NOVELTY - An anode catalyst is prepared by obtaining suspension containing carbon black powder, adding tin tetrachloride pentahydrate and antimony trichloride into the suspension, and heating to obtain mixing solution; adding alkali into the mixing solution, grinding the mixing solution into powder, and roasting the powder to obtain antimony tin oxide (ATO)/carbon (C) powder; dissolving hexachloroplatinic (IV) acid into ethylene glycol and heating the solution in inert atmosphere to obtain platinum sol-gel; and dispersing the ATO/C into absolute ethyl alcohol to obtain ATO/C suspension.    USE - Method for preparing anode catalyst for direct methanol fuel cell (claimed).    ADVANTAGE - The method has easy process and low cost. The obtained platinum-ATO/C catalyst has high dispersibility, uniformly particle size, no obvious reuniting phenomenon, lower onset potential, and high current density, showing good electro-catalysis, antioxidative activity and efficiency.    DETAILED DESCRIPTION - Preparing anode catalyst of a direct methanol fuel cell comprises:    (A) grinding carbon black into powder, dissolving into absolute ethyl alcohol, mixing the powder and solution to obtain suspension, adding tin tetrachloride pentahydrate and antimony trichloride into the suspension, heating the obtained solution to 30-70 degrees C, and stirring for 30-60 minutes until the powder is fully dissolved and mixed as mixing solution, a molar ratio of antimony and tin being 1:10-1:50, and a total mass ratio of tin tetrachloride pentahydrate and antimony trichloride and carbon black mass being 1:10-1:50;    (B) adding alkali into the mixing solution to adjust pH to 1-10, reacting for 1-5 hours, filtering, washing, drying, grinding the mixing solution into powder, and roasting the powder for 2-4 hours at 500-800 degrees C to obtain ATO/C powder;    (C) dissolving hexachloroplatinic (IV) acid into ethylene glycol and heating the solution in inert atmosphere at 120-160 degrees C for 0.5-2 hours to obtain platinum sol-gel; and    (D) dispersing the ATO/C into absolute ethyl alcohol to obtain ATO/C suspension, mixing the platinum sol-gel with the ATO/C suspension, adding acid to adjust the pH value to 4-7, washing the mixing solution until no chlorine ion is contained in the mixing solution, and drying the mixing solution to obtain platinum-ATO/C catalyst which carries active metal platinum, a mass ratio of simple substance platinum in platinum-ATO/C catalyst being 10-30%.
