Figure 2: Comparison of GOFe and GOMn.
From: An iron-based green approach to 1-h production of single-layer graphene oxide
(a) Raman spectra recorded using 514 nm laser excitation, (b) XRD spectra, (c) ultraviolet–visible spectra recorded in aqueous solution at 0.05 mg ml−1, (d) TGA plots, (e) Fourier transform infrared spectra and (f–h) XPS spectra and its C1s XPS spectra of GOFe and GOMn. 1 and 2 denote GOFe and GOMn, respectively. All of these data show that GOFe and GOMn have similar composition and structures.
