摘　　要：The development of novel methods to obtain biofuels and chemicals from biomass has been an immediate issue in both academic and industrial communities. In this work, a series of novel catalysts were prepared and character- ized by FT-IR, TGA, XRD, SEM, TEM, ICP-AES, NH3-TPD and BET, which were applied for the conversion of hexose to 5-hydroxymethylfurfural （HMF）. The Cr（Salten）-MCM-41-[（CH2）3SO3HVIm]HSO4 catalyst was the most active catalyst, and a glucose conversion of 99.8% with 50.2% HMF yield was obtained at 140 ℃ for 4 h in dimethyl sulfoxide （DMSO）. The effects of reaction temperature, reaction time, solvents and catalyst dosages were investigated in detail. MCM-41 immobilized acidic functional ionic liquid and chromium（III） Schiff base complex- es as heterogeneous catalysts can be easily recovered by simple filter treatment, exhibiting excellent stability and activity towards hexose conversion. Thus the heterogeneous catalysts were environment-friendly for transforming biomass carbohydrates into fine chemicals.The development of novel methods to obtain biofuels and chemicals from biomass has been an immediate issue in both academic and industrial communities.
