We reported the design of a core-shell Cu@PtCu electrocatalyst consisting of dendritic PtCu alloy branches assembling on Cu core nanocrystals. The Cu@PtCu electrocatalyst shows superior electrocatalytic performance toward a methanol oxidation reaction. Its specific activity and mass activity can reach 3.56 mA cm(-2) and 1568 mA mg(Pt)(-1), which are 4.8 and 7.1 times higher than those of a commercial 20% Pt/C catalyst.
