摘要

•Pt shell is fabricated by galvanic replacement reaction of Cu by Pt.•The thickness of Pt shell is controlled by the different composition of Pd and Cu.•(Pd,Cu)@Pt/C catalysts show higher oxygen reduction reaction activity than that of PtPdCu/C.•Pd2Cu1@Pt/C catalyst exhibits superior long-term durability.
