Abstract

A simple method to synthesize nitrogen-doped activated carbon by using simple thermal treatment of a mixture of activated carbon and melamine was introduced. About 6 at% of nitrogen were successfully doped into the activated carbon, and it affected the electrochemical properties dramatically. The nitrogen-containing groups could be intercalated and diffused into the pores of the activated carbon and blocked them, resulting in decreased surface area and volume. However, the cyclic voltammetric current density was significantly increased in the nitrogen-doped activated carbon compared to the bare activated carbon, demonstrating the positive effect of nitrogen doping on the performance of supercapacitors and energy storage devices.
