SO 4 2−/ZrO 2 and SO 4 2−/ZrO 2–Al 2O 3 catalysts were prepared by impregnation of Zr(OH) 4 and Zr(OH) 4–Al(OH) 3 with ethylene dichloride solution of chlorosulfonic acid, and characterized by ICP-AES, BET, XRD, NH 3-TPD, CO 2-TPD and FTIR of adsorbed pyridine. The catalysts were used in the catalytic conversion of glucose to 5-hydroxymethylfurfural. An optimized 5-hydroxymethylfurfural yield of 47.6% was obtained within 4 h at 403 K over SO 4 2−/ZrO 2–Al 2O 3 with Zr–Al mole ratio of 1:1. The catalyst with higher acidity and moderate basicity was more favorable for the formation of the target product.
