Abstract
A composition comprising particulate carbonaceous material and a conducting polymer containing hetero atoms. The composition can further comprise a metal. Devices comprising the composition can be constructed including supported electrocatalysts, membrane electrode assemblies, and fuel cells. A method for preparing the composition comprises oxidatively polymerizing a monomer of a conducting polymer containing hetero atoms in the presence of a carbonaceous material wherein the oxidative polymerization takes place in the presence of a metal-containing oxidizing agent. The method grafts the conducting polymer to the carbonaceous material while essentially simultaneously metallizing the composition.
