▎ 摘　　要

NOVELTY - A graphene-based magnetic photocatalytic nano-composite material comprises titanium dioxide nanoparticles and iron(III) oxide nanoparticles loaded directly on graphene sheets. The mass ratio of titanium dioxide nanoparticles and iron(III) oxide nanoparticles is 1:1-4. USE - Graphene-based magnetic photocatalytic nano-composite material (claimed). ADVANTAGE - The graphene-based magnetic photocatalytic nano-composite material is environmentally-friendly, and economically and efficiently prepared by a simple process. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene-based magnetic photocatalytic nano-composite material, which involves adding graphite oxide and surfactant in water and ethanol, ultrasonically dispersing, adding surfactant, mixing uniformly, adding superparamagnetic iron(III) oxide nanoparticles and anatase titanium dioxide nanoparticles, mixing, adding the resultant solution into a hydrothermal reactor, performing hydrothermal reaction, obtaining reaction mixture, separating by applying magnetic field, washing using deionized water and drying under vacuum.
