Abstract

An electrode catalyst for an Oxygen Reduction Reaction (ORR) is provided that includes a transition metal nitride layer on a substrate, an ORR surface oxide layer deposited on the transition metal nitride layer, where the ORR surface oxide layer includes from sub-monolayer to 20 surface oxide monolayers.
