Abstract

In this study, we presented the synthesis of Fe-graphitic carbon and magnetite Fe3O4-amorphous carbon nanocomposites from catalytic pyrolysis and carbonization of chemically-activated sugarcane bagasse under nitrogen atmosphere. Fe(NO3)3x9H2O was used as an iron precursor for preparing metallic catalyst and K2CO3 as an activating agent. The process was performed using a simple and low-cost chemical vapor deposition method. The obtained products were characterized by TGA, TEM, SEM, XRD, and BET specific surface area. It was observed that, at 800C, Fe(NO3)3x9H2O was decomposed and reduced to Fe3O4, forming magnetite Fe3O4-amorphous carbon nanocomposites. Graphitic carbon was, however, produced at temperatures between 900 and 1000C, at which the iron precursor was reduced into metallic Fe nanoparticles. The BET specific surface area as high as 1159 m2/g could be attained from the Fe/graphitic carbon nanocomposite when carbonized at 1000C..
