Boron-nitrogen functional groups on porous nanocarbon fibers for electrochemical supercapacitors

---

Abstract.
Boron- and nitrogen-containing porous carbon nanofibers (BN-CNFs) were prepared through one-step
electrospinning using boric acid (H3BO3) and urea as boron and nitrogen precursors and a subsequent
thermal treatment. The BN-CNFs showed higher capacitance and energy/power density values than the
control sample of CNFs in aqueous electrolyte; the large surface area of 559 m2 g-1 and the NH, COOH,
and [O]BN functional groups facilitated these improvements. The specific capacitance of the supercapacitor
was 180 F g-1 at 1 mA cm-2, and the energy density was 17.2–23.5Wh kg-1 in the power
density range of 400–10,000Wkg-1 in an aqueous electrolyte.
