Abstract
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° C., and the catalyst is activated by exposure to a reducing atmosphere at a temperature greater than about 900° C.
