To prove that an experimental sample is graphite oxide (GO), graphene oxide (GO), or carbon nanotubes (CNTs) using only Raman spectroscopy and X-ray diffraction (XRD), you can look for the following key features: Raman spectra should show the characteristic D and G bands, with additional defect-induced bands like D' and G' for GO and CNTs. The XRD pattern of GO and rGO will exhibit a broad peak around 10-20° 2θ, while CNTs will show sharp peaks around 26° 2θ. Careful sample preparation and accounting for fluorescence background in Raman measurements are also important. By comparing the observed Raman and XRD data to the known characteristics of these carbon materials, you can confidently identify the nature of your experimental sample.
To identify graphite oxide, graphene oxide, or carbon nanotubes using Raman spectroscopy and X-ray diffraction (XRD), look for key features in the Raman spectra: the D band around 1350 cm-1, the G band around 1580 cm-1, and the 2D band around 2700 cm-1, along with the intensity ratio ID/IG. In XRD, graphite oxide and graphene oxide show peaks around 2θ = 10-12°, while carbon nanotubes exhibit peaks at 2θ = 6° for single-walled and 25-26° for multi-walled nanotubes.
