| 摘 要： | Nickel nanocrystals encapsulated in carbon shells were prepared by the large body knowledge developed for the growth of carbon nanotubes (CNTs), i.e. chemical vapor deposition. The products were characterized by transmission electron microscopy, XRD and FTIR. The results showed that the oxidization of CNT surface made it possible to interreact with nickel ions in solution. Ni-impregnated CNTs transformed into monocrystalline nickel nanoparticles supported on CNTs at 600 ℃ in nitrogen atmosphere. Subsequently, they would be covered with graphene layers during reaction with acetylene at 600 ℃. The formation mechanism has been preliminarily discussed on experimental results.
