NOVELTY - A carbon coated nickel oxide graphene nanocomposite material preparing method involves weighing 0.01-0.3 g bis(cyclopentadienyl) nickel and adding 8 ml anhydrous solvent. An ultrasonic process is preformed for 5 to 60 min. 1-5 ml graphene oxide is added to anhydrous solvent dispersion and ultrasonically dispersed. A mixed liquid is transferred with pressure kettle to an oven box and cooled. A liquid material is taken out and washed. The obtained reaction product is placed in a drying box under protecting gas, heated to 250-700 degrees C and cooled for 1-6 hours to obtain the finished product. USE - Method for preparing a carbon coated nickel oxide graphene nanocomposite material. ADVANTAGE - The method enables ensuring simple operation, low production cost, easy batch and large-scale production, good industrial production and wide application prospect. DETAILED DESCRIPTION - A carbon coated nickel oxide graphene nanocomposite material preparing method involves weighing 0.01-0.3 g bis (cyclopentadienyl) nickel and adding 8 ml anhydrous solvent. An ultrasonic process is preformed for 5 to 60 min. 1-5 ml graphene oxide is added to anhydrous solvent dispersion and ultrasonically dispersed for 10 to 120 min. A mixed liquid is transferred with pressure kettle to an oven box at 100-250 degrees C for 2-36 hours, and cooled at room temperature. A liquid material is taken out and washed using anhydrous ethyl alcohol for 3-10 times. The obtained reaction product is placed in a drying box under protecting gas, heated to 250-700 degrees C and cooled for 1-6 hours to obtain the finished product.
