Abstract

The durability issue of a carbon supported PtNi₃ alloy catalyst (PtNi₃/C) under acidic conditions has been solved by introducing an N-doped graphitic carbon (NGC) layer to coat the surface of the PtNi₃/C catalyst. The as-prepared PtNi₃/C@NGC catalyst exhibits superior durability, being able to undergo 10 000 voltage cycles with negligible activity decay.
