Reduced Graphene Oxide (1 Gram)


Reduced Graphene Oxide

Reduced Graphene Oxide (rGO) is obtained by reducing Graphene Oxide (GO). It can be done chemically, thermally or via irradiation (UV or IR) to get a powder form.

The great electrical conductivity of this product is an important feature in some research projects.

Frequently Asked Questions

A: rGO is obtained afer a chemical reduction of GO. As a consequence of this reduction part of the sp2 hybridization is recovered and also its conductivity. In the reduction process also part of the functional groups are lost, making rGO hydrophobic. In order to dispersed it in water surfactants have to be added. Also rGO can be dispersed in low concentrations in NMP or DMF.

A: In the rGO most of the functional groups have been reduced. Although there have been several research works about it there is still a lack of information about the structure of both GO and rGO. As in can be observed in XPS data, the C-C bonding quantity increases considerably whereas the C-O bonding decreases. At the same time, a reduction in the carbonyl groups is observed. Unfortunately there is no quantitative data about the functional groups present in the rGO, some carboxyl, epoxy and hydroxyl groups remains can be present.
