NOVELTY - Preparing spherical graphene particle involves dispersing graphene oxide in a solvent, adding a reducing agent to the graphene oxide dispersion and heating and reducing it while irradiating with microwaves, and spray-drying the reduced graphene dispersion to obtain spherical graphene particles. USE - Method for preparing spherical graphene particle used for electrode material which is used for an energy storage device (claimed), and used in environmental fields such as water treatment, odor and toxic gas removal by utilizing porous adsorption properties. ADVANTAGE - The prepared particle has high-density, and prepared in simple manner.
