▎ 摘　　要

NOVELTY - Preparation of nickel oxide and cerium oxide-loaded graphene oxide comprises mixing tris(hydroxymethyl)aminomethane, concentrated hydrochloric acid, cerium salt, nickel salt, water and graphene oxide solution, reacting to 55-65 degrees C, centrifuging to remove supernatant, freezing precipitate, and calcining to 280-320 degrees C. USE - The method is for preparation of nickel oxide and cerium oxide-loaded graphene oxide used as catalyst for photonitrogen fixation reaction (claimed). ADVANTAGE - The graphene oxide can exhibit better catalytic performance at room temperature and normal pressure. The method is simple and convenient, and has no by-products. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a nickel oxide and cerium oxide-loaded graphene oxide.
