Carbon nanotubes (CNTs) have been synthesized over Ni-MgO and Ni-Sm-MgO catalysts by decomposition of CH4 at 650 ℃. The addition of Sm into Ni-MgO catalyst not only promotes the catalytic activity and lifetime of the catalyst, but also improves the graphitization and heat stability of carbon nanotub...
