Abstract

High-quality Pt-Cu nanocubes were prepared through simultaneous reduction of platinum (II) acetylacetonate and copper II) acetylacetonate in 1-octadecene by 1,2–tetradecanediol in the presence of tetraoctylammonium bromide, oleylamine, and 1-dodecanethiol. The growth process of Pt-Cu nanocubes was explored based on the observation of intermediates. The electrocatalytic behavior indicates that cubic Pt-Cu nanocrystals are more active than spherical Pt-Cu nanocrystals and Pt nanocrystals towards methanol oxidation reaction.
