Ordered bi-phase TiO2nanowire arrays were simply obtained by heat treating TiO2nanotube arrays prepared by a two-step anodization method. The nanowire arrays are composed of anatase and rutile phases with uniform diameters around 50nm. The photocatalysis activities of TiO2nanowire 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 TiO2nanotube array.
