A serial of protonated and layered transition metal oxides, including layered HTa WO_6, HNbMoO_6 as well as HNb WO_6, were synthesized by solid-state reaction and ion-exchange. The layered HTa WO_6 has been systematically studied as a solid acid to realize the dehydration of fructose to 5-hydroxymethylfurfural(HMF). The transition metal oxide samples were characterized with ICP-OES, EDS, XRD, XPS, SEM, TGA,FT-IR, N2adsorption–desorption and NH3-TPD. The influential factors such as reaction temperature, reaction time, solvent, catalyst amount and substrate concentration were deeply investigated. The optimized fructose conversion rate of 99% with HMF yield of 67% were achieved after 30 min at 140 °C in dimethylsulfoxide.
