NOVELTY - Nitrogen-doped graphene loading palladium/nickel catalyst comprises 1 pts. wt. nickel sulfate hexahydrate, 4-6 pts. wt. nitrogen-doped graphene and 20-25 pts. wt. potassium borohydride and 0.05 mol/l palladium(II) chloride solution, where molar ratio between nickel and palladium is 1:2-4. USE - Used as nitrogen-doped graphene loading palladium/nickel catalyst. ADVANTAGE - Nitrogen-doped graphene loading palladium/nickel catalyst has larger desorption peak area and excellent catalytic activity, higher oxidation-reduction catalytic properties, stability and greater catalyst electrochemically active surface area. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing nitrogen-doped graphene loading palladium/nickel catalyst comprising (i) adding nitrogen-doped graphene into distilled water and sonicating to disperse uniformly to obtain nitrogen-doped graphene solution, (ii) adding potassium borohydride to the distilled water to dissolving to obtain potassium borohydride solution, (iii) adding palladium(II) chloride solution and nickel sulfate hexahydrate to the solution of nitrogen-doped graphene and sonicating, (iv) adding solution of potassium borohydride prepared in step (ii) to step (iii) resulting solution, and then reacting at 40-55 degrees C under nitrogen protection for 5-7 hours, and (v) subjecting the product after the reaction of step (iv) to filtration, filtering, washing and drying to obtain final product.
