초록

Here we report an intermetallic Pt5Ce/C oxygen reduction catalyst with intrinsic antioxidant functionality. Under electrochemical conditions, Pt5Ce/C forms Pt-skin surfaces. Subsurface Ce atoms electronically tune Pt-skin to promote H2O2-scavenging, achieving a two-fold faster reaction rate than antioxidant-coupled catalysts. Pt5Ce/C thus delivers excellent catalytic activity and durability for oxygen reduction reaction.
