Biomass, a promising replacement for fossil fuels, can be used to produce eco‐friendly liquid fuels and chemicals. Various studies are investigating catalysts for lignocellulosic biomass conversion to valuable chemicals and fuels. Metal–organic frameworks (MOFs) are important catalysts because of their well‐ordered porous structures and large surface areas. Although MOFs can be applied directly, four modification strategies can be used to alter their catalytic properties and improve catalytic performance. In the first strategy, coordinatively unsaturated sites are created by changing the bonding state of the metal node. In the second approach, organic linkers with additional functional groups or active elements are used. In the third strategy, MOFs and other active elements are combined. In the final approach, MOFs are carbonized to produce carbon‐supported metal catalysts. We review the applications of modified MOFs for the catalytic conversion of biomass derivatives and discuss the factors that contribute to their improved catalytic performance.

改性金属有机骨架作为木质纤维素生物质转化的高效催化剂

生物质有望替代化石燃料，可用于生产生态友好型液体燃料和化学品。各种研究正在研究将木质纤维素生物质转化为有价值的化学品和燃料的催化剂。金属有机骨架（MOF）是重要的催化剂，因为它们有序排列的多孔结构和较大的表面积。尽管可以直接应用MOF，但可以使用四种改性策略来改变其催化性能并改善催化性能。在第一种策略中，通过更改金属节点的键合状态来创建配位不饱和位点。在第二种方法中，使用具有附加官能团或活性元素的有机连接基。在第三个策略中，将MOF和其他活动元素组合在一起。在最后的方法中，MOF被碳化以生产碳载金属催化剂。我们回顾了改性MOF在生物质衍生物催化转化中的应用，并讨论了有助于改善其催化性能的因素。
