The present disclosure is directed to a method for producing SWCNT from endothermic carbon-containing feedstock, such as, methane gas, using an activated alumina supported Fe:Mo catalyst. The SWCNT growth temperature is less than about 560&#xb0; C., and the catalyst is activated by exposure to a reducing atmosphere at a temperature greater than about 900&#xb0; C.

Low temperature single-wall carbon nanotube synthesis

An alkali metal-containing catalyst is prepared by providing a catalyst-containing component which contains an alkali metal and another catalyst metal, for example, transition and platinum group metals, and contacting the catalyst-containing component with a binder agent in the presence of a non-aqueous, non-polar component to form a mixture. The mixture is then applied to a suitable catalyst substrate and calcined at the appropriate temperature to produce the alkali metal-containing catalyst. One preferred alkali metal is sodium, and oxides of silicon, aluminum and zirconium may be used as binder agents.
