Synthesis of Graphene Oxide (GO) by Modified Hummers ...

Initially graphite oxide was prepared by oxidizing the purified natural flake graphite (NFG) by the modified Hummers method. Thereafter, graphene oxide (GO) was pre- pared by the exfoliation of the graphite oxide in distilled water in an ultrasonicator. GO was later reduced thermally to obtain reduced graphene oxide (rGO).
