Silicon (Si) is regarded as one of the most promising lithium-ion storage materials owing to its large theoretical specific capacity (4200 mAh/g) and low operating potential. However, during lithiation/delithiation processes, the tremendous volume change (~ 300%) and poor conductivity of Si materials restrict their large-scale application in the field of electrodes. Herein, a novel encapsulating strategy was proposed to prepare silicon/carbon composites (650-4-glu). The self-assembly process, driven by electrostatic interaction between lignosulfonate and chitosan, initially enwrapped silicon nanoparticles. Furthermore, glucose was introduced through simple grinding with the lignin-Si-chitosan assembly. After carbonization, physicochemical characterization revealed that the carbon framework derived from lignin-chitosan largely coated silicon, and glucose-derived carbon served as a supplementary phase to enhance the encapsulation effect. The formation of Si-O-C linkages between carbon and silicon tightly bound the silicon particles, which was crucial for improving cycling stability and rate performance. Sample 650-4-glu exhibited an excellent specific capacity, retaining 734.3 mAh/g after 200 cycles at 0.5 A/g and 584.1 mAh/g after 500 cycles at 1.0 A/g. This work demonstrated a sustainable and effective approach for utilizing lignosulfonate, a byproduct in the papermaking industry, in high-performance lithium-ion battery electrodes.

An aqueous Ru-Co bimetallic catalyst system was successfully constructed. • The activity of Ru-Co catalyst was enhanced via sodium lignosulfonate demethylation. • Dicyclohexylmethane and perhydrofluorene were produced under mild conditions. An aqueous bimetallic nanoparticle catalyst system (Ru-Co@DMSLS aq ) was successfully constructed by first modifying sodium lignosulfonate (SLS) via a Na 2 SO 3 -mediated, NaOH-catalyzed method to obtain demethylated SLS (DMSLS). 1 H NMR analysis revealed that the increased hydroxyl content in optimized DMSLS was the key factor enhancing the reduction ability toward metal ions in aqueous solution, thereby yielding Ru and Co nanoparticles with improved catalytic activity. With a precursor ratio of n (Ru 3 O(OAc) 7 )/ n (Co(OAc) 2 ) = 3/2, the resulting Ru-Co@DMSLS aq system featured uniformly dispersed nanoparticles and exhibited outstanding catalytic performance in the hydrogenation of diphenylmethane (DPM) and the hydrodeoxygenation (HDO) of o -hydroxydiphenylmethane ( o -HDPM). Under the conditions of 80 °C, 1.5 MPa H 2 , and 4 h, nearly complete conversion of DPM was achieved with 99.2% selectivity toward dicyclohexylmethane (DCHM). Additionally, a yield of 98.5% for perhydrofluorene (PHF) was attained at 90 °C, 1.5 MPa H 2 , and 4 h in the HDO of o -HDPM. The aqueous bimetallic system enabled favorable product-catalyst self-separation and could be reused five times. This work presents a feasible strategy for valorizing lignin derivatives into low-cost, efficient catalysts for biomass-related hydrogenation processes.

Developing carbon-based adsorbents that simultaneously deliver high CO 2 adsorption capacity and high selectivity is crucial for energy-efficient carbon capture technologies. To overcome the limitations of conventional activators, we employed potassium chloride (KCl) as a single green salt template and successfully converted sodium lignosulfonate into microporous carbon materials (MCMs) by tailoring the ultramicroporous structure through a molten-salt method. The sample prepared at a KCl-to-sodium lignosulfonate mass ratio of 3:1 exhibited a micropore specific surface area of 1452 m 2 /g, with ultramicropores concentrated in the range of 0.3–0.6 nm. At 0 ℃ and 25 ℃ under 1 bar, the maximum CO 2 adsorption capacities reached 5.04 mmol/g and 3.36 mmol/g, respectively. The CO 2 /N 2 selectivity, estimated by ideal adsorbed solution theory (IAST) under simulated flue gas conditions (15% CO 2 /85% N 2 ) at 25 ℃ and 1 bar, reached 20.2. This outstanding combination of high capacity and high selectivity originates from the substantial micropore volume and the enhanced CO 2 pore wall interactions within the narrow ultramicropores, as evidenced by the low-coverage isosteric heat of adsorption of approximately 29 kJ/mol. This study demonstrates that even with a single potassium chloride salt template, precise control over ultramicropore size distribution can be achieved, enabling both high adsorption capacity and high selectivity, and thus provides a promising candidate for post-combustion CO 2 capture and a sustainable route for the valorization of lignin industrial by-products.

