Abstract
Disclosed are methods for preparing pure graphene using chemical bonding between graphite oxide and metal oxide nanoparticles, and graphene and nanoparticles having a quasi metal oxide-graphene core-shell prepared therefrom. The disclosed methods for preparing graphene allow chemical bonding and separation through a simple acid treatment process using inexpensive materials. Also, because the reaction can be carried out at low temperature, the processing cost is low. And, pure graphene with few impurities can be prepared quickly in large scale.
