NOVELTY - Graphite oxide is ultrasonically dispersed in deionized water. Cerium nitrate hexahydrate crystals are added to dispersion liquid, stirred, aqueous ammonia is further added, heated, reacted at 220-240 degrees C for 12-24 hours, and filtered, to obtain slurry. The obtained slurry is dried to obtain graphene loaded ceria nano cubic complex. The amount of graphite oxide and cerium nitrate hexahydrate is added in mass ratio of 1: 18.5-43.5. The amount of ammonia added per mg of graphite oxide is 0.05-0.15 mL. The amount of deionized water added per mg of graphite oxide is 2-4 mL. USE - Preparation of graphene loaded ceria nano cubic complex. ADVANTAGE - The method efficiently produces graphene loaded ceria nano cubic complex without environmental pollution by simple process. The graphene loaded ceria nano cubic complex has excellent luminous performance, and high productivity.