Expanders are important additives for lead-acid battery , which reduce the degree of compaction within negative plates and provide more ionically transport channels within the plates during the charge/discharge process. Lignosulfonates (LS) with a 3D structure is one of the most often used expander, which ensures the low compaction of negative plate. However, the insulativity of LS increase cathodic polarization and retard the conversion of PbSO 4 to Pb during charging progress, which intensify the PbSO 4 accumulation in the negative plate and shorten the HRPSoC cycle life of the battery. Focusing on the problems, we used polyaniline-modified lignosulfonates (PANI/LS) composites as expanders. The composites inherit good electronic conductivity of PANI and ionic transport channels from the LS with a 3D structure. Furthermore, the PANI/LS composites havea higher hydrogen evolution over-potential than LS, which avoids the electrolyte dry-out during charging process. The battery tests indicate PANI/LS can refine the size of PbSO 4 particles and promote the conversion of PbSO 4 to Pb. The HRPSoC cycle life of battery with 2PANILS composite expander is 7.3 times longer than that of the battery with LS expander. The negative active material utilization (U NAM ) of the battery containing 2PANILS composite expander is 2 times larger than the battery with LS expander. In addition, the preparation process for the negative plate with 2PANI-LS expander is facile and has potentials for large-scale industrial production.

A simple ion exchange reaction of sodium lignosulfonate (SLS) and 1-allyl-3-methyl imidazolium chloride ([Amim]Cl) produced a new polymeric ionic liquid [Amim]LS and NaCl, and the mixture was successfully used as a precursor to prepare a nitrogen-doped porous carbon material via direct carbonization without any additional activation agent or template. It was believed that the in situ produced NaCl during the precursor synthesis process acted as the self-template and in self-activation. The introduction of imidazolium ionic liquid into the precursor raised the nitrogen content of the obtained carbon material up to 4.68% for a high yield of [Amim]LS-700 carbon material up to 34.6%. The effect of carbonization temperature on the structures and electrochemical properties of the prepared carbon were also studied systematically. It was found that the carbon material exhibits a superior gravimetric capacitance up to 230 F g−1 (0.1 A g−1) at the carbonization temperature of 700 °C, a good energy density of 7.99 W h kg−1 at the power density of 25 W Kg−1, and an excellent cycling stability of 90.3% after 20 000 cycles. This work provides a new path for the value-added utilization of biomass coupled with the field of electrochemical energy storage.

In this study, sodium lignosulfonate modified illite (LS-ILT), an environmentally friendly adsorbent, was prepared by hydrothermal modification. An extensive study of Pb(II) and Cd(II) adsorption behavior and the mechanisms were conducted by evaluating the effects of initial pH value, sorbents dosage, and initial concentration of Pb(II) and Cd(II). Results showed that the adsorption characteristics of Pb(II) and Cd(II) by LS-ILT were well described by quasi-second-order kinetics and the Freundlich model, and the maximum adsorption capacity of Pb(II) and Cd(II) was 42.3 mg/g and 17.0 mg/g, respectively. The optimal application conditions for adsorption equilibrium were the dosage of 4 g/L and reaction pH = 5.5–5.8. The adsorption stability of Pb(II) by LS-ILT was better than that of Cd(II), and most of the existence of coexisting cations had no obvious inhibitory effect on the removal of Pb(II) and Cd(II). Furthermore, the dynamic adsorption results showed that LS-ILT can meet the ultra-low emission standard, and the adsorption capacity could maintain over 50% after four cycles, further providing certain guiding significance for the treatment of wastewater with ultra-low concentrations of heavy metals Pb(II) and Cd(II).

