Boron-nitrogen functional groups on porous nanocarbon fibers for electrochemi…

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…
