摘要
Well-aligned TiO2 nanowire arrays have been synthesized by anodic oxidative hydrolysis of TiCl3 within a hexagonal close-packed nanochannel alumina on an Au substrate. X-ray diffraction spectrum. Raman scattering spectrum, scanning electron microscopy, and transmission electron microscopy analysis show that the single-crystalline anatase TiO2 nanowires, 15 nm in diam, are uniformly assembled into highly ordered pores of the anodic alumina. Finally, the growth mechanism of the TiO2 nanowires is discussed. The well-aligned TiO2 nanowire arrays will be useful for study of the photoelectrochemical properties of TiO2 nanowires and application in photoelectrochemistry. (C) 2001 The Electrochemical Society.
