Azide-assisted hydrothermal synthesis of N-doped active carbon with high conductivity for supercapacitor

In our investigation, the sodium azide–assisted hydrothermal method was employed to prepare the N-doped active carbon (NAC). The TEM image shows that the NAC demonstrated lattice fringes (0.398 nm) representing the graphitized area. The NAC has high adsorption surface (1903 m 2  g −1 ). A variety of...
