What is the difference between graphene graphene oxide and reduced graphene oxide?

The key difference between graphene oxide and reduced graphene oxide is that the graphene oxide contains oxygen-containing functional groups whereas the reduced graphene oxide lacks the oxygen-containing functional groups. Graphite oxide is a material that consists of carbon, hydrogen and oxygen atoms.

How do you convert graphene oxide to graphene?

Chemically converted graphene has been synthesized via the reduction of graphene oxide by using organic bases, including 1,8-diazoicyclo (5, 4, 0) undecene-7, triethylamine and 1,4-diazobicyclo (2, 2, 2) octane, as the reducing agent.

Why reduced graphene oxide is better than graphene oxide?

Xiao Fan The only big difference between GO and rGO is the number of oxygen molecules present, hence conductivity. GO in an insulator, while rGO is electrically conductive, but also the conductivity depends on the degree of reduction. Highly reduced rGO is almost a superconductor, just like pure graphene.

How do you oxidize graphene?

The oxidized graphene (OG) was obtained by oxidizing the graphene via a simplified Hummer’s method, which begins by mixing 1 g of graphene, 30 ml of H2SO4 (98%) and 10 ml of HNO3 (98%) in a 1000 ml volumetric flask that was stirred continuously for 2 h.

Which is better graphene or graphene oxide?

One of the most important differences between GO and rGO is the electrical conductivity of these materials. While GO shows insulating or semi-conducting behavior rGO shows excellent electrical conductivity which is almost as good as pristine graphene.

How do you reduce go to RGO?

The graphene oxide (GO) was converted to reduced graphene oxide (rGO) by chemical reduction using ascorbic acid as the reducing agent. The GO and rGO were characterized by UV-visible spectroscopy, FTIR spectroscopy, and X-ray diffraction patterns.

Why is graphene oxide reduced?

2.3 Reduced graphene oxide (rGO) Reduced graphene oxide (rGO) is an alternative form of GO which has been processed by various methods which include chemical, thermal, etc. in order to minimize the amount of oxygen as the oxygen content makes GO more unstable [75].

What is reduced graphene oxide?

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.

Can graphene be oxidised?

Graphene oxide is an oxidized form of graphene, laced with oxygen-containing groups. It is considered easy to process since it is dispersible in water (and other solvents), and it can even be used to make graphene.

How is graphene oxide reduced?

GO can be reduced solely by heat treatment and the process is named thermal annealing reduction. In the initial stages of graphene research, rapid heating (>2000 °C/min) was usually used to exfoliate graphite oxide to achieve graphene [35], [45], [74], [75].
