Description
Summary:Single-walled carbon nanotubes (SWNTs) are successfully grown on magnesite crystal by pyrolysis of methane gas under moderate conditions, demonstrating the possibility of naturally occurring SWNTs. The obtained SWNTs were analyzed by Raman scattering, transmission electron microscope (TEM), and thermogravimetric (TG) measurements. These measurements revealed that high purity SWNTs having diameters of about 1–1.8 nm occur on the surface of natural magnesite sample by the pyrolysis of methane gas at 1073–1173 K. Structural properties and formation mechanism of the obtained SWNTs were discussed.
