Graphene Oxide: Introduction and Market News

What is Graphene Oxide?

Graphene is a material made of carbon atoms that are bonded together in a repeating pattern of hexagons. Graphene is so thin that it is considered two dimensional. Graphene is considered to be the strongest material in the world, as well as one of the most conductive to electricity and heat. Graphene has endless potential applications, in almost every industry (like electronics, medicine, aviation and much more).

As graphene is expensive and relatively hard to produce, great efforts are made to find effective yet inexpensive ways to make and use graphene derivatives or related materials. Graphene oxide (GO) is one of those materials - it is a single-atomic layered material, made by the powerful oxidation of graphite, which is cheap and abundant. 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. Graphene oxide is not a good conductor, but processes exist to augment its properties. It is commonly sold in powder form, dispersed, or as a coating on substrates.

Graphene Oxide vs Graphene scheme

Graphene oxide is synthesized using four basic methods: Staudenmaier, Hofmann, Brodie and Hummers. Many variations of these methods exist, with improvements constantly being explored to achieve better results and cheaper processes. The effectiveness of an oxidation process is often evaluated by the carbon/oxygen ratios of the graphene oxide.

Graphene oxide uses

Graphene Oxide films can be deposited on essentially any substrate, and later converted into a conductor. This is why GO is especially fit for use in the production of transparent conductive films, like the ones used for flexible electronics, solar cells, chemical sensors and more. GO is even studied as a tin-oxide (ITO) replacement in batteries and touch screens.



Graphene Oxide has a high surface area, and so it can be fit for use as electrode material for batteries, capacitors and solar cells. 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. 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.

Graphene oxide is fluorescent, which makes it especially appropriate for various medical applications. bio-sensing and disease detection, drug-carriers and antibacterial materials are just some of the possibilities GO holds for the biomedical field.

Buy Graphene Oxide

Graphene oxide is relatively affordable and easy to find, with many companies that sell it. It does, however, get confusing since different companies offer products that vary in quality, price, form and more - making the choice of a specific product challenging. If you are interested in buying GO, contact Graphene-Info for advisement on the right GO for your exact needs!

Iodine-doped graphene oxide could be an efficient electrocatalyst for fuel cells

Researchers from the National Institute for Cryogenics and Isotopic Technologies ICSI-Rm in Romania have applied microwave processes to iodine doping and reduction of graphene oxide, to produce functionalized fuel cell organic reduction reaction electrocatalysts. The team chose to utilize microwave-assisted processes because of their many benefits, like reduced energy, time, and cost demands.

The process developed by the team relies on a faster, simpler, more economical, and efficient protocol under atmospheric pressure conditions. Under mild conditions, the microwave-assisted process highlighted in the research synthesizes a canvas-like iodine/reduced graphene oxide structure from graphene oxide. Thus, a low-cost, efficient alternative to platinum-based catalysts has been developed.

Researchers create GO-based system for purifying river water

Researchers from India's Haldia Institute of Technology have created a gravity filter using graphene oxide (GO), meant for purifying river water. Using alternative water resources like river water can help address the rising shortage of freshwater resources worldwide. Therefore, the deployment of cost-effective water filtration technologies is imperative for the desalination of river water and purification of polluted water.

Filtration using a gravity filter is a highly popular method for water purification. A gravity filter is a type of pressure filter wherein water passes through the filtering component on the influent side at atmospheric pressure and the whole system is driven by the force of gravity instead of electricity. A major benefit of gravity filters is that they are free from moving components, therefore require less filter maintenance. Another significant advantage of using a gravity-based water filtration system is that the system does not need a power supply. The main drawback, on the other hand, is the low output of purified water. The limitations of filtering technology imply that no one filtration material can remove all pollutants present in water.

Researchers use green chemistry approach to synthesize graphene oxide/silver nanocomposites

Researchers from Pakistan have reported a green approach to the synthesis of graphene oxide/silver nanoparticle nanocomposite.

Metallic nanoparticles (NPs) have various benefits in the field of electrochemistry. Because of their small size, nanoparticles may enhance the contact area of the electrode in use. Furthermore, metallic nanoparticles may boost the rate of mass transfer and provide quick electron transference, increasing the sensitivities of the used electrodes. Silver nanoparticles (AgNPs) are relatively low cost and have distinct physical and chemical characteristics that make them helpful in several optical, chemical, and catalytic functions.

Graphene oxide helps use disposable face masks to make better concrete

A Washington State University (WSU) research team recently showed that used single-use masks, of the kind made ubiquitous in the pandemic, can be incorporated into a cement mixture (with the help of graphene oxide) to create stronger, more durable concrete. The team found that the mixture using mask materials was 47% stronger than commonly used cement after a month of curing.

Disposable masks could be used to make more durable concrete image

These waste masks actually could be a valuable commodity if you process them properly, said Xianming Shi, professor and interim chair of the Department of Civil and Environmental Engineering and the corresponding author on the paper.
