Graphene has been studied for various applications due to its excellent properties. Graphene film fabrication from solutions of graphene oxide (GO) have attracted considerable attention because these procedures are suitable for mass production. GO, howev
Self-assembly of graphene oxide (GO) and Au nanoparticles (AuNPs) was covalently modified by ionic liquid (IL) containing amino groups to prepare the ternary nanocomposite of IL-GO-AuNPs. UV, IR spectra, X-ray power diffraction and scanning electron microscope confirmed the successful hybridization...
During the experiment, the fabricated graphene device is used to sense different pH values in the surrounding liquid environment. The results show that the conductance of the graphene increases quadratically with the increasing pH values, which makes the device a high-sensitivity pH sensor. In the...
Although there remain many obstacles for graphene and its derivatives (e.g., graphene oxide, functionalized graphene) for real membrane applications, graphene will continue to make rapid progress in membrane applications, particularly, such as gas and liquid separations. This article will cover ...
The graphite oxide interlayer separation is 6.35 Å. However, in liquid, it increases from 6.35 to 11.6 Å. The characteristics of graphene oxide can be altered by functionalization on the basis of the specific application. The existence of both the electron-rich oxygen species and the ...
