    摘要: 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.

    摘要: A method of preparing a supported catalyst, the method comprising mixing a first catalytic metal precursor and a first solvent to obtain a first catalytic metal precursor mixture; mixing a carbon support for catalyst and the first catalytic metal precursor mixture, and drying the mixture to obtain a primary supported catalyst precursor; subjecting the primary supported catalyst precursor to a hydrogen reduction heat treatment, to obtain a primary supported catalyst; mixing the primary supported catalyst and a polyhydric alcohol to obtain a primary supported catalyst mixture; mixing a second catalytic metal precursor and a second solvent to obtain a second catalytic metal precursor mixture; mixing the primary supported catalyst mixture and the second catalytic metal precursor mixture to obtain a secondary supported catalyst precursor mixture; and adjusting the pH of the secondary supported catalyst precursor mixture, and then heating the secondary supported catalyst precursor mixture to obtain a supported catalyst, a supported catalyst prepared by the method, an electrode comprising the supported catalyst, and a fuel cell including the electrode are provided. A supported catalyst having a desired amount of loaded catalytic metal particles can be obtained by preparing a primary supported catalyst containing catalytic metal particles that are obtained by a primary gas phase reduction reaction of a portion of the final loading amount of catalytic metal, and reducing the remaining portion of the catalytic metal by a secondary liquid phase reduction reaction. The supported catalyst contains catalytic metal particles having a very small average particle size, which are uniformly distributed on a carbon support at a high concentration, and thus exhibits maximal catalyst activity. A fuel cell produced using the supported catalyst has improved efficiency.
