摘要

•We succeeded in fabricating a surface Ru enriched structurally ordered intermetallic PtFe@PtRuFe nanostructure.•We found that the atomic radius of Fe and Ru is a highly decisive factor for the surface composition of the PtFe@PtRuFe.•The well-Constructed PtFe@PtRuFe catalyst exhibits excellent anti-CO poisoning ability and MOR catalytic activity.
