Comparative study of different scalable routes to synthesize graphene oxide and reduced graphene oxide

Graphene oxide is considered one of the most significant material due to its capability of be a reliable and potentially scalable precursor of graphene. Several processes of graphene mass production are getting involved into very polluting oxidants, toxic gases emissions, explosions and deflagration...
