|Abstract:||Tubular nanofibers (TNFs) of vanadium pentoxide (V 2O 5) were synthesized by electrospinning technique using a single spinneret for the first time by controlling the properties of the precursor solution. A partially miscible polymeric solution of vanadium oxytrihydroxide [VO(OH) 3] was produced by hydrolysis of vanadyl acetylacetonate in Poly(vinylpyrrolidone) (PVP). The phase-separated polymer solution formed the core of the electrospun fibers whereas the VO(OH) 3 formed the shell; the core PVP has been removed by controlled heat treatment. The TNFs had an inner diameter ̃60 nm and wall thickness ̃±100 nm. The capacitive behavior of the V 2O 5 TNFs was studied using cyclic voltammetry and galvanostatic cycling techniques. The studies showed ideal stable supercapacitive characteristics in the electrospun V 2O 5 TNFs. © Springer Science+Business Media Dordrecht 2012.|
