USE - Preparation of heteroatom-doped graphene-based material noble metal nanoparticles used for catalyst. ADVANTAGE - The method enables simple and economical preparation of heteroatom-doped graphene-based material noble metal nanoparticles having excellent synergistic effects. The catalyst using the nanoparticles has excellent stability and activity. DETAILED DESCRIPTION - Preparation of heteroatom-doped graphene-based material noble metal nanoparticles involves subjecting graphene-based material to ultrasonic treatment, providing graphene-based material and heteroatom precursor in a reactor, reacting at 150-200 degrees C for 1-24 hours, obtaining heteroatom-doped graphene-based material, dissolving obtained material in deionized water, adding stabilizer and metal precursor, adjusting pH to 8-14, adding a reducing agent in mass ratio of resultant product and reducing agent of 1:1-100, stirring for 1-5 hours, and vacuum-drying. The mass ratio of graphene and heteroatom precursor is 1:1-10. The heteroatom is nitrogen, boron, phosphorus, sulfur and/or fluorine. The mass ratio of heteroatom-doped graphene-based material and stabilizer is 1-1:1-10. The metal of metal precursor is platinum, palladium, gold, or silver. The reducing agent is potassium borohydride, sodium borohydride or hydrazine hydrate.
