Abstract

Abstract : A new strategy, optimising the work function via the doping of foreign metals, is revealed to enhance the oxygen reduction reactivity on TiN surface. Abstract : Oxide layers on conductive TiN have recently been investigated to catalyse the oxygen reduction reaction (ORR) in acidic media. The ORR reactivity, i.e., activity and selectivity, has been correlated with the surface nitrogen atoms. A new strategy, optimising the work function via the doping of foreign metals, is revealed herein to enhance the reactivity.
