TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The carbon precursor is carbohydrate chosen from monosaccharides and/or small saccharides. The carrier is chosen from water and/or organic solvent such as an alcohol (especially ethanol). The mixture further contains an acid.    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Mold: The template is MCM-48, KIT-1, MSU-1, SBA-1, SBA-3, SBA-15 and SBA-16.Preferred Acid: The acid is chosen from sulfuric acid, hydrochloric acid, nitric acid and/or sulfonic acid.Preferred Solution: The solution for dissolving silica is hydrogen fluoride aqueous solution or sodium hydroxide aqueous solution.Preferred Properties: The silica oligomer has average particle size of 0.5-5 nm. The template has more than 1 cm3/g of air holes with size of 80 nm or less.Preferred Process: Mixture (A) of carbon precursor and liquid carrier is impregnated in the fine air holes of template having intermediate size air holes and fine air holes. The precursor is polymerized and mixture (B) containing silica oligomer, carbon precursor and liquid carrier is impregnated in the intermediate size air holes and the carbon precursor is polymerized. The polymer is thermally decomposed and carbonized. The template is processed with solution which selectively dissolves silica and the silica oligomer is removed.Preferred Conditions: The template impregnated with the mixture is subjected to primary heat-processing at 50-150degreesC and secondary heat-processing at 150-250degreesC. The template containing carbon precursor polymer is heat-processed at 400-1400degreesC in non-oxidizing atmosphere such as vacuum atmosphere, nitrogen atmosphere and inert gas atmosphere. EXAMPLE - Sucrose (in g) (0.94), distilled water (3.75) and sulfuric acid aqueous solution (0.11) were mixed and solution (A) was produced. Tetraethyl orthosilicate (0.63), ethanol (0.63) and hydrochloric acid aqueous solution (0.21) were mixed to obtain solution (B) containing silica oligomer with average particle size of 0.8 nm. The mixture of the solutions (A, B) was impregnated on template (SBA-15). The impregnated template was dried at 100degreesC for 6 hours and heat-processed at 160degreesC for 6 hours. The impregnation and the dry heat processing were repeated and the template was heat-processed at 900degreesC for 2 hours in nitrogen atmosphere. The heat-processed template was immersed in a mixed solution of hydrogen fluoride, water and ethanol and stirred at normal temperature for 2 hours. The template was filtered, washed and dried at 100degreesC for 12 hours to obtain carbon molecular material with favorable porosity.
