High-quality bimetallic Pt_xCu_100-x (x=54-80 at. %) nanocubes can be prepared from a hot organic solution. Synthetic conditions, such as the ratio of oleylamine/tetraoctylammonium bromide as well as the doses of 1-dodecanethiol and 1,2-tetradecanediol have been optimized to ensure a formation of Pt—Cu nanocubes. Electrochemical evaluation shows that the catalytic activity of Pt₆₀Cu₄₀ nanocubes for methanol oxidation is superior, in comparison with those of spherical Pt₆₀Cu₄₀ nanocubes and Pt nanocubes with similar sizes, implying that the {100}-terminated Pt₆₀Cu₄₀ nanocubes offer a higher activity for methanol oxidation reaction than those with mixed crystallographic facets do. As another example, it was identified that Pt₈₀Cu₂₀ nanocubes is the best electrocatalyst on the basis of the maintainable electrocatalytic activity (which is even slightly superior to that of pure Pt nanocubes) and remarkable long-term stability (˜300 hours vs 3 hours for Pt nanocubes) when being performed towards formic acid oxidation reaction.
