Nitrogen-doped porous carbon simply prepared by pyrolyzing a nitrogen-containing organic salt for supercapacitors

---

Abstract.
Nitrogen-doped porous carbons are very simply prepared by direct pyrolysis of a nitrogen-containing
organic salt, the tetrasodium salt of ethylenediamine tetraacetic acid for example, at 600–900 ◦C in an
inert atmosphere without activation. The porosity and surface chemistry of the carbon depend strongly
on the pyrolysis temperature. The surface area and pore volume increase with the pyrolysis temperature,
and vary from 408 to 1171 m2 g−1 and 0.209 to 0.709 cm3 g−1, respectively. While the nitrogen content
decreases from 8.59 at% for pyrolysis at 600 ◦C to 1.02 at% at 900 ◦C. The unique microstructure and nitrogen
functionalities enable the carbon to exhibit a capacitance of 245 F g−1 in a 6 mol L−1 KOH aqueous
electrolytes, which is attributed to the contributions of double layer capacitance and pseudo-capacitance,
with an excellent rate capability (188 F g−1 remained at 20 A g−1) and cycle durability.
