英文摘要: Exploring value-added chemicals from renewable biomass resources using catalytic technology is one of the frontiers in catalytic chemistry. A new method to establish the glucose isomerization, selective dehydration and in-situ oxidation is a significant route for glucose high-value utilization, and also may provide a reference for other carbohydrates conversion. In this proposal, we will use the methods of cocondensation and inverse microemulsion to realize the controllable preparation of catalytic materials in size, morphology and structure and to construct novel isomerization, selective dehydration and in-situ oxidation multifunctional catalytic materials. The new preparation methods of hydrophobic solid acids will be explored, and the activation of C-OH bond of glucose promoted by the hydrophobic catalysts will be investigated, and the relationship between kinds of doped-metal and glucose isomerization will be studied, and the in-situ aerobic oxidation methods of glucose to 2,5-diformylfuran will be built. It has significance of science and banausic prospects that the research of design and preparation of novel isomerization-dehydration-oxidation multifunctional catalytic materials to realize the process of highly efficient conversion of glucose to 2,5-diformylfuran, and offering references for other biomass-
