NOVELTY - Preparing noble metal carbon-based fuel cell oxygen reduction catalyst comprises e.g. adding graphene, carbon nanotubes, and carbon black, adding to distilled water beaker, and adding potassium chloropalladate into a beaker, homogenizing after ultrasonic mixing, stirring using magnetic stirrer, centrifuging and drying to give product A, taking the same amount of aniline as sample A, and same amount of ammonium persulfate as aniline, adding sample A to the previously taken aniline and adding hydrochloric acid solution to adjust the pH value and stirring to obtain the solution. USE - The method is useful for preparing noble metal carbon-based fuel cell oxygen reduction catalyst. ADVANTAGE - The method is simple and suitable for mass production. DETAILED DESCRIPTION - Preparing noble metal carbon-based fuel cell oxygen reduction catalyst comprises (1) adding 20-200 mg graphene, carbon nanotubes, and carbon black, adding to a 30-300 ml distilled water beaker, and adding 19-190 mg potassium chloropalladate into a beaker, homogenizing after ultrasonic mixing, stirring using magnetic stirrer for 1 hour, centrifuging and drying to give product A, (2) taking the same amount of aniline as sample A, and same amount of ammonium persulfate as aniline, adding sample A to the previously taken aniline and adding 0.2M hydrochloric acid solution to adjust the pH value to 2 and stirring for 1 hour to obtain the solution, taking the ammonium persulfate, adding to the mixed solution, and stirring for 24 hours, centrifuging and drying to obtain sample B, (3) adding sample B into a tube furnace at 700-990 degrees C for 2 hours, using nitrogen as a protective atmosphere, after the end of the heat, cooling furnace to room temperature to obtain sample C, (4) adding sample C, soaking in a 1M hydrochloric acid solution for half an hour, and washing using clean water to obtain sample D by repeating 2 times, (5) placing sample D in an oven at 80 degrees C, drying to obtain the product.
