| 中文摘要: |
| 固体酸水解纤维素制备葡萄糖因具有无腐蚀、易回收等优点逐渐成为研究热点，但仍存在固体酸与纤维素接触困难、水解效率低等问题。为了克服传统固体酸存在的缺点，模仿纤维素酶水解机理，在固体酸上引入纤维素结合基团（CBD）以合成仿酶固体酸，通过CBD分别与纤维素和低聚糖形成氢键作用来提高纤维素水解效率。本文分析了仿酶固体酸水解纤维素的过程和机理，总结了几种常用仿酶固体酸的制备方法和对纤维素的水解效果，并对未来更绿色、简单、廉价、高效的纤维素水解工艺提出了展望。 |
| Abstract: |
| Traditional solid acid has been sought after as the advantage of no corrosion， easier to recover and reuse， etc. However， the traditional solid acids generally have the problem of poor affinity to cellulose and lower hydrolysis efficiency. In order to overcome the above-mentioned drawbacks， mimicking the cellulase hydrolysis mechanism， a cellulose binding group （CBD） was introduced to synthesize the enzyme-mimic solid acid which can improve the cellulose hydrolysis efficiency by forming hydrogen bonds between CBD and cellulose and oligosaccharide. In this review， the process and mechanism of hydrolysis of cellulose by enzyme-mimic solid acid were analyzed， and the preparation methods and hydrolysis effects of several commonly used imitation enzyme solid acids were summarized. Finally， some research trends in the future were also prospected to provide some valuable ideas for the hydrolysis of cellulose into glucose in a more green， simple， efficient and inexpensive way. |
