NOVELTY - Butyl titanate is dissolved in anhydrous ethanol, glacial acetic acid and deionized water are added, and obtained sol is dried, to obtain titanium dioxide nanopowder. Titanium dioxide nanopowder and sodium hydroxide solution are added, and obtained titanium dioxide nanotube is dispersed in ethylene glycol, to obtain titanium dioxide nanotube-dispersion. Palladium/silver catalyst is added to palladium chloride solution to obtain dispersion liquid. Silver nitrate solution is dropped to dispersion liquid and resulting mixture is vacuum-dried to obtain palladium-silver-titanate catalyst.    USE - Preparation of palladium-silver-titanate catalyst used for anode of direct methanol fuel cell.    ADVANTAGE - The method economically provides palladium-silver-titanate catalyst having excellent carbon monoxide poisoning resistance, and improves catalytic oxidation performance on methanol.    DETAILED DESCRIPTION - Butyl titanate is dissolved in anhydrous ethanol, stirred, mixture of glacial acetic acid and deionized water is added and hydrolyzed to form sol. The sol is stirred continuously, allowed to stand for 2-3 days, gel is formed, dried in vacuum at 80 degrees C for 8-10 hours. The resulting mixture is ground in muffle furnace at 400-600 degrees C for 3 hours, to obtain titanium dioxide nanopowder. Titanium dioxide nanopowder is added into reflux cooling device, sodium hydroxide solution having concentration of 100 mol/L is added, stirred, heated to 120-150 degrees C, refluxed for 24 hours, centrifuged and washed with acetic acid and deionized water for 6-8 times. The resulting powder is calcined in air at 400-600 degrees C for 3 hours, to obtain titanium dioxide nanotube. Titanium dioxide nanotube is added to 10-20 ml ethylene glycol, and dispersed uniformly to obtain titanium dioxide nanotube dispersion. Palladium chloride is dissolved in ethylene glycol to form palladium chloride ethylene glycol solution. Palladium/silver catalyst is added to palladium chloride ethylene glycol solution and dispersed in titanium dioxide nanodispersion liquid to obtain dispersion liquid. Sodium hydroxide is dissolved in ethylene glycol, the resulting mixture is dropped to obtained dispersion liquid, pH is adjusted to 8.5-12, to obtain suspension. Potassium borohydride is dissolved in ethylene glycol to obtain potassium borohydride solution having concentration of 0.2-0.5 mol/l. The resulting mixture is dropped to ethyl alcohol, reacted for 2-6 hours, washed with deionized water till the filtrate is free from chloride ion and sulfate ion, and dried in vacuum at 80-120 degrees C to obtain palladium-titanium dioxide. The palladium-titanium dioxide is dispersed in ethylene glycol to obtain palladium-titanium dioxide dispersion liquid. Silver nitrate is dissolved in ethylene glycol to obtain silver nitrate solution. The silver nitrate solution is dropped to palladium-titanium dioxide dispersion liquid, stirred, protected under inert gas atmosphere, and reacted for 2-6 hours. The resulting mixture is washed with deionized water, and vacuum-dried at 80-120 degrees C, to obtain palladium-silver-titanate catalyst. The molar ratio of butyl titanate, anhydrous ethanol, glacial acetate and deionized water is 1:20-10:1-2.5:2-6. The molar ratio of palladium and silver in palladium/silver catalyst is 1:1. The content of palladium-silver catalyst is 1.5-5 wt.%.
