摘要： 在高岭土负载的镍催化剂上,于850 ℃催化裂解乙炔制备了直径约500 nm 的空心碳球.用XRD、TEM、SEM和显微激光Raman光谱对所得的碳球及催化剂进行了表征,并初步探讨了反应机理.

关键词: 空心碳球, 镍, 高岭土, 乙炔, TEM, SEM, XRD

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.

Key words: Hollow carbon
