Unveiling the supercapacitive behavior of electrospun Cr2CTx/carbon nanofiber membrane

Abstract

A novel electrospinning-based strategy was employed to fabricate Cr₂CT_x/carbon nanofibers using Cr₂CT_x MXene and polyvinyl alcohol (PVA) as precursors. This approach enables the formation of porous, conductive composite MXene layers dispersed in carbon nanofibers. The resulting material exhibited notable supercapacitive performance, delivering 338.8 F g⁻¹ capacitance, 67.7 Wh kg⁻¹ energy, and 1998 W kg⁻¹ power density.
