Synthesis of Mesoporous Carbon Nanofilament and the Application to Electrodes for Electric Double Layer Capacitor

Abstract

Mesoporous carbon nanofilament（CNF）can maintain capacitance in a higher sweep rate area than microporous carbon（activated carbon）. Therefore, synthesized mesoporous CNF is applicable as an electrode material in electric double layer capacitors. For this study, the porous structure and surface area of mesoporous CNF, synthesized by decomposition of C₂H₄ using metallic complex at a mild temperature, were controlled using a catalyst. Results show that the capacitance of the mesoporous CNF per unit of specific surface area is higher than that of activated carbon, demonstrating that it is a suitable electrode material that can improve the rate characteristics of electric double layer capacitors.
