Abstract

Taking peanut shell as raw material, porous carbon which retained biological anatomical features was prepared by temperature-control carbonizing. Composition, morphology, non-isothermal oxidation weight loss curves of porous carbon were studied by SEM, XRD, etc. The results show that the porous carbon had comby pore and the pore diameter were about 10 μm, and different pores were connected by many transverse ribbons. The porous carbon was a typical amorphous state graphic carbon, with increase of carbonization temperature, the (002) peak strength increased, the interplanar spacing increased and the structure slowly evolved toward ideal graphite. The non-isothermal oxidation rate of porous carbon firstly increased and then decreased for the number of activated carbon atom in alkene layer structure changed with oxidation reaction going.
