TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Parameters: The mesoporous carbon is a replica of mesoporous silica manufactured by high temperature microwave method and which has space group of Ia3d. The weight ratio of sucrose and mesoporous silica is greater than or equal to 0.75 (preferably 0.75-1). The surfactant P123, n-butanol, water, acid and tetraethoxysilane are mixed by molar ratio of 1.7-3:1.31x 102-2.22x 102:19.5x 103-27.5x 103:1.83x 102-2.75x 102:1x 102-2.4x 102 (preferably 1.7:1.31x 102:19.5x 103:1.83x 102:1x 102). Preferred Process: The polymerization is carried out by heating at 8x 101 to 10x 101 degrees C for 4-6 hours. The mixture is further polymerized by heating at 14x 101 to 16x 101 degrees C for 4-6 hours. The polymerization may be carried out by adding sucrose, acid and water to mixture, heating at 8x 101 to 10x 101 degrees C for 4-6 hours, and further heating at 14x 101 to 16x 101 degrees C for 4-6 hours. The carbonization is carried out by heating polymer at 6x 102 to 9x 102 degrees C in nitrogen atmosphere for 4-6 hours. The remaining silica is removed by dissolving carbonized material in hydrofluoric acid, and washing by ethanol. The high temperature microwave method involves mixing surfactant P123, n-butanol, water, acid and tetraethoxysilane; heating obtained mixture and polymerizing tetraethoxysilane; irradiating microwave to obtained polymer while heating to obtain silicide; heating obtained silicide; and removing remaining surfactant P123. The polymerization in high temperature microwave method is carried out by stirring at 35 degrees C for 24 hours. The microwave is irradiated at 1x 102 to 2.5x 102 degrees C for one half to 2 hours. The remaining surfactant is removed by filtering silicide, drying, and heating at 5.4x 10-2 degrees C for 24 hours. Preferred Components: The acid is p-toluenesulfonic acid, nitric acid, phosphoric acid or sulfuric acid. The acid used in high temperature microwave method is hydrochloric acid, sulfuric acid or nitric acid.
