Abstract
A biomorphic carbon template (BCT) was prepared by carbonizing pine wood under Ar atmosphere. Microstructure and component of BCT were performed by scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS) and X-ray diffraction (XRD). The pyrolytic behavior of pine wood converse to carbon template and non-isothermal oxidation properties of BCT were studied by thermogravimetric analysis (TGA). Experimental results show that BCT has a topologically uniform interconnected porous network microstructure, and is typical non-graphitizable carbon. With increasing carbonization temperature, the (0 0 2) peak becomes stronger, the interplanar spacing decrease, the structure of BCT slowly evolved toward that of ideal graphite. The oxidation reaction of BCT begins at 406.5 °C, and the reaction rate reaches maximum when the residual weight is 36.9%. The oxidation mechanism is one-dimensional diffusion, the kinetic parameters are: lg A (min −1) = 10.367 and E α (kJ mol −1) = 164.17.
