Graphene oxide is highly desired for printing electronics, catalysis, energy storage, separation membranes, biomedicine, and composites. However, the present synthesis methods depend on the reactions of graphite with mixed strong oxidants, which suffer from explosion risk, serious environmental pollution, ...
While the production of graphene oxide (GO) and reduced graphene oxide (rGO) have been typically created from synthetic and flake graphite, high purity natural vein graphite has yet to be utilized fully. Therefore, the objective of the present study was to synthesize GO and rGO from high purit...
The Ag NMs were then wrapped with a graphene oxide (GO) shell via static interactions. The GO-wrapped Ag NMs exhibited a further better SERS performance in terms of sensitivity, homogeneity and stability compared with non-wrapped ones, indicating that the heterostructure could be potentially useful...
We report a green and efficient method for chemoselective deoxidization of graphene oxide via the ultraviolet irradiation catalyzed with 2,2,6,6-tetramethyl-4-piperidinol. While the sp(2)-hybridized oxygen functional groups are removed after the reduction, the epoxy and hydroxyl groups are retained...
Here,we report the facile synthesis of graphene oxide/gold nanocomposite,and dye removal ability as an adsorbent was studied.Sodium citrate as a reducing agent was used to reduce Au(III)ions to the formation of gold nanoparticles on the surface of graphene oxide sheets that were prepared by Hum...
Graphene is an advanced carbon functional material with inherent unique properties that make it suitable for a wide range of applications. It can be synthesized through either the top–down approach involving delamination of graphitic materials or the bo
Graphene oxide and functionalized graphene oxide are promising 2D materials that meet the requirement of a sustainable green catalyst due to their extraordinary characteristics like high electrical conductivity, unique electronic structure with zero bandgaps, and high surface-to-volume ratio. This mini-...
graphene and its derivatives have a large surface area, superior electronic and mechanical properties, exceptional charge transport mobility, and very high thermal conductivity, suggesting that they could be used in a variety of applications including solar cells, supercapacitors, sensors, solar cells, ...
