| 英文摘要 | A series of ordered mesoporous nbxw(8-x) oxides with tunable nb/w ratio were successfully synthesized by evaporation-induced self-assembly method. the mesoporous structure, morphologies, surface chemical state, and acidic properties of these catalysts were fully characterized by low-temperature sorption of n-2, small-angle and wide-angle xrd, tem, raman, xps, and py-ir. it was shown that the nbxw(8-x) oxides created large amounts of lewis as well as brensted acid sites, which promoted the isomerization of glucose to fructose followed its dehydration to 5-hydroxymethylfurfural (hmf). mannose was also. formed via the epimerization of glucose. of them, the mesoporous nb4w4 exhibited the best catalytic activity with a comparatively low ea about 90.2 kj/mol and good stability in aqueous medium. the kinetic behavior revealed that lewis acid sites facilitated to glucose-to-fructose isomerization while brensted acid sites promoted the dehydration of fructose to form hmf.
