TiO2- MANUFACTURING METHOD OF TiO2 FLOWER SPHERE-REDUCED GRAPHENE OXIDE COMPOSITES

摘要

The present invention relates to a flower-like spherical TiO 2₂(1) preparing graphene oxide which has been peeled off by an oxidation reaction of graphite; and (2) a step of preparing a graphene oxide composite material. (2) Thermal decomposition of TBT (tetrabutyl titanate) and acetic acid by solvent,₂/RTI (3) The graphene oxide prepared in the step (1) and the flower-like spherical TiO 2 prepared in the step (2)₂; And (4) drying the hydrothermally synthesized sample in the step (3).According to the present invention as described above, the flower-like spherical TiO₂A high pore structure and a new energy level of reduced graphene oxide, it is possible to produce a composite having greatly improved optical activity.
