In this paper, a silicalite-1 modified HY zeolite (HY/silicalite-1) was prepared and applied as an efficient catalyst to promote the hydrolysis of microcrystalline cellulose to glucose in ionic liquid 1-ethyl-3-methylimidazolium chloride ([Emim]Cl). Scanning Electron Microscope reflects a core–shell morphology of HY/silicalite-1. When using HY/silicalite-1 as catalyst instead of non-modified HY, the glucose selectivity could be significantly improved, and the hydrolysis temperature could also be reduced to 110 °C. Under optimal conditions, 93.5% of total reducing sugar and 50.8% of glucose yield were obtained within 8 h of the reaction. The mechanism with respect to the hydrolysis of cellulose over HY/silicalite-1 was fully discussed. The improved sugar selectivity may due to reduced Lewis acidity of modified HY. Moreover, the reduced contact probability of sugar with the Lewis acid cites of catalyst caused by the outer silicalite-1 layer may also contribute to the good sugar selectivity.
