The performance and stability of the oxygen reduction reaction on Pt-M (M = Pd, Ag and Au) nanorods: an experimental and computational study.

The ORR activity of Pt3M NRs is related to the oxophilicity (ΔE(ads)). However, their segregation energy when exposed to oxygen containing species (OCS*) determines their stability. Although the ΔE(ads) of Ag is not as weak as that of Au, its structure is relatively stable, thus promoting the ORR stability.
