ABSTRACT:
A mesoporous carbon is prepared by mixing a carbon precursor, an acid, and a solvent to obtain a carbon precursor mixture; impregnating an ordered mesoporous silica (OMS) with the carbon precursor mixture; carbonizing the impregnated OMS at 800 to 1300° C. by irradiating microwave energy with a power of 100 to 2000 W thereon to form an OMS-carbon composite; and removing the mesoporous silica from the OMS-carbon composite. The method of preparing a mesoporous carbon can significantly reduce a carbonization time by carbonizing a carbon precursor using microwave energy in a silica template compared to a conventional method using a heat treatment. A supported catalyst and a fuel cell include the mesoporous carbon.
