NOVELTY - Preparation of graphene/platinum (Pt) nano composite material comprises adding dispersant and graphite oxide in deionized water, adding reducing agent, heating in oil bath, and stirring to obtain graphene oxide solution, where mass ratio of graphite to reducing agent is 1:5-1:10 and that of graphite oxide to dispersant is 1:5-1:10; dissolving graphite precursor and molybdenum in solvent, mixing, and adjusting pH to 8-12, where mass ratio of graphite oxide to molybdenum is 1:1-10:1; and heating in oil bath at 110-120 degrees C for 0.5-4 hours, incubating for 2-8 hours, filtering, freezing and drying. USE - Method for preparing graphene/Pt nano composite material (claimed). ADVANTAGE - The method has low requirement of production equipment. The material has small size and is not easy to reunite.
