The prepared titanium dioxide intercalated graphene oxide has good stability and high catalytic efficiency, and is reusable. DETAILED DESCRIPTION - Preparing titanium dioxide intercalated graphene oxide, comprises (i) placing a expanded graphite and concentrated sulfuric acid (98%) in a glass container, completely stirring under ice water bath, slowly adding potassium permanganate until complete reaction of potassium permanganate, adding de-ionized water under different temperature under mechanical stirring, uniformly mixing, adding hydrogen peroxide, where the solution changes from black brown to bright yellow, washing resulting solution to neutral using hydrochloric acid and de-ionized water under centrifugal dispersing condition to obtain graphene oxide, (ii) taking the prepared graphene oxide in a hydrothermal reactor and ultrasonicating under certain temperature conditions to obtain a graphene oxide containing interlayer water, (iii) drying and weighing the graphene oxide containing interlayer water, adding carbon tetrachloride, where carbon tetrachloride converts into butyl titanate by hydrolysis, performing ultrasonic dispersion to react completely under sealing condition, adding a small amount of anhydrous alcohol, and reacting at a certain temperature in a hydrothermal reactor to obtain titanium dioxide intercalated graphene oxide.
