AB  - Juncus is a perennial herb aquatic plant found worldwide, with high reproductive 
      ability in warm regions. It has three-dimensional hierarchical porous triangular 
      networks structures composited of tubular fibers. Here, juncus derived 
      nitrogen-doped porous carbon (NDPC) was prepared by mixing juncus and ZnCl(2) 
      through one-step pyrolysis and activation which is a low-cost, simple, and 
      environmentally friendly method. The NDPC had hierarchical porous structures and 
      a high specific surface area and was applied for supercapacitor and oxygen 
      reduction reaction (ORR). The resulted NDPC-3-800 was prepared by mixing juncus 
      with ZnCl(2) at a mass ratio of 1:3 and then carbonized at 800 degrees C, it was used as 
      electrode material of a supercapacitor. The supercapacitor exhibited excellent 
      specific capacitance of 290.5 F g(-1) and 175.0 F g(-1) in alkaline electrolyte 
      at the current densities of 0.5 A g(-1) and 50 A g(-1), respectively. The 
      supercapacitor showed good cycle stability, and the capacitance was maintained at 
      94.5% after 10,000 cycles. The NDPC-5-800 was prepared by mixing juncus with 
      ZnCl(2) at a mass ratio of 1:5 and then carbonized at 800 degrees C. It exhibited 
      outstanding ORR catalytic activity and stability attributing to their high 
      specific surface area and abundant actives sites. The juncus can derive various 
      materials for application in different fields.
