NOVELTY - A nanocomposite graphene titanium dioxide comprises dominant nanospheres with diameter 200 nm and 4.50-10 wt.% graphene. USE - Nanocomposite graphene titanium dioxide. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing nanocomposite of graphene titanium dioxide, which involves mixing tetrabutyl titanate with solution of graphene oxide in a ratio 1:4-1:8, subjecting the mixture to ultrasonic waves, carrying out centrifugation at 9000 rpm for 1 hour, washing with ethanol, and calcinating in vaccum at 400 degrees C at pressure of 10-7 bar to obtain nanocomposite graphene titanium dioxide.
