In the context of sustainable human development and depletion petroleum resources, lignin has received widespread attention as a carbon-rich, low-cost, renewable resource. Owing to their distinctive physical chemical properties, carbon materials are extensively applied in fields adsorption separation. The conversion into diverse multifunctional materials, such porous carbon, activated fibers, foams, aerogels, emerged pivotal strategy for high-value utilization lignin. this paper, representative examples various lignin-based utilized field separation over past decade reviewed categorized according type preparation methods effects described.

Converting the lignin into value-added chemicals and fuels represents a promising way to upgrade lignin. Here, we present an effective electrocatalytic approach that simultaneously modulates depolymerization hydrogenation pathways of model compounds within single reaction system. By fine-tuning pH electrolyte, achieve remarkable shift in product selectivity, from acetophenone (with selectivity >99%) 1-phenylethanol >99%), while effectively preventing over-hydrogenation. The robust metallic glass (MG) catalyst, endowed with amorphous structure, demonstrates high stability, activity, full recyclability across over 100 consecutive cycles ionic liquid electrolytes. relatively strong affinity MG catalyst for substrate during initial stage, conjunction its weaker binding phenolic product, as progresses, creates delicate balance optimizes adsorption desorption, which is pivotal driving cascade process acetophenone. This work opens versatile upgrading through integrated tandem reactions expands scope design structures.

Lignin, characterized by its amorphous, heavily polymerized structure, is a primary natural source of aromatic compounds, yet complex constitution poses considerable challenges in transformation and utilization. Therefore, the selective cleavage C-C bonds represents critical challenging step lignin degradation, essential for production high-value compounds. In this study, we report simple electrocatalytic approach valorization via bond developing nonmetallic electrocatalyst carbon-based materials. It found that hydrophilicity hydrophobicity have significant effect on degradation process. Under mild conditions, hydrophilic carbon paper exhibits 100% substrate conversion, yielding 97% benzaldehyde 96% quinone with ionic liquid electrolytes. The mechanism study shows catalyst higher surface defects favors electron transfer oxidative process bonds. These results signify substantial advancement offering an environmentally friendly, metal-free electrochemical route.
