Abstract
In this paper we compare the catalytic activitites of untouched metal macrocyclic and pyrolyzed catalysts for ORR in acid versusthe formal potential of the catalyst and find in general that the catalysts reported in the literature exhibiting more positive formalpotentials are more active for ORR. These trends observed could serve as a hint for the development more active non-precious metalcatalysts for fuel cells.©2012 The Electrochemical Society.
