Abstract Developing novel techniques to convert lignin into sustainable chemicals and functional materials is a critical route toward the high-value utilization of lignocellulosic biomass. Lignin-derived carbon hold great promise for applications in energy chemical engineering, catalysis environmental remediation. In this review, state-of-art sciences technologies controllable synthesis lignin-derived are summarized, pore structure crystalline morphology controlling methodologies thoroughly...
Abstract The development of high‐performance carbon anode for sodium‐ion batteries is limited by the sluggish kinetics and structural instability. Expanded interlayer spacing, nitrogen doping, mesoporous structure engineering have emerged as promising strategies to overcome these challenges. Simultaneously achieving graphene nanodomains construction, high‐efficient rational challenging. Herein, a strategy pyrolyzing SiO 2 @ lignin amine urea‐formaldehyde resin proposed deliberate...

The conversion of renewable bioethanol into high-energy-density higher alcohols has become essential for meeting the increasing global demand to achieve carbon neutrality. In this study, Zn- and nitrogen-codoped Ni-based lignin-derived catalysts (NiZn@NC) were prepared by solvent volatile self-assembly in situ reductive carbonization using pulp paper waste stream alkali lignin as source. Lignin amphipathic derivatives with −COOH −NH2 groups would coordinate metal ions form a stable...
The selective breaking of the Cβ–O bond has great potential for conversion lignin into high-value aromatic monomers. In present work, we designed a CdS–SH/TiO2 heterojunction photocatalyst efficient bond. surface modification CdS by –SH promoted close contact between catalyst and further Fermi level matching with TiO2. A type-II was constructed CdS–SH TiO2 nanosheets to enhance light absorption range increase separation photogenerated electron–hole pairs, resulting in high catalytic...

We successfully applied reaction kinetics based combined hydrolysis factor ( CHF X ) as severity quantitatively control xylan dissolution and BEP fibril deploymerization. More importantly, were able accurately predict the degree of polymerization (DP) disk-milled fibrils...
Amorphous carbon monoliths with tunable microstructures are candidate anodes for future lithium-based energy storage. Enhancing lithium storage capability and solid-state diffusion kinetics the precondition practical applications. Transforming intrinsic oxygen-rich defects into active sites engineering enlarged interlayer spacing of great importance. Herein, a novel explosion strategy is designed based on oxalate pyrolysis producing CO CO2 to successfully prepare lignin-derived monolith...
Photocatalysis coupling of H2 evolution and lignocellulose oxidation remain great foreground, but slow photodynamic process limits its development. Here, we explored the effect defect engineering on electronic structure d-band center Pt/TiO2 catalyst. Oxygen vacancies lead to delocalization electrons near O atom, moves down, which will redistribute facilitate desorption intermediates The density functional theory results indicate that Pt TiO2 surfaces form electron-rich electron-deficient...

Lignin-based carbon dots (LCDs) have attracted increasing attention, but their limited regulation and the use of harmful chemicals in preparation hindered applications. In this study, we successfully produced LCDs by heating lignin dissolved a green solvent system, binary γ-valerolactone (GVL) water. Furthermore, were able to easily regulate fluorescence properties adding environmentally friendly chemicals, such as urea citric acid, solution. As result, emitting was shifted from blue light...
Carbon aerogels possess low density, high conductivity, and excellent electrochemical properties, which have potential applications in sensor energy storage. However, the fabrication methods of carbon are very complicated, usually restricted by their compressibility, fragile structure, poor electrical property.

Experimental theoretical evidence reveal that this enhanced performance due...
Lignin, a natural aromatic polymer, is promising candidate for sustainable photonic materials. However, its heterogeneity hinders uniform nanoparticle production. This study employs membrane ultrafiltration to fractionate alkaline lignin into five molecular weight fractions (UL1-UL5) and synthesizes nanoparticles (LNPs) via antisolvent self-assembly. Low-molecular-weight yielded highly uniform, monodisperse LNPs (PDI < 0.1), while higher-molecular-weight produced irregular particles....
