The surface acidity of the catalyst was determined using FTIR spectroscopy employing pyridine as a molecular probe. The Nb2O5 center dot nH(2)O@Re-Cellulose catalyst was investigated in the conversion of glucose into 5-hydroxymethylfurfural (HMF) in aqueous media. The catalyst can be reused several times without undergoing a significant loss in activity.Chemistry, PhysicalChemistrysustainable chemistryheterogeneous catalysisregenerated celluloseniobium pentoxideglucose5-hydroxymethylfurfural (hmf)catalytic dehydrationenhanced formationdirect conversionacidsilicaoxidephosphateoxidationzeolitebiomasstext::journal::journal article::research article
