NOVELTY - Preparation of graphene oxide loaded gold-palladium or gold-silver double-metal nanoparticles involves mixing 10 pts. wt. graphene oxide, 1 pt. wt. sodium hydroxide, palladium chloride and bimetallic nanoparticles, stirring at 40-90 degrees C for 0.5-12 hours and obtaining black precipitate bimetallic nanoparticles, centrifuge mixture, washing product using deionized water and ethanol repeatedly, and vacuum-drying at 60 degrees C for 12 hours. The weight ratio of bimetallic nanoparticles to palladium chloride is 0.1-3.8. USE - Preparation of graphene oxide loaded gold-palladium or gold-silver double-metal nanoparticles used for manufacture of methanol fuel cell, ethanol fuel cell and formic acid fuel cell. ADVANTAGE - The method efficiently and economically provides graphene oxide loaded gold-palladium or gold-silver double-metal nanoparticles.
