Reduced Graphene Oxide-NH

FTIR Spectroscopy: Attenuated Total Reflectance (ATR)

Assignment (cm-1): For rGO-NH 1550 (N–H bending)‚ 1433 (C-N stretching).

Scanning Electron Microscopy

XRD

XRD pattern of GO‚ rGO and rGO-NH.

XPS

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

Elemental analysis

Zeta-potential

Zeta-potential versus pH curve for rGO-NH.

• Amount of NH groups

In order to estimate the amount of NH groups in rGO-NH a reaction with 4-bromobenzyl chloride was performed and the Br amount was quantified by X-ray fluorescence spectroscopy. The value obtained corresponds to 0.13 mmol/g.

• Conductivity

Conductivity of pressed pellets of rGO-NH is 70.75 S/m.
