▎ 摘  要

NOVELTY - Preparation of lanthanide oxide/graphene oxide nano composite, involves adding 100 mg graphene oxide to 100 mL dimethylformamide in a container, ultrasonically dispersing for 1 hour to obtain a suspension, adding 100 mg lanthanide chloride to the suspension, heat-refluxing for 1 hour, cooling to room temperature to obtain a black precipitate, centrifugally separating the solid, and washing with ethanol and water thrice. USE - Preparation of lanthanide oxide/graphene oxide nano composite (claimed). ADVANTAGE - The method enables simple and quick preparation of lanthanide oxide/graphene oxide nano composite, using a simple device under easy-to-control conditions, without requiring addition of additional stabilizer and additive. The nano composite comprises lanthanide oxide nanoparticles having a size of 8-15 nm, distributed uniformly on the surface of graphene oxide.
