Structure characterization and oxidation mechanism study of porous biomorphic carbon template derived from basswood
چکیده انگلیسی

A porous biomorphic carbon template (BCT), retained its biological feature, was prepared by carbonized basswood. Microstructure and component of BCT were performed by scanning electron microscope (SEM), energy dispersive spectrometry (EDS) and Raman spectroscopy. Non-isothermal oxidation mechanism of BCT was studied by thermogravimetry analysis (TGA). Experimental results show that BCT has a honeycomb structure and double-peaked porous diameter distribution. It is a typical turbostratic network structure, with increasing carbonization temperature, the ratio of the integrated intensities ID/IG increase, the lateral extension La of the graphene units decrease. The non-isothermal oxidation mechanism of BCT exhibits a self-catalytic characteristic, which is explained by molecular structure schematic model.
