Title: Photocatalytic methods for preparation of electrocatalyst materials

Abstract

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 polymer electrolyte membrane fuel cells (PEM-FCs).
