Nanometer (nm) scale 1D zinc oxide (ZnO) nanofibers were fabricated through sol-gel processing and electrospinning of Polyvinyl alcohal (PVA) and zinc acetate precursors. The structure and morphologies of the zinc acetate/PVA precursor and ZnO nanofibers were studied by fourier transform infrared (FTIR), X-ray diffraction (XRD), thermogravimetric analysis (TGA) and field emission scanning electron microscopy (FE-SEM). Bead free smooth nanofibers with increased average diameters (278 nm (5 wt.%) and 423 nm (15 wt.%)) were obtained as the content of zinc acetate precursor was increased. The calcination temperature of 480 degrees C was determined from TGA. FTIR, XRD and TGA studies carried out after calcinations, confirmed the formation of ZnO nanofibers by the appearance of a band at 472 cm(-1), characteristic ZnO pattern (i.e. peaks at similar to 31.820, 34.331, 36.496, 47.569 and 57.168 2 theta degree) and no weight loss after 480 degrees C, respectively. The burning of polymer has also been confirmed by a significant decrease in average diameter (124 nm (5 wt.%) and 197 nm (15 wt.%)) of the ZnO nanofibers. Electrospinning has been found to be a simple and cost effective technique for the synthesis of ID ZnO nanofibers mat for potential applications in the renewable energy devices.
