Abstract

Southern yellow pine (Pinus taeda) wood char powder was thermally treated at 1,000°:C in the presence of a 25-nm-size Fe nanoparticle catalyst. The thermally treated carbon materials were analyzed by Raman spectroscopy and high-resolution transmission electron microscopy. Well-aligned graphitic carbon structures with 15 to 17 layers on average were observed. These graphitic carbon structures were similar to those of graphite with an average interplanar distance of 0.34 nm. The Raman spectra results showed that the full-width half-maximum values of Raman G and D bands, and the peak intensity ratio, I_D"/I_G, of thermally treated pine char after an acid purification treatment were 69 cm^-1, 126 cm^-1, and 0.16, respectively.
