摘要：

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.
