$TiO_2$ nanofibers were fabricated by annealing electrospun $TiO_2$/PVP nanofibers for 3 h at $500^{\circ}C$ in air. Size and uniformity of electrospun $TiO_2$ nanofiber diameters were evaluated via XRD and SEM by varying electric field, PVP concentration, Ti tetraisopropoxide concentration and precursor flow rate. Experimental results revealed that the effect of PVP concentration on size and uniformity of electrospun $TiO_2$ nanofiber diameters was most profound, however, the other effects were relatively small. Uniform fibers with no beads were observed for the electrospun anatase titania nanofibers with a diameter of 170 nm.
