Abstract: TiO2 nanotube array thin films were prepared by put Ti substrate into 0.5mol/L NH4HF2+ lmol/L NH4H2PO4 aqueous solution via anodic oxidation method for 2h.The outer voltage used in this work is respectively 5,10,20,30 and 40V.The as anodized TiO2 nanotube thin film is annealed in furnace at 500℃for 2h. The anatase TiO2 nanotube with different structure could be finally obtained.The variations of open circuit ... More
