摘要:近年来，木质素催化解聚已从单一高转化率目标转向高值化应用导向策略，其关键在于促进木质素选择性断键和芳香结构释放的同时，实现木质素分子的可控活化和中间体稳定，以提高目标产物选择性。为促进木质素的定向转化，本文深入探讨了木质素结构对其催化解聚反应性能的影响规律，介绍了调控反应路径和目标产物选择性的木质素催化解聚方法学，分析了主要催化体系的作用路径和应用特点。此外，围绕催化微环境设计和生物漏斗转化等木质素转化升级新方向，综述了木质素催化解聚产物在化学品、燃料和功能材料等高值化应用中的转化路径和调控手段，阐述了应用导向下，木质素差异化利用的“原料结构-催化位点-转化路径-目标产品”适配策略，最后对木质素催化解聚技术的发展趋势和面临的挑战进行了总结。
Abstract:In recent years， lignin depolymerization has shifted from a single high conversion rate target to a strategy oriented towards high-value utilizations. The key lies in promoting the selective bond cleavage and release of aromatic structures of lignin， while achieving the controlled activation of lignin molecules and the stability of intermediates to enhance the selectivity of the target products. To promote the directed conversion of lignin， this paper deeply explored the influence rules of lignin structure on its catalytic depolymerization reaction performance， introduced the lignin catalytic depolymerization methodologies for regulating reaction pathways and target product selectivity， and analyzed the action pathways and application characteristics of the main catalytic systems. In addition， around new directions for lignin conversion upgrades such as catalytic microenvironment design and biological funnel conversion， this paper reviewed the conversion pathways and regulation methods of lignin catalytic depolymerization products in high-value utilizations， such as chemicals， fuels， and functional materials. It elaborated on the “feedstock structure-catalytic site-conversion path-target product” matching strategy for the differentiated utilization of lignin under the application-oriented approach. Finally， it summarized the development trends and challenges of lignin catalytic depolymerization technology.
