Abstract

The Pt@Au catalysts demonstrate remarkably high oxygen reduction reaction (ORR) activity compared with Pt/C catalysts. The ORR of Pt2@Au1/C and Pt1@Au2/C is 9.5 and 6.6 times that of Pt/C, respectively. This improvement is attributed to the electronic structure effect of the Au core on the Pt shell and introduction of PFSA.
