ZnO is known as a wide band gap (3.37 eV) semiconductor and for its special properties like piezoelectricity and photoconductivity, photoluminescence [1], among others, which can result in innovative solutions in high technology. However, the reduction of ZnO size to nanometric scale such as nanotubes, nanoparticles, nanofibers, nanowires, etc., the possibilities of technological applications increase . Particularly ZnO nanofibers, due to its electric and optic properties, allow to develop solar cells, nano sensors, opto-electronic devices. The electrospinning technique (Fig. 1) allows to produce easily high quality polymer composite and metal oxide nanofibers
