GO and RGO were characterized by XRD, SEM and Raman. According to the peak position and intensity of the D, G and G′ band in Raman spectra, the influence of KMnO4, H2O2 and hydrazine hydrate on the structure of graphene was studied. The results show that the ID/IG value is the ...
3.2 Raman spectra of graphene oxide and carbon fibers Raman spectroscopy is a technique widely used for analyzing carbon- based materials due to its sensitivity to different carbon structure, which produce distinctive Raman peaks for various forms of carbon. Fig. 9.a shows the Raman spectrum of ...

By the virtue of its remarkable physical-chemical prop- erties and molecular structure, graphene opens up a unique platform for SERS studies. It can be as a Raman probe, or as a substrate, or as an additive in SERS22. Similarly, as a typical layered two-dimensional chalcogenide mpfA(og...
Raman spectra of composite aerogels of polytetrafluoroethylene and graphene oxide (reduced grahpene oxide) (PTFE-GO (RGO)) are obtained and described. Five peaks (two Gaussians and three pseudo-Voigt functions) are used to describe spectra in the region of 800-2100 cm(-1). Thermal and ...
Consequently, traditional characterisation techniques, which estimate the quality of the graphene material using the intensity ratio between the D and the G peaks, are unreliable for both GO and rGO. Herein we reanalyse the Raman spectra of graphenes and show that traditional methods rely upon an ...
