Abstract

The invention discloses a metal graphene composite as well as a preparation method and device thereof. The composite is prepared from the following raw materials: copper foil, dilute hydrochloric acid, hydrogen, methane, PMMA, a FeCl3 solution, deionized water, carbon aerogel, a metal-containing chemical plating solution, acetone and inert gas. The preparation method comprises the following steps:preparing nano porous metal, fishing out graphene from deionized water by using the nano porous metal, and placing the graphene into a drying oven for heating to obtain the metal graphene composite.According to comparison between graphene with metal support and graphene without metal support by experiments, metal graphene prepared with the preparation method of the metal graphene composite has the advantages that graphene with metal support has obviously improved specific capacity and better electrochemical performance, and has better effect as an electrode of a supercapacitor.

Description

technical field [0001] The invention relates to the technical field of carbon processing, in particular to a metal-graphene composite material, a preparation method and a preparation device thereof. Background technique [0002] Carbon materials were the first to be used as electrode materials for supercapacitors, and they have the advantages of good stability, good electrical conductivity, and high specific surface area. Since the carbon material forms an electric double layer capacitance on its surface, the larger the specific surface area of ​​the material, the better the capacitance performance of the capacitor. Therefore, increasing the specific surface area of ​​the carbon material is an effective way to increase the specific capacity of the carbon electrode material capacitor. Graphene is a two-dimensional sheet structure, the thickness is only one carbon atom thick, and the surface is a hexagonal network structure composed of carbon atoms. Graphene has special physi...
