Comparison analysis of graphene oxide reduction methods

Graphene oxide was reduced by aspartic acid, beta-mercaptoethanol in the acidic mixture, hydrothermal method and by atomic hydrogen (deuterium and tritium). Raman spectroscopy and FTIR indicate high reduction efficiency of hydrothermal method. FTIR indicates that atomic hydrogen results in the formation Csp3H-bonds on the graphene surface. Graphene oxide can be effectively reduced by beta-mercaptoethanol in the acidic mixture even at room temperature.
