Abstract

Abstract : An N-doped graphitic carbon layer was for the first time introduced to greatly enhance the durability of a PtNi3 /C alloy catalyst in an acidic environment. 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.
