(a) High-resolution C1s and (b) O1s XPS spectra of initial GO reduced by alkaline solution (rGO_NaOH), sodium silicate (rGO_Sil), and sodium silicate with magnesium sulphate (rGO_Sil-Mg). The spectra and their fits are shown after the Shirley background subtraction and vertical offset from the fitting components.
