Title: Nanosegregated surfaces as catalysts for fuel cells

Abstract

A method of preparing a nanosegregated Pt alloy having enhanced catalytic properties. The method includes providing a sample of Pt and one or more of a transition metal in a substantially inert environment, and annealing the sample in such an environment for a period of time and at a temperature profile to form a nanosegregated Pt alloy having a Pt-skin on a surface. The resulting alloy is characterized by a plurality of compositionally oscillatory atomic layers resulting in an advantageous electronic structure with enhanced catalytic properties.
