A bionic catalyst for hydrolyzing cellulose and hemicellulose and its preparation method. The catalyst comprises double acid radical catalytic portions and cellulose-linking portions, and can be used under room temperature and high temperature. The catalyst can hydrolyze cellulose and hemicellulose simultaneously, while not decompose glucose and xylose, and may be recycled efficiently. The catalyst can be combined with the process in the prior art to produce liquid fuel.
