Binding energies (eV) and deconvoluted peaks (%) for C1s‚ O1s and N1s core levels

Elemental Analysis

The number of free amino groups measured with a quantitative Kaiser test: 0.1 mmol NH2/g.

Amount of NH2 groups:

In order to estimate the amount of NH2 groups in rGO-NH2 a reaction with tetrabromophthalic anhydride performed and the Br amount was quantified by X-ray fluorescence spectroscopy and by the Schöniger flask test. The value obtained corresponds to 0.23 mmol/g and 0.21 mmol/g respectively.
