NOVELTY - Coating single-layer ordered mesoporous carbon or graphene by using oxide graphene substrate involves (i) dispersing oxidized graphene in sodium oleate solution, ultrasonically stirring; (ii) adding ferric chloride solution into the obtained solution, washing after precipitating; (iii) subjecting high temperature pyrolysis on obtained precipitate, etching to obtain ordered mesoporous carbon, taking high temperature pyrolysis condition under nitrogen atmosphere, carbonizing for 2-4 hours at 400-500 °C, using etching agent 3-6 mole per liter (mol/L) of hydrochloric acid solution; and (iv) graphitizing the obtained ordered mesoporous carbon in argon atmosphere at 800-1600 °C for 3-6 hours to obtain the mesoporous graphene. USE - Method for coating single-layer ordered mesoporous carbon or graphene by using oxide graphene substrate used in the fields of adsorption, separation, and catalysis. ADVANTAGE - The method for coating single-layer ordered mesoporous carbon or graphene by using oxide graphene substrate is simple, has low cost, easy to amplify, has graphene surface modification, and lays the foundation.
