As demonstrated by Nørskov et al. , catalysts that bind oxygen slightly more weakly than Pt can enhance catalytic activity. Such catalysts would reduce the site-blocking oxygen coverage θ O (U ) at given potentials and potentially lower the activation energy through more favorable reaction thermodynamics. However, our work suggests that designing oxidationresistant catalysts may be a more effective strategy. This approach could shift the sharp oxidation transition occurring at 1.05 V in this work, close to the onset potential of the ORR, toward higher potentials while maintaining a reactive oxygen coverage, thereby reducing the site-blocking coefficient at high potentials and ultimately enhancing catalytic activity.
