Structural and Magnetic Properties of Fe and Carbon Nanotubes Derived from Coconut Shells

Abstract

Ferric oxide (Fe2O3) was directly reduced to metallic Fe using the carbon source from the coconut shells at temperatures above 1400 degrees C in argon gas atmospheres. X-ray diffraction analysis showed the presence of alpha-, gamma-phases of Fe in addition to the presence of carbon nanotubes (CNTs). By selecting the appropriate ratios of coconut shell powder to Fe2O3, it is demonstrated that pure Fe is produced without any residual ferric oxide. The quantitative analysis of each of the Fe phases and carbon nanotubes was dependent on the temperature and the duration of processing at high temperature. Transmission electron microcopy results showed copious amount of carbon nanotubes in the samples. Magnetic property measurements suggested that, the average magnetic moment is consistent with presence of alpha-phase and the ferromagnetic gamma-phase of Fe. This novel method of producing pure alpha- and gamma-Fe in the presence of carbon nanotubes using coconut shells has potential applications as nanocomposites.
