USE - Preparation of highly ordered mesoporous graphene material, which is useful in drug-loading, waste water treatment and energy storage. ADVANTAGE - The method enables preparation of highly ordered mesoporous graphene material in simple and economical manner with different diameter and shape. DETAILED DESCRIPTION - The preparation method of highly ordered mesoporous graphene material, involves performing high-temperature cracking of oleic acid precursor nanoparticles of iron under the action of high boiling solvent to obtain iron oxide nanoparticles coated with oleic acid molecule, dissolving nanoparticles in n-hexane, distilling off n-hexane to obtain highly ordered nanoparticle array structure, calcining highly ordered nanoparticle array structure with nitrogen or argon gas at 300 degrees C for carbonization of oleic acid molecule on surface to obtain nanoparticles with carbon layer coating, acid etching to obtain mesoporous carbon material having high specific surface area, and performing graphitization of mesoporous carbon material. The high-boiling solvent is hexadecene, octyl ether, octadecene or eicosene, and acid used for acid etching is hydrochloric acid, sulfuric acid or nitric acid.
