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.

通过不同方法设计合成了一系列氧化铁修饰的负载在还原氧化石墨烯（rGO）上的铂纳米粒子，并尝试作为甘油的好氧氧化催化剂。发现这些基于Pt的催化剂的固有活性强烈取决于Pt纳米颗粒的电子富集。具有适当的Fe / Pt比率的Pt-Fe ₃ O ₄ / rGO催化剂提供了最富电子的Pt纳米颗粒，并且由于Pt和Fe氧化物之间的强协同作用而提供了优异的催化活性。在Pt-Fe ₃ O ₄ / rGO（Fe / Pt摩尔比为8.5）上，甘油氧化的周转频率高达5931 h ^-1，是在Pt / rGO上的甘油氧化的周转频率的3倍。
