NOVELTY - Preparing activated carbon surface rich petal-shaped graphene comprises taking mesocarbon microbeads powder and potassium hydroxide flakes into nickel crucible, adding deionized water to dissolve, adding anhydrous ethanol solution, stirring, dissolving the solution, drying to obtain mesocarbon microbeads and potassium hydroxide mixed powder, subjecting to high temperature activation treatment in a nickel crucible of a tubular furnace, heating under the argon atmosphere, cooling, washing with diluted hydrochloric acid, filtering under vacuum and drying. USE - The activated carbon surface rich petal-shaped graphene is useful in developing multifunctional supported nano-active particles and multi-functional carbon material for adsorption, catalyst support, hydrogen storage, super capacitor and lithium sulfur batteries. ADVANTAGE - The method: utilizes easily available raw material sources; and is simple and economical. DETAILED DESCRIPTION - Preparing activated carbon surface rich petal-shaped graphene comprises (a) taking mesocarbon microbeads powder and potassium hydroxide flakes in a mass ratio of 1:(3-10) into nickel crucible, adding deionized water to dissolve potassium hydroxide to form a solution, (b) adding anhydrous ethanol solution, stirring with a glass rod, (c) completely dissolving the solution to be refined, drying in a constant temperature drying box to obtain mesocarbon microbeads and potassium hydroxide mixed powder, (d) subjecting the mixed powder to high temperature activation treatment by taking the mixed powder into a nickel crucible of a tubular furnace, heating from room temperature to 900-1200 degrees C at a rate of 5 degrees C/minute under the argon atmosphere, maintaining the temperature for 1-2 hours and naturally cooling along with the furnace, and (e) washing obtained activated powder with diluted hydrochloric acid, filtering under vacuum and drying at constant temperature.
