NOVELTY - Preparation of direct methanol fuel battery anode catalyst comprises (1) heating activated carbon in air, adding activated carbon and tin dioxide (SnO2) per ethanol, mixing directly, dispersing the mixed solution to form carbon paste; (2) taking carbon paste, dropping it to graphite, carbon paper or other conductive base surface; and (3) in pre-prepared electrolyte, taking the working electrode as cathode, platinum electrode as anode and saturated calomel electrode as reference electrode to form three-electrode system, taking pulse deposition.    USE - The process is useful for preparing direct methanol fuel battery anode catalyst (claimed). The direct methanol fuel battery anode catalyst is useful in other fuel battery cathode and anode catalysts and other fields as air reforming, organic matter degradation and pollutant treatment.    ADVANTAGE - Preparation of direct methanol fuel battery anode catalyst can directly deacidize catalyst at low temperature, which substantially increases methanol electric oxidation to improve catalyst utilization ration with simple preparation.    DETAILED DESCRIPTION - Preparation of direct methanol fuel battery anode catalyst comprises (1) heating activated carbon in air of 400-700 degrees C for 20-70 minutes, adding 3-9 mg activated carbon and 1.5-4.5 mg SnO2 per ethanol, mixing directly, placing in the ethanol, preparing mixed solution by activated carbon, ethanol suspension solution having SnO2 and ion emulsion of 5% mass percentage according to volume ratio of 100:2-100:8, dispersing the mixed solution with ultrasonic wave for 40-120 minutes to form carbon paste; (2) taking 150-350 mu l carbon paste/cm2, dropping it to graphite, carbon paper or other conductive base surface to prepare working electrode used in electrolytic deposition process after the ethanol is completely evaporated; and (3) in pre-prepared electrolyte, taking the working electrode as cathode, platinum electrode as anode and saturated calomel electrode as reference electrode to form three-electrode system, taking pulse deposition at 20-40 degrees C, the current density 1-10.0 mA/cm2 and its on/off time ratio 1:0.5-10.
