NOVELTY - A composite catalyst comprises a palladium nanoparticle as catalytic active component, titanium dioxide and carbon nanotube as composite carrier material. The metal palladium nanoparticle and titanium dioxide are uniformly distributed on the surface of the carbon nanotube. The palladium is present at 10-20 mass%. The titanium dioxide is present at 10-50 mass%.    USE - Composite catalyst useful as alcohol alkaline fuel cell catalyst.    ADVANTAGE - The catalyst has high and stable electrochemical oxidation activity.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of composite catalyst comprising:    (A) placing carbon in concentrated sulfuric acid and concentrated nitric acid mixture at 70-90 degrees C constant ultrasonic for 6-8 hours, washing with deionized water and filtering until the filtrate is neutral pH, low temperature drying to obtain functional groups of the carbon nanotube material, and ultrasonically dispersing in deionized water to obtain a carbon nanotube solution;    (B) placing the titanium oxide powder in a muffle furnace at 700-800 degrees C, calcining for 4-6 hours, and after cooling, placing 10 M sodium hydroxide (NaOH) at 110-120 degrees C for 22-24 hours, activating reaction with deionized water after the reaction, washing and filtering, adjusting pH of the filtrate to have a neutral pH, and drying to give the activated titanium dioxide nanoparticles;    (C) dispersing palladium chloride in deionized water and ultrasonic for 20-30 minutes to obtain a homogeneous aqueous solution of palladium chloride;    (D) blending aqueous solution of palladium chloride solution to the carbon nanotube, where the palladium carbon is 10-20 mass%, further stirring for 1-2 hours, adding the excess of reducing agent dropwise and stirring for 3-4 hours, and filtering the complete reaction, and washing with deionized water until the filtrate was neutral; and    (E) adding activating titanium dioxide powder in 10-50 mass% titania nanotubes, stirring for 4-6 hours, filtering the solution and washing 3-4 times, and drying to obtain the composite catalyst material.
