Title: SiC/Si{sub 3}N{sub 4} nanotubes from peanut shells

Abstract

Nanotubes and nanoparticles of SiC and Si{sub 3}N{sub 4} were produced from the thermal treatment of peanut shells in argon and nitrogen atmospheres respectively, at temperatures in excess of 1350°C. Using x-ray diffraction, Raman spectroscopy and transmission electron microscopy analysis, the processed samples in argon atmosphere were shown to consist of 2H and 3C polytypes of SiC nanoparticles and nanotubes. Whereas the samples prepared in nitrogen atmosphere consisted of α-phase of Si{sub 3}N{sub 4}. Nanostructures formed by a single direct reaction provide a sustainable synthesis route for nanostructured SiC and Si{sub 3}N{sub 4}, for potential engineering applications due to their exceptional mechanical and electro-optic properties.
