Abstract

A novel dendritic titanium oxynitride (TiN_xO_y) nanostructure composed of nanowires of 15–20 nm in diameter has been prepared. The dendritic TiN_xO_y nanostructure nitrided at 900 °C possesses high electrocatalytic activity for ORR with a four-electron process, high onset potential of −0.13 V, and superior durability compared with the commercial 10% Pt/C catalyst.
