Globally, rice consumption is increasing and consequently large quantities of rice husk are generated. These husks are an agricultural waste and are usually disposed of by incineration, which creates air pollution in the form of ash and fine silica particles, which are toxic. Additionally, Silicon Carbide (SiC) nanowires and nanorods have attracted much interest because of their potentially novel physical properties resulting from quantum confinement. In this paper, we will demonstrate that large quantities of the nanostructures of β-SiC can be obtained from the agricultural waste of rice husks by controlled conditions of temperature and surrounding atmosphere. Using x-ray diffraction, SEM, TEM, and Raman Spectroscopy, we will show the simultaneous formation of carbon nanotubes and nanorod/nanowires of β-SiC from the pyrolysis of rice husks. The separation of these nanostructures from the extraneous by-products will be discussed and the use of graphite and nano-particles to improve the yield of nano-structures.
