報告摘要：Lignocellulosic biomass is primarily composed of cellulose (~40%–60%), hemicellulose (~20%–40%), and lignin (~10%–24%). While cellulose and hemicellulose have been widely exploited for the production of microfibrils and C5/C6 chemicals, lignin remains largely untapped due to its complex structure and inherent recalcitrance. As the most abundant aromatic biopolymer, lignin consists of monomeric units connected through robust C–O or C–C bonds. These aromatic constituents could serve as valuable platform chemicals for industries such as perfumery, pharmaceuticals, and agriculture. The cleavage of interunit aryl ether C–O bond linkages, which account for over 50% of all interunit linkages in lignin, is considered a promising strategy for lignin conversion and utilization. However, the effective cleavage of C–O bonds to isolate these monomers remains a significant challenge for industrial applications.
This study presents a comprehensive framework for improving photocatalytic lignin valorization through rational catalyst design. The key advancements include:
? Development of integrated photocatalysts with various functional components for efficient lignin conversion
? Introduction of a water-promoting strategy to enhance reaction kinetics and selectivity
? Refinement of essential reaction steps in the hydrogen transfer and Cα–H bond activation processes
These findings establish a solid foundation for advancing sustainable biomass utilization and scaling up photocatalytic lignin conversion for industrial applications. Future research should focus on optimizing catalyst stability, improving quantum efficiencies, and integrating these processes into biorefinery frameworks.
