| Abstract: 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 catalyst and C2H2 as carbon source, carbon nanotubes with a high yield and narrow diameter distribution can be obtained in the reaction temperature range of 650～700℃. 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 relatively higher in graphitic degree. |
