Title:		Pt-Fe bimetallic electrocatalyst
Inventor:		Albert Kowalak
Summary:		The patented invention relates to electrocatalysts and methods for making electrocatalysts. Many chemical reactions, while thermodynamically favorable, do not occur at useful rates without assistance. For such reactions to be useful, it is often necessary to find a homogeneous or heterogeneous catalyst that will increase the rate of reaction, often by several orders of magnitude. A particular type of catalyst known as an electrocatalyst provides low energy activation pathways that permit electricity-producing reactions to occur at a practical rate. The invention is based on the discovery that a lightweight, economical, highly active platinum-based electrocatalyst can be obtained if platinum oxides and iron oxides are combined to form Pt/Fe particles in a colloidal solution. A Pt/Fe/C electrocatalyst for example, the oxidation of methanol in fuel cells, Pt/Fe colloidal particles and a method for preparing the Pt/Fe/C electrocatalyst are described.
