报道了以廉价、环保、可再生的木材废弃物为原料，首次制备出木材衍生的氮掺杂多孔碳-聚苯胺（NKWC-PANI）复合材料，用于超级电容器电极材料。利用木质氮掺杂多孔炭（NKWC）的高电化学活性以及NKWC与聚苯胺（PANI）粒子之间的协同效应，以NKWC-PANI复合物为活性材料制备的电极比纯NKWC和PANI电极具有更高的比电容。此外，这种新型的NKWC-PANI复合材料也显示出与一些类似的碳-PANI复合材料相当的最大比电容（在2 A g−1时为347 F g−1）和能量密度（在922 W kg−1时为44.4 W h kg− 1）。本研究为制备高性能、低成本的碳基复合电极材料提供了一种有前途的方法。
This paper reports the first wood derived nitrogen-doped porous carbon–polyaniline (NKWC–PANI) composites, prepared with low-cost, environmentally friendly, and renewable wood wastes as raw materials, for supercapacitor electrode materials. Benefiting from high electrochemical activity of wood derived nitrogen-doped porous carbon (NKWC) and the synergetic effect between NKWC and polyaniline (PANI) particles, the electrode with the as-obtained NKWC–PANI composite as active material exhibits significantly higher specific capacitance than the electrodes based on pure NKWC and PANI. Moreover, this novel NKWC–PANI composite also shows comparable maximum specific capacitance (347 F g−1 at 2 A g−1) and energy density (44.4 W h kg−1 at 922 W kg−1) to some similar carbon–PANI composites. This work offers a promising method to produce carbon based composite electrode materials with high performance and low cost.
