Carbon nanotubes (CNTs) were prepared by decomposition of C2H2 over newly developed LaCu0.2Ni0.8Ox 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.
