The Enhanced-electrocatalytic Activity of Ni@Pd Core-shell Nanoparticles Supported on Reduced-graphene Oxide Nanosheets for Hydrazine Oxidation

以PVP模版法合成了Ni@Pd/r GO催化剂,将核壳结构的双金属纳米粒子负载在氧化石墨烯上,通过TEM、XRD、FT-IR、Raman等测试对催化剂结构进行了表征,结果显示:合金纳米粒子在石墨烯上具有很好的分散性。通过联氨氧化实验结果表明:Ni@Pd/r GO催化剂在联氨燃料电池中具有很高的电催化活性。

we synthesize the Ni@ Pd/rGO catalyst by loading Ni@ Pd core-shell nanoparticles on the sur- face of the graphene oxide using PVP as template. The catalyst is characterized by TEM, XRD, FT-IR and Raman. The results indicate that alloy nanoparticles have good dispersion in graphene oxide. The Ni@ Pd/rGO catalyst shows high enhanced-electroeatalvtic activity forhydrazine oxidation.
