【 摘 要 】

Activated carbon nanofibers (ACNFs) containing oxygen, nitrogen, and silicon are prepared from polyacrylonitrile (PAN) and phenylsilane (PS) by simple electrospinning. The PS introduction into a PAN solution causes a porous structure with functional groups by spontaneous sol‐gel reaction without any catalyst of PS in the physical activation process. PS‐ACNF electrode shows the highest specific capacitance, 200 F/g, and the highest energy density, 25.6–119.19 W h/kg in the range of 400‐10 000 W/kg in a 6 M KOH aqueous solution. Our results suggest that the porosity and functional groups of the supercapacitor electrodes have a strong impact on the enhanced electrochemical properties, resulting from an increased electroactive surface area.
