    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: The present invention is related to a mesoporous carbon molecular sieve, which can be used as a catalyst carrier capable of improving the activity of a supported catalyst and a method of preparing the same. Additionally, the invention is related to a supported catalyst employing the mesoporous carbon molecular sieve as a carrier, and a fuel cell employing the supported catalyst. The mesoporous carbon molecular sieve has an average primary particle size of less than about 500 nm, an average mesopore size in the range of about 3 nm to about 6 nm, and a surface area in the range of about 500 m2/g to about 2000 m2/g.

    摘要: A hierarchical mesoporous carbon is provided in which a total volume of mesopores of the hierarchical mesoporous carbon is 80% or greater of a total volume of pores of the hierarchical mesoporous carbon; a volume of mesopores with a average diameter greater than 20 nm and no greater than 50 nm is 3% or greater of the total volume of the pores; and a volume of mesopores with a average diameter greater than 2 nm and no greater than 10 nm is 65% or greater of the total volume of the pores. The hierarchical mesoporous carbon, which also contains macropores, has an optimized mesoporous distribution characteristic, and has an increased total volume of pores, thereby having a significantly improved catalytic activity when used as a catalyst support. When such a supported catalyst is used in a fuel cell, supply of fuel and transporting of byproducts are facilitated.
