Elaboration and high resolution TEM characterization of SnO2 nanowires

► SnO2 nanowires were synthesized by electrodeposition and oxidation in AAO template. ► The growth mechanism of Sn nanowires is a brick-stacked wirelike growth. ► SEM and TEM studies have shown the uniform structures of these nanowires. ► Tetragonal SnO2 phase has been identified by XRD and confirmed by HRTEM. ► HRTEM image shows polycrystalline nanowire with grains size equal to 5 nm.
