摘要固体酸作为纤维素水解的非均相催化剂越来越受到人们的关注，然而，目前的固体酸面临着诸如催化剂负载量高（催化活性低）、催化剂-底物相互作用差、水热稳定性不足和可回收性不令人满意等挑战。本文综述了近年来在克服固体酸存在的问题和开发高效水解纤维素的固体酸方面所做的努力和取得的进展。详细介绍了固体酸的主要结构特征及其对纤维素相互作用和纤维素水解的影响。提出了提高固体酸性能、水热稳定性和可回收性的策略和前景。
ABSTRACT Solid acids as heterogeneous catalysts for cellulose hydrolysis have drawn increasing attention; however, current solid acids face challenges such as high catalyst loading (low catalytic activity), poor catalyst-substrate interaction, deficient hydrothermal stability, and unsatisfactory recyclability. This review critically discussed the recent efforts and progress in overcoming the issues of solid acids and developing high-performance solid acids for hydrolyzing cellulose. The key structural features of solid acids and their effects on the interactions with cellulose and cellulose hydrolysis were addressed in detail. Strategies and perspectives to enhance performance, hydrothermal stability and recyclability of solid acids were provided.
