| Abstract: | Carbon hollow spheres were prepared via catalytic pyrolysis with kaolin supported nickel nitrate as catalyst. The hollow carbon spheres were synthesized by the catalytic pyrolysis of C2H2 mixed with N2 at 850 ℃. The characterization of catalyst and hollow carbon spheres were carried out by XRD, TEM, SEM and Raman spectroscopy. The TEM and SEM images suggested that the carbon spheres with diameter about 500 nm were hollow. SEM images and XRD patterns of catalyst suggested some information about the possible formation mechanism of hollow spheres. |
