摘　　要：The MoS_(2)-based materials are a vital class of heterogeneous catalysts for the hydrodeoxygenation of lignin and its model compounds to produce value-added chemicals especially because of their unique selectivity to aromatics.The rational design of MoS_(2)-based catalyst greatly depends on the comprehensive understanding of its structure-activity relationship.However,an intensive summary and critical analysis are still scarce to date.In this review,we attempt to provide an in-depth understanding of the interplay of structure,catalysis,and stability of MoS_(2)-based catalysts for lignin hydrodeoxygenation.The recognition of intrinsic active sites on MoS_(2) structure was firstly discussed,followed by the illustration of MoS_(2)-catalyzed hydrodeoxygenation structural models.Afterward,based on the studies on the MoS_(2)-catalyzed lignin model compounds hydrodeoxygenation,the current active site modification strategies including structural modification of monometallic MoS_(2) catalysts and collaborative modification were summarized and emphatically discussed,which aims to elucidate the structure-activity relationship at the atomic-level.The deactivation mechanism and stabilization strategies were also illustrated to provide instructive suggestion for the rational design of efficient and stable MoS_(2)-based catalysts.Finally,the real lignin depolymerization over MoS_(2)-based catalysts was summarized to point out the advantages and difficulties.This review attempts to highlight the remaining challenges and provide some perspectives for the future development of MoS_(2)-based catalysts for lignin hydrodeoxygenation.
