WebMoreover, a graphitic G-band at ∼1599 cm −1 corresponded to the graphitic domains in the framework. The Raman spectrum confirmed that the D-bands at 1380 cm −1 developed from the disorder in sp 2 hybridized carbon, and the G-bands at 1599 cm −1 corresponded to graphitic structures. The D band position in the Raman spectrum of the GQDs ... WebFeb 13, 2024 · The graphitic domains are enriched with delocalized π electrons, which have higher reactivity than the oxidized area and can participate and catalyze the reaction under the confinement condition. Zhu et al. have also demonstrated that graphite domains on GO can selectively bind to aromatic compounds through π-π stacking and π-H …
