Highly enhanced durability of a graphitic carbon layer decorated PtNi3 alloy electrocatalyst toward oxygen reduction reaction

The durability issue of carbon supported PtNi3 alloy catalyst (PtNi3/C) in acid conditions has been solved by introducing a N-doped graphitic carbon (NGC) layer to coat on 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.
