Well-defined PtNiCo core–shell nanodendrites with enhanced catalytic performance for methanol oxidation

Abstract

Uniform trimetallic PtNiCo core–shell nanodendrites, composed of a PtNiCo core and dendritic PtCo shell, were synthesized and their enhanced catalytic activities for methanol oxidation can be attributed to the interaction of Pt, Ni, and Co, and their highly ordered dendritic structure.
