NOVELTY - Preparing metal structure molybdenum diselenide/redox graphene composite powder involves hydrothermally heating an aqueous solution containing selenium ions, ammonium paramolybdate, citric acid, and graphene oxide for the reaction, where reaction conditions are room temperature for 10-12 hours, and then the temperature is raised to 160 degrees C for 18-24 hours to obtain metal structure molybdenum diselenide/redox graphene composite powder. USE - Method for preparing metal structure molybdenum diselenide/redox graphene composite powder. ADVANTAGE - The method enable to preparing metal structure molybdenum diselenide/redox graphene composite powder in a simple and cost-effective manner, shows small energy consumption and high efficiency and adds Reduced Graphene Oxide (RGO) with doped copper ions further improves the performance of the material.
