▎ 摘  要

NOVELTY - A palladium-transition metal oxide-graphene ternary composite catalyst comprises palladium salt and transition metal oxide-graphene oxide binary composite at a mass ratio of 1:40-40:1. Mass ratio of the transition metal oxide and the graphene oxide in the binary composite is 1:10-10:1. USE - Palladium-transition metal oxide-graphene ternary composite catalyst for use in organic reaction and fuel cell. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the composite catalyst comprising: (A) ultrasonically dispersing the graphite oxide in water; (B) adding transition metal salt solution to the dispersing system, stirring and reacting; (C) centrifuging the reactant, separating out the solid product, washing with de-ionized water, spray drying continuously to obtain the transition metal oxide-oxidized graphite alkene compound; (D) adding water and ethylene glycol in the mixed solution of ultrasonic dispersion; (E) adding nitric acid solution, uniformly mixing, placing in water heat stillage; and (F) centrifuging the reactant, separating out the solid product, washing with de-ionized water, and spray drying continuously to obtain the palladium-transition metal oxide-graphene three-element composite catalyst.
