Abstract

Ordered bi-phase TiO₂ nanowire arrays were simply obtained by heat treating TiO₂ nanotube arrays prepared by a two-step anodization method. The nanowire arrays are composed of anatase and rutile phases with uniform diameters around 50 nm. The photocatalysis activities of TiO₂ nanowire arrays were characterized by quantifying the degradation of methyl orange solution. And the results indicated that the bi-phase nanowire arrays, especially obtained at 700 °C, showed much higher activity than that of P25 film or anatase TiO₂ nanotube array.
