Cellulose of a major wood component is biosynthesized as nanofibrous structures with a width of about 3 nm. These nanofibers are thus promising raw materials for producing high-performance carbon nanostrucrures. Carbonization of wood celluloses has ever been explored. However, celluloses have a strong tendency to aggregate, so that nanofibrillar morphology of CMFs is lost as the carbonization proceeds.

In our laboratory, aerogels have been developed by using individually dispersed wood cellulose nanofiber (CNF) obtained by TEMPO oxidation. The CNF aerogels have high porosities and large specific surface areas. In a previous study, we prepared carbon materials with the 500°C treatment. It had a CNF-derived nanofibrillar structure and high surface areas. But the 500°C treated product still has same impurities, such as hydrogen and oxygen. In the present study, we report further characterization analysis for 900°C treated product to compare the characteristics with other samples.
