Black Liquor and Wood Char-Derived Nitrogen-Doped Carbon Materials for Supercapacitors
Herein, we present a synthesis route for high-efficiency nitrogen-doped carbon materials using kraft pulping residue, black liquor, and wood charcoal as carbon sources. The synthesized nitrogen-doped carbon materials, based on black liquor and its mixture with wood charcoal, exhibited high specific...

| description | Herein, we present a synthesis route for high-efficiency nitrogen-doped carbon materials using kraft pulping residue, black liquor, and wood charcoal as carbon sources. The synthesized nitrogen-doped carbon materials, based on black liquor and its mixture with wood charcoal, exhibited high specific surface areas (SSAs) of 2481 and 2690 m<sup>2</sup> g<sup>−1</sup>, respectively, as well as a high volume of mesopores with an average size of 2.9–4.6 nm. The nitrogen content was approximately 3–4 at% in the synthesized nitrogen-doped carbon materials. A specific capacitance of approximately 81–142 F g<sup>−1</sup> was achieved in a 1 M Na<sub>2</sub>SO<sub>4</sub> aqueous solution at a current density of 0.2 A g<sup>−1</sup>. In addition, the specific capacitance retention was 99% after 1000 cycles, indicating good electrochemical stability. |
