A biomorphic carbon template (BCT) was developed by carbonizing pine under vacuum. Structural and oxidation properties of BCT were evaluated by scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), and thermogravimetric analysis (TGA). Experimental results show that BCT has a topologically uniform interconnected porous network microstructure, and is typical non-graphitizable carbon containing C = C bonds, C-O-C bonds and a C H structure. The non-isothermal oxidation properties of BCT exhibit a partially self-accelerating characteristic; the oxidation process of BCT is firstly controlled by a chemical reaction, and then controlled by a chemical reaction and gas diffusion together, which is obtained from a Vyazovkin model-free method, and the corresponding activation energy (E) is also calculated.
