In situ nitrogen‐doped hierarchical porous carbon was synthesized by using waste protein‐rich pig nails as precursors in a facile KOH activation method. The microstructure and electrochemical characteristics of the materials were investigated by tuning the amount of KOH. When the weight ratio of KOH to pig nails is 1 : 1, the obtained nitrogen‐doped hierarchical porous carbon (NHPC‐1) exhibits the largest specific surface area (2569 m2 g−1) with interconnected porous network structure, which are beneficial to ion/electron storage and transfer. In addition, abundant nitrogen of 2.8 at % in the NHPC‐1 also contributes to the high electrochemical activity of the supercapacitor during the charging/discharging process. As a result, the NHPC‐1 electrode in the supercapacitor exhibits a high specific capacitance of 231 F g−1 at 1 A g−1 and superior retention of 98 % after 5000 cycles at 1 A g−1 in 6 M KOH electrolyte. Additionally, the assembled symmetric device based on NHPC‐1 exhibits a high energy density of 7 Wh kg−1 at a power density of 500 W kg−1. Our study suggests that waste pig nails can act as low‐cost and renewable carbon precursors for high performance supercapacitor.

Two‐Dimensional Porous Carbon: Synthesis and Ion‐Transport Properties

Their chemical stability, high specific surface area, and electric conductivity enable porous carbon materials to be the most commonly used electrode materials for electrochemical capacitors (also known as supercapacitors). To further increase the energy and power density, engineering of the pore structures with a higher electrochemical accessible surface area, faster ion-transport path and a more-robust interface with the electrolyte is widely investigated. Compared with traditional porous carbons, two-dimensional (2D) porous carbon sheets with an interlinked hierarchical porous structure are a good candidate for supercapacitors due to their advantages in high aspect ratio for electrode packing and electron transport, hierarchical pore structures for ion transport, and short ion-transport length. Recent progress on the synthesis of 2D porous carbons is reported here, along with the improved electrochemical behavior due to enhanced ion transport. Challenges for the controlled preparation of 2D porous carbons with desired properties are also discussed; these require precise tuning of the hierarchical structure and a clarification of the formation mechanisms.
