NOVELTY - Preparation of anode catalyst containing platinum/cerium/tin oxide for methanol fuel cell involves preparing cerium/tin composite oxide carrier, dissolving composite oxide carrier in 50 ml ethylene glycol and isopropanol mixed solution; ultrasonic treatment for 30 minutes, stirring for 30 minutes, adding 1-2 ml chloroplatinic acid solution, stirring for 2 hours with sodium hydroxide, adjusting the pH value 10 with ethylene glycol solution, reacting in microwave reactor, cooling, washing and drying to obtain the anode catalyst.    USE - For preparation of anode catalyst useful for methanol fuel cell (claimed).    ADVANTAGE - The method solves the problem that the carbon material as carrier supported platinum (Pt) nano catalyst is easy to be corroded and bad stability. The anode catalyst prepared by the method has high activity and high stability because of the strong interaction between the Pt particles and cerium base composite oxide (CexSn1-xO2) with high corrosion resistance, the catalyst noble metal active component is not easy to fall off, and has high effective utilization rate.    DETAILED DESCRIPTION - Preparation of anode catalyst Pt/CexSn1-xO2 (x not defined) for methanol fuel cell involves a) adding cerium nitrate hexahydrate (Ce(NO3)3.6H2O) and tin(IV) chloride pentahydrate (SnCl4.5H2O) (having a mol ratio of 1-9:1) to 20 ml distilled water, stirring at room temperature for 30 minutes to obtain a mixed solution (0.1-0.15 mol/l); adding sodium hydroxide (0.8-1 g), stirring for 30 minutes and adding 20 ml absolute ethyl alcohol, stirring for 30 minutes at room temperature, then putting the product into the reaction kettle, at 150-180 degrees C constant temperature and reacting for 12-24 hours, cooling to room temperature, using de-ionized water to wash till the filtrate is neutral, and then using absolute ethyl alcohol to wash 3 times, drying at 80-100 degrees C for 12 hours to obtain the composite oxide carrier CexSn1-xO2, dissolving 0.1 g CexSn1xO2 composite oxide carrier in 50 ml ethylene glycol and isopropanol mixed solution; ultrasonic treatment for 30 minutes, stirring for 30 minutes, then adding 1-2 ml chloroplatinic acid (H2PtCl6), stirring for 2 hours with sodium hydroxide (NaOH), adjusting the pH value 10 with ethylene glycol solution, placing the product in a microwave reactor at a frequency of 2450 MHz, power of 650W at 50-90 degrees C; reacting for 5-10 minutes, then cooling to room temperature, washing with deionized water until the filtrate does not containing chlorine, washing for 3 times with absolute ethyl alcohol; drying at 80-100 degrees C for 12 hours to obtain the methanol fuel cell anode catalyst Pt/CexSn1-xO2. The ethylene glycol and isopropyl alcohol mixed solution are used in a volume ratio of 4:1.
