SO42-/ZrO2 and SO42-/ZrO2-Al2O3 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, NH3-TPD, CO2-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 SO42-/ZrO2-Al2O3 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. (C) 2009 Published by Elsevier B. V.
