Reduced Graphene Oxide and Applications

Graphene oxide (GO) is a type of graphene that contains oxygen functional groups and has some interesting properties different than those of graphene. By reducing graphene oxide, reduced graphene oxide is obtained which is abbreviated to rGO. In this process, the functional groups of graphene are removed but it still contains residual oxygen, hetereatoms and structural defects which decrease its quality. Having less-quality compared to pristine graphene, rGO is still an outstanding material for various applications since it resembles an attractive cost and manufacturing processes compared to the pristine graphene. Especially, it is preferred in applications that call for a large amount of material.
Depending on the method of preparation of reduced graphene oxide, properties and morphology of the rGO can vary. Some preparation methods of reduced graphene oxide include:
  • treating graphene oxide with hydrazine hydrate at 100°C for 24 hours
  • exposure to hydrogen plasma for several seconds
  • exposure to powerful pulsed light from xenon flashtubes
  • heating the graphene oxide with urea as an expansion-reduction agent
  • direct heating of graphene oxide in a furnace to very high temperatures
Applications of Reduced Graphene Oxide (rGO)
Electronics: rGO shows a great potential in electronics applications. It is used as a field effect transistor that has been used in chemical sensors and biosensors. In biosensors, detect hormonal catecholamine molecules, avidin and DNA. rGO is also used in light emitting diodes (LEDs) and solar cell devices. For these applications, having transparent electrode is important and rGO is a convenient for these devices.
Energy Storage: Nanocomposites of rGO is used for lithium-ion batteries, extensively. In these batteries, nanoparticles of insulating metal oxide are absorbed onto rGO which enhances the performance of these materials in lithium-ion batteries.
It is also used in many composite materials and printable graphene electronics.
Overall, rGO is a suitable material for many applications although it looks like less impressive when it is compared to graphene.

Cadmium Sulfide Nanopowder and Its Applications

Cadmium sulfide is the inorganic compound with the formula CdS. Cadmium sulfide is a yellow solid. It occurs in nature with two different crystal structures as the rare minerals greenockite and hawleyite. As a compound that is easy to isolate and purify, cadmium sulfide the principal source of cadmium for all commercial applications. Its vivid yellow color led to its adoption as a pigment for the yellow paint "cadmium yellow" in the 18th century. Cadmium Sulfide Nano Powder, CdS (99.9+%, 20 nm)  shows unique physical, chemical and structural properties from the bulk. The melting point, electronic absorption spectra, band gap energy crystal structure, and other properties of cadmium sulfide nanoparticles are affected by size. Thus, cadmium sulfide on the whole is an attractive system for practicing synthetic chemistry for nanocrystals and for understanding the chemistry, growth history of nanomaterials and also for various technical applications. Colloidal dispersions of ...

Carbon Nanotubes Doped with Graphene Nanopowder and Applications

Carbon nanotubes and graphene are different forms of carbon atom based materials. They have different properties and can be used in various applications. But what happens if we use them as a hybrid structure? The excellent mechanical, physical, and chemical properties of low-dimensional carbon materials like graphene and carbon nanotube have enabled them as promising building blocks for three-dimensional nanoarchitectures. In this regard, extensive interests have been attracted to synthesize graphene and carbon nanotube hybrid structures. Earlier works suggested that  Carbon Nanotubes Doped with Graphene Nanopowder (52 wt% Graphene )  is a promising solution for quick energy dissipation, which could enhance interface thermal conductivity of the ‘building blocks’ for future nanoscale mechanical and electrical devices. In the electricity perspective, it is found that ‘CNT pillared-graphene’ system would extend the excellent electrical conductivity of graphene and nanotube to ...
