Title: METHOD FOR LOW TEMPERATURE SYNTHESIS OF SINGLE WALL CARBON NANOTUBES
Abstract:
The present invention is directed towards a method of producing single wall carbon nanotubes which comprises providing a catalyst comprising an alumina support and a component selected from the group consisting of reduced Fe, reduced Fe/Mo, Fe oxide, and Fe/Mo oxide, and growing, in an inert atmosphere, single wall carbon nanotubes by passing a gas comprising methane over the catalyst at a temperature and for a time sufficient to grow single wall carbon nanotubes. The invention is also directed towards a single wall carbon nanotube produced by such a method. The invention is also directed towards a catalyst for producing SWNTs, wherein the catalyst comprises an alumina support and a component selected from the group consisting of reduced Fe, reduced Fe/Mo, Fe oxide, and Fe/Mo oxide.
