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