▎ 摘　　要

NOVELTY - Preparing nano-fused cerium/graphene composite material comprises (i) mixing graphene oxide solution with ethylene glycol solution and sonicating to obtain homogeneous mixed solution, (ii) magnetically stirring the mixed solution obtained in step (i), adding cerium nitrate hexahydrate and stirring to obtain uniform suspension mixture, (iii) adding urea into the suspension mixture obtained in step (ii), adjusting pH to 11.5-12.5, mixing to obtain a mixed system, (iv) placing mixed system obtained in step (iii) in a reaction vessel for hydrothermal reaction, naturally cooling to room temperature to obtain a mixed solution, (v) centrifuging the mixed solution obtained in step (iv), collecting precipitate, washing precipitate for many times with a mixture of ethanol and deionized water, and (vi) drying the precipitate after washing in step (v) to obtain final product. USE - The method is useful for preparing nano-fused cerium/graphene composite material. ADVANTAGE - The material: has simple preparation process, low cost, high production efficiency and high conducting ability; improve the stability of the noble metal catalyst and graphene; and is suitable for industrial production. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for nano-fused cerium/graphene composite material obtained by above method.
