Effective hydrolysis of cellulose to glucose is a crucial step to utilize lignocellulosic biomass for fuels and chemicals. In this study, we adopted the simple Blanc chloromethylation of commercially available Amberlyst-15 to fabricate enzyme-mimic solid acid (A-15-Cl) for cellulose hydrolysis. The results indicated that the chlorine group in A-15-Cl adsorbed cellulose and particularly oligosaccharides through hydrogen bonding while the sulfonic acid group cleaved the β-1,4 glycosidic bonds in cellulose and oligosaccharides. Due to the synergistic effect between the chlorine (adsorbing cellulose) and sulfonic acid (hydrolyzing cellulose) groups, A-15-Cl effectively hydrolyzed cellulose in water achieving a 67.2% glucose yield at 170 °C in 2 h. Moreover, A-15-Cl can be readily separated from the reaction medium by an 80-mesh screen for reuse at least five times without significant loss of catalytic activity.

有效地将纤维素水解为葡萄糖是将木质纤维素生物质用于燃料和化学品的关键步骤。在这项研究中，我们采用了市售的Amberlyst-15的简单Blanc氯甲基化方法来制造酶模拟的固体酸（A-15-Cl），用于纤维素水解。结果表明，A-15-Cl中的氯基通过氢键吸附纤维素，特别是低聚糖，而磺酸基裂解纤维素和低聚糖中的β-1,4糖苷键。由于氯基团（吸收性纤维素）和磺酸基团（水解纤维素）之间的协同作用，A-15-Cl有效地水解了水中的纤维素，在170°C下2小时的葡萄糖收率达到67.2％。此外，
