Patent ID: 7854913

Claim:
A method of preparing an ordered mesoporous carbon, the method comprising: mixing a carbon precursor, an acid, and a solvent to obtain a carbon precursor mixture, wherein the carbon precursor is at least one material selected from the group consisting of carbohydrates, furfuryl alcohol, divinylbenzene, phenol-formaldehyde, resorcinol-formaldehyde, phenanthrene and anthracene; impregnating an ordered mesoporous silica (OMS) with the carbon precursor mixture; carbonizing the impregnated OMS at 800 to 1300° C. by irradiating the impregnated OMS with microwave energy with a power of 500 to 1180 W to form an OMS-carbon composite; and removing the mesoporous silica from the OMS-carbon composite, wherein the amount of the carbon precursor is 5-15 parts by weight based on 100 parts by weight of the carbon precursor mixture, the amount of the acid is 10-35 parts by weight based on 100 parts by weight of the carbon precursor mixture, and the amount of the solvent is 55-80 parts by weight based on 100 parts by weight of the carbon precursor mixture.
