Influence of Phenylsilane on the Textural, Structural, and Electrochemical Properties of Activated Carbon Nanofiber Composites

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...

Summary: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.
