NOVELTY - The synthesis method of graphene oxide-modified mesoporous silicon dioxide involves adding hexadecyltrimethylammonium chloride aqueous solution, triethanolamine and deionized water to ethanol and then stirring, adding tetraethyl orthosilicate to the mixture and then separating, adding graphite, sodium nitrate, concentrated sulfuric acid, potassium permanganate, water, hydrogen peroxide aqueous solution and concentrated hydrochloric acid to the mixture and then leaving, adding mesoporous silicon dioxide and graphene to the mixture and precipitating, and freeze-drying. USE - The method is useful for synthesis of graphene oxide-modified mesoporous silicon dioxide (claimed). ADVANTAGE - The method enables synthesis of graphene oxide-modified mesoporous silicon dioxide in simple manner. DETAILED DESCRIPTION - The synthesis method of graphene oxide-modified mesoporous silicon dioxide involves adding 31.2 g or 25% hexadecyltrimethylammonium chloride aqueous solution, 0.6 g triethanolamine and 192 ml deionized water to 27 ml ethanol and then stirring, adding 36.5 ml tetraethyl orthosilicate to the mixture and then separating, washing using water, concentrated hydrochloric acid and ethanol, adding 3 g graphite, 3 g sodium nitrate, 100 ml concentrated sulfuric acid, 15 g potassium permanganate, 150 ml water, 20 ml or 30% hydrogen peroxide aqueous solution and 250 ml concentrated hydrochloric acid to the mixture and then leaving, dispersing in 500 ml water, adding 300 mg mesoporous silicon dioxide, 100 ml hydrochloric acid solution and 20 g graphene to the mixture and then precipitating, and freeze-drying.
