Electrochemical capacitors using nitrogen-doped vertically aligned multi-walled carbon nanotube electrodes prepared by defluorination

Nitrogen-doped vertically aligned multi-walled carbon nanotubes (N-VAMWCNTs) were prepared by reacting fluorinated VAMWCNTs with ammonia gas at temperatures of 300–600 °C. The N-VAMWCNTs were characterized using scanning electron microscopy, high-resolution transmission electron microscopy, X-ray ph...
