Abstract

It was shown that the structure of graphite oxide is formed in two stages. The first is hydroxylation of the graphene layers to a level of 4–6 hydroxyls to one coronene fragment (C24). The second is the accumulation of hydroxyl, peroxide, and hydroperoxide groups, accompanied by strong dearomatization of the graphene structure. Epoxide groups, previously considered some of the main oxygen-containing functional groups in graphite oxide, were not detected.
