Abstract

A method of preparing a mesoporous carbon includes mixing a mesophase pitch, 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; heat-treating and carbonizing the impregnated OMS to form an OMS-carbon composite; and removing the OMS from the OMS-carbon composite. The mesoporous carbon uses the mesophase pitch and the carbon precursor to reduce sheet resistance, and thus can efficiently transfer electric energy. Such mesoporous carbon can be used as a conductive material of electrodes for fuel cells. When the mesoporous carbon is used as a support for catalysts of electrodes, a supported catalyst containing the support can be used to manufacture a fuel cell having high efficiency.
