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.
What is graphene oxide and 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.
What happens when graphene oxide is reduced?
Graphene oxide is a form of graphene that includes oxygen functional groups, and has interesting properties that can be different than those of graphene. By reducing graphene oxide, these oxidized functional groups are removed, to obtain a graphene material.
What is difference between graphene and graphene oxide?
Graphite is a layer structure and a single layer of graphite is called as graphene. When the single layer of graphite contains some oxygen functionalities then it is called graphene oxide .
What is difference between rGO and go?
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.
What is graphene oxide?
Graphene oxide (GO), an oxidized derivative of graphene, is currently used in biotechnology and medicine for cancer treatment, drug delivery, and cellular imaging. Also, GO is characterized by various physicochemical properties, including nanoscale size, high surface area, and electrical charge.
How can graphene oxide be reduced from 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.
Is reduced graphene oxide water soluble?
Conclusions. In summary, we demonstrate that water soluble reduced graphene oxide can be synthesized via a two-step reduction approach assisted with sulfonation. The obtained rGO is typically 2 nm in thickness and most of the oxygen-related groups are removed by reduction.
How can graphene oxide be reduced in the body?
Graphene Oxide to Reduced Graphene Oxide
- Treating GO with hydrazine hydrate and maintaining the solution at 100 for 24 hours.
- Exposing GO to hydrogen plasma for a few seconds.
- Exposing GO to another form of strong pulse light, such as those produced by xenon flashtubes.
Why is graphene oxide better than 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.
What is another name for graphene oxide?
Description Graphene oxide (GO), also referred to as graphite/graphitic oxide, is obtained by treating graphite with oxidisers, and results in a compound of carbon, oxygen, and hydrogen in variable ratios.
Is graphene stronger than graphite?
Although graphite is often used to reinforce steel, it cannot be utilized as a structural material on its own because of its sheer planes. In contrast, graphene is the strongest material ever found; it is more than 40 times stronger than diamond and more than 300 times stronger than A36 structural steel.
Which is more conductive go or rGO?
The most important difference is considered to be the electrical conductivity of these two materials. While GO show insulating or semi-conducting behavior, rGO shows high electrical conductivity 6300 S cm−1.
Is graphene oxide a semiconductor?
Graphite oxide itself is an insulator, almost a semiconductor, with differential conductivity between 1 and 5×10−3 S/cm at a bias voltage of 10 V.
What are graphene Nanoplatelets?
Graphene nanoplatelet aggregates are aggregates of sub-micron platelets with a diameter of <2 microns and a thickness of a few nanometers, a bulk density of 0.2 to 0.4 g/cc, an oxygen content of <2 wt% and a carbon content of >98 wt%, and are offered as black granules or black powder.
How strong is graphene oxide?
Mechanical Strength
Due to the strength of its 0.142 Nm-long carbon bonds, graphene is the strongest material ever discovered, with an ultimate tensile strength of 130,000,000,000 Pascals (or 130 gigapascals), compared to 400,000,000 for A36 structural steel, or 375,700,000 for Aramid (Kevlar).
How do you detect graphene oxide?
Just one drop of blood for a diagnosis
A single drop of blood or saliva is all it takes to perform an accurate analysis. Just a few minutes after the drop is applied to the sensor’s surface, electrical signals convey the test result to the family doctor’s office.
Is graphene oxide organic or inorganic?
Carbon nanotubes, fullerene, graphene and graphene oxide are allotropes of carbon, such as diamond, and therefore are not considered organic either.
How do you get graphene from graphene oxide?
Generally, graphene was obtained by either refluxing the graphene oxide solution in a long time (about 24 h) [11] or heated the graphene oxide powder at high temperature (up to 1050 °C) under nitrogen atmosphere [12], [13].
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 graphene is used in nanotechnology?
Since graphene is just a single layer of carbon atoms connected in a hexagonal pattern, it is also extremely thin and lightweight, and therefore an attractive material for nanotechnology applications.
