A series of iron oxides decorated platinum nanoparticles supported on reduced graphene oxide (rGO) were designed and synthesized by different methods, and attempted as catalysts for the aerobic oxidation of glycerol. The intrinsic activities of these Pt-based catalysts were found strongly depended on the electron enrichment of Pt nanoparticles. Pt-Fe3O4/rGO catalyst with appropriate Fe/Pt ratio afforded the most electron-enriched Pt nanoparticles and the superior catalytic activity due to the strong synergistic effect between Pt and Fe oxides. The turnover frequency of glycerol oxidation over Pt-Fe3O4/rGO (with 8.5 Fe/Pt molar ratio) was up to 5931 h(-1), 3 times higher than that of over Pt/rGO.
