摘　　要：木质素是世界上唯一可生产芳香族化合物的可再生资源。金属-有机框架(MOFs)具备金属节点、有机配体和孔结构可灵活功能化的优势,利用MOFs催化木质素高效解聚制备高值酚类单体及其衍生物是木质素资源化利用的最有前景的途径之一。本文介绍了木质素的种类与结构特点,以及MOFs的结构和合成策略,以酚类单体及其衍生物为目标产物,着重介绍了木质素解聚生产酚类单体及其衍生物环烷烃、环己醇的最新进展,并对木质素解聚过程中化学键断裂、官能团加氢脱氧机理进行了归纳。最后,总结了当前MOFs催化木质素解聚存在的问题,并提出了未来可能的发展方向。Lignin,the only renewable resource in the world,can produce aromatic compounds.Metal-organic frameworks(MOFs)have the advantages of flexible functionalization of metals nodes,organic ligands and pore structures.The efficient depolymerization of lignin catalyzed by MOFs to prepare high-value added phenolic monomers and their derivatives is one of the most promising approaches for the resource utilization of lignin.This paper introduced the types and structural characteristics of lignin,as well as the structure and synthesis strategies of MOFs.Moreover,taking phenolic monomers and their derivatives as the target products,the latest research progress in lignin depolymerization to produce phenolic monomers and their derivatives cycloalkanes,and cyclohexanols were emphatically introduced.In addition,the mechanisms of chemical bonds cleavage and functional groups hydrodeoxygenation by lignin depolymerization were summarized.Finally,the existing problems of MOFs catalyzing lignin depolymerization at present were summarized,and possible future development directions were proposed.
