| titleOfInvention | A kind of preparation method of graphene composite petroleum coke-based activated carbon and super capacitor |
| abstract | The invention provides a preparation method of graphene composite petroleum coke-based activated carbon. First, the petroleum coke particles are coked under the condition of a first gas to obtain pre-carbonized petroleum coke; and then the pre-carbonized petroleum coke is mixed with an activator. , activate under the condition of the third gas, and then wash to obtain an activated carbon dispersion; then mix the activated carbon dispersion, graphene oxide solution and reducing agent for chemical reduction, and obtain a semi-finished product; finally, the semi-finished product is etched by an etchant After post-drying, and then heat treatment under the condition of protective gas, the graphene composite petroleum coke-based activated carbon is obtained. In the present invention, hydrogen peroxide is used for etching treatment, so that the graphene is further formed with pores, the ion migration channel is improved, and the specific surface area of the graphene modified activated carbon is further increased and stabilized. In the subsequent high-temperature reduction process, the graphene The structure is restored and the electrical conductivity of the activated carbon is improved, thereby increasing the specific capacity of the supercapacitive carbon. |
