NOVELTY - Functionalized carbon carrier, carbon powder, hydrogen peroxide and sulfuric acid are added to flask, to obtain functionalized carbon powder. Functionalized carbon powder, iridium precursor, nickel precursor and sodium citrate and deionized water are dispersed in deionized water, to obtain carbon powder suspension. Aqueous ammonia is added, and ground to obtain carbon-supported nickel complex. Hydrogen and argon are mixed with nickel complex, and heated. The mixture is cooled and dried, to obtain carbon-nickel alloy-containing iridium catalyst.    USE - Preparation of molybdenum catalyst used for anode of non-hydrogen proton exchange membrane fuel cell.    ADVANTAGE - The method enables the preparation of molybdenum catalyst having uniform dispersion of particles, with improved hydrogen and oxidization activity, and metal utilization ratio, by simple process.    DETAILED DESCRIPTION - Functionalized carbon carrier and 1 g Vulcan XC-72 (RTM: modified carbon powder) are added into 500 ml round bottom flask. 150 ml Hydrogen peroxide with concentration of 30 %mass and concentrated sulfuric acid in volume ratio of 1:4 are added to the flask, stirred for 3 hours, diluted with ultrapure water, allowed to stand for 24 hours to filter supernatant, washed several times, centrifuged, dried and ground to obtain functionalized Vulcan XC-72 (RTM: modified carbon powder). The functionalized Vulcan XC-72 (RTM: modified carbon powder), iridium precursor, nickel precursor, and sodium citrate in mass ratio of 1:0.1-2:0.05-1:0.2-2, respectively are added to deionized water and ultrasonic dispersion is carried out for 10-60 minutes to obtain uniform dispersion of functionalized Vulcan XC-72 (RTM: modified carbon powder) suspension. The obtained dispersion is stirred for 6-24 hours, 28 %mass aqueous ammonia is added to adjust pH value to 11-13, dried in 50-80 degrees C water bath and ground to obtain carbon-supported nickel complex of iridium. Hydrogen and argon in volume ratio of 1:1-8 are mixed with carbon-supported nickel complex of iridium at gas flow rate of 100-800 ml/minute, and heated at 300-700 degrees C for 1-3 hours. The heated mixture is cooled, washed with water and dried under vacuum to obtain carbon-nickel alloy-containing iridium catalyst. The concentration of functionalized Vulcan XC-72 (RTM: modified carbon powder) in the suspension is 3-25 g/l.
