Abstract
The present invention provides a method of producing ternary metal-based nanowire networks. The method comprises combining an aqueous mixture of a platinum hydrate, a ruthenium hydrate, and an iron hydrate with a solution of hexadecyltrimethylammonium bromide in chloroform to form an inverse micellar network; adding a reducing agent to reduce metal ions within the inverse micellar network; and isolating the nanowires. The relative amounts of the platinum, ruthenium and iron in the mixture correlate to the atomic ratio of the platinum, ruthenium and iron in the ternary nanowires. The diameters of the ternary nanowires are from about 0.5 nm to about 5 nm.
