Abstract
A facile strategy to Pt3Ni nanocrystals with highly porous features is developed. The integration of a high surface area and rich step/edge atoms endows the nanocrystals with an impressive oxygen reduction reaction (ORR) specific activity and mass activity. These nanocrystals are more stable in ORR and show a small activity change after 6000 potential sweeps. This is a promising material for practical electrocatalytic applications.Keywords
