Face-centered tetragonal (fct) FePt nanoparticles on graphene nanosheets (fct-FePt/G) were successfully fabricated by one-pot hydrothermal synthesis and followed by heat treatment. The characterizations were examined by X-ray diffraction (XRD), vibrating- ample magnetometer (VSM), transmission electron microscopy (TEM), and lectrochemical measurements. The oxygen reduction reaction (ORR) results indicate higher specific activity (~2 times) and mass activity (~12 times) of fctFePt/G catalysts compared with commercial Pt black. The fct-FePt/G catalysts demonstrated superior electrochemical properties may due to the spin-orbit coupling between Fe (3d) and Pt (5d) which improves the Pt electrochemical activity. Also, the cooperation of graphene as the substrate would enhance the oxygen reduction reaction (ORR) due to the geometric and electronic effect between graphene and FePt nanoparticles.
