NOVELTY - 10-500 mg Graphene oxide nanosheet is weighed, and deionized water is added and ultrasonically dispersed at 250 W. 10-1000 mg Salt(s) of transition metal compound, 5-100 mg sodium citrate and 10-500 mg hexamethylenetetramine are sequentially added to resultant mixture, reacted by stirring at 80-90 degrees C for 2-12 hours at 400 rpm, and the obtained product is centrifuged, washed 1-10 times with ethanol and dried. Resultant product is calcined at 250-450 under nitrogen atmosphere. Thus, transition metal nanosheet is grown on the graphene surface. USE - Method of growing transition metal nanosheet on graphene surface (claimed). ADVANTAGE - The method efficiently provides transition metal nanosheet-containing graphene surface having high specific surface area and supercapacitor property than general nano electrochemical material. DETAILED DESCRIPTION - 10-500 mg Graphene oxide nanosheet is weighed, and 10-500 ml deionized water is added and ultrasonically dispersed for 1-60 minutes in the ultrasonic power of 250 W. 10-1000 mg Salt(s) of transition metal compound, 5-100 mg sodium citrate and 10-500 mg hexamethylenetetramine are sequentially added to the resultant mixture, reacted by stirring at 80-90 degrees C for 2-12 hours at 400 rpm, and the obtained product is centrifuged, washed 1-10 times with ethanol and dried. The salt of transition metal compound is chosen from nickel nitrate hexahydrate, cobalt nitrate hexahydrate, zinc nitrate hexahydrate and manganese nitrate hexahydrate. The resultant product is calcined in a tubular furnace at 250-450 degrees C for 1-4 hours under nitrogen atmosphere at the heating rate of 1-5 degrees C/minute. Thus, transition metal nanosheet is grown on the graphene surface.
