Abstract:Subnano-MoO3 clusters (below 1 nm) have excellent catalytic activity on oxidative desulfurization (ODS). However, the stability is not very satisfactory due to the leaching of MoO3 during the reaction. To enhance the stability, here we developed a method by grafting NH2 to silica. NH2 could form coordination bond with MoO3, as proved by solid state H-1 NMR, which can prevent MoO3 from leaching and thus significantly enhance the stability.
