Description:
Surface evolution of a Pt–Pd–Au electrocatalyst for stable oxygen reduction Nature Energy, Published online: 10 July 2017; doi:10.1038/nenergy.2017.111 Metal alloys possessing core–shell structures have potential as low-Pt catalysts for the oxygen reduction reaction in fuel cells, but can suffer from poor stability. Using high-resolution microscopy, Li et al. find that a Pt–Pd–Au catalyst undergoes surface atomic rearrangement and becomes more active on electrochemical cycling.
