An improved method for the preparation of graphene oxide (GO) is described. Currently, Hummers’ method (KMnO 4, NaNO 3, H 2 SO 4) is the most common method used for preparing graphene oxide.We have found that excluding the NaNO 3, increasing the amount of KMnO 4, and performing the reaction in a 9:1 mixture of H 2 SO 4 /H 3 PO 4 improves the efficiency of the oxidation process.Cited by: 8216

https://patents.google.com/patent/US20180029887A1/en

Graphene oxide is synthesized by chemical treatment of graphite using only H 2 SO 4 , KMnO 4 , H 2 O 2 and/or H 2 O as reagents. Graphene oxide films obtained using the method disclosed herein were characterized using various analytical techniques. These analytical techniques confirmed the creation of single to few layer graphene oxide with relatively large lateral size distribution using the ...Cited by: 2

Mechanism of Graphene Oxide Formation ACS Nano

https://pubs.acs.org/doi/10.1021/nn500606a

Despite intensive research, the mechanism of graphene oxide (GO) formation remains unclear. The role of interfacial interactions between solid graphite and the liquid reaction medium, and transport of the oxidizing agent into the graphite, has not been well-addressed. In this work, we show that formation of GO from graphite constitutes three distinct independent steps.
