MANGANESE OXIDE/GRAPHENE COMPOSITE AND PRODUCING METHOD OF THE SAME

摘要

PURPOSE: A manganese oxide / graphene nanocomposite is provided to easily synthesize thereof through an aqueous phase reaction at a room temperature without special equipment, a material, or a surfactant. CONSTITUTION: A manufacturing method of a manganese oxide / graphene nanocomposite comprises following steps. A reacting solution is obtained by reacting a manganese precursor and a graphene colloid. An oxidant is reacted in the reacting solution. A reaction of the graphene colloid and the manganese precursor is performed in 0-50°C. The manganese precursor comprises a precursor containing manganese in a divalent state. The oxidant is selected in a group comprising (NH4) 2S2O8, li2S2O8, na2S2O8, K2S2O8 and a combinations thereof. The oxidant is added to the manganese precursor as a mole ratio of 1:1-5. The graphene comprises a pure graphene, and a RGO (reduced graphene oxide) or a combination thereof. The manganese oxide / graphene nanocomposite is included in the electrode material or the electrode for the super capacitor.
