Nitrogen-doped hierarchical porous hard carbon (NPC) that are capable of high N content, high specific surface area and high chemical stability has the potential to be a promising electrode material for energy storage application. Here we report a N-doped hierarchical porous hard carbon via a facile Ti-peroxy initiated in-situ polymerization ofp-phenylenediamine. Ti-peroxy can also serve as a hard template to manipulate the formation of hierarchical porous. This nitrogen-doped hierarchical porous hard carbon has advantages of high N-content (7.2 at. %) and high surface area (1515 m2g−1), displaying a specific capacitance of 360 F g−1and an extraordinary cycling stability above 98% after 30,000 cycles.
