W acts as an electron donor on mixed oxides. That means that many electrons can flow in the conduction band of materials; in this way it became a specific and bifunctional catalyst for the transformation of glucose into 5-HMF and for the hydrolysis of cellulose into glucose. In others words, W location is considered as active site in the catalyst.
I should clear some: W acts as an electron donor on mixed oxides. That means that many electrons can flow in the molecular structure of materials; in this way it became a specific and bifunctional catalyst for the transformation of glucose into 5-HMF and for the hydrolysis of cellulose into glucose. In others words, W location is considered as active acidic-site in the catalyst.
