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.

Ultrathin, ternary alloy PtRuFe nanowires, and methods of making same

Provided herein is a nanostructure refined by suspending an unrefined nanostructure with a solvent, dispersing the suspended nanostructure in an acidic solution and agitating the acidic solution to produce a refined nanostructure.

Nanostructures having enhanced catalytic performance and method for preparing same

The present invention includes a method of producing a segmented 1D nanostructure. The method includes providing a vessel containing a template wherein on one side of the template is a first metal reagent solution and on the other side of the template is a reducing agent solution, wherein the template comprises at least one pore; allowing a first segment of a 1D nanostructure to grow within a pore of the template until a desired length is reached; replacing the first metal reagent solution with a second metal reagent solution; allowing a second segment of a 1D nanostructure to grow from the first segment until a desired length is reached, wherein a segmented 1D nanostructure is produced.

Segmented metallic nanostructures, homogeneous metallic nanostructures and methods for producing same

A method of synthesizing activated electrocatalyst, preferably having a morphology of a nanostructure, is disclosed. The method includes safely and efficiently removing surfactants and capping agents from the surface of the metal structures. With regard to metal nanoparticles, the method includes synthesis of nanoparticle(s) in polar or non-polar solution with surfactants or capping agents and subsequent activation by CO-adsorption-induced surfactant/capping agent desorption and electrochemical oxidation. The method produces activated macroparticle or nanoparticle electrocatalysts without damaging the surface of the electrocatalyst that includes breaking, increasing particle thickness or increasing the number of low coordination sites.

Method for removing strongly adsorbed surfactants and capping agents from metal to facilitate their catalytic applications

A bimetallic nanowire synthesis method is provided. The method includes adding first and second solutions into a vessel containing a porous template with the first solution containing first and second reagents added on one side of the porous template and the second solution added on an opposite side of the porous template. The first reagent includes a first salt of at least one of a transition metal, an actinide metal and a lanthanide metal. The second reagent includes a second salt of at least one of a transition metal, an actinide metal and a lanthanide metal. The second solution contains a reducing agent.

Surfactantless bimetallic nanostructures and method for synthesizing same

The invention is directed to compositions on a surface which comprise a) at least a (meth)acrylate prepolymer, wherein Q, R, R, R, R, m and n are defined herein. Further the compositions may be used to improve the adhesion to surfaces, especially metallic surfaces and may include additional optional components such as adhesion promoting photoinitiators.
