英文摘要： The development and utilization of renewable biomass energy are one of the important choice to reduce the emission of carbon and to ensure international energy supply. It is the key technology for high value products to synthsize the 5-hydroxymethylfurfural (5-HMF) from glucose with selective control and to develop the catalyst and reactive process, based on the alternative fossil fuel by biomass. The bifunctional composite mesoporous catalysts with acid and base ,dotted or impregated by transition metals, will be designed and prepared in our application. It will be extensively studied that the changes of the stucture in body phase, surface, defect and coordination of active atom in the surface of catalyst give rise to the influence on the active sites of acid and base and the catalytic reactivity due to transition metals incorporated into the mesoporous materials.The reaction route of isomerization of glucose to synthesize 5-HMF is proposed to elucidate the relation between the structure and catalytic reactivity. The knowledge and mechanism of bond between glucose moleculars up to different composition and structure of catalysts are expected to be recognized. In addition, the preparative program and parameter of catalysts will also be proposed. As above, it will be used to design catalysts with high efficiency. The result will benefit to break through the choke point of the industrial utilization of biomass renewable energy，which is significant in science and industrial application.
