Facile synthesis of ternary PtPdCu alloy hexapods as highly efficient electrocatalysts for methanol oxidation.

ABSTRACT: Developing an efficient Pt-based multimetallic electrocatalyst with well-defined shapes for methanol oxidation reaction (MOR) is critical, however, it still remains challenging. Here we report a one-pot approach for the synthesis of ternary PtPdCu alloy hexapods with different compositions. Their MOR activities increased in the sequence Pt₂PdCu₄ < Pt₃PdCu₄ < Pt₅PdCu₅, and were substantially higher than that of commercial Pt/C. Specifically, the Pt₅PdCu₅ hexapods exhibited the highest mass (0.97 mA μg_Pt ^-1) and specific (7.39 mA cm^-2) activities towards MOR, and were 5.4 and 19.4 times higher than those of commercial Pt/C (0.18 mA μg_Pt ^-1 and 0.38 mA
