Abstract:
A new nitrogen‐doped ordered mesoporous carbon (N‐doped OMC) is synthesized by using an organic–inorganic coassembly method, in which resol is used as the carbon precursor, dicyandiamide as the nitrogen precursor, silicate oligomers as the inorganic precursors, and F127 as the soft template. The N‐doped OMC possesses a surface area as high as 1374 m 2 g −1 and a large pore size of 7.4 nm. As an electrode material for supercapacitors, the obtained carbon exhibits excellent cycling stability and delivers a reversible specific capacitance as high as 308 F g −1 in 1 mol L −1 H 2 SO 4 aqueous electrolyte, of which 58 % of the capacity is due to pseudo‐capacitance. The large specific capacitance is attributed to proper pore size distributions, large surface area, and high nitrogen content.
