▎ 摘　　要

NOVELTY - Preparing low light response titanium dioxide reducing graphene composite comprises e.g. (i) taking graphene oxide, ethanol and deionized water, placing in water bath and stirring, (ii) dissolving tetrabutyl titanate in absolute ethanol, adding into adsorption system and reacting to obtain suspension system containing titanium oxide- graphene oxide particles, (iii) introducing resulting suspension into autoclave, sealing and treating, and (iv) treating resulting reaction solution, cooling, separating, washing and drying. USE - The composite is useful in treating artificial seawater organic matter (claimed). ADVANTAGE - The method: is simple and highly efficient. DETAILED DESCRIPTION - Preparing low light response titanium dioxide reducing graphene composite comprises (i) taking graphene oxide, ethanol and deionized water, placing in water bath and stirring until adsorption system equilibrium is obtained, (ii) dissolving tetrabutyl titanate in absolute ethanol, adding into adsorption system in dropwise manner and reacting to obtain suspension system containing titanium oxide- graphene oxide particles, (iii) introducing resulting suspension into autoclave, sealing and treating thermally at 160-180 degrees C, and (iv) treating resulting reaction solution, cooling, separating, washing and drying. An INDEPENDENT CLAIM is also included for low light response titanium dioxide reducing graphene composite prepared by the above mentioned method.
