When the Sabatier Principle and the ORR activity volcano curve are applied to ORR on Au(100), it is reasoned that the weak interactions between oxygenated species and Au surface embodying an ORR mechanism distinct from that on Pt. Lower adsorption energies, away from the narrow center of the ORR volcano curve, could actually be an advantage, if the challenge to facilitate O2 adsorption onto the electrode surface could be met.
