NOVELTY - A palladium-molybdenum/titania nanowire catalyst comprises nano-titania nanowires with palladium-molybdenum alloy composition, and has content of nano-titania nanowires of 95.9 %mass and palladium-molybdenum alloy content of 5-1 %mass. The molar ratio of palladium and molybdenum in palladium-molybdenum alloy is 3:7, 1:1 or 7:3.    USE - Palladium-molybdenum/titania nanowire catalyst is used for anode of direct methanol fuel cell.    ADVANTAGE - The palladium-molybdenum/titania nanowire catalyst has improved catalytic oxidation property and anti-carbon monoxide poison capacity, and is economical. The usage amount of catalyst is reduced.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of palladium-molybdenum/titania nanowire catalyst, which involves adding butyl titanate to absolute ethyl alcohol, stirring and adding mixture of absolute ethyl alcohol, glacial acetic acid and deionized water, hydrolyzing to form sol and continuously stirring, drying and grinding to obtain titania nanopowder, adding titania nanopowder into high-pressure reactor, adding 10 mol/L sodium hydroxide solution, stirring, heating, reacting and separating, drying at 60 degrees C, washing with diluted hydrochloric acid and deionized water and drying at 400-600 degrees C in air for 3 hours to obtain titania nanowire, adding titania nanowire to ethylene glycol, ultrasonically dispersing to obtain titania nanowire dispersion liquid, adding palladium chloride to ethylene glycol, to form palladium chloride/ethylene glycol solution, adding molybdenum chloride to ethylene glycol solution to form molybdenum chloride/ethylene glycol solution, dripping palladium chloride/ethylene glycol solution and molybdenum chloride/ethylene glycol solution to titania nanowire dispersion liquid and ultrasonically dispersing, adding sodium hydroxide to dissolve in ethylene glycol to form sodium hydroxide/ethylene glycol solution, dripping sodium hydroxide/ethylene glycol solution and ultrasonically dispersing, reacting dispersion liquid at 160 degrees C for 5 hours, washing with deionized water and drying.
