Two-phase synthesis of pt-surface of nanostar

Abstract

Disclosed is a method for preparing an alloy nanostar, the method including a nanostar synthesis process including combining a first metallic precursor component, a second metallic precursor component, and solvent to provide a first solution, combining the first solution with a third metallic precursor component to provide a second solution, maintaining the second solution at a first selected temperature for a first selected period of time such that an oil-water two phase suspension is formed, and heating the oil-water two phase suspension to a second selected temperature for a second selected period of time sufficient to provide an alloy nanostar. Also described are alloy nanostars having an alloy of at least a first metallic element and a second metallic element, wherein the second metallic element is platinum.
