Lignin, an underutilized component of lignocellulosic biomass, is regarded as a rich reservoir for the production of aromatic chemicals and fuels. Despite extensive research in recent years, lignin's potential is far from being fully unlocked. Photocatalysis that uses sustainable solar energy to drive lignin conversion under mild conditions has been identified as a promising strategy and received growing research interest. This review aims to present a critical introduction to the photocatalytic conversion of lignin, including a summary of lignin conversion pathways and mechanisms, as well as the latest cutting-edge innovations on photocatalyst design and reactor construction. Moreover, the screening of solvents and regulation of other key factors that are involved in photocatalytic lignin conversion are also elucidated and future perspectives and challenges for photocatalytic conversion of lignin into valuable products are discussed.
木质素是木质纤维素生物质中未充分利用的成分，被视为生产芳香族化学品和燃料的丰富资源。尽管近年来进行了广泛的研究，但木质素的潜力还远未被充分挖掘。利用可持续的太阳能在温和条件下驱动木质素转化的光催化已被确定为一种很有前途的策略，并引起了越来越多的研究兴趣。本综述旨在对木质素的光催化转化进行批判性介绍，包括对木质素转化途径和机制的总结，以及在光催化剂设计和反应器构建方面的最新前沿创新。此外，还阐明了光催化木质素转化中溶剂的筛选和其他关键因素的调控，并讨论了光催化将木质素转化为有价值产品的未来展望和挑战。
