For that, titanium dioxide nanotubes (TNTs) were synthesized with uniform size distribution through the hydrothermal method. Also, individual zinc oxide nanobars (ZNBs) without growing substrate and with uniform size distribution were obtained by same method and by wet chemical reaction. These nanostructures were characterized using Electron Diffraction (ED), Scanning Electron Microscopy (SEM) and Nanostructure Metal oxide Nanotubes Nanobars
