Abstract
Pt Fe/C/N-GC electrocatalysts were prepared using a composite of Hofmann-like Pt/Fe-based metal-organic frameworks and two-dimensional oxidized graphene. The Pt Fe/C/N-GC-700 composite (annealed at 700 °C) exhibited an enhanced mass activity in the electrocatalytic methanol oxidation reaction, which was ten times higher than that of commercial Pt/C (20%) catalysts.
摘要
采用类霍夫曼型铂/铁基金属有机骨架与二维氧化石墨烯的复合材料制备了铂铁/碳/氮-石墨烯（Pt Fe/C/N-GC）电催化剂。铂铁/碳/氮-石墨烯-700复合材料（在700℃退火）在电催化甲醇氧化反应中表现出增强的质量活性，比商业铂/碳（20%）催化剂高十倍。
