Described herein are bimetallic nanoframes and methods for producing bimetallic nanoframes. A method may include providing a solution including a plurality of nanoparticles dispersed in a solvent, and exposing the solution to oxygen to convert the plurality of nanoparticles into a plurality of nanoframes.

Nanoframes with three-dimensional electrocatalytic surfaces

A multimetallic core/interlayer/shell nanoparticle comprises an inner core formed from a first metal. An interlayer is disposed on the first layer. The interlayer includes a plurality of gold atoms. An outer shell is disposed over the interlayer. The outer shell includes platinum and the first metal. A surface of the NP is substantially free of gold. The first metal is selected from the group consisting of nickel, titanium, chromium, manganese, iron, cobalt, copper, vanadium, yttrium, ruthenium, palladium, scandium, tin, lead and zinc.

Multimetallic core/interlayer/shell nanoparticles

A surface segregated bimetallic composition of the formula RuIrwherein 0.1&#x2266;x&#x2266;0.75, wherein a surface of the material has an Ir concentration that is greater than an Ir concentration of the material as a whole is provided. The surface segregated material may be produced by a method including heating a bimetallic composition of the formula RuIr, wherein 0.1&#x2266;x&#x2266;0.75, at a first temperature in a reducing environment, and heating the composition at a second temperature in an oxidizing environment. The surface segregated material may be utilized in electrochemical devices.
