ABSTRACT:
A mesoporous carbon composite includes mesoporous carbon having mesopores; a conductive polymer coated on only an outer surface of the mesoporous carbon; and an organic electrolyte. The mesoporous carbon composite may be prepared by impregnating an ordered mesoporous silica (OMS) with a mixture comprising a carbon precursor, an acid, and a solvent; heat-treating and carbonizing the impregnated OMS to form an OMS-carbon composite; mixing the OMS-carbon composite with a monomer that forms a conductive polymer and a solvent to provide a surface of the OMS-carbon composite with the monomer; polymerizing the monomer to obtain a conductive polymer-coated OMS-carbon composite; removing the OMS from the composite to obtain a conductive polymer-coated mesoporous carbon; and doping the conductive polymer-coated mesoporous carbon with an organic electrolyte. A supported catalyst and a fuel cell include the mesoporous carbon composite.
