Graphite oxide was obtained using the Hummers’ method and the material was exfoliated into monolayers by short-duration sonication in water (3 minutes under 40 W power). Large monolayers (>10–20 µm) were separated from smaller ones using centrifugation procedures30. The chemical composi...
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 perfor...
In this work, we present the effect of initial graphite particle size and shape on oxidation time in graphene oxide prepared by Hummers' method. This helps control the oxidation producer, which can be useful in large scale production of graphite oxide. 2. Experimental 2.1. Materials Experiments ...
Graphite oxide has attracted much interest as a possible route for preparation of natural graphite in the large-scale production and manipulation of graphene as a material with extraordinary electronic properties. Graphite oxide was prepared by modified Hummers method from purified natural graphite sample...
In the present study, clay – graphene oxide nanocomposite catalysts were successfully used for the first time in the multicomponent one pot organic synthesis. The facile development of the hybrid clay – graphene oxide nanocomposite has been achieved by a cost-effective method without the use of ...
Graphene oxide is highly desired for printing electronics, catalysis, energy storage, separation membranes, biomedicine, and composites. However, the present synthesis methods depend on the reactions of graphite with mixed strong oxidants, which suffer f
