摘　　要：对磺化碳基固体酸制备原料及制备方法进行系统介绍,分析磺化碳基固体酸物理化学结构与其催化纤维素水解的构效关系,讨论碳基固体酸失活原因及分离回收方法。针对磺化碳基固体酸与纤维素间的传质限制,总结归纳先“降结晶、再水解”的纤维素高效水解策略。最后对磺化碳基固体酸的未来研究重点和前景进行展望,以期为促进磺化碳基固体酸在木质纤维素糖平台构建中的创新发展提供科学参考。In this paper,raw materials and preparation methods of sulfonated carbon-based solid acids were systematically introduced,the physicochemical structure of sulfonated carbon-based solid acids was analyzed in terms of their conformational relationship with cellulose hydrolysis.The reasons for deactivation of carbon-based solid acids and their separation and recovery methods were discussed.In view of the mass transfer limitations between solid acids and cellulose,a high-efficiency catalytic strategy named“first reducing crystallization and then hydrolysis”were summarized.Finally,the future research focus and prospects of sulfonated carbon-based solid acids were prospected,which provide scientific references for promoting the innovative development of sulfonated carbon-based solid acids in the construction of lignocellulosic sugar platforms.
