DFT calculation results of optimized Pt atoms in Pt17 on graphite, describing the interaction of oxygen with each Pt atom, shown with atom index.

Caption

The origin of high ORR activity of (a) Pt17/CB can be attributed to: (b) variable electric charges of each Pt atom on the nanocluster, (c) represented intermediate structure optimized for O2/Pt17/graphite and (d) intermediate structure optimized for (O + OH)/Pt17/graphite.
