FePt nanoalloys anchored reduced graphene oxide as high-performance electrocatalysts for formic acid and methanol oxidation

Reduced graphene oxide (RGO) supported FePt alloy nanoparticles are synthesized as high-performance electrocatalysts for methanol and formic acid (FA) oxidation. The microstructure, composition and morphology of the sample are systematically characterized with X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), scanning electron microscope (SEM), transmission electron microscope (TEM), energy dispersive spectroscopy (EDS) and Raman spectroscopy. The electrocatalytic tests reveal that, in comparison with pure Pt nanoparticles supported on RGO sheets, the FePt nanoalloys anchored RGO sheets deliver remarkably enhanced electrocatalytic performance on FA/methanol oxidation, improved tolerance to CO poisoning, and superior catalytic durability.
