A Low-Cost Non-explosive Synthesis of Graphene Oxide for Scalable Applications

Abstract A low cost, non-explosive process for the synthesis of graphene oxide (GO) is demonstrated. Using suitable choice of reaction parameters including temperature and time, this recipe does not require expensive membranes for filtration of carbonaceous and metallic residues. A pre-cooling proto...
