A method for controlling an amount of epoxy groups introduced into a graphene oxide of the present invention comprises following steps of: a) mixing graphene with peracetic acid to prepare a mixture; and b) introducing an epoxy group into the graphene by irradiating microwave to the mixture. ...
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 from explosion risk, serious environmental pollution, ...
While the production of graphene oxide (GO) and reduced graphene oxide (rGO) have been typically created from synthetic and flake graphite, high purity natural vein graphite has yet to be utilized fully. Therefore, the objective of the present study was to synthesize GO and rGO from high purit...

Graphene oxide (GO) is a derivative of graphene that consists of highly oxygen-containing functional groups on their basal planes and edges that can be synthesized by chemical oxidation of graphite. From:Synthesis, Technology and Applications of Carbon Nanomaterials,2019 ...
Functionalized graphene oxide (GO)/SiO2nanocomposites (FGS) was successfully fabricated by two steps; the first one was the combustion of RHP in covered crucible inside stainless steel autoclave at three different temperature, 400, 500, and 600 °C at 1 h for obtaining ash RHA1, RHA2, and ...
Graphene oxide/gold nanorod (GO/GNR) nanohybrids were synthesized with a GO- and gold-seed-mediated in situ growth method at room temperature by mixing polystyrene sulfonate (PSS) functionalized GO, secondary growth solution, and gold seeds. Compared with ex situ preparation methods of GO/GNRs or...
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...
synthesis route and the material used as carbon source. In addition, highly oxidized fragments, called oxidative debris, OD, are produced during theoxidation process. These fragments are adsorbed onto the graphene oxide network and can be removed by alkaline washing. The purified material has lower...
Synthesis of the coating material with magnetic nanoparticles (MNPs) is one of the vibrant areas of the implication of magnetic nanoparticles. Metallic MNPs could not be used much for surface coating materials due to their easy oxidation nature [16]. Utilization of an oxide magnetic nanoparticle ...
