TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The acid is at least one acid selected from sulfuric acid, nitric acid or phosphoric acid.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preparation (claimed): Preparation of the sulfur-containing mesoporous carbon involves mixing a sulfur-containing carbon source, an acid, and a solvent to obtain a sulfur-containing carbon source mixture; impregnating an ordered mesoporous silica (OMS) with the sulfur-containing carbon source mixture; drying and heat-treating the impregnated OMS; carbonizing the resulting product; and removing the OMS from the carbonized product. Preferred Method: In the method, the amount of the acid is 5-400 pbw and the solvent is 100-500 pbw, based on 100 pbw of the sulfur-containing carbon source. Preferred Compound: The sulfur-containing mesoporous carbon comprises sulfur (0.1- 20 parts by weight (pbw)). The average diameter of the mesopores is 3-6 nm. A full width at half maximum (FWHM) of a main peak of the mesoporous carbon, obtained by a pore size distribution using nitrogen absorption properties, is less than or equal to 5 nm. A main peak of a Bragg 2 theta angle for a CuK- alpha characteristic X-ray wavelength of 1.541 Angstrom appears at least 0.5-1.5 degrees . The mesoporous carbon has a Brunauer, Emmett, and Teller (BET) surface area of 200-2000 m2/g and a sheet resistance of 10-300 m Omega /cm2 at 150.8 plus minus 3 kgf/cm2. Preferred Catalyst: The supported catalyst comprises the metal catalyst particles (20-90 pbw). In the catalyst, if the metal catalyst particles are heat treated, an increase of an average diameter of the metal catalyst particles after heat treatment with respect to an average diameter of the metal catalyst particles before heat treatment is less than or equal to 20%. Preferred Components: The sulfur-containing carbon source includes at least one material selected from furfuryl mercaptan, mixture of furfuryl mercaptan and furfuryl alcohol, monobenzothiophene, dibenzothiophene, p-polyphenylene sulfide, or para-toluenesulfonic acid. The solvent is at least one material selected from water, acetone, methanol, ethanol, isopropylalcohol, n-propylalcohol, butanol, dimethylacetamide, dimethylformamide, dimethylsulfoxide, N-methyl-2-pyrrolidone, tetrahydrofurane, tetrabutylacetate, n-butylacetate, m-crezole, toluene, ethyleneglycol, gamma -butyrolactone, or hexafluoroisopropanol. The acid is para-toluene sulfuric acid. EXAMPLE - Furfuryl mercaptan (5 g), sulfuric acid (0.125 g) and ethanol (2.5 g) were mixed to prepare a homogeneous sulfur-containing carbon source mixture. The sulfur-containing carbon source mixture (1.65 g) was impregnated with of an ordered mesoporous silica (OMS) (1.5 g). The impregnated OMS was dried in an oven at 100 degrees C for 6 hours, and then, further dried at 160 degrees C for 6 hours. The dried OMS was impregnated with the remaining sulfur-containing carbon source mixture and dried in an oven at 200 degrees C for 2 hours. The dried sample was cooled to room temperature and then carbonized at 900 degrees C under a nitrogen atmosphere. The resulting product was added to a mixed solution of hydrogen fluoride (HF), water and ethanol and then stirred. The adding and stirring processes were repeated to remove the OMS and to obtained a sulfur-containing mesoporous carbon.
