NOVELTY - Preparing graphene titanium dioxide composite involves taking the container, adding mixed solution of titanate and methanol, then graphene, acutely stirring uniformly for 10 min, adding N, N-dimethyl amide, ultrasonically stirring for 15 minutes, fully mixing the titanate with the graphene, condensing and refluxing the mixed solution of the graphene and the titanate, stirring at constant temperature, adding a certain amount of sodium hydroxide while stirring. After the sodium hydroxide is added, keeping stirring at a constant temperature for 5 hours, and after the completion of the reaction, cooling to room temperature to obtain a solution containing a precipitate, filtering the solution containing the precipitate, and then washing and drying the filtered solid to obtain the graphene titanium dioxide. USE - Method for preparing graphene titanium dioxide composite. ADVANTAGE - The method uses titanate and sodium hydroxide solution to react and then through the hydrothermal method, successfully loads titanium dioxide on graphene, which has higher photocatalytic efficiency than single titanium dioxide
