One-pot synthesis of Pd@Pt3Ni core-shell nanobranches with ultrathin Pt3Ni{111} skins for efficient ethanol electrooxidation.

Coating an ultrathin platinum-rich skin on nanosubstrates made of other cheaper metals is an effective strategy for fabricating active electrocatalysts with low Pt-content. We developed a facile one-pot synthesis of Pd@Pt3Ni core-shell nanobranches with ultrathin Pt3Ni{111} skins that have active and durable catalytic performances for ethanol electrooxidation.
