Graphite oxide is a covalent compound, which can be synthesized in aqueous solution of sulfuric acid with strong oxidants, such as nitric acid and potassium permanganate. It contains oxygen and hydroxide radicals in various amounts, which make covalent bonds with carbon and, as a consequence, the layer of carbon atoms is not flat. Instead Graphene oxide is the bulk form of graphite oxide, is a two-dimensional material derived from graphene, and has the ability to remain exfoliated in water as single atomic layers sheets
