as a sacrificial agent preferentially reacts with reactive oxygen species, thereby effectively protecting the polymer chains from oxidative damage. Second, under UV irradiation, part of the lignin undergoes controlled degradation, during which its aromatic ring structures are cleaved and hydrophilic oxygen-containing functional groups are generated in situ. This process simultaneously enhances surface hydrophilicity and increasing porosity. The optimized membrane exhibited a BSA solution filtration flux of 53.3 L·m −2 ·h −1 and rejection of 97.1%. After UV irradiation, the membrane demonstrated a substantially enhanced pure water flux, stabilizing at 157.9 L·m −2 ·h −1 . Furthermore, during long-term cyclic separation tests with landfill leachate, the membrane achieved a flux recovery ratio over 100%. This work not only provides a novel strategy for mitigating membrane fouling, but also opens a new pathway for the high-value utilization of biomass resources.
