Raman spectroscopic investigations of activated carbon materials
2002年7月15日 · We have found the peak intensity ratio of G2 to G1, the I (G1)/I (G2) ratio, as a useful parameter expressing the relative content of the disorder part to the order part in the activated carbons, revealing the structural changes induced by anneal or activations.
Raman spectroscopy of carbon materials and their
2023年6月1日 · Raman spectroscopy has now become accepted to be one of the most powerful techniques for characterising structure–property relations in carbon materials, including 0D fullerenes, 1D CNTs and CFs, 2D graphene and its derivatives, 3D graphite and diamond.
A concise review of the Raman spectra of carbon allotropes
2022年8月1日 · The Raman spectra of many newly-synthesised, mixed-hybridisation, carbon allotropes are reviewed for the first time, e.g. carbyne, carbyne stabilised in carbon nanotubes, graphyne, graphdiyne, ultrananocrystalline diamond, tetrahedral amorphous carbon, and amorphous/paracrystalline diamond.
