Abstract
Official abstract text for this publication.
The invention relates to methods of preparing metal particles on a support material, including platinum-containing nanoparticles on a carbon support. Such materials can be used as electrocatalysts, for example as improved electrocatalysts in proton exchange membrane fuel cells (PEM-FCs).
First claim
Opening claim text (preview).
Having described our invention, we claim: 1. An electrocatalyst, comprising: a support material comprising electron-conducting carbon particles, wherein the carbon particles include an outer surface; and platinum-containing particles formed of reduced platinum evenly dispersed on the outer surface of the carbon particles, the platinum-containing particles having a diameter of between 2 nm and 20 nm and wherein the platinum containing particles chemically bond at an interface with the carbon particles and match the shape of the outer surface of the carbon particles.
