Abstract

The carbon-supported 30Pt-10Au/C composite nanoparticles (NPs) catalysts with Au NPs of three different sizes were synthesized by the successive reduction of HAuCl₄ and H₂PtCl₆ precursors. The size effect of the Au NPs on the electrocatalytic activity of the 30Pt-10Au/C catalysts for methanol oxidation was examined by cyclic voltammetry in a 1 M H₂SO₄ and 1 M CH₃OH aqueous solution. The Au NPs improved the catalytic activity of Pt NPs for methanol oxidation based on the bi-functional catalytic mechanism, and this effect of Au NPs accelerated remarkably with decreasing Au NP size.
