Dehydration of glucose to 5-Hydroxymethlyfurfural on bifunctional carbon catalysts

The proposed study tries to reply on one important question concerning glucose dehydration: What is the role of bare or tandem Lewis/Brønsted acid sites in the reaction and which are better? A series of mono and bifunctional catalyst are designed and screened for the glucose dehydration reaction. Th...
