The effect of size on the oxygen electroreduction activity of mass-selected platinum nanoparticles

A matter of size: The particle size effect on the activity of the oxygen reduction reaction of size-selected platinum clusters was studied. The ORR activity decreased with decreasing Pt nanoparticle size, corresponding to a decrease in the fraction of terraces on the surfaces of the Pt nanoparticles (j(k) =kinetic current density, see picture).
