DETAILED DESCRIPTION - Preparing catalyst involves adding 25ml of concentrated sulfuric acid into flask, cooling to 0-2 degrees C, adding 0.5g natural flake graphite, 0.5g sodium nitrate, and 3g potassium permanganate particles, and stirring, placing the flask in a constant temperature water bath at 35 divide by 2 degrees C, and continue stirring when the temperature of the reaction solution rises to 35 divide by 2 degrees C, adding 46ml deionized water to the solution, stirring for 15 minutes at 98 divide by 2 degrees C, adding 140ml deionized water and 3ml 30 wt.% hydrogen peroxide to react for 40 minutes after high temperature reaction, washing with 1-3 wt.% hydrochloric acid solution, and then washing with deionized water to neutrality multiple times to obtain 5-15 wt.% graphene oxide suspension, adding certain amount of citric acid, concentrated nitric acid, and tetrabutyl zirconate to the above graphene oxide solution, and magnetically stirring to obtain a sol. The molar ratio of the citric acid, nitric acid, and tetrabutyl zirconate is (2-3):(0.2-0.3):1, introducing the above-mentioned sol into a test tube, sealing, and placing in a vacuum drying oven at 80-90 degrees C, and reacting for 24-36 hours to obtain a shaped gel. The gel is introduced in multiple test tubes into a hydrothermal reaction kettle containing an aqueous solution of chloroplatinic acid and nickel nitrate, the nitrogen is used to remove the air, and performed a hydrothermal reaction to obtain a catalyst precursor, filtered and washed the catalyst precursor, freeze-dried, and performed reduction treatment in a reducing atmosphere to obtain product.
