▎ 摘  要

NOVELTY - Preparing graphene loaded cerium oxide nanoparticle composite material comprises (i) adding 0.50-0.70 g graphene oxide into 40-70 ml deionized water to obtain graphene oxide dispersion, (ii) taking 0.5-1 g cerium nitrate hexahydrate and dissolving in 20-40 ml deionized water to obtain cerium nitrate hexahydrate solution, and adding the cerium nitrate hexahydrate solution to the graphene oxide dispersion obtained in the step (i) to obtain a solution A, (iii) taking 1-1.2 ml aqueous ammonia and 1-1.2 ml hydrazine hydrate into solution A to obtain solution B, and(iv) hydrothermally reacting solution B in the reaction kettle, where the temperature of the hydrothermal reaction is 180-250 degrees C, after the reaction is over, washing and drying the product to obtain graphene loaded cerium oxide nanoparticle composite material. USE - The method is useful for preparing graphene loaded cerium oxide nanoparticle composite material. ADVANTAGE - The method utilizes cerium oxide grows uniformly and densely on surface of graphene oxide, which improves surface roughness of composite material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for graphene-loaded cerium oxide nanoparticle composite material prepared by above mentioned method.
