Abstract

We have developed “crack–tips” and “superlattice” enriched Pt–Cu nanoflakes (NFs), benefiting from the synergetic effects of “crack–tips” and “superlattice crystals”; the Pt–Cu NFs exhibit 4 times higher mass activity, 6 times higher specific activity and 6 times higher stability than those of the commercial Pt/C catalyst, respectively. Meanwhile, the Pt–Cu NFs show more enhanced CO tolerance than the commercial Pt/C catalyst.
