NOVELTY - Preparation of graphene load type nickel-molybdenum core-shell nanocomposite involves mixing graphite and sodium nitrate in mass ratio of 1-3:0.5-1.5 in a three-neck flask under ice bath condition, slowly adding concentrated sulfuric acid and potassium permanganate, where ratio of graphite and concentrated sulfuric acid is 1-3:10-90, and mass ratio of graphite and potassium permanganate is 1-3:1-10, heating, continuously stirring and adding potassium permanganate, adding ice high pure water to dilute to room temperature, and then adding 30 %mass hydrogen peroxide. USE - Preparation of graphene load type nickel-molybdenum core-shell nanocomposite (claimed). ADVANTAGE - The method efficiently and economically provides graphene load type nickel-molybdenum core-shell nanocomposite, using simple process in short period of time. DETAILED DESCRIPTION - Preparation of graphene load type nickel-molybdenum core-shell nanocomposite involves mixing graphite and sodium nitrate in mass ratio of 1-3:0.5-1.5 in a three-neck flask under ice bath condition, slowly adding concentrated sulfuric acid and potassium permanganate, where ratio of graphite and concentrated sulfuric acid is 1-3:10-90, and mass ratio of graphite and potassium permanganate is 1-3:1-10, heating to 30-50 degrees C for 5-15 hours, continuously stirring and adding potassium permanganate, adding ice high pure water to dilute to room temperature, then adding 30 %mass hydrogen peroxide, such that the mass ratio of graphite and hydrogen peroxide is 1-3:1-5 and obtaining graphene oxide, washing product using deionized water, concentrated hydrochloric acid and absolute ethyl alcohol, filtering, drying, adding graphene oxide into ethylene glycol solution, ultrasonically-dispersing, and adjusting pH of solution to 7-13, adding chloroplatinic acid and mechanically-stirring at room temperature for 20-30 hours.
