Solid acids catalysts based on niobium oxide incorporated on different supports (commercial fumed silica and γ-Al2O3, MCM-41 and SBA-15 silicas) have been synthesized, characterized by using XRD, N2 sorption at −196 °C, XPS, Raman spectroscopy, NH3-TPD and pyridine adsorption coupled to FTIR spectroscopy, and tested for the dehydration of d-xylose to furfural. A monophasic water and biphasic water/toluene systems were compared, obtaining similar xylose dehydration activity but improving considerably the furfural selectivity when the toluene was employed as co-solvent. The γ-Al2O3 support enhanced apparently the secondary reactions, as can be inferred for the lower furfural selectivity of the Al-12Nb catalyst compared with the silica support...
