NOVELTY - Preparation of titania-graphene oxide-carbon composite, involves adding titania, graphene oxide, and activated carbon in a mass ratio of 5:20:4 to water, stirring, adding to a hydrothermal reactor, reacting for 12 hours at 180 degrees C, filtering, and drying. USE - Preparation of titania-graphene oxide-carbon composite useful as organic dye photocatalyst (claimed). ADVANTAGE - The method enables preparation of titania-graphene oxide-carbon composite having excellent photocatalytic activity (due to presence of titanium-oxygen-carbon bond) and large specific surface area. The activated carbon functions as a microporous adsorbent to provide strong adsorption capacity with respect to soluble organic matter and other pollutants which cannot be decomposed by biochemical or oxidative degradation.
