Amorphous-crystalline TiO2/carbon nanofibers composite electrode by one-step electrospinning for symmetric supercapacitor

The synthesized amorphous and tetragonal rutile TiO2 inside CNFs act as rich electrons collective, meanwhile, the crystal-amorphous TiO2 has great wetting ability because of high sorption of H2O, OH−, thus the “synapse-like” nanoparticles provide more effective contact area and introduce pseudo-capacitance as compared to pristine electrospun CNFs.
