Alok Mani Tripathi

Go for Hummers method followed by chemical/thermal reduction

Manohar Sehgal

I agree with Alok but with one change. Better prepare GO by the improved Hummer method (the graphite flakes are oxidized by KMO4 and a mixture of H2SO4& H3PO4 which produces no toxic gases like NO2, N2O4 or ClO2 and produce better quality product wrt size/ time duration of oxidation under conrolled reaction conditions) which is easier to reduce.
