Aqueous Synthesis of Au₁₀Pt₁ Nanorods Decorated with MnO₂ Nanosheets for the Enhanced Electrocatalytic Oxidation of Methanol.

ABSTRACT: Developing novel catalysts with high activity and high stability for the methanol oxidation reaction (MOR) is of great importance for the ever-broader applications of methanol fuel cells. Herein, we present a facile technique for synthesizing Au₁₀Pt₁@MnO₂ catalysts using a wet chemical method and investigate their catalytic performance for the MOR. Notably, the Au₁₀Pt₁@MnO₂-M composite demonstrated a significantly high peak mass activity of 15.52 A mg(Pt)^-1, which is 35.3, 57.5, and 21.9 times greater than those of the Pt/C (0.44 A mg(Pt)^-1), Pd/C (0.27 A mg(Pt)^-1), and Au₁₀Pt₁ (0.71 A mg(Pt)^-1) catalysts, respectively.
