The atomistic origin of the extraordinary oxygen reduction activity of Pt(3)Ni(7) fuel cell catalysts

Recently Debe et al. reported that Pt(3)Ni(7) leads to extraordinary Oxygen Reduction Reaction (ORR) activity. However, several reports show that hardly any Ni remains in the layers of the catalysts close to the surface (“Pt-skin effect”). This paradox that Ni is essential to the high catalytic acti...
