The objective of this study involves the synthesis of carbon nanospheres(CNS) from incomplete burning of Iraqi diesel.Also, the synthesized CNS were further treated with hydrochloric acid and sonicated for 1 hour to achieve modified CNS.The results reveal that the produced carbon nanoparticles much smaller than those from the conventional diesel combustion.CNS were characterized using FT-IR spectroscopy (FTIR), scanning electron microscopy(SEM), atomic force microscopy(AFM), X-rays diffraction(XRD), Energy dispersive x-ray microanalysis (EDX), Brunauer-Emmett-Teller (BET) and Thermo gravimetric analysis (TGA). FTIR spectra showed a change is in nature of functional groups and exiting of adsorbed impurities on surfaceof synthesized carbonic materials. The results obtained from of SEM and XRD show a similar structure and morphology of the new materials. Thermal gravimetric analysis (TGA) analyses indicate a gradual weight loss in the temperature range from 0°C to about 700°C.AFM and BET analysis indicted a similar topology and surface area values of both materials. EDS analysis exhibited that carbon was the main product of diesel combustion.
