NOVELTY - Preparation of anode catalyst involves dispersing zirconium nitrate pentahydrate and graphite oxide in deionized water, adding sodium borohydride aqueous solution, stirring, filtering, washing, drying, dispersing obtained pre-reduced zirconium dioxide/graphene nanopowder in ethylene glycol solution, reacting, filtering, calcining obtained zirconium dioxide/graphene nanopowder, mixing chloroplatinic acid solution and tin chloride dihydrate, mixing obtained solution with ethylene glycol, reacting, adding calcined nanopowder, ultrasonically dispersing, reacting, washing, and drying. USE - Preparation of anode catalyst used for direct ethanol fuel cell. ADVANTAGE - The method enables economical preparation of anode catalyst with reduced amount of platinum, by simple process. DETAILED DESCRIPTION - Preparation of anode catalyst involves dispersing 0.08-0.27 mol/L zirconium nitrate pentahydrate and 1.03-1.74 g/L graphite oxide (GO) in deionized water, obtaining 100 ml suspension (A), adding 10 g/L sodium borohydride aqueous solution to the suspension (A), stirring for 1-2 hours, filtering, washing with 80% ethanol solution, drying, ultrasonically dispersing obtained pre-reduced zirconium dioxide/graphene nanopowder in ethylene glycol solution for 10-20 minutes, obtaining suspension (B) with solid content of 10-20 g/L, reacting at 120-160 degrees C for 3-6 hours, filtering, washing with 80% ethanol solution, drying, calcining obtained zirconium dioxide/graphene nanopowder at 550-700 degrees C for 1 hours in nitrogen atmosphere, mixing chloroplatinic acid solution and tin chloride dihydrate with platinum and tin molar ratio of 1-4:1, obtaining solution (C), mixing solution (C) with ethylene glycol in a volume ratio of 1:50-70, adjusting pH to 9-12 with ethylene glycol solution of sodium hydroxide, reacting at 120-160 degrees C for 2-4 hours, adding calcined zirconium dioxide/graphene nanopowder prepared to obtained ethylene glycol suspension (D) having solid content of 5-15 g/L, ultrasonically dispersing for 15-30 minutes, reacting at 120-160 degrees C for 3-6 hours, washing obtained sample three times with deionized water and ethanol, and vacuum-drying. The volume ratio of suspension (A) and sodium borohydride aqueous solution is 1:0.15-0.30. The concentration of sodium hydroxide in ethylene glycol solution is 1-4 mol/L. The volume ratio of suspension (D) and solution (C) is 1:2-5.