The influence of oxidizer hydrogen peroxide (H 2 O 2 ) on the chalcopyrite and galena flotation separation using sodium lignosulfonate as the depressant was studied and the mechanism of H 2 O 2 enhance depression action of sodium lignosulfonate was discussed in this study. The results show that both chalcopyrite and galena have good floatability when using potassium butylxanthate as a collector. The chalcopyrite and galena flotation separation can be realized by using large doses of sodium lignosulfonate. On the premise of using the oxidant H 2 O 2 , a small amount of sodium lignosulfonate can depress galena completely, but has a weak depression effect on chalcopyrite. Therefore, the dosage of sodium lignosulfonate can be reduced by using H 2 O 2 and sodium lignosulfonate together. Sodium lignosulfonate adsorbed on galena surface principally by chemical reaction with the oxidates generated on galena and H 2 O 2 promote more oxidation products on galena surface, which causes a small amount of sodium lignosulfonate to depress galena. However, the chalcopyrite has high lattice energy, which makes chalcopyrite very stable, so H 2 O 2 has little effect on it. The depressant has low adsorption capacity on the surface of chalcopyrite, and the flotation separation can be realized.

Calcium lignosulfonate, an important natural anionic surfactant widely used in chemical, agricultural and construction applications, was employed to enhance the desulfurization performance of Ca(OH) 2 by adjusting its crystal growth at the atomic level. In the digestion of CaO, calcium lignosulfonate was selectively adsorbed onto the 101 surface of Ca(OH) 2 crystal by the interaction between the sulfonic acid group of calcium lignosulfonate and Ca(OH) 2 surface. The specific adsorption was proved to inhibit the growth of the 101 crystal surface owing to the steric hindrance and electronic interactions. DFT calculations show that the adsorption energy is −1.70 eV, and the change in free energy is negative, indicating spontaneous adsorption. By XRD and SEM characterization results and DFT simulation results, while boost the Ostwald ripening of the 001 surface to form the ultrathin nanosheets with a thickness of 16–21 nm. PDOS simulation results testified that the transferring of lone pair electrons from 2p orbital to the empty 3d-orbitals of calcium and the formation of Ca-O bond because of 0.08 Ha blue shift and broadening of the 2p-orbitals of oxygen. Additionally, the calcium lignosulfonate (CLS) modified Ca(OH) 2 exhibited the increase of BET surface area by 62 % from 30.09 m 2 /g to 48.76 m 2 /g and developed a mesoporous structure with the pore volume of 0.248 cm 3 /g. Consequently, the sulfur capacity of Ca(OH) 2 –15.62 mg/g in comparison to pristine Ca(OH) 2 without CLS, while the penetration times for desulfurization experiments increased from 3300 s to 7600 s.

Driven by the dual carbon goals and large-scale grid integration of renewable energy, developing electrode materials that integrate resource sustainability and high-efficiency energy storage has become a central focus in electrochemical energy storage. Lignin is an excellent precursor for low-cost carbon-based energy storage materials. However, lignin-derived carbon materials often face challenges in pore structure control and synergistic optimization of active site-conductivity performance, which restricts their practical applications. This study employs industrial-grade calcium lignosulfonate as a precursor and adopts a coupled process of “spray-drying with precisely controlled parameters followed by high-temperature carbonization for structural regulation”. This approach successfully produces lignin-derived porous carbon microspheres (CSL) with uniform morphology and controllable pore structures. To elucidate the structure-performance relationship between material structure and electrochemical properties during carbonization, the regulation mechanisms of CSL's microstructure, pore evolution, surface chemistry, and energy storage performance were systematically investigated at three carbonization temperatures (700, 800, and 900 °C). The study revealed that the 800 °C carbonization treatment (CSL-800) constructed a synergistic structure featuring “high-specific-surface-area hierarchical pores + suitable defect active sites + excellent conductivity”, exhibiting optimal energy storage characteristics. In a three-electrode system with 1 M KOH electrolyte, the CSL-800 electrode achieved a high specific capacitance of 345 F g −1 at a current density of 1 A g −1 . It maintained a capacitance retention of 58% when the current density was increased from 1 to 10 A g −1 , demonstrating good rate capability. When assembled into a symmetric supercapacitor, CSL-800 exhibited a remarkable 97.54% capacitance retention after 10,000 charge-discharge cycles under stringent conditions at 10 A g −1 . The device achieved an energy density of 17.13 Wh kg −1 at a power density of 270.4 W kg −1 . This study establishes quantitative relationships among carbonization temperature, structure, and properties, providing theoretical support for optimizing lignin-based carbon materials and promoting the high-value utilization of biomass resources.

