NOVELTY - Method for preparing molybdenum disulfide nanosheet composite graphene, involves (i) adding molybdenum source to water to obtain a solution (A), (ii) adding sulfur source to water to obtain a solution (B), (iii) dispersing graphene in water to form a solution (C), (iv) mixing the solutions (A), (B) and (C), completely stirring, transferring to an 80 ml PTFE high pressure reaction kettle for sealing, transferring the reaction kettle to an oven, setting the temperature at 160-200 degrees C and reacting for 12-24 hours, and cooling to room temperature to obtain a suspension, and (v) centrifuging and washing the suspension obtained in step (iv) with deionized water for 5-6 times, and drying the centrifugal product in a freeze-dryer to obtain the molybdenum disulfide composite graphene material powder. USE - The method is useful for preparing molybdenum disulfide nanosheet composite graphene for electrochemical energy storage. ADVANTAGE - The method uses simple equipment and low raw material price, and has non-toxicity.
