NOVELTY - A nitrogen-containing graphene-supported platinum-palladium-nickel three-component nano-alloy catalyst comprises platinum in catalyst, palladium, nickel and rest of nitrogen-doped graphene, where the catalyst is prepared by placing graphene oxide and urea in hydrothermal reaction kettle, taking out the mixture from hydrothermal reaction kettle and heating by microwave under nitrogen atmosphere, reducing platinum-palladium-nickel precursor through a batch microwave process using reducing agent, depositing on a high specific surface nitrogen-doped graphene and subjecting heat treatment process. USE - Nitrogen-containing graphene-supported platinum-palladium-nickel three-component nano-alloy catalyst for use in electro-catalysis field of direct methanol fuel cell. ADVANTAGE - The nitrogen-containing graphene-supported platinum-palladium-nickel three-component nano-alloy catalyst has high specific surface, and better conductivity and corrosion resistance. DETAILED DESCRIPTION - A nitrogen-containing graphene-supported platinum-palladium-nickel three-component nano-alloy catalyst comprises 10-50 mass% platinum in catalyst, 5-30 mass% palladium, nickel 1-20 mass%, and rest of nitrogen-doped graphene with high specific surface, where the catalyst is prepared by placing graphene oxide and urea having a mass ratio of 1:0.2-2 in hydrothermal reaction kettle, incubating at 120-200 for 0.5-3 hours, taking out the mixture of graphene and urea from the hydrothermal reaction kettle and heating by microwave under nitrogen atmosphere at 500-1100 degrees C to obtain nitrogen doped graphene with high specific surface, reducing platinum-palladium-nickel precursor through a batch microwave process by using polyol as a reducing agent, depositing on a high specific surface nitrogen-doped graphene and subjecting heat treatment process to obtain catalyst.
