Carbon nanotubes (CNTs) have been a category of the most actively investigated materials both in physics and chemistry sectors in recent years. MgO-supported iron catalysts have been demonstrated to be efficient for single- -walled carbon nanotube (SWCNTs) synthesis. MgO is favored also because it can be removed by a relatively mild acid treatment compared to other support materials. In this work, a Fe-MgO catalyst derived from a mixture of iron-magnesium hydrotalcite-like compound and basic magnesium carbonate : ?????;?????, ,was used in the catalytic growth of SWCNTs from methane. The results showed that high quality SWCNTs with an intensity ratio of D band to G band of less than 0.05 are prepared at 1123 K. The diameters of the SWCNTs are in the range of 0.88-1.79 nm. The catalyst calcined from the precipitation which was rinsed with alcohol shows a higher activity for the growth of SWCNTs than the catalyst rinsed with water
