英文摘要：

5-hydroxymethylfurfural,as one of the important biomass based platform molecules,is taken as a bridge between biomass and high-valued chemicals,which can be directly synthesized from carbohydrate via catalyzed dehydration.How to selectively reconstructed the C-O bond is the core issue for the high-valued utilization of5-hydroxymethylfurfural.In the past decade,the investigations about the conversion of5-hydroxymethylfurfural to biofuels and materials have experienced rapid growth.Innovative catalysts and catalytic systems are applied into the synthesis and conversion of5-hydroxymethylfurfural.In this paper,the preparation of5-hydroxymethylfurfural and its conversion to bio-fuels and materials are summarized and prospected.
