NOVELTY - Removal of carbon monoxide of graphene oxide supported gold platinum catalyst comprises taking graphite powder, pouring into sulfuric acid, stirring in oil bath, adding potassium sulfate and phosphorus pentoxide, stirring, vacuum suction-filtering, slowly adding concentrated sulfuric acid and potassium permanganate to filtrate, stirring at 35 degrees C for 2 hours, removing upper layer, adding chloroauric acid solution and chloroplatinic acid solution, stirring under vibration, centrifuging, adding urea, ferric hydroxide and nickel hydroxide, stirring, reacting, adding dispersant and drying. USE - Method for removing carbon monoxide of graphene oxide supported gold platinum catalyst (claimed). ADVANTAGE - The method has simple operation, no secondary environmental pollution, and has carbon monoxide removal rate of more than 99.7%. DETAILED DESCRIPTION - Removal of carbon monoxide of graphene oxide supported gold platinum catalyst comprises taking 3-5 g graphite powder, pouring into 12-15 mL sulfuric acid, stirring in oil bath at 75-80 degrees C, adding 2.5-3.0 g potassium sulfate and 2.5-3.0 g phosphorus pentoxide, stirring for 4.5-6.5 hours, vacuum suction-filtering by 0.2 mm microporous film, slowly adding 120-125 mL concentrated sulfuric acid and 15-18 g potassium permanganate to filtrate, stirring at 35 degrees C for 2 hours, removing upper layer, adding 20-30 mL of 0.5 mol/L chloroauric acid solution and 25-40 mL of 0.6 mol/L chloroplatinic acid solution, stirring under vibration, centrifuging, adding 5-15 g urea, 3-8 g ferric hydroxide and 5-10 g nickel hydroxide, stirring, reacting for 10-30 minutes, adding 3-5 g dispersant and drying at 105-110 degrees C for 1.5 hours. The dispersant is zinc stearate, magnesium stearate or barium stearate.
