What is reduced graphene oxide used for?
What is reduced graphene oxide used for?
Reduced graphene oxide (rGO) has commonly been used to prepare composites with various materials, such as metal and metal oxides, by utilizing different techniques to improve the supercapacitor performance.
What is the difference between graphene oxide and reduced graphene oxide?
According to the IUPAC definition, “graphene is a single carbon layer of graphite structure, describing its nature by anology of a polycyclic aromatic hydrocarbon of quasi-infinite size”. However, Reduced graphene oxide is prepared from reduction of graphene oxide by thermal, chemical or electrical treatments.
Is reduced graphene oxide toxic?
Recent studies also have shown that rGO is likely to be toxic and could integrate cell membranes and induce programmed cell death in a dose-dependent manner, particularly in concentrations higher than 50 μg ml−1 [11–13].
How do you prepare reduced graphene oxide?
Synthesis of Reduced Graphene Oxide (RGO) The RGO was prepared by dispersing 400 mg XGO into 800 mL of distilled water while stirring and heating at 95°C for 4 days.
What are the applications of graphene oxide?
In solid form, Graphene Oxide flakes attach one to another to form thin and stable flat structures that can be folded, wrinkled, and stretched. Such Graphene Oxide structures can be used for applications like hydrogen storage, ion conductors and nanofiltration membranes.
Why graphene oxide is used instead of graphene?
Graphene Oxide is cheaper and easier to manufacture than graphene, and so may enter mass production and use sooner. GO can easily be mixed with different polymers and other materials, and enhance properties of composite materials like tensile strength, elasticity, conductivity and more.
How do you clean graphene oxide?
Usully, GO can be washed using HCl and DI water with vacuum filtration. When the degree of oxidation of GO is high, GO present very good hydrophilicity, vacuum filtration may could not drew water out from GO suspension.
Is graphene oxide magnetic?
Magnetic graphene oxide, a compound of magnetic nanoparticles and graphene oxide, possesses distinct physical and chemical characteristics, including nano size, a large specific surface area, paramagnetic and biocompatible properties, making it a promising biomaterial in the field of biomedicine.
Why do we reduce graphene oxide?
It is important to reduce the graphene oxide so as to recover the honeycomb hexagonal lattice of graphene, in order to restore electrical conductivity . After a large number of oxygen groups have been removed, it is not easy to disperse the reduced graphene oxide (rGO), because this material tends to produce aggregates.
What is meaning of reduction of graphene oxide?
Reduction of graphene oxide means deoxygenation of graphene oxide(GO) via chemical and physical processes.Graphene oxide is a product of oxidation and exfoliation of graphite(G).Graphite has high…
Is graphite oxide the same as graphene oxide?
Graphite oxide and graphene oxide are very similar , chemically, but structurally, they are very different. The main difference between graphite oxide and graphene oxide is the interplanar spacing between the individual atomic layers of the compounds, caused by water intercalation.
What is the actual colour of graphene oxide?
the color of pure graphene oxide is brown and if your product is not brown than it means graphene oxide is not formed. The graphene oxide aqueous solution is usually of yellowish to brown color. However, if the graphene oxide got somewhat reduced, its color will become black, always with degenerated solubility as well. Therefore,
