NOVELTY - 0.01-0.015 g Cerium oxide hollow sphere and 0.035-0.04 g Vulcan XC-72 (RTM: carbon black) are dissolved in a mixed solution of 30 mL isopropyl alcohol and ethylene glycol, ultrasonically treated, and stirred. 0.1 Mol/L chloroplatinic acid solution is added and stirred. 1 Mol/L ethylene glycol solution of sodium hydroxide is added and reaction solution is added in a microwave reactor for 60-70 seconds, cooled to room temperature, washed with deionized water and anhydrous ethanol, and dried at 80-100 degrees C for 3-6 hours to obtain platinum/cerium oxide-carbon hollow ball.    USE - Manufacture of platinum/cerium oxide-carbon hollow ball for anode catalyst of direct methanol fuel cell.    ADVANTAGE - The platinum/cerium oxide-carbon hollow ball is easily manufactured with favorable catalytic ability and stability.    DETAILED DESCRIPTION - 0.1-0.5 g Cerium nitrate hexahydrate is dissolved in 10 mL distilled water and stirred at room temperature for 30 minutes. 30 mL Polyethylene glycol-400 is then added and stirred at room temperature for 30 minutes. The solution is added into a reactor, reacted at 150-220 degrees C for 12-48 hours, cooled to room temperature, washed with deionized water and anhydrous ethanol, and dried at 80-100 degrees C for 5-12 hours. Milky white precipitate is obtained, the white precipitate is added in a tubular furnace, calcined at 300-500 degrees C for 1-5 hours, and cooled to room temperature, to obtain cerium oxide hollow sphere. 0.01-0.015 g Cerium oxide hollow sphere and 0.035-0.04 g Vulcan XC-72 (RTM: carbon black) are dissolved in a mixed solution of 30 mL isopropyl alcohol and ethylene glycol, in volume ratio of 4:1, ultrasonically treated for 1 hours, and stirred for 3 hours. 0.1 Mol/L chloroplatinic acid solution is added and stirred for 3 hours. 1 Mol/L ethylene glycol solution of sodium hydroxide is added and pH is adjusted to 12. The reaction solution is added in a microwave reactor for 60-70 seconds, cooled to room temperature, washed with deionized water and anhydrous ethanol, and dried at 80-100 degrees C for 3-6 hours to obtain platinum/cerium oxide-carbon hollow ball.
