Copyright 2023 American Chemical Society. (B & C) PM IRRAS spectra of the GO film at the gold surface in 0.1 mol·L-1 NaF/D2O in the 1500 ~ 1800 cm-1 region (B) and 1150 ~ 1500 cm-1 region (C). The potential was cathodically scanned from 0.2 V to -1.0 V. Reprinted with permission from Ref. [92]. Copyright 2023 American Chemical Society. (D) Variation of the intensities of the C=C (red circles) and C=O (blue triangles) bands in GO as a function of the electrode potential in the cathodic scan (from 0.2 V to -1.0 V).
