▎ 摘　　要

NOVELTY - Preparing graphene/titanium dioxide composite material comprises adding titanium dioxide sample into an arc discharge device provided with graphite as a cathode and an anode, then vacuumizing, introducing mixed gas of helium gas and hydrogen gas, opening the electric arc discharge device, and regulating the current size and reaction time. USE - The method is useful for preparing graphene/titanium dioxide composite material (claimed). ADVANTAGE - The method is capable of simply, conveniently and rapidly preparing the graphene/titanium dioxide composite material with strong practicability.
