[22] found that there are four main peaks in the FT-IR spectra of GO, as described detailedly in the following. Firstly, the peak at 1,050 cm−1 arises from epoxide groups (C–O‒C). Secondly, the one centered at 1,680 cm−1 corresponds to the vibrational mode of the ketone groups (‒C=O). Another peak at 1,380 cm−1 is assigned to a C–O vibrational mode.

During optimization, dissociation of epoxide, formation and release of H2O molecules, breaking of carbon-rings on the basal plane, and other structural damages were observed in some of the random GO configurations, especially for those with relatively high coverage rates (R ≥ 30 %). 6a. In the ordered motifs, epoxide and hydroxyl groups distribute closely together, leading to formation of hydrogen bonds and lowering the total energy of the system, consistent with previous theoretical predictions [21–24].
