NOVELTY - A molybdenum disulfide nanosheet/graphene composite nanomaterial comprises a layered structure of molybdenum disulfide nanosheet and graphene composite in a ratio of 1:1-1:4. USE - Molybdenum disulfide nanosheet/graphene composite nanomaterial. ADVANTAGE - The nanomaterial is prepared in a simple, convenient and easy manner with better industrialized applicability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing a molybdenum disulfide nanosheet/graphene composite nanomaterial, which involves ultrasonically dispersing the graphene oxide in deionized water, adding gemini surfactant to the dispersed oxide and fully stirring , adding L-cysteine and sodium molybdate to the stirred product, and fully stirring to dissolve, transferring the resulting product into a hydro-thermal reaction kettle at 230-250 degrees C under lower hydro-thermal reaction for 20-24 hours, naturally cooling to room temperature followed by centrifuging and collecting the solid product by water washing, drying and heat processing to obtain the finished product.
