USE - The composite material is useful as an electrochemical lithium-stored electrode material, an electrochemical magnesium-stored electrode material and a catalyst carrier. ADVANTAGE - The composite material can be prepared in a simple manner with moderate reaction condition. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the composite material of the graphene nanometer sheet/molybdenum disulfide graphene nanometer sheet, comprising (i) preparing oxide graphite nanometer by dispersing graphite powder (0.015-0.12 g) to concentrated sulfuric acid (20-25 ml) at ice bath of 0 degrees C, stirring and adding potassium permanganate, which is 3-4 times the mass of graphite, stirring for 30-60 minutes, heating to 30-35 degrees C, adding de-ionized water (46 ml), stirring for 20-30 minutes, adding hydrogen peroxide (10 ml) having = mass concentration of 30%, stirring for 5-10 minutes, centrifuging and separating, and repeatedly cleaning with 5% hydrochloric acid solution, de-ionized water and acetone to obtain graphite oxide nanometer sheet, and (ii) forming 0.02-0.10 M solution by dissolving molybdate in water, adding thioacetamide or thiourea used as a sulfur source and a reducing agent, where the mass ratio of thioacetamide or thiourea to molybdate is 5:1-8:1, adding a certain amount of glucose, where the mass ratio of glucose to molybdate is 4.5:1-13.4:1, adding the graphite oxide nanometer sheet obtained in step (i) to the solution, where the mass ratio of the graphite used in step (i) to the molybdate is 1:1-1:4, supersonically treating for 1-2 hour so that the graphite oxide nanometer sheet is fully dispersed in the hydrothermal reaction solution, sealing the mixture in a hydrothermal reactor interlined with Teflon (RTM: Polytetrafluoroethylene), carrying out hydrothermal reaction at 200-240 degrees C for 20-36 hours, centrifuging and separating the product, cleaning and drying the intermediate product with de-ionized water and absolute ethyl alcohol, and thermally treating at 800-1000 degrees C for 2 hours in an atmosphere of 90% nitrogen and 10% hydrogen.
