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 with ozone a monomer of a conducting polymer containing hetero atoms in the presence of a carbonaceous material. The method grafts the conducting polymer to the carbonaceous material. The method can further comprise metallizing the polymer-grafted carbonaceous material.

What is claimed is: 1. A method for preparing a carbon with enhanced electronic conductivity comprising oxidatively polymerizing with an oxidizing agent comprising ozone a monomer of a conducting polymer containing a hetero atom with particulate carbonaceous material to form a conducting polymer-grafted carbonaceous material; and then metallizing the conducting polymer-grafted carbonaceous material. 2. The method of claim 1, wherein the carbonaceous material comprises carbon black, graphite, nanocarbon, fullerene, fullerenic material, finely divided carbon, or a mixture thereof. 3. The method of claim 1, wherein the carbonaceous material comprises carbon black. 4. The method of claim 1, wherein the monomer of a conducting polymer comprises an amino aryl or a nitrogen heterocycle. 5. The method of claim 1, wherein the oxidatively polymerizing comprises adding ozone to a mixture of the carbonaceous material and the monomer of the conducting polymer. 6. The method of claim 5, wherein the mixture of the carbonaceous material and the monomer of the conducting polymer further comprises an acid solvent to form a slightly acidic environment. 7. The method of claim 6, wherein the slightly acidic environment is a pH of about less than 7. 8. The method of claim 6, wherein the slightly acidic environment is a pH of about 3 to about 4. 9. The method of claim 1, wherein the conducting polymer comprises polyaniline, polypyrrole, polyfuran, polythiophene, poly(p-phenylene-oxide), poly(p-phenylene-sulfide), a substituted conducting polymer, or a mixture thereof. 10. The method of claim 1, wherein the metallizing comprises adding a metal-containing material to the conducting polymer-grafted carbonaceous material. 11. The method of claim 10, wherein the metallizing further comprises adding a reducing agent. 12. The method of claim 1, wherein the metallizing comprises platinizing. 13. The method of claim 11, wherein the reducing agent comprises formaldehyde, sodium borohydride, hydrogen, hydrazine, hydroxyl amine, or a mixture thereof. 14. The method of claim 10, wherein the metal-containing material comprises chloroplatinic acid, platinum nitrate, platinum halide, platinum cyanide, platinum sulfide, organoplatinum salt, or a mixture thereof.
