Article Preview

This paper deals with photo electrochemical responses of titanium dioxide nanotubes on pure titanium. Photosensitive electrodes (anodes) with the major composition of doped oxides were made using the titanium oxide nanotubes. The responses of the oxide nanotubes with different additives to both ultraviolet (Uv) and visible (Vis) light were illustrated. Research results of the enhance absorption of visible light by adding transition metals or metallic oxides including Co, Ni, Cu, Zn, CoO, CuO, NiO, ZnO into the nanotubes will be shown. Finally, test results of the photo electrochemical fuel cells using diluted glycerol as the fuel under the irradiation of natural light will be presented and the open circuit voltage values will be given. The photo electrochemical test results show that the doped titanium oxide nanotubes show the n-type behavior. The photo anodes can absorb both ultraviolet and visible light. But the response to the ultraviolet light is five to ten times stronger.
