▎ 摘　　要

NOVELTY - A titanium dioxide-magnetite graphene composite photocatalyst, comprises titanium dioxide uniformly distributed on upper and lower surfaces of magnetite-graphene composite to form uniform nanosized titanium dioxide layer having anatase type crystal structure, is new. USE - For degradation of microcystin toxins and adsorption of other pollutants (claimed). ADVANTAGE - The present photocatalyst as compared with the traditional titanium dioxide photocatalyst, has large specific surface area, has high catalytic activity and good absorbing property; and is convenient. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the preparation of the photocatalyst.
