Abstract: A method for hydrolyzing cellulose is provided to suppress by-products, to be environment-friendly and to improve the yield while increasing the production rate of glucose. A method for hydrolyzing cellulose comprises (i) a step for pre-processing the cellulose by adding the ionic liquid in the cellulose; and (ii) a step for hydrolyzing the cellulose by adding a solid acid-catalyst to the pre-processed cellulose. The solid acid-catalyst is the zeolite.
