摘要：

Four different high-valent transition metal oxides (VO2, Nb2O5, Ta2O5 and WO3) are investigated for the catalytic effect on the carbonization of polyvinyl alcohol. X-ray diffraction, infrared carbon-sulfur analyzer, transmission electron microscopy and Raman spectroscopy are employed to study the compositions and structures of the residual carbon and resulted metal oxides. The roles of different high-valent transition metal oxides and specific surface areas are discussed in the high temperature carbon thermal reduction process for the residue and form of carbon. It is found that VO2 as the most effective catalyst and polyvinyl alcohol as the carbon source leads to the highest amount of carbon residue (21.34wt%) and the lowest ratio of sp(3) to sp(2) (0.18).
