Titanium oxide nanotubes were fabricated by anodic oxidation of a pure titanium sheet in 1.5 M H2SO4, 0.3 M H3PO4 and 0.3 M H2O2 mixture solution. The morphology of Titanium oxide nanotubes surface were investigated by scanning electron microscope (SEM). These tubes are well aligned and organized into high-density uniform arrays. While the tops of the tubes are open, the bottoms of the tubes are closed, forming a barrier layer structure similar to that of porous alumina. The average tube diameter, ranging in size from 40 to 70 nm.
