Synergistic promotion of oxygen vacancy and Lewis acidity of Nb2O5 on the preferential hydroxymethyl hydrogenolysis of 5-hydroxymethylfurfural catalyzed by single atom Pt

Over Pt 1 /Nb 2 O 5 , oxygen vacancy increases the catalytic activity, while the strong Lewis acidity of Nb 2 O 5 selectively promotes the hydrogenolysis of the –CH 2 OH group rather than the hydrogenation of the –CHO group.
