The invention discloses a nitrogen-doped graphene-confined Pt nanocomposite material, a preparation method and an application thereof. The nitrogen-doped graphene-confined Pt nanocomposite is CN@Pt / GO; firstly, Pt nanoparticles are directly loaded on graphene by wet chemical reduction method to obtain Pt / GO; then, by CVD method, the Pt / GO prepared by rapidly depositing a nitrogen-doped graphene layer on the surface of Pt nanoparticles. The CN@Pt / GO prepared by the present invention exhibits better catalytic performance for low-temperature oxidation of CO. Due to the confinement of Pt nanoparticles and graphene and nitrogen-doped graphene, the electron density of supported Pt nanoparticles is increased, and the desorption of CO is enhanced, so that the low-temperature catalytic performance of CN@Pt / GO for CO is better than that of Pt / GO. Thus, the CO low-temperature catalytic performance of the CN@Pt / GO catalyst was improved.
