NOVELTY - Graphene/copper oxide/titanium dioxide composite material, is claimed. USE - The material is useful for photocatalytic cathodic protection (claimed). ADVANTAGE - The material has certain anti-corrosion effect under the dark environment. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing composite material comprising, depositing copper oxide nano-rod on the graphene layer by microwave hydro-thermal method using graphite oxide and copper salt as raw material and loading the titanium dioxide nanoparticles on the graphene sheets and the copper oxide nanorods with microwave hydrothermal process with titanium tetrachloride as the titanium source to obtain graphene/copper oxide/titanium dioxide composite materials.
