GO mainly contains different functional groups that reduce its conductivity compared to RGO. On the other hand in RGO percentage of oxygen-containing functional groups reduced and the percentage of SP2 carbon atoms increases which increase its conductivity. There are several techniques for the reductions of GO to RGO.

What is the difference between graphene and graphene oxide?

What's the difference between graphene and graphene oxide? Graphene oxide, as the name suggests, is a graphene layer containing oxygen and oxygen-bearing groups (O, OH etc.). In order to maintain the uniform structure of graphene, the oxide form may not be produced through oxidation, but rather by reduction.

Why is graphene oxide reduced?

Reduced graphene oxide (RGO) is the form of GO that is processed by chemical, thermal and other methods in order to reduce the oxygen content, while graphite oxide is a material produced by oxidation of graphite which leads to increased interlayer spacing and functionalization of the basal planes of graphite.

How can graphene oxide be reduced?

Graphene Oxide to Reduced Graphene Oxide

What is graphene oxide used for?

Graphene oxide could potentially be used as an intermediary in the production of single layer or few-layer graphene sheets. To achieve this, an oxidization and reduction process should be developed that can isolate carbon layers and separate then without changing their structure.

What is the color of graphene?

the color of pure graphene oxide is brown and if your product is not brown than it means graphene oxide is not formed.

What is the chemical formula for graphene?

Graphene oxide, powder, 15-20 sheets, 4-10% edge-oxidized

How do you convert graphene oxide to graphene?

Well, actually graphene is obtained from graphene oxide, NOT vice versa! We oxidize graphite via different methods, which I personally have used modified hummers' method (Chem. Mater. 2010, 22, 1392–1401), then you can reduce graphene oxide to get graphene.

Why Graphene oxide is hydrophilic?

However, graphene oxide nanosheets are hydrophilic in nature and are not dispersible in organic solvents. We prepared hydrophobic graphene oxide nanosheets by reacting them with phenylisocyanate (C6H5NCO). The phenylisocyanate molecule contains a non-polar benzene group.

What are Graphenes properties?

Graphene possesses other amazing characteristics: Its high electron mobility is 100x faster than silicon; it conducts heat 2x better than diamond; its electrical conductivity is 13x better than copper; it absorbs only 2.3% of reflecting light; it is impervious so that even the smallest atom (helium) can't pass through ...

How do you synthesis graphene oxide?

Hummer's method of synthesis

Graphene oxide was synthesized by Hummers method through oxidation of graphite. The stepwise preparation is given as follows: 1. Graphite flakes (2 g) and NaNO3 (2 g) were mixed in 50 mL of H2SO4 (98%) in a 1000 mL volumetric flask kept under at ice bath (0-5°C) with continuous stirring.

Is reduced graphene oxide hydrophobic?

Graphene is usually a hydrophobic material, that is why it settles down after the completion of the reduction process, we will use some dispersive agents to make it disperse in water, but some papers reported that graphene is hydrophobic (graphene dispersed well without the use of any dispersing agent).

How do you make graphite?

Synthetic graphite is a material consisting of graphitic carbon which has been obtained by graphitizing of non-graphitic carbon, by CVD from hydrocarbons at temperatures above 2500 K, by decomposition of thermally unstable carbides or by crystallizing from metal melts supersaturated with carbon.
