In this study, electrospun TiO2/PVP nanofibers on glass substrate were prepared and by heat treatment at 500 °C for 3 h, TiO2 nanofibers were obtained. Morphology and composition of the obtained nanofibers was analyzed by SEM and EDX techniques and results were correlated with the electrospinning process parameters. Upon heat treatment due to loss of organic phase, TiO2 fibers showed shrinkage and their average diameters that electrospun under applied voltages of 10 and 15 kV have been changed from 270 nm to 90 nm and 160 nm to 70 nm, respectively
