TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Method: The impregnated OMS is irradiated with microwave energy for 1-180 minutes. Carbonizing the impregnated OMS is performed under a non-oxidizing atmosphere. The method comprises heat-treating the impregnated OMS at 50-250degreesC, before carbonizing the impregnated OMS. Impregnating the OMS with the carbon precursor mixture is carried out by impregnating the OMS with a first portion of the carbon precursor mixture, heat-treating the OMS impregnated with the first portion of the carbon precursor mixture at 50-250degreesC, and carrying out an additional cycle(s), where OMS is impregnated with additional portion of the carbon precursor and then heat treated. The mesoporous silica is removed by dissolving the mesoporous silica with an aqueous hydrofluoric acid solution or an aqueous sodium hydroxide solution. Preferred Component: The acid is from sulfuric acid, nitric acid, phosphoric acid, and/or p-toluene sulfonic acid. The OMS has a cubic structure, a hexagonal structure, or an irregular, three-dimensional structure. It is MCM-48, SBA-1, SBA-15, KIT-1, or MSU-1. Preferred Parameter: The mesoporous carbon has an average diameter of mesopores of 2-10 nm, a specific surface area of 300-2000 m2/g, and a sheet resistance of 20-200 mOmega/cm2 at 75.4 kgf/cm2. A main peak appears in 2theta between 0.5-20degrees at copper potassium (CuK)-alpha characteristic x-ray wavelength of 1.541 A?. Preferred Composition: The metal catalyst particles impregnated in the supported catalyst is 40-80 pbw, based on 100 pbw of the supported catalyst.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Component: The carbon precursor is from carbohydrates, furfuryl alcohol, divinylbenzene, phenolformaldehyde, resorcinol-formaldehyde, phenanthrene, and/or anthracene. The solvent is from water, acetone, methanol, ethanol, isopropylalcohol, n-propylalcohol, butanol, dimethylacetamide, dimethylformamide, dimethylsulfoxide, N-methyl-2-pyrrolidone, tetrahydrofuran, tetrabutylacetate, n-butylacetate, m-cresol, toluene, ethyleneglycol, gamma-butyrolactone, and/or hexafluoroisopropanol. Preferred Composition: Carbon precursor is 5-15 pbw, based on 100 pbw of the carbon precursor mixture. The acid is 10-35 pbw, based on 100 pbw of the carbon precursor mixture. The solvent is 55-80 pbw, based on 100 pbw of carbon precursor mixture. EXAMPLE - Sucrose (2.3 g) and sulfuric acid (0.25 g) were completely dissolved in water (6.6 ml) to prepare a homogeneous carbon precursor mixture. The carbon precursor mixture was divided into two parts in a weight ratio of 60:40. SBA-15 (1 g) was impregnated with the larger solution. The impregnated SBA-15 was dried at room temperature for 30 minutes, and then dried at 160degreesC for 2 hours. The dried result was impregnated with the remaining solution, and dried in the same manner as above. The dried sample was cooled to room temperature, and then irradiated with microwave energy having a power of 570 W under a nitrogen atmosphere for 1 hour to heat to 900degreesC, performing carbonization. The carbonized material was added to a mixed solution of HF, water, and ethanol and then stirred. The adding and stirring processes were repeated to remove SBA-15, leaving behind a mesoporous carbon material having a surface area of 1846 m2/g, pore volume of 2.09 cm3/g, and pore diameter of 3.8 nm.
