NOVELTY - The method for controlling synthesis of high quality graphene by chlorination of two-dimensional carbide crystal involves introducing chlorine gas into two-dimensional carbide crystal at certain temperature, and obtaining graphene by etching reaction of chlorine gas with two-dimensional carbide. USE - Method for controlling synthesis of high quality graphene by chlorination of two-dimensional carbide crystal (claimed). ADVANTAGE - The method enables synthesis of high quality graphene with wide range of raw materials at low cost under mild conditions, and completely chlorinates two-dimensional carbides to graphene.
