Opis

Opis ogólny

• Chloride free (purified by dialysis)
• Monolayer sheet
• sheet diameter <10 micron

Graphene oxide (GO) is a one atom thick 2D carbon material with excellent thermal, mechanical, and electrical properties due to its unique structural and morphological features. GO can be easily dispersed in aqueous and polar organic solvents to facilitate its practical use. It can be synthesized by modified Hummer’s method. It can be applied in the fields of drug delivery, energy storage, oil-water separation, immobilization catalysis, desalination, and solar cells.

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product belongs to Enabling category of greener alternatives thus aligns with "Design for energy efficency". High concentrated graphene oxide sheets provide the prerequisite viscosity to bind the electrode materials together and enable 3D printing. Using water as a green solvent makes this aqueous ink system feasible for processing and drying safety and low cost. Click here for more information.

Zastosowanie

Because of the presence of oxygen-containing functional groups and acidic nature, GO can serve as both carbocatalyst as well as a supporting scaffold for various catalytically active species. GO can facilitate many organic transformations such as the oxidation of sulfides, olefins, and various hydrocarbons, Friedel–Crafts reaction, Aza–Michael additions, condensation, and ring-opening polymerization.

It can be used as a support for biocatalysis in organic solvents. For example, carboxyl-functionalized graphene oxide can act as a support to immobilize Yarrowia lipolytica lipase. The immobilized enzyme exhibits a high efficiency for the resolution of the racemic compound in the organic solvent.

It can also be used as a hole transport layer in organic photovoltaic cells.
