摘要

Structural, optical and photocatalytic properties of various TiO_2 nanostructures prepared by glancing angle deposition (GLAD) and by electrochemical anodic oxidation of Ti were studied. The TiO_2 nanorods were prepared on unheated glass substrates by reactive sputtering of Ti in a mixture of Ar and O_2 gases in a glancing angle deposition (GLAD) regime. The crystal structure of the TiO_2 nanorods was characterized by X-ray diffraction (XRD) and the obtained spectra showed that both anatase and rutile phases are present in the GLAD deposited nanorods with the ratio which corresponds to the ratio of Ar and O_2 in the working gas. In addition, TiO_2 nanostructures were fabricated by electrochemical anodic oxidation of Ti films and Ti nanorods prepared by GLAD in the oxygen free atmosphere at 0.1 Pa of Ar.
