Nano-Pt Catalysis: Combining the advantages of Fe/NC and Pt catalysts, an in-situ surfactant-free self-templating solution reduction strategy can be applied to construct Pt nanoparticles (NPs) onto well-devised Fe/NC porous nanostructures in order to manufacture highly performing Pt−Fe/NC catalyst for oxygen reduction reaction (ORR). The obtained Pt−Fe/NC catalyst displays excellent ORR performance, realizing an account of 2.53 improvement in specific activity and an account of 1.20 strengthening in mass activity toward ORR compared to the commercial Pt/C catalysts.

将 Pt 纳米粒子工程化到树脂衍生的铁和氮共掺杂多孔碳纳米结构上促进氧还原催化

Nano-Pt 催化:结合 Fe/NC 和 Pt 催化剂的优点,原位无表面活性剂的自模板溶液还原策略可用于在精心设计的 Fe/NC 多孔纳米结构上构建 Pt 纳米粒子 (NPs)制造用于氧还原反应 (ORR) 的高性能 Pt-Fe/NC 催化剂。所获得的 Pt-Fe/NC 催化剂表现出优异的 ORR 性能,与商业 Pt/C 催化剂相比,比活性提高了 2.53,对 ORR 的质量活性提高了 1.20。
