摘　　要：Nano- sized and well- dispersed Cu- Ni/La2O3 can be obtained by reduction of LaCu0.2Ni0.8O3 with the structure of perovskite. Using Cu- Ni/La2O3 as cata lyst and C2H2 as carbon source, carbon nanotubes with a high yield and narrow di ameter distribution can be obtained in the reaction temperature range of 650～ 7 00℃ . Outer diameter of carbon nanotubes rangs from 9nm to 14nm. TG, Raman and XPS analysis indicate that carbon nanotubes prepared by Cu- Ni/La2O3 are relati vely higher in graphitic degree.Nano-sized and well-dispersed Cu-Ni/La2O3 can be obtained by reduction of LaCu0.2Ni0.8O3 with the structure of perovskite.
