Copper and iron oxide films deposited in Titanium Nanotubes

A tubular TiO2 / Ti matrix obtained by the electrochemical anodization method was used as a substrate for the deposit of a single litter of CuO (copper oxide) or CuO doped with 1% Fe by the spin coating method. In the anodizing methods two different times of 40 and 60 minutes were used respectively. In obtaining the anatase structure of TiO2, the samples obtained by anodization were calcined at 450 degrees C and subsequently the copper oxide layer was deposited. In this study the structural properties were investigated by means of morphological x-rays by SEM measurements and optical properties through UV-Vis, Auger and Raman spectroscopy. In the X-ray measurements, the anatase phase is observed with secondary phases corresponding to the CuO. In SEM the uniform coating is observed for the method sample 2 to 60 minutes with CuO / Fe. In the measurements of Raman spectroscopy after calcination of the samples, the vibrational modes of TiO2 are obtained. In the Auger measurements, they indicated the presence of titanium in the Auger (L2M2,3M2,3) and (L2M2,3M4,5) transitions, located at 387eV and 418eV as well as Fe, O, C. Finally, our results suggest that TiO2 support -nanotubes / Ti with a CuO tank is promising for possible applications such as electrode.
