Abstract:
Cellulose-nanofiber carbon which can achieve a large specific surface area, and a method of producing the same are provided. The method for heat treating a cellulose nanofiber for carbonization includes: a freezing step of freezing a solution or gel containing the cellulose nanofiber to obtain a frozen product a drying step of drying the frozen product in a vacuum to obtain a dried product and a carbonizing step of heating and carbonizing the dried product in an atmosphere which does not burn the dried product to obtain the cellulose-nanofiber carbon.