Volatile amines generated during meat spoilage provide direct chemical signals for freshness evaluation, but rapidly translating these signals into stable visual responses remains a challenge. Herein, a rapid colorimetric indicator film was developed by incorporating sodium lignosulfonate-regulated ZIF-67 (ZIF-67@SLS) into a sodium carboxymethyl cellulose/pectin (CP) matrix. Modification with SLS endows ZIF-67 with a surface that exhibits greater affinity for amine compounds, thereby enabling it to interact more efficiently with volatile amines associated with meat spoilage. After integration into the CP matrix, CP/ZIF-67@SLS-5% achieved a ΔE of 19.72 after 10 min of NH 3 exposure, representing an 83.8% increase compared to CP/ZIF-67 (ΔE = 10.73), indicating a faster and stronger ammonia-responsive color transition. Meanwhile, the CP/ZIF-67@SLS-5% film maintained good color stability during 21 days of storage at 4, 25, and 50 °C, with ΔE values remaining below 5. The optimized CP/ZIF-67@SLS-5% film also exhibited improved mechanical and barrier performance, with tensile strength and elongation at break reaching 6.49 ± 0.08 MPa and 46.10 ± 2.04%, respectively, and water vapor transmission rate decreasing to 767.71 g m −2 d −1 . When applied to pork freshness monitoring at 4 and 25 °C, the CP/ZIF-67@SLS-5% film displayed visible color transitions from pale purple to brown during storage, enabling timely visual indication of pork spoilage. This work demonstrates that SLS-regulated ZIF-67 can serve as a response-active colorimetric unit for developing rapid ammonia-responsive indicators toward meat freshness monitoring.

While there has been an ongoing effort to develop environmentally friendly multifunctional films made from natural polymers and renewable resources, there are still challenges in realizing versatility through a simple and green process. Here, we use aqueous alkali to rapidly dissolve modified cellulose fibers above 0 °C within minutes to prepare cellulose hydrogel substrate. The modified cellulose can be commercially obtained from carboxymethyl cellulose manufacturing with low cost. Subsequently, a biodegradable multifunctional all-biomass composite film is obtained by wrapping sodium lignosulfonate (LSS) and phosphorylated sodium alginate (PSA) molecules in cellulose hydrogel. The films exhibited excellent UV protection, blocking 86–99.3% of UV-A and 99.6–100% of UV–B radiation. Meanwhile, the films blocked 57.4–90.7% of high-energy blue light (HEBL, 400–450 nm) and maintained 66.2–80% transparency at 600 nm. The films effectively block blue light from sources such as computer screens, mobile phones, and lighting systems by means of light absorption. The films outperformed commercial shielding films in UV and HEBL blocking. Notably, the films acquired excellent flame-retardant performance with the addition of PSA, achieving a high limiting oxygen index (LOI) of 33.3%. In comparison with the original one, the composite film exhibited a 75.6% reduction in peak heat release rate and an 84.6% decrease in total heat release. Moreover, the films have ideal biodegradability and mechanical strength, with a tensile strength exceeding 98 MPa. This sustainable and clean strategy would direct all-biomass films toward diversified applications.
