1. An electrode catalyst for an Oxygen Reduction Reaction (ORR), comprising:
a) a transition metal nitride layer deposited on a substrate;
b) an ORR catalyst electrically conductive, partially oxidized surface layer formed on a surface of the transition metal nitride layer, wherein said ORR catalyst electrically conductive, partially oxidized surface layer is at most 20 monolayers thick.
