▎ 摘　　要

NOVELTY - Preparing titanium dioxide/graphene aerogels comprises processing titania/ graphene airgel for 30 minutes against methylene blue, the degradation rate is 95.5%, the method includes (i) adding titanium dioxide powder into an aqueous solution of graphene oxide, mechanically stirring, mixing to obtain a titanium dioxide/oxidized graphene mixed solution, (ii) adding the reducing agent into the mixed solution, and stirring the mixture to obtain the hydrothermal titania/graphene hydrogel, and (iii) drying the titania/graphene hydrogel, and removing the solvent to obtain the product. USE - The method is useful for preparing highly specific titanium dioxide/graphene aerogels (claimed). ADVANTAGE - The processing method is simple, and is environmentally-friendly.
