Abstract Carbon fibers (CFs) with notable comprehensive properties, such as light weight, high specific strength, and stiffness, have garnered considerable interest in both academic industrial fields due to their diverse advanced applications. However, the commonly utilized precursors, polyacrylonitrile pitch, exhibit a lack of environmental sustainability, costs are heavily reliant on fluctuating petroleum prices. To meet substantial market demand for CFs, significant efforts been made develop cost‐effective sustainable CFs derived from biomass. Lignin, most abundant polyphenolic compound nature, is emerging promising precursor which well‐suited production its renewable low cost, carbon content, aromatic structures. Nevertheless, majority lignin raw materials currently pulping biorefining by‐products, heterogeneous restricting industrialization lignin‐derived CFs. This review classifies fossil‐derived biomass‐derived starting sources chemical structures lignin, outlines preparation methods linked performance A discussion presented relationship between structural characteristics spinning preparation, structure‐morphology‐property Additionally, potential applications these various domains, including energy, catalysis, composites, other products, also described objective spotlighting unique merits lignin. Finally, current challenges faced future prospects advancement proposed.

ConspectusThe increasing demand for polymeric materials derived from petroleum resources, along with rising concerns about climate change and global plastic pollution, has driven the development of biobased materials. Lignin, which is second most abundant biomacromolecule after cellulose, represents a promising renewable raw material source preparation advanced The lucrative properties lignin include its high carbon content (>60 atom %), thermal stability, biodegradability, antioxidant activity, absorbance ultraviolet radiation, slower biodegradability compared to other wood components. Moreover, advent nanoparticles (LNPs) over last ten years circumvented many well-known shortcomings technical lignins, such as heterogeneity poor compatibility polymers, thereby unlocking great potential functional materials.LNPs stand out owing their well-defined spherical shape excellent colloidal due electrostatic repulsion forces carboxylic acid phenolic hydroxyl groups enriched on surface. These prevent aggregation in aqueous dispersions (pH 3-9) provide surface area mass ratio that been exploited adsorb positively charged compounds enzymes or polymers. Consequently, it not surprising LNPs have become prominent player applied research areas biocatalysis composites, among others. However, like all ventures life, also face certain challenges limit end-uses. Solvent instability remains challenging aspect tendency these particles dissolve aggregate organic solvents basic acidic pH, thus limiting window chemical functionalization applications. In addition, need solvent during preparation, miscibility hydrophobic matrices, nascent phase regarding use smart identified important be addressed.In this Account, we recapitulate our efforts past overcome main limitations mentioned above. We begin brief introduction fundamentals detailed discussion associated challenges. then highlight work on: (i) Preparation lignin-based nanocomposites improved through controlled dispersion within matrix, (ii) Stabilization via covalent (intraparticle cross-linking) noncovalent (hydration barrier) approaches, (iii) an organic-solvent-free method production LNPs, (iv) toward content. Finally, offer perspectives rapidly growing field.

Abstract As the most abundant renewable aromatic biopolymer resource on Earth, lignin has become a cutting‐edge research hotspot in clean photocatalysis, thanks to distinct highest occupied molecular‐orbital and lowest unoccupied energy levels driven by major β‐O‐4 linked bonds. However, complex spatial architecture of functional groups, represented benzene rings 3D intertwined macromolecular chains lignin, challenge enhancing carrier separation efficiency remain persistent obstacles hindering development lignin‐based photocatalysts. Herein, strategy constructing nanosphere‐graphene oxide heterointerfaces (EL‐GO) is proposed comprehensively enhance efficacy groups facilitate photoelectron migration modes. The recombination time light‐excited photoelectrons effectively prolonged π‐π interactions between “Donor site” “Acceptor regions, along with directional EL GO. photocatalytic H 2 O production using EL‐GO significantly enhanced under protective mechanism To assess its potential, prospect estimation lake containing various pollutants metal ions was conducted, simulating real water conditions. This pioneering engineering effort aims curb excessive consumption fossil fuels explore green applications thereby “carbon‐neutral” feedstock system.
