▎ 摘　　要

NOVELTY - A titanium dioxide-graphene-silver hybrid nanocomposite preparing method involves introducing sol gel to a microwave irradiation at 50% microwave power for 18 minutes to prepare an irradiated sample of titanium dioxide-graphene oxide sample, where the sol gel comprises titanium dioxide containing gel along with graphene containing sol, adding 0.5 M silver nitrate solution to the titanium dioxide-graphene oxide sample for preparing a titanium dioxide-graphene-silver hybrid suspension, irradiating the titanium dioxide-graphene-silver hybrid suspension with microwave irradiation for 12 minutes to prepare irradiated titanium dioxide-graphene-silver hybrid suspension, drying irradiated titanium dioxide-graphene-silver hybrid suspension at a temperature of 80 degrees C to prepare dried titanium dioxide-graphene-silver hybrid composite, and calcining the dried titanium dioxide-graphene-silver hybrid composite at a calcination temperature of 300 degrees C for five hours to obtain the finished product. USE - Method for preparing titanium dioxide-graphene-silver hybrid nanocomposite. ADVANTAGE - The method enables preparing titanium dioxide-graphene-silver hybrid nanocomposite with enhanced energy density, specific capacitance, power density and life time. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a titanium dioxide-graphene-silver hybrid nanocomposite, comprising 70-98 wt.% titanium oxide, 0.1-20 wt.% graphene oxide and 2-10 wt.% silver, where the silver is formed on the titanium oxide, and average particle size of the titanium dioxide-graphene-silver hybrid nanocomposite is ranging from 12-15 nanometers.
