NOVELTY - The method comprises preparing graphite oxide and graphene oxide using normal chemical method, taking graphite oxide dispersed into de-ionized water and then ultrasonic dispersing to obtain dispersed precursor solution, where the precursor solution of the graphene oxide is 0.1-0.3mg/ml, and adding ammonium hexafluorotitanate into the solution, uniformly stirring the mixed solution (0.01-0.05mol/L), and placing the solution into a high pressure kettle with polyfluortetraethylene and titanium dioxide/graphene composite nanomaterial at 150-170 degrees C for 4-24 hours. USE - The method is useful for preparing titanium dioxide/graphene composite nanomaterial. ADVANTAGE - The method is capable of simply preparing the titanium dioxide/graphene composite nanomaterial with high yield. DETAILED DESCRIPTION - The method comprises preparing graphite oxide and graphene oxide using normal chemical method, taking graphite oxide dispersed into de-ionized water and then ultrasonic dispersing to obtain dispersed precursor solution, where the precursor solution of the graphene oxide is 0.1-0.3mg/ml, and adding ammonium hexafluorotitanate into the solution, uniformly stirring the mixed solution (0.01-0.05mol/L), placing the solution into a high pressure kettle with polyfluortetraethylene and titanium dioxide/graphene composite nanomaterial at 150-170 degrees C for 4-24 hours, naturally cooling the mixed solution at a room temperature, washing the mixed solution with the de-ionized water, and filtering and vacuum drying the solution to obtain titanium dioxide/graphene composite nanomaterial with crystal surface. An INDEPENDENT CLAIM is included for a titanium dioxide or graphene composite nanomaterial.
