WebApr 7, 2024 · The Raman spectra of GO, R01 and R10 were examined along with that of MWCNTs, because some of the characteristic graphitic carbon bands are often absent (due to the presence of a large number of defects) in the Raman spectra of GO and rGOs (discussed in detail later), and the absence of such bands has important implications … WebJun 1, 2024 · The Raman spectra of the anodes show contributions from three major components: graphite, carbon black, and fluorescence. The Raman spectra of the cycled anode exhibits two peaks at 1346 and 1582 cm-1, corresponding to the D and G bands, respectively.The D band corresponds to the presence of defects, and the G band …

WebRaman spectroscopy is able to probe disorder in graphene through defect-activated peaks. It is of great interest to link these features to the nature of disorder. Here we present a detailed analysis of the Raman spectra of graphene containing different type of defects. We found that the intensity ratio of the D and D′ peak is maximum (∼13) for sp3-defects, it … WebRaman spectra of vibrational excitations in graphite intercalated with alkali donor atoms have been obtained at room temperature in the backscattering configuration using argon-ion excitation. Stage 1, 2, and 3 cesium donor compounds prepared from highly oriented pyrolytic graphite (HOPG) were studied as were stage 1 and 2 HOPG potassium donor ... WebWe investigate Raman spectra of graphite oxide and functionalized graphene sheets with epoxy and hydroxyl groups and Stone−Wales and 5−8−5 defects by first-principles calculations to interpret our experimental results.
