The surface of carbon nano-particles (CNPs) was modified by the functionalization of aromatic amine type and of amide-amine type. Transmission electron microscopy (TEM) was used for investigation of surface morphology of pristine and modified nano-particles. The chemical composition of CNPs was studied by X-ray photoelectron spectroscopy (XPS) and Fourier transform infrared spectroscopy (FTIR). The total pore volume, surface area and pore size distribution were also determined by measuring of Brunauer-Emmett-Teller (BET). FTIR and XPS equally confirmed the presence of amino groups linked to the CNPs. It is shown that by the chemical modification the CNPs surface and pores within were grafted with nitrogen functional groups. (C) 2013 Elsevier B.V. All rights reserved.
