英文摘要： 2,5-Diformylfuran (DFF) has received particular attention due to the various applications in pharmaceuticals, functional polymers and energy-materials etc. This project aims to carry out study on one-pot aproach to DFF from cheap fructose over the novel acid-metal bifunctional catalysts through dehydratic oxidation pathway. The bifunctional catalysts are metalloporphyrin based acidic porous organic polymers. DFF will therefore be produced by the acid (H+)-catalyzed dehydration of fructose, followed by the metalloporphyrin M(Por)-catalyzed aerobic oxidation of 5-hydroxymethylfurfural (HMF). The porous properties such as pore diameters and surface areas of the catalyst will be tuned by the size of linker molecules. The catalytic performance of the bi-functional catalyst on dehydration and oxidation reactions will be tuned by the controllable tuning the acid density and metal content, respectively. The mechanism on dehydration of fructose and oxidation of HMF will be investigated, and highly selective conversion of fructose to DFF will be relalized. The ratio of acid density to the transition metal density (nH+/nM) of the catalyst is used to monitor the balance between the dehydration and oxidation functions in this research, which will provide theoretical guidance for the construction of high efficient bifunctional catalysts. The goal of this project is to enhance understanding of the roles of construction for bifunctional catalytic system, to provide a theoretical basis for the high-value utilization of biomass resource. The research thus has great theoretical significance and potential application values.
