| 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. |
