Crack–tips enriched platinum–copper superlattice nanoflakes as highly efficient anode electrocatalysts for direct methanol fuel cells

Author affiliations

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.
