▎ 摘　　要

NOVELTY - Preparing graphene load cerium oxide catalyst comprises dropping the cerium trichloride solution till the alcohol solution of concentrated ammonia water, stirring at 40-60 degrees C, insulating for 1-1.5 hour to obtain cerium oxide suspension, adding the graphene oxide into the distilled water to obtain oxidized graphene suspension, (ii) taking the cerium oxide suspension and the oxidized grapheme suspension, mixing and heating to 160-180 degrees C, performing hydrothermal reacting for 6-10 hours and removing the supernatant to obtain solid precipitate and drying. USE - The method is useful for preparing graphene load cerium oxide catalyst (claimed). ADVANTAGE - The method has high catalytic activity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for active catalytic component cerium oxide and the graphene carrier prepared by above method.
