Outline of Final Research Achievements

A green method to synthesize the reduced graphene oxide using sub- and supercritical fluid has been developed, which is an environmentally friendly and a one step reduction process with efficient route. It was found that ethanol has higher reducing capability than other solvents such as CO2, hexane, acetonitrile, benzyl alcohol, methanol, ethanol, butanol and propanol examined in this study for graphene oxide reduction. It was found that substantial conversion of GO could be achieved in sub-critical condition of ethanol with HI at 300 C and 10 atm.
