The generated graphene in liquid Argon was purer and less defect because of Lack of reactivity of argon. However, graphene doped nitrogen is generated in nitrogen liquid because of reactivity of nitrogen. Also graphene structure has Advantages such as easy sample collection, lower production costs and a single stage of production rather than the other way Graphene is produced.
