N,S co-doped porous carbons show appreciable prospects for various application in energy storage devices like Li-ion batteries and ultracapacitors due to its excellent surface wettability large electrical conductivity, better surface area, cost effectiveness and enormous pseudocapacitance. Nevertheless, several synthesis procedures required the tedious, hard/soft templates assisted multiple-step method and with the assistance of or the massive use of chemical reagents, and exogenic sources of nitrogen, that make them very difficult to realize the production and application of industries. In this work, a prospective hierarchical N,S co-doped porous carbons synthesized by a sustainable method through one step carbonization and subsequent activation process by utilizing renewable Artocarpus heterophyllus wood as the primary source material with no templates and additional nitrogen source. The prepared Artocarpus heterophyllus wood derived porous carbons possess a huge specific surface area of 1094 m² g⁻¹ hierarchically ordered porous framework, uniform and nitrogen rich incorporation (6.9 at%). Utilizing these advanced features, a novel Artocarpus heterophyllus wood derived porous carbon-based electrode material exhibited a high specific capacitance of 1097 Fg⁻¹ in 6 M KOH electrolyte with excellent cyclic stability. Hence, a prospective electrode material for supercapacitor applications was successfully developed by a simple synthesis route with naturally available renewable resource Artocarpus heterophyllus wood.

N、S 共掺杂和硼掺杂 Artocarpus heterophyllus 木材衍生的活性炭在超级电容器中的应用


N，S 共掺杂多孔碳因其优异的表面润湿性、较大的导电性、更好的表面积、成本效益和巨大的赝电容，在锂离子电池和超级电容器等储能器件中的各种应用显示出可观的前景。然而，一些合成程序需要繁琐的硬/软模板辅助多步骤方法，并协助或大量使用化学试剂和外生氮源，这使得它们很难实现工业的生产和应用。在这项工作中，利用可再生的 Artocarpus heterophyllus 木材作为主要来源材料，通过一步碳化和随后的活化过程，通过可持续方法合成了一种前瞻性分层 N，S 共掺杂多孔碳，无需模板和额外的氮源。制备的 Artocarpus heterophyllus 木材衍生的多孔碳具有 1094 m ² g ⁻¹ 的巨大比表面积，分层有序的多孔框架，均匀且富含氮的掺入 （6.9 at%）。利用这些先进特性，一种新型 Artocarpus heterophyllus 木材衍生的多孔碳基电极材料在 6 M KOH 电解质中表现出 1097 Fg ⁻¹ 的高比电容，具有优异的循环稳定性。因此，通过使用天然可再生资源 Artocarpus heterophyllus 木材的简单合成路线，成功开发了一种用于超级电容器应用的有前景的电极材料。
