By electrophoretic deposition of TiO2 colloidal suspensions into the pores of an AAM, ordered TiO2 nanowire arrays can be obtained In a typical procedure, TTIP is dissolved in ethanol at room temperature, and glacial acetic acid mixed with deionized water and ethanol is added under pH = 2-3 with nitric acid. TiO2 nanotubes can also be obtained using the sol-gel method by templating with an AAM and other organic compounds. For example, when an AAM is used as the template, a thin layer of TiO2 sol on the wall of the pores of the AAM is first prepared by sucking TiO2 sol into the pores of the AAM and removing it under vacuum; TiO2 nanowires are obtained after the sol is fully developed and the AAM is removed. The AAM was hydrolyzed by water vapor over a HCl solution for 24 h, air-dried at room temperature, and then calcined in a furnace at 673 K for 2 h and cooled to room temperature with a temperature ramp of 2 ¡ãC/h.
