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.

摘要

固体酸作为纤维素水解的多相催化剂越来越受到关注。然而，目前的固体酸面临着催化剂负载量高（催化活性低）、催化剂-底物相互作用差、水热稳定性差和可回收性不理想等挑战。这篇综述批判性地讨论了最近在克服固体酸问题和开发用于水解纤维素的高性能固体酸方面的努力和进展。详细讨论了固体酸的关键结构特征及其对与纤维素和纤维素水解的相互作用的影响。提供了提高固体酸的性能、水热稳定性和可回收性的策略和观点。
