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...
1. Graphene oxide was synthesized using the modified Hummers method5. First, the GO solution was drop-cast on a PET film and dried overnight. Subsequently, the as-prepared GO film was wetted with the zinc acetate precursor solution and rinsed with ethanol after 30 s. The wetting and ...
Improved synthesis of graphene oxide with controlled oxidation degree by using different dihydrogen phosphate as intercalators The controllable oxidation degree of graphene oxide (GO) by improving Hummers method are currently being addressed. In this work, Improved Hummers method w... S Shuai,Y ...
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 ...
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...
Figure 1. Synthesis of graphene oxide according to Hummer’s method modified. In the last few years, different GO syntheses have been developed using the modified Hummers method from commercial graphite, where variations are made to increase the number of oxygenated groups using different particle ...
