Received Date: 8 January 2003

Carbon nanotubes (CNTs) were prepared by decomposition of C₂H₂ over newly developed LaCu_0.2Ni_0.8O_x in the temperature range from 600 to 850℃. The effect of the reaction temperature on the yield of CNTs was investigated in detail. At 680℃, the yield of CNTs reaches 17 g/g.catal. or so. The morphology of CNTs was examined by TEM. The diameter of CNTs rangs from 9 nm to 14 nm.
