▎ 摘　　要

NOVELTY - Producing anatase titania-reduced graphene oxide composite, comprises (a) dissolving anatase titania precursor in a solvent to prepare a precursor solution, (b) dispersing graphene oxide in the precursor solution to prepare a colloidal solution, (c) spraying the colloidal solution with a droplet, and (d) applying heat to the droplet. USE - The method is useful for producing anatase titania-reduced graphene oxide composite as photocatalyst, sodium secondary battery, lithium secondary battery (all claimed), air purifier, water purifier, antibacterial agent and solar battery, and in composition for spray pyrolysis process. ADVANTAGE - The method is simple, economical, mass-productivity and environmentally friendly. The anatase titania-reduced graphene oxide composite has high specific surface area and light transmittance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for anatase titania-reduced graphene oxide composite having a structure in which anatase titania is dispersed on reduced graphene oxide.
