▎ 摘　　要

NOVELTY - The method involves absorbing high-conductivity carbon quantum material in oxygen-free sealed microwave radiation environment, generating local high temperature and local plasma, which can enhance the front end of the microwave induced metal wire array fast discharge, generating high density and persistent electric explosion, where the raw material containing carbon is at high temperature, in the plasma flow environment with high activity, the carbon atom is reduced, after gasification, the graphene is formed, the technology using microwave to induce metal to generate high temperature. USE - Method for preparing graphene by catalyst auxiliary microwave excited metal discharge. Uses include but are not limited to integrated circuit, battery energy, electrode material and other fields. ADVANTAGE - The method uses carbon source with low cost as raw material, replacing expensive, chemical method for preparing graphite oxide, solves the problem of high energy consumption, at the same time, microwave device price is far lower than the high voltage pulse power supply device, which not only realizes the low cost of manufacturing graphene, but also can be produced in large scale, and has market competitiveness. The catalyst absorbs microwave to form local high temperature and local plasma, the front end of the microwave induced metal wire array can be enhanced fast discharge, generating high density, persistent electric explosion, the high temperature, high chemical activity of the plasma quickly converts the carbon source into graphene.
