Facile Fabrication of Free-Standing Titanium Dioxide Nanorods Array with Highly Efficient Ultraviolet Light Induced Photocatalytic Activity
In this paper, the fabrication and characterization of free-standing titanium dioxide nanorods array film with pure anatase-phase are presented. Highly oriented TiO2 nanorods array was firstly prepared by hydrothermal method with metal Ti foil, and then the free-standing film can be obtained through selective-dissolution of the metallic Ti substrate by Br2 steam with preserving the original array structure. The crystal structural, morphological, lattice structural and optical information of the free-standing array film were studied. In addition, photo-degradation of crystal voilet in aqueous solution was used as a probe to assess the photo-catalytic activity of the free-standing array film under UV irradiation.
