- Abstract
Electrocatalyst 57FePt@Pt/C is prepared using two‐step electron beam (e‐beam) irradiation. The formation of a core–shell‐structured 57FePt@Pt/C catalyst is measured using X‐ray diffraction, transmission electron microscopy, energy‐dispersive spectroscopy, and Mössbauer spectroscopy. Both fast reaction and simple process of e‐beam irradiation are suitable application of mass production. In addition, the electrochemical performance of the 57FePt@Pt/C catalyst after acid washing is observed to be the same as the activity of the commercial Pt/C during oxygen reduction reaction, while minimizing Pt supplement.
